POSCO is accepting applicants for the fourth round, offering free education courses on artificial intelligence, big data, and IoT for job seekers as well as the public.

Last year, POSCO along with Pohang University of Science and Technology (POSTEC) created education programs on AI, big data, and IoT in the form of basic online and advanced offline courses. The program comes as part of the company’s social contribution efforts offered free of charge to encourage these skills and broaden job opportunities.

Application for basic online courses are available for everyone until September 2 through POSTEC website. Upon completion of basic online courses, advanced offline courses are open to selected individuals for 10 weeks from September 3 through October 24 at POSTEC. To promote the offline program that provides intensive training in a short period of time, POSCO plans to actively promote these efforts in domestic universities and online communities for job seekers.

The four-month program is designed and carried out by POSTEC professors while equipment expenses are provided by POSCO. Basic online courses started out with six in the first round expanded to 13 this year. The first round of courses have ended on September 2. Over 6,000 students have completed basic knowledge on AI, machine learning, computational intelligence and more. POSTEC plans to take previous feedback into account to further enhance the quality of the courses.

The online programs on AI, big data and IoT were completed by 26,494 students thus far. The advanced offline courses completed by 49 students have successfully entered the domestic workforce  such as interns at POSTEC, regular employees at LG CNS, Kakao, and SK Innovation. POSCO plans to further advance the courses such as blockchain, cryptocurrency, and computer vision for students interested in even more specialized fields.

Meanwhile, Jeong-Woo Choi, who was elected as the 9th CEO of POSCO on July 27, presented ‘With POSCO(Building a better future together as corporate citizens)’ as a new vision at the inauguration ceremony, expressing his aspirations to create a better society through contribution. This program represents POSCO’s major social contribution activity, aimed at increasing job opportunities while enriching the country’s competency in the fourth industrial revolution.

Here’s a look at how steel is produced in a steel mill or factory, and what the “smartization” of steel factories will look like.

So, how is steel made?

Iron Making

To make steel, manufacturers first need molten iron. Molten iron comes from two raw materials; iron ore and coal. Iron ore is converted into sinter ore in a sintering plant and coal is converted into raw coke using a coke oven. The processed materials are poured into a blast furnace where hot air reaching 1200℃ is blown in from the bottom through tuyeres, causing a chemical reaction. This process oxidizes the coke and reduces the sintered ore, creating molten iron.   

Steelmaking

In the steelmaking stage, the molten iron is transported to the steel making plant via a torpedo car, where the liquid is poured into a converter. Then, oxygen is blown into the converter to burn off all the impurities. All that is left is pure molten steel.

Continuous Casting

This is where steel finally becomes solidified into different shapes such as slab, bloom and billet. Liquid steel is poured into molds and cooled as it passes through a continuous casting machine until it solidifies into the desired shape.

Rolling Process

During the rolling process, steel is heated once more to achieve various sizes and thicknesses. Steel slabs are heated to over 1100℃, then pass through rolling machines. This results in hot-rolled coils that can be shaped for different uses such as thick plates. They can also be processed into long, wire-shaped rods for billets. Often, the hot-rolled coils are rolled at room temperature for cold-rolled coils. Cold-rolled coils can be fabricated to produce galvanized and electrical steel products.

“Smartizating” these processes will involve converging IoT, Big Data, and AI to connect the different facilities, IT systems and workers in order to collect and analyze data for optimization.

POSCO is “smartizing” the steel-production process

POSCO is a steel company looking to lead the industry in adopting smart factories. CEO Kwon Ohjoon made “smartization” one of the 4 key priorities for POSCO starting back in 2014, and Kwon will continue to increase those investments.

In 2016, POSCO established its Smart Solution Council in order to research AI, big data and IoT applications. In the same year, POSCO ICT’s smart factory platform, PosFrame, was completed and installed in POSCO’s Gwangyang Steel Mill. PosFrame allows engineers to collect and monitor big data. So far, the company has saved over USD 14 million by incorporating the new technology in its production practices.

Here are some other features of POSCO’s Smart Factory.

POSCO’s Smart Blast Furnace

The Pohang Blast Furnace No.3 became a smart furnace in 2017, following a 102-day repair period. The furnace is now equipped with automated sensors that monitor and control its internal conditions using AI technology. Smart sensors monitor the blast furnace for factors like raw material quality and ventilator status, preventing breakdowns and ensuring a much longer lifecycle.

Worker Safety

Smart sensors can be used for more than just process monitoring. The company is working toward a full implementation of smart sensors for safety purposes, using IoT to create a better working environment.

Steel manufacturing involves high temperatures and high pressure levels, which is dangerous for workers who come in close contact with the equipment. With smart sensors monitoring all of the factory information, workers will instead be monitoring operation from a safe distance.

Workers in POSCO’s smart factory wear smart sensors for safety.

Wearable sensors, in conjunction with factory smart sensors, will be able to detect if and when workers are approaching potentially dangerous areas, and will alert them. These sensors will also detect and alert with regards to any impending accidents, or life-threatening situations like gas leaks, explosions, or fires.

Also, dust, sulfur, and nitrogen compounds will be removed via a high-plasma method, creating an eco-friendly steel plant and a healthier environment for workers.

POSCO will continue to add more smart features to its steel mills to increase efficiency, safety and sustainability. In efforts to learn and implement new technologies, POSCO CEO Kwon Ohjoon visited GE’s smart factories to learn about their technology earlier this year. POSCO also held the 2017 Smart POSCO Forum to share its insights with clients and affiliates, all as part of its expanding smartization efforts.

The fourth industrial revolution is heralded by big data, the internet of things, artificial intelligence, virtual reality and augmented reality, 3D printing and other technological innovations. It’s happening at rapid speed. The steel industry needs to keep up and take advantage of all that this revolution has to offer.

However, the industrial revolution did not happen overnight, and advancements in human development traces back to the Iron Age.  

The Iron Age and How it Impacted Civilization

After the Bronze Age was the Iron Age. People started using iron and steel for tools. This was a huge shift for the world, and helped improve nearly all spheres of life from the spread of written language to more effective agricultural practices. Iron offered more choice. People could forge this material into whatever they needed for tools, weapons, or ornaments and decor.

Blacksmiths would have used tools like this during the Iron Age.

Tools and weapons created during this era often used steel, which was a vast improvement on the bronze items from the previous age. Items made from steel were just as light as bronze, but stronger, so users were able to get more out of each item they created. The strength of these tools made it possible for farmers to plant and harvest more land, faster. It enabled people to sell or trade for livelihood.

The Iron Age is a great example of how the right materials can make life better for everyone.

The New Structure of Steel

As the world moves through the fourth industrial revolution, it is evident the same thing is happening. Instead of improvements in specific materials and tools, however, technology is changing things.

The steel production process can be completed autonomously if the fourth industrial revolution continues the way it is going. This means that manufacturers will be able to have very detailed and thorough control over production, using smart technology that will factor in every element from the surrounding environment to minute details of the material itself. The steel production process will be able to use real-time data to optimize every facet of operations, saving money and time.

The steel value chain is affected by changes in the provision of after-sales service, owing to new technology. Manufacturers can use smart technology to track how users interact with their completed products and offer better customer service as a result.

Again, real-time information comes into play, allowing steel companies to see exactly how orders are being created, fulfilled and used, as it is happening. Customer needs are met with ease and speed, all tracked and analyzed digitally.

Competition in the steel industry will be affected by this revolution, too. Competitors can see how other companies are using big data and automation to save money and offer a better customer experience, and use those details to revolutionize their offerings. Online steel transaction platforms make this transparency even more accessible, for companies and clients alike.

Implications on the Steel Industry

To keep up with this revolution, and make the most of it, steel companies need to understand the implications on the industry and plan for the future. New technology is only going to become more widespread, more common, and more advanced. Companies need to be ready to react.

Integrating technology and smart software is the ideal way for steel companies, and the industry at large, to take advantage of this new revolution and use it to create better products and better customer relationships.

To get an idea of how to best integrate new tech into existing steel practices, POSCO’s smart steel factory is a prime example, currently being tested at the Gwangyang Steel Mill. POSCO’s smart factories will collect and analyze all of the microdata generated in the steel production process, to determine the cause of every event that impacts quality or production in general.

An image of how POSCO’s Smart Factory will be run.

From facilities to energy and environment, to safety and conditions, the smart factory will monitor everything. And it will respond accordingly to make the best quality steel possible.

Self-learning artificial intelligence ensures that the process of steelmaking is carefully controlled, with adjustments made in real-time to directly and positively impact the result. The smart factories will use technology to fill the gaps where human capabilities are simply no match for software.

The world has come a long way since the Iron Age and through the various industrial revolutions. In the current fourth industrial revolution, steel companies have to take advantage of new technology and innovations by figuring out ways to apply them to steelmaking processes. POSCO has made this a top priority as it continues to research, educate and implement smart technologies to its production processes and materials and will lead the way for steel companies to follow through the fourth industrial revolution.

We are entering a new era of manufacturing, one in which computers and machines are coming together to perform automated actions. Even more impressive, they are able to do this with less and less human involvement, learning from their mistakes and teaching themselves to constantly perform better.

Smart factories operate autonomously as the machines talk to each other through sensors – reducing faulty products and waste.

This new era, what is being called Industry 4.0, is one in which manufacturing moves beyond some of its former limitations by becoming more efficient, less wasteful, and much more productive. Corporations like Siemens, BASF, GE, and POSCO are leading the way by designing smart factories connected through IoT technology and artificial intelligence that produce higher quality products with less waste.

Industry 4.0 and the Smart Factory

The First Industrial Revolution marked the movement from pure human labor to using machines. Steam engines also appeared helping move things along further and more quickly. Next came electricity, and with it, mass production. The Third Industrial Revolution saw the rise of computers, more automation, and the replacement of some human labor. Now, we are entering the Fourth Industrial Revolution, or Industry 4.0, in which these machines interact and learn from each other with little to no human interference.

With Industry 4.0 we are seeing the smart factory. A smart factory is a physical manufacturing system connected by AI, IoT, and tons of data in the cloud that teach the systems to work by themselves and make improvements without human involvement.

Bernard Marr says that for a factory to be considered Industry 4.0, it must include:

• Interoperability — machines, devices, sensors and people that connect and communicate with one another.
• Information transparency — the systems create a virtual copy of the physical world through sensor data in order to contextualize information.
• Technical assistance — both the ability of the systems to support humans in making decisions and solving problems and the ability to assist humans with tasks that are too difficult or unsafe for humans.
• Decentralized decision-making — the ability of cyber-physical systems to make simple decisions on their own and become as autonomous as possible.

In the examples below, we can see how three corporations are bringing these pieces together to advance smart factory production. Siemens, GE, and BASF have all utilized this technology to build a more efficient production system, and POSCO is doing the same in its steel production line.

Siemens, GE, and BASF – Case Studies in Smart Manufacturing

Siemens

The Siemens AG plant in Amberg, Germany, is unique in that it not only produces automated machines to be used in other industrial factories, but that it does so using fully automated machines in its fully connected smart factory. With over 1,000 manufacturing units connected via the web across 100,000 square feet, each step of the manufacturing process is automated and programmed to make customized products immediately.

The plant, established in 1989, is currently operated with around 1,200 employees and about 75% of operations are automated. The plant manufactures more than 12 million programmable logic controls (PLCs) that are used to automate cruise ships, automobile production lines, and ski lifts to name a few. With production quality at an impressive 99.99885%, an inspector would be hard pressed to find any defective products.

While Siemens has largely automated the production process, workers are still needed in the beginning to place the circuit board on the production line and supervise it through its production cycle. Producing more than 1,000 product variants for over 60,000 customers worldwide, Siemens has developed a model smart factory with automated systems creating nearly perfect products with less waste.

BASF

At BASF, the chemical giant incorporated a smart factory system so that it could manufacture fully customizable soaps and shampoos. When an order is placed, the automated factory line adjusts its protocols to make the unique product and packaging that was ordered by the customer. The set up is automatic and the quality is near perfect.

At its smart pilot plant in Kaiserslautern, Germany, once an order is placed for a personally customized soap or shampoo, radio-frequency ID tags that are attached to the soap containers send out wireless signals. These wireless signals tell the machines on the production line about the customized order.

The setup and manufacturing process is automated, exact, and with near perfect quality control.

GE

At GE’s Advanced Manufacturing Works in Greenville, South Carolina, engineers are working on new ways to streamline smart factories using AI and IoT technology. This $75 million plant sits next to where GE makes the world’s largest gas turbines – products manufactured on a huge scale with incredibly intricate pieces. They have introduced smart factory systems into this factory and are working to provide more to its other plants around the globe.

Staffed with 80 engineers, PhDs, and machinists with decades of experience – they will use the Advanced Manufacturing Works to try new manufacturing and design ideas in order to streamline the production processes of other factories.

POSCO Implements AI Into Its Smart Factories

POSCO CEO Ohjoon Kwon recently visited Siemens and GE to compare their work in smart factory systems with POSCO’s. All three of them are working on vastly different products; however, the ideas behind the technology are similar.

At POSCO’s Gwangyang Works, they have installed a data integration infrastructure that encompasses all of its operations and facilities. This technology uses an automated control technology that predicts the coating weight of zinc in automotive steel in real time to precisely control the Continuous Galvanizing Line (CGL), the primary technology used in automotive steel sheet production. In combination with the coating weight system, they have also created a data pre-analysis system that can preemptively detect abnormalities.

POSCO’s smart factory systems have improved quality and reduced waste

Coating weight control is a highly-sophisticated technology that keeps the thickness of the coating layer consistent – even when operating conditions change suddenly. When coating weight is controlled manually, quality deviates depending on the skill level of the worker, inevitably resulting in significant amounts of wasted zinc. However, the plating process is now automatically controlled by artificial intelligence, increasing the quality of POSCO’s automotive coated steel while decreasing production costs.

Also, in order to apply smart technologies more quickly, POSCO Group University is partnering with POSTECH (Pohang University of Science and Technology) to build an AI ecosystem that nurtures AI specialists and fosters advanced research. POSCO Group University will be in charge of launching related training programs POSCO and its subsidiaries, while POSTECH Information Research Laboratories (PIRL) will be in charge of developing content for basic and advanced courses to increase people’s understanding of AI, big data, programming, pattern recognition, machine learning, natural language processing, and computer vision. This partnership will serve as a significant milestone in expanding cooperation between companies and academic institutions, a fitting move in the era of the Fourth Industrial Revolution.

POSCO, Siemens, GE, and BASF are all utilizing the connected technologies of Industry 4.0 to move their industries forward. GE recently estimated there will be over “50 billion connected devices by 2020 and that the Industrial Internet could add $15 trillion to global GDP in productivity gains over the next 20 years.” Despite the industry barriers facing steel companies, POSCO is leading the industry in implementing connected technologies that will help them build the smart factories of the future and remain competitive for years to come.

Smart Cities automatically detect cars, adjusting traffic lights to optimize flow. Smart Homes know when to turn the lights on and off or when to order more groceries. And Smart Devices track people’s movements, their biorhythms and more, so people can better take care of their health.

The Internet of Things (IoT) can also be elegantly simple. For example, Amazon has launched the innovative Amazon Dash, a simple, Wi-Fi-enabled button that can be attached to items around the home, and with a press it orders more of that item. Amazon Dash can be used to order paper towels, diapers, laundry detergent and other commonly used consumer products, connecting your home, making it smarter, and adding a new kind of convenience.

The Internet of Things (IoT) has come to POSCO, too, particularly when it comes to safety. As part of an approach to developing solutions called POSCO’s “Smart Safety,” POSCO is using the Internet of Things to improve safety awareness, reduce risks and get all our employees invested in being actively involved in safety.

POSCO’s Smart Safety Case Studies: Wearables to Ensure Safety

The current focus for improving safety in the workplace focuses on removing risks and raising awareness, to change people’s habits and sense of ownership. By combining these activities with the IoT, POSCO is looking to provide more scientific and efficient solutions.

Two case studies highlight the potential power of POSCO’s Smart Safety approach. One is using Internet of Things (IoT) technology to protect against gas leaks in factories. To guard against dangerous gases, POSCO uses sensors, constantly checking the air to make sure it is not poisonous or suffocating.

By connecting these sensors to employees’ smart watches, POSCO is able to increase the intelligence and speed of these safety networks. When a sensor detects a dangerous gas, it can immediately connect to everyone’s wearable devices, so they can instantly learn there is a problem and quickly get clear of the danger zone.

In addition, by analyzing information about the gas leak, the factory safety systems can automatically determine where the leak is originating and block the valves around it.

For the second case study, POSCO proposed adding additional sensors and safety equipment to employees’ clothing, giving them additional IoT protection even when working alone. In the hard hat, an accelerometer and other sensors could be added to monitor each person and protect against falls, gases and other dangers. In the safety vest, biosensors monitor heart rate, body temperature and other personal conditions. And a GPS sensor in the safety vest could ensure the company knows where its employees are, to better ensure their safety during an emergency.

By making our employees’ clothes into smart clothes, we can greatly increase awareness of and responsiveness to potential problems, which means reducing risk and keeping all workers safer.

Using Competition to Get Everyone Involved in Safety

POSCO has also worked to get everyone more involved in promoting safety through a Smart Safety Idea Competition. The entire company participated in this contest, held from March 21 to April 10, with 1,072 ideas officially submitted.

Among the ideas about how to incorporate IoT technology to improve safety were using location-based services to monitor workers in the factory; risk-monitoring on large vehicles like cranes and handling equipment; wearable devices to monitor worker health; and using aerial drones to monitor for gas leaks.

Employees’ strongest ideas will be picked, judged on effectiveness, realism, economics and related criteria. The winners of the safety competition will be announced in June.

Embracing Technology to Always Put Safety First

POSCO has long been an innovator in the steel industry, always looking to use the latest technology to create the best-possible products. And it’s no different when it comes to safety—any and all tools are welcome if they can help make the POSCO workplaces better for our employees.

The Internet of Things is transforming our world, making all sorts of everyday objects smarter and more connected, and that’s an innovation that can make a real difference in the steel industry. By being at the forefront of implementing the latest technology into a new safety paradigm, POSCO is showing its dedication to becoming “POSCO the Great.”
