However, the Lighthouse Factory POSCO does not stop at simply leading the introduction of the Fourth Industrial Revolution technologies. What’s more? Here are the three factors that make POSCO stand out.

① Challenging the Impossible — POSCO’s Smart Blast Furnace

An unmanned storehouse or an automotive parts assembly factory run by robots could be the first thing that comes to mind when one hears the word ‘AI factory.’ Another might think that Artificial Intelligence could be applied only in specific areas, like the information technology industry. A blast furnace is a gigantic facility with a height equivalent to a 40-story building. On the inside, it is full of a mixture of solids and liquids, so turning it off or ‘looking’ inside seems impossible. Due to these many factors, applying AI to a blast furnace and making it ‘smart’ was considered nearly impossible.

POSCO stood up to this challenge. In 2016, the term ‘Fourth Industrial Revolution’ began to take its place in the industry. POSCO was one step ahead, but not in a hurry. It moved on to Step-by-step digitization and smartization with caution and care. At first, POSCO tried to do this with the technology of a global IT company but did not get satisfactory results. The new technology alone wasn’t enough. However, when POSCO’s unique expertise, intuition, and knowledge — along with its field experts — were combined with it, the advanced AI blast furnace could be born.

▲ The AI blast furnace is made with the combination of vast, sophisticated data, and the experience and intuition of POSCO experts. Deep learning enables optimal results and automates them to reduce human errors and increase productivity.

POSCO field experts — the technicians and engineers — standardized the main variables that determine the state of the blast furnace into Big Data. They enabled the blast furnace to conduct deep learning to extract optimal result value by imitating their know-hows accumulated for over 30 years. Facilities were also steadily improved so that the IoT could replace the manual work. As a result, POSCO boosted the daily production of molten iron by 240 tons. Additionally, workers could focus on advanced work for more creative performance. POSCO saved 250 billion KRW by carrying out 321 smart tasks — including the AI blast furnace — for the past four years.

Through the AI blast furnace, POSCO was able to break away from the old concepts of steel mills. POSCO’s “Technology for the automated control of blast furnace based on deep learning AI” is currently registered and protected as the National Core Technology of Korea (August 2019). POSCO is currently establishing smart factories not only in the blast furnace but also in the overall steelmaking, rolling, and surface treatment process and is creating high-quality smart steelworks.

② POSCO Smart Factory: A Collaboration Of Academia, SMEs, And Start-ups

There is another special feature behind the Lighthouse Factory POSCO — the collaboration of academia, SMEs, and startups in establishing the Smart Factory. As seen below, the World Economic Forum acknowledged POSCO’s effort in forming the collaboration model.

▲ A World Economic Forum article stating the reason POSCO was chosen as a Lighthouse Factory.

POSCO is actively cultivating AI experts in-house and is working with POSTECH for the cause. POSTECH has the best faculty of the artificial intelligence field in Korea. POSCO AI Expert Course, which began in 2017, is a program where selected outstanding POSCO personnel receive training from POSTECH professors. This course has resulted in more than 60 POSCO AI experts in three years. These AI experts are working to build smart factories in the work field.

The collaboration included SMEs and start-ups as well. POSCO developed the AI blast furnace with ‘ECMiner’ since 2016. ECMiner is an SME specializing in data mining*. It created a system that can automatically identify, analyze, and maintain the combustion condition of the blast furnace by combining its data mining technology with POSCO’s accumulated data. In the past, the combustion status was left to the manual labor of workers, checking through the wind hole, and judging by experience. However, with this system, the data can now be taken care of automatically. It also maintains the appropriate combustion level of the blast furnace, which reduces the amount of coal injected. This enables an overall cost reduction.
*Data mining: A technology that looks for hidden, valid, and potentially useful patterns in huge data sets, extracts feasible information, and makes decisions accordingly.

The collaboration resulted in a win-win for both POSCO and ECMiner. POSCO succeeded in creating an AI furnace with Korean technology, and ECMiner also benefited from the experience of processing huge amounts of data at POSCO. All academia, SMEs, and start-ups that participated in the building of POSCO Smart Factory, including ECMiner, can help construct a new one in another factory based on technology experienced at POSCO. This is expected to accelerate the proliferation of smart factories in Korea.

③ Sharing With The Industrial Ecosystem

The Lighthouse Factory POSCO shines brighter for the third factor. On January 9, Korean president Jae-in Moon visited POSCO Pohang works.  POSCO CEO Jeong-Woo Choi said:

“With the Smart Factory, POSCO has reduced production cost of 250 billion KRW for four years. And to relieve the wage gap with business partners, POSCO has extended an additional 270 billion KRW to outsourcing expenses for the last three years. Increased outsourcing expenses raises overall costs. However, POSCO is offsetting this through endless innovation. Through these measures, POSCO aims to foster the competitiveness of the whole industrial ecosystem, and then, in turn, enhance national competitiveness. POSCO’s management philosophy lies here.”

POSCO willingly shared the achievements of the smart factory project to solve the real problems many partner companies face. At first glance, this might simply seem like a ‘generous side’ of a large company, but in reality, this wasn’t an easy step. POSCO made this possible with its capacity earned through intense internal innovation. This is a good example showing how POSCO innovation isn’t just about POSCO.

POSCO went on to expand the benefits to SMEs who do not have direct business with POSCO. With the support service to build Smart Factory for shared growth, POSCO has provided the Smart Factory technology to 110 SMEs last year alone — 59 of which are companies with no direct business. The service will support 1,000 SMEs by 2023, with no limits to the subject. This is expected to increase the competitiveness of SMEs, which will, in turn, improve productivity and create new jobs.

▲ POSCO’s Smart Factory project not only increases POSCO’s competitiveness but also empowers the entire industrial ecosystem. It also helps in resolving current issues like narrowing the wage gap and creating new jobs.

This is what POSCO’s innovation is all about. The willingness to share with something that was earned hard. POSCO the lighthouse factory is indeed shining the light to a brighter future of the manufacturing powerhouse Korea.

POSCO is the first South Korean company to receive such recognition. Through its smart-factory platform, the company demonstrated its ability to leverage artificial intelligence to drive productivity and quality improvements in the steel industry.

How does POSCO drive impact by applying Fourth Industrial Revolution technologies? POSCO Newsroom reports.

l POSCO the Lighthouse Factory Shines Light on Manufacturing Industry

Lighthouse factories represent a range of industries that demonstrate leadership in applying Fourth Industrial Revolution technologies like IoT, cloud computing, Big Data, and AI, to drive financial and operational impact.
For the last five years, POSCO has laid the groundwork for the smart factory to boost its competitiveness in steelmaking. POSCO’s selection signifies global recognition of the company’s such effort.
From the submission of the application, due diligence, to documentation review by WEF consultant, the lighthouse factory selection is an arduous process. From the initial application submission, it took POSCO about one year until its final selection as the lighthouse factory.

One of POSCO’s esteemed contributions was its establishment of a sound ecosystem where SMEs and start-ups can thrive through active collaboration. Additionally, POSCO’s smart factory platform was customized to meet the needs of the steel industry. One of the WEF consultants at POSCO’s steelworks was especially impressed with the way in which years of human skills paired superbly with the new AI technology in monitor-controlling the massive furnace operations live, 24/7.

There are altogether 26 lighthouse factories around the world including POSCO, Siemens, BMW, Johnson & Jonson, and Haier. The lighthouse designation effectively gives the companies the Global Lighthouse Network membership among which the members share their knowledge and experiences enhancing their ability to better-adopt smart-factory platform. POSCO plans to utilize the benefits the Network offers to boost its ability to establish and advance smart factories that meet ever-changing industry demands.

l Sophisticated Steelmaking Goes ‘Smart’

Heavy pole and massive chimneys are some of the things that people associate with typical steelworks operation. What’s so complicated about steelmaking? — isn’t it all about stuffing everything in the blast furnace where molten iron comes out? Then molding the molten iron, baking it, pressing it, and cutting it up?

Maybe so, but in actuality, each process is extremely sophisticated especially when combined with varying customer requests. The smooth operation of POSCO’s 24/7 steelworks can be attributed to the company’s 51 years of experience as well as to the field engineers whose meticulous monitoring and management of the steelworks operation propel the steelworks operation forward.

Even with their expertise, however, each engineer’s experience varies. In the immense intricacy of steelworks operation, POSCO must deal with the inevitable at all times. What are some of the inevitable situations that can occur during the steelmaking process?

Production Planning: POSCO’s ‘Order Management Group’ is the brain of all steelworks operation — not only does it take orders, but it also manages production schedules, locations, and production methods. The Group is also in charge of figuring out precise production timing as per special customer requirements. Some customer requests involve a unique mixture of ingredients, so there are always many variables to consider. There are at least 10 ‘standard’ procedures the Order Processing Group must consider. Only after these minimum standards have been met, the steelworks operation of that specific order can receive greenlight.

Ironmaking: POSCO Newsroom previously covered the basic concept of managing ‘blast furnace condition’ in the ‘Blast Furnace Anatomy #1 — To the Heart of Steelworks Operation’ (LINK). There are countless tasks involved in 24/7 blast furnace operation — from maintaining temperature, placing in fuels and raw materials with precision, to predicting the amount of by-product gas generation.

Steelmaking & Continuous Casting: The steelmaking department removes impurities from the molten iron produced in the previous ironmaking stage, by way of converter — the molten iron becomes ‘steel’ in this process. During the casting process, the ‘steel’ is molded into intermediary materials like slab, bloom, and billet.

Molten iron can be made into countless different products to meet diverse customer needs, each requiring different portion and mixture of ingredients. To achieve this goal, the molten iron undergoes four different stages of ‘blowing process’ where oxygen is pressured through molten iron to lower the carbon content of the alloy, changing it into low-carbon steel.

At this point, the molten ‘steel’ goes through continuous casting, after of which is cooled down and cut. Temperature and ingredient management with precision is crucial for maximized use of limited resources.

Rolling: The next step is ‘tempering,’ a process of heat treating, which is used to increase the toughness of iron-based alloys. In ‘Game of Thrones’, blacksmiths constantly bang on the iron as a way of hardening the material. In steelworks, the process of rolling achieves the same goal.

In rolling, materials are passed through the rotating rolls to produce steel products that meet customer demands: in thickness, width, strength, durability, etc. Imagine baking bread, each with a different requirement for textures, tastes as well as shapes.

Surface Treatment: Automotive steel plates and home appliances are galvanized so that they become more corrosion-resistant, more suitable for various manufacturing purposes. Precise surface treatment suited to each purpose is the key to an advanced coating technology.

Notwithstanding the 100% effort aimed for perfection, complex steelmaking process overflows with information. Variation — be it human or mechanic — is inevitable in each and every step of the process. To address such variation, POSCO is opting for the smart factory, identifying it as the next-generation of its growth engine.

The establishment of smart factories must be preceded by the digitization of factories. Through Process Innovation Project (PI Project) in the 2000s, POSCO successfully achieved digitization of its factories. What set POSCO apart from the various similar endeavor is that the company has been working this digitization muscle for a while now. Smart factory, which is being built on the digital factory, is at the center of POSCO’s unique smart factory platform called PosFrame.

l PosFrame, the Foundation of POSCO’s Smart Factory

What is the origin of POSCO’s smart factory? It can be traced back to the year 2015 when the hype of smart industry hasn’t quite caught on the flame. Even back then, POSCO introduced new technologies like Big Data, specifically at the Plate Plant at Gwangyang Steelworks. At this point, Gwangyang became a testing ground for POSCO’s smart factory. During this process, the foundation for ‘PosFrame,’ POSCO’s unique smart platform, was created.

With PosFrame, POSCO could establish a system in which the company’s countless data and skills accumulated through the 51 years of its operation can be integrated and stored in one place.

How is this different from conventional digitization?

PosFrame is the world’s first smart factory platform specified for continuous manufacturing processes. The reason why ‘PosFrame’ is identified as a ‘platform’ is this: think of railway platforms. Railway platforms are where different types of trains pass through — be it bullet trains, express trains, or slower all-stop trains. A platform manages information about different types of trains — in this case, data — coming and going all the time. It’s a perfect system for 24/7 steelworks operation. The goal of PosFrame is to pinpoint the reason behind a product defect, if and when, by meticulously back-tracing the steelmaking process to figure out exactly where a variation might have occurred.

Furthermore, PosFrame goes beyond simple digitization. Whereas digitization simply stores information as data, PosFrame analyzes the data, enabling the development of automation models.
Here, a question might arise: isn’t automation something only reserved for experts? PosFrame’s ‘Workbench’ feature says no. Workbench is accessible to everyone. For example, field engineers can apply their expert knowledge and use the data to develop automation models so that the models can be utilized in various steelmaking processes. Thanks to the data collected and standardized by PosFrame, engineers can analyze information not only for the process they’re directly involved but also the processes that come before and after. PosFrame makes it easier for the engineers to tackle difficult issues that previously remained as random occurrences.

The incredibly accessible PosFrame accelerated POSCO’s advance into smart factories. Through PosFrame, all POSCO employees are turning into semi-AI experts.

To further its smartizaton process, POSCO has been providing smart tech training to all employees since 2017. The training is helping the employees take their skills to the next level towards establishing a more data-driven working environment.

Through the ‘POSCO the Lighthouse Factory #1,’ we introduced the core concepts behind POSCO’s smart factory. In the next episode, ‘POSCO the Lighthouse Factory #2: POSCO’s Smart Factory Transforms the Industry (The Cases),’ we will provide more concrete pictures on how POSCO’s smart factories operate. Stay tuned.

Using publicly available data, Corporate Knights examined about 4,000 companies with a market value of at least $2 billion. Their methodology looked at 14 key performance indicators (KPIs) covering environmental, social, and financial performance metrics. KPIs included energy efficiency, greenhouse gas emissions management, atmospheric environment management, water resources management, waste recycling, innovation capacity, tax rates, wage disparities, pension fund ratios, safety performances, turnover rates, diversity, and links between sustainability performance and compensation.

POSCO received high marks for its safety performance, water efficiency, waste recycling, and the levels of average employee wages compared to CEOs.

POSCO ranked first among other Korean companies with Shinhan Financial Group (40th) and LG Electronics (65th) also being listed on The Global 100. German conglomerate Siemens topped the list, followed by Storebrand ASA (Norway) and Cisco Systems Inc (USA). Johnson & Johnson placed 8th, Coca-Cola 48^th, and GE 99^th (see the full list).

These evaluations are significant in that they recognized POSCO’s efforts to secure a sustainable future despite increasingly difficult market conditions such as global over supply of steel, sluggish demand, and strengthening trade regulations.

In addition to The Global 100, POSCO has been listed on the SAM-Dow Jones Sustainability Index for 12 straight years (2005-2016), and World Steel Dynamics (WSD) has named POSCO the most competitive steelmaker in the world for seven years running since 2010.

Since 2005, the WEF has released the Global 100 Most Sustainable Corporations in the World Index (Global 100 Index) through Corporate Knights, the Canada-based media and investment advisory company. In the belief that corporate competitiveness and sustainability involve not only a company’s financial performance but also its contribution to environmental and social sectors, corporations are evaluated across 12 “key performance indicators” and ranked accordingly.

Receiving favorable evaluations in R&D innovation, energy efficiency and governance index, among others, POSCO maintains its leading position in the domestic manufacturing industry. Among Korean corporations, Shinhan Bank (18th), LG Electronics (44th) and Samsung Electronics (94th) also made the list. Meanwhile, BMW, the German automobile company, came in first while other global conglomerates such as Coca Cola (13th), Intel (38th) and GE (70th) followed.

Being selected as one of the top 100 corporations in 2016 is significant, as there were many difficulties in the market last year, including global oversupply, slumps in major industries and strengthened import regulations in export destinations. Furthermore, structural regulation was conducted for financial structure improvement.

Since 2005, the Davos Forum has been announcing the ‘Global 100 Most Sustainable Corporations’ (hereinafter referred to as Global 100) through the Canadian media-investment consulting company, Corporate Knights.

Corporate Knights examined companies with significant global market capitalization to select the Global 100. Companies were evaluated on 12 main indices, including energy productivity, innovative capacity, staff turnover, and staff versus CEO compensation. In order to achieve high rankings, companies must score well on social, environmental and financial scores, rather than solely on financial measures.

This year’s Global 100 lists four Korean corporations, including POSCO. After ranking 30^th, the best ranking ever for Korean corporations in 2012, but POSCO wasn’t included in the Global 100 for the two years following. However, POSCO re-entered at 36^th this year, as the first evaluation conducted since the inauguration of CEO Ohjoon Kwon. On the other hand, Samsung Electronics ranked 45^th, LG Electronics ranked 51^st, and Shinhan Financial Group ranked 70^th.

POSCO’s highest ranking of any Korean corporation on the list shows that it has been recognized for the efforts of its staff and executives to create a good workplace with reduced staff turnover through sustainable management. It also brought positive results in terms of transparency of information release, including the *ESG integrated report by POSCO affiliates implemented since last year. POSCO was highly praised for the way it has carried out added-value improvements, such as making steel by-products resources and reusing, and in enhancing innovative capacity through R&D investment.

Along with the selection in the Global 100, POSCO has been selected as an excellent corporation in the SAM-Dow Jones Sustainability Indexes for 10 years running, which is the first case for any company in the steel industry. In particular, POSCO has been awarded in three sectors; POSCO has won the ‘Industry Leader’ as well as the ‘Industry Mover’ who get the highest rated compared to last year, as well as ‘Gold Class’ for being in the 1% of industry leaders.

Meanwhile, POSCO was selected as the ‘No.1 steel competitiveness of the world’ last year by World Steel Dynamics (WSD), a global steel specialized analysis institute. It was the fifth time running to win the prestigious title. The WSD has conducted its evaluation based on 23 indices, including the size of production and profitability, technology innovation, price determination power, cost reduction, financial soundness and securing raw materials, among 36 steel corporations worldwide.

*ESG 
Since corporation results in the area of Environment, Social and Governance do not appear in the financial element, ESG is defined as the core evaluation element when deciding investment under the UN Principles for Responsible Investment.
