POSCO has been ranked as the world’s most competitive steelmaker for seven years in a row. It has remained competitive in part by focusing on its World Premium Products, which offer advanced steel solutions for their customers. POSCO has also put extensive effort into maximizing its non-steel technologies and products to find new growth in non-steel sectors. In addition, POSCO has been a leader in innovating its own manufacturing processes, incorporating advanced AI and IoT technologies into its smart factories. POSCO has also remained committed to not only growing its non-steel secondary businesses, but advancing upon existing technologies to create new and eco-friendly production methods.  Below we take a closer look at how POSCO has continued its work to innovate and stay competitive.

POSCO Expands Lithium Manufacturing Business

Amid the rising demand for rechargeable lithium-ion batteries used in smartphones, laptops, and electric vehicles, POSCO has been working on proprietary technology for lithium extraction. Earlier this year, POSCO opened Korea’s first lithium plant, PosLX, and commercialized the production of lithium carbonate from rechargeable batteries after 7 years of development.

The PosLX Plant is expected to produce 2,500 tons of lithium carbonate per year using a new eco-friendly technology, which is enough to manufacture about 70 million laptop batteries. This output will supply POSCO’s battery making partners LG Chem and Samsung SDI, as well as POSCO ESM, a subsidiary that produces cathodes for secondary batteries.

POSCO incorporates AI into Smart Factories

POSCO is also breaking through technical barriers by designing smart factories connected through IoT technology and artificial intelligence (AI) that produce higher quality products with less waste. POSCO has also begun incorporating advanced AI technology into its smart factories in order to more efficiently manufacture automotive steel.

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

In particular, the ‘Smart Solution for Coating Weight Control Based on AI‘ technology uses an automated control technology that predicts the coating weight in real time and accurately meets the target coating weight. When coating weight is controlled manually, quality deviates depending on the skill level of the worker, which inevitably results in significant amounts of wasted zinc. However, when it is automatically controlled by AI, the quality of POSCO’s automotive coated steel can be enhanced while production costs are decreased. These new automated processes have also helped increase work efficiency and productivity with workers.

Also, CEO Ohjoon Kwon recently visited Siemens in Germany and GE in the U.S., both of which are known to have successfully operated advanced smart factories to observe how other companies have implemented highly sophisticated smart factory models. Through close cooperation with POSCO’s major affiliates such as POSCO E&C, POSCO Energy, and POSCO ICT, Kwon aims to embrace smart technology and reorganize POSCO’s entire business structure (Smart Factory, Smart Buildings & Cities, and Smart Energy).

POSCO’s Thailand CGL, Southeast Asia’s First Automotive Steel Sheet Plant

Faced with sluggish growth due to the oversupply from China and a decline in steel demand, POSCO has been looking to expand sales in new markets. In a bid to become the world’s largest steel provider for automobiles, POSCO completed its Thailand CGL (Continuous Galvanizing Line) in 2016. The plant has an annual production capacity of 450,000 tons and incorporates some of the most advanced AI technologies in its smart factory system.

In addition to being one of the strongest automotive production bases in Asia, Thailand is also the center of the consumer-electronics industry in Southeast Asia.

With the newly established automotive steel plate plant in Thailand, POSCO’s global volume will reach over 9 million tons in 2017 and more than 10 million tons per year starting in 2018. The automotive steel sheets manufactured by the facility will be supplied to global auto parts companies and carmakers operating in Thailand including Toyota, Nissan, and Ford. Despite the increase in competition from other steelmakers, POSCO aims to become a market leader through building strategic partnerships with global automakers operating in the country.

As cities around the world get more crowded, urban dwellers are facing more and noisier neighbors. To help combat this problem, POSCO introduced PosCozy in 2016, a unique flooring system that combines manganese (Mn) Z-clips with continuous galvanized steel plates that greatly reduce impact noise, save space, and lower costs (product video).  

Unlike conventional flooring that uses non-steel materials such as styrofoam insulators and rubber buffer materials, POSCO’s floor plates are developed by combining high Mn steel Z clips – a material that is 4 times more vibration-resistant than general steel – giving it the ability to reduce noise between floors. PosCozy is able to reduce the sound of typical walking from 50dB to just 40dB, while impact sounds are lowered from 58dB to 38dB.

PosCozy is the world’s first high manganese steel floor plate with first-class floor noise reduction.

PosCozy is the world’s first high manganese steel floor plate with top quality floor noise reduction. It is also the first flooring system to receive the highest rating in sound insulation from Korea’s industrial rating agency.  Due to its unique and superior qualities, PosCozy won the prestigious Jang Young Sil Award in 2016.

POSCO’s High Manganese Steel Used in the World’s Largest LNG-Fueled Bulk Carrier

Due to the rising number of shipbuilding orders for large-sized liquefied natural gas (LNG) carriers, there has been a shortage of nickel,  requiring new and innovative solutions to construct LNG-fueled ships. In order to address these issues, POSCO developed a new type of high-performance manganese steel and announced in 2016 that it would be applied to the LNG-fueled bulk carrier built by Hyundai Mipo Dockyard.

Developed independently by POSCO, this high manganese steel contains an Mn content of 20%. Compared to traditional materials, it boasts improved performance through unique properties that include high strength, low-temperature toughness, wear resistance, non-magnetic, and damping properties.

It is the first time a bulk carrier will have been constructed to include an LNG-fueled system and a fuel tank made of high manganese steel.  Its higher strength, ability to withstand an extremely low temperature (-162℃), and cost competitiveness make it superior to the nickel and aluminum alloys that are typically used in tanks. The ship, which will be the world’s largest LNG-fueled bulk carrier, is expected to have a capacity of 50,000 tons, seven times more than previous ships.

POSCO’s high-performance manganese steel will be applied to the world’s largest LNG-fueled bulk carrier built by Hyundai Mipo Dockyard.

POSCO has been able to overcome immense barriers, from the nickel scarcity in the LNG market to the oversupply of steel from China. POSCO strives to be a pioneer across all industries with its innovative products and will continue to do so in the years to come.

As cities around the world grow ever more crowded and city planners try to rein in urban sprawl, people are increasingly turning to apartment buildings for their homes. But while apartment complexes have many conveniences and advantages, one drawback is often noise, as everyone needs to deal with the footsteps and other sounds of life going on in the apartment above. Or, rather, that was a drawback.

POSCO has now introduced PosCoZy, a unique flooring system to combines manganese Z-clips with continuous galvanized steel plates to create floors that greatly reduce impact noise, save space and lower costs.

Leading Noise Reduction

Manganese Z-clips have four times higher resistance to vibrations than general steel. Combined with POSCO’s continuous galvanized steel plates, the PosCoZy flooring is able to significantly reduce the impact noise between floors in apartment buildings.

PosCoZy is the first floor system to receive a First Class silence rating from Korea’s industrial rating agency. This vibration-dampening reduces the sound of typical walking from 50 decibels to just 40dB, while impact sounds are lowered from 58dB to 38dB. In other words, PosCoZy is able to turn the noise levels produced by running children into something more akin to the quiet you’d expect in a library.

This manganese steel floor plating is also good for remodeling old structures, even those more than 15 years old with thin flooring, producing 4^th Class Noise Absorption Performance.

Space Savings for Improved Efficiency

In apartments, space is usually at a premium – not sure floor space, but vertical space as well. Thicker floors mean less spacing for living in. However, PosCoZy is thinner than typical flooring, reducing floor thickness by 15 millimeters.

In addition, the manganese Z-clips that support the galvanized steel plating create open spaces under the floor, creating room for piping, LAN cables or other wiring to run. Furthermore, the strength of the steel plates as flooring increases the floor’s capability to hold heavy loads, lasting longer without deformation.

More Economical, to Save Money

A third important advantage of PosCoZy is that it’s economical. The air layer formed in PosCoZy, along with heat insulation, prevents thermal loss and improves heating speed, improving the thermal capabilities. All together, that translates into savings in heating costs, which saves people money.

Silent, efficient and economical – those are the remarkable advantages that POSCO’s exciting new innovation in steel flooring offers builders and consumers. For more information about all the advantages of PosCoZy and high manganese steel flooring, check out the full video below:

Unlike conventional flooring that uses non-steel materials such as Styrofoam insulators and rubber buffer materials, POSCO’s floor plate is developed by combining high manganese (Mn) steel Z clips – a material that is 4 times vibration-resistant than general steel – with POSCO’s hot-dip galvanized steel plate, making it capable of reducing noise between floors. The Z-shaped high manganese steel clips absorb the vibration energy applied to the floor, and thus preventing noise. Test results showed that POSCO’s high manganese steel floor plate revealed a noise level that is lower than other top grade floor plates (43㏈or lower for lightweight impact sound, and 40㏈ or lower for heavyweight impact sound).

The floor plate made of high manganese (Mn) steel was jointly developed by POSCO and POSCO E&C beginning in June 2014. After acquiring state-registered performance certification last November, POSCO is currently promoting its steel product for apartment buildings, and will increase its market share in premium housings with on-site pilot projects.

“We are currently developing technologies to apply the high manganese steel plate not only to floor plates, but also to ceilings and walls,” said Youngdong Yoo. “We plan to expand the application scope of this product to various industrial fields beyond the domestic and overseas construction markets, such as ships and home appliances as well.”
