The development is the fruit of its four-year-long research & development (R&D) at a cost of 55 billion won ($48.2 million) since 2013.
Normally, high manganese steels are made by pouring solid high-purity FeMn into iron mold in an electric arc furnace. The method requires significant time and cost during the process as iron mold needs to be cooled and warmed up again. In addition, the welding process can damage the inner wall of the furnace.
Posco developed specially designed heat reserving storage dubbed PosLM (Posco liquid manganese) to store high-purity FeMn in liquid form. Using the storage to pour liquid high-purity FeMn into the furnace will boost efficiency by 10 percent and cut processing time by half.
Steel with high percentage of manganese is mainly used for inner parts and body of industrial power transformers and also liquefied natural gas (LNG) storage tanks because of its excellent resistance to wear and abrasion.
