Iron and steel production is generally divided into three areas. The 1st area is the blast furnace area, where ironmaking of
iron ore, coking coal, and other raw materials is carried out in an integrated manner. The 2nd area is the electric furnace area,
where steelmaking and steel products are produced by melting iron and steel scraps and removing impurities. The 3rd area is
the special steel furnace area, where high-grade steel with special functionality is produced by adding rare metals, etc. In recent
years, due to soaring raw material prices and declining selling prices as a result of demand for steel remaining high, improving
profitability through streamlining of manufacturing processes and stable operation has become an issue for the industry.
