KS Posco Cilegon
operatingPT Krakatau Posco · BF–BOF Integrated route · Cilegon, Asia Pacific, Indonesia
KS Posco Cilegon makes steel by the integrated route: iron ore is smelted into liquid hot metal in a blast furnace, then refined into crude steel in a basic oxygen furnace. The liquid steel is solidified into semi-finished shapes by continuous casting. The plant has a crude steel capacity of about 3.0 million tonnes per year. Its main products are slab, pig iron, cast iron, plate.
