Steelmaking process

(1) Alloy and vice material are transferred to EAF for melting scrap steel. Ultra-high power EAF melts alloy and scrap steel by 3 groups of graphite electrode.

(2) The AOD blows specific oxygen/argon mixed gas for decarburization. Impurities are removed. It makes molten steel with qualified components and temperatures.

(3) Molten steel is stirred by blowing argon before casting. Then it is transferred by ladle turret with a specific temperature. The caster makes qualified molten steel into STS slab.
