FIELD: converter process with use of oxygen lance.
SUBSTANCE: proposed method is used for converter processes such as AOD, MRP, AOD-L, MRP-L, CLU, ASM, Conars-Stainless steel, or vacuum processes such as VOD, SS-VOD, RH and RH with use of oxygen lance. Slag formed at the end of blowing and treatment in converter or vacuum plant is drained and removed in unreduced state; this slag is fed to electric furnace which is loaded with standard charge consisting of metal scrap and residual dust; then carbon is additionally fed and silicon if necessary; during melting, chromium oxide contained is slag is reduced by means of carbon and silicon.
EFFECT: low cost of process.
