A method for recovering metallic chromium from slags which contain chromium oxide from converter processes, such as AOD, MRP, AOD-L, MRP-L, CLU, ASM, Conarc stainless steel or vacuum processes, such as VOD, SS-VOD, RH, RH with lanze, includes drawing off the slag which is produced at the end of a blowing or treatment operation in a converter or a vacuum installation in unreduced form. The slag is charged into an electric furnace, which is also charged with a standard charge of scrap and, if appropriate, dust residues. Carbon and, if appropriate, silicon are additionally added to the electric furnace. |
