<p>PROBLEM TO BE SOLVED: To provide a melting method of stainless steel scrap which can resolve problems of the lowering of heat efficiency and the increasing of chromium oxide content in molten slag, at the time of melting the stainless steel scrap by using an electric furnace. SOLUTION: At the time of melting the stainless steel scrap with the electric furnace 1, the molten slag is produced in a ratio of 100-300kg/ton of scrap and carbonaceous material 7 is made to be existent by 10-30wt.% per the molten slag quantity. Further, one or more kinds among nitrogen, Ar, CO2 and CO are supplied at 100-400Nl/min.</p> |
