METHOD OF STEEL INGOT PRODUCTION Russian patent published in 1996 - IPC

FIELD: metallurgy, electrical slag reheating of metals in particular, method is used in process of remelting with change of electrodes being forge wastes separated from head part of forge ingots. SUBSTANCE: method provides for electrical slag remelt with change of electrodes, additional introduction of slag mixture before electrodes change and reheating of slag molten bath. Aim is to utilize forge wastes from head part of forge ingots. To realize the aim composite electrode made of the wastes is remelted. In the case introduction of additional slag mixture and reheating of slag molten bath are realized after remelting of 60 - 65 % along length of each waste from it lower part. EFFECT: method allows to utilize forge wastes from head part of forge ingots.
