METHOD OF SMELTING OF THE HIGH-MANGANESE STEEL Russian patent published in 2008 - IPC C21C5/52 

FIELD: ferrous metallurgy industry; other industries; methods of production of the high-manganese steels.

SUBSTANCE: the invention is pertaining to the field of the ferrous metallurgy industry and may be used at production of the high-manganese steel. The method includes the remelting in the capacity of the charge materials of the low-grade manganese-containing the spoil breakage in the amount of 35-75 mass % together with the own return breakage out of the high-manganese steel in the electric arc furnace of the direct current. Exercise the layered charge into the furnace of the charge materials and the calcium fluoride in the certain succession. At smelting-down of the charge materials in the electric arc furnace maintain the maximum electrical mode, not allowing the bubbling of the molten bath. At usage of the invention ensures the saving of manganese at the expense of utilization of the low-grade manganese-containing spoil breakage.

EFFECT: the invention ensures the saving of manganese at the expense of utilization of the low-grade manganese-containing spoil breakage.
