METHOD OF HIGH-MANGANESE STEEL MELTING BY REMELTING METHOD Russian patent published in 2024 - IPC C21C5/52 C22C38/04 C21C7/00

Abstract RU 2819765 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used in production of high-manganese steel in electric arc furnace with main lining by remelting method. Charge materials of own return scrap from high-manganese steel are remelted together with manganese-containing scrap in electric arc furnaces. Slag liquefier flux is added to charge together with limestone in amount of 5 kg/t of charge, by guiding a highly basic slag, a dispersed diffusion aluminium-containing deoxidizer is added in amount of 6 kg/t of liquid steel, upon completion of deoxidation and finishing of the melt, out-of-furnace treatment is carried out in a ladle with a refining mixture in amount of 5 kg/t of liquid metal.

EFFECT: invention allows reducing manganese waste, melting time and power consumption, and also improves mechanical properties of steel.
