STEEL FOUNDRY PROCESS Russian patent published in 1997 - IPC

Abstract RU 2096491 C1

FIELD: ferrous metallurgy. SUBSTANCE: process includes smelting steel in steel-smelting assembly, deoxidation, alloying, producing liquid metal containing silicon and aluminum reducing agents, adding oxide mixture containing calcium and manganese oxides in the ratio 0.6 to 1.2, keeping liquid material in ladle under slag with basicity corresponding to CaO/SiO2 ratio from - 0.7 to 1.8 arising after manganese is reduced by silicon and aluminum dissolved in metal. EFFECT: enhanced efficiency of process. 2 cl
