HIGH-MANGANESE VANADIUM-BEARING CAST STEEL SMELTING METHOD

摘要

SUMMARY OF THE INVENTION: to increase the cold resistance, increase the durability of cast parts and increase the degree of assimilation of manganese and vanadium during the melting period, the concentration of silicon in the metal is adjusted to 0.65-0.90%, the concentration of manganese to .7.5-9.0%, and during the refining period, the slag is treated with crushed carbon-containing materials in portions of 4-6 kg / m of bath area after 5-10 minutes for 15-30 minutes. 2 tab.
