Study on Smelting Technology of Medium and High Mn Molten Iron
JIN Lishan
Abstract：Some problems included hot metal splash, low residual Mn content at smelting end point, difficult control of smelting operation and etc, were existed in BOF smelting used of high Mn molten iron as raw material. Through fully using the relationship characteristics of end point Mn with basicity in slag and iron oxide, optimizing smelting operation, the aim of enhancing residual Mn content in smelting and stabilizing smelting operation was achieved. The residual Mn content at end point was raised from 0.125%to 0.196%, and the utilization factor of Mn in molten iron was increased and the alloying cost in the late was reduced.
