Mn Ore Smelting Reduction Based on Double Slag Operation in BOF

Abstract:

This paper aims at finding a way to increase the rate of Mn yield in Mn ore smelting reduction process based on double slag operation in BOF. The thermodynamics of the process was analyzed and the experiments including slag-steel reaction in lab and steelmaking simulation in pilot plant were carried out. The results above were proved to be valid in industrial scale experiment in general steelmaking factory of WISCO. The industrial scale experimental results showed that 35%~50% of Mn yield could be obtained with conditions of higher temperature and high carbon content at the end point in conventional BOF process based on double slag operation, which can benefit to the efficiency of BOF process as well as less carbon emissions.
