Abstract

Abstract: Test and study on demanganization of hot metal by using 1 kg molybdenum-wound furnace and 10 kg induction furnace show that high [Si] ( ≥0.22% ) , low slag basicity (R≤0.65) and lower temperature are available to demanganization of hot metal ； as hot metal temperature T = 1280 °C , slag basicity R=0.44, (FeO)=11.36% and ( MnO)= 6.62% , the manganese distribution ratio between slag and metal L_Mn = 275.83, the demanganization rate η_Mn =92.94% and end [Mn] =0.024% to meet the requirement of Mn content in high-pure pig iron.

摘要： 通过1 kg钼丝炉和10 kg感应炉铁水脱锰的实验研究表明,高[Si]i(≥0.22%)、低炉渣碱度(R≤0.65)、低温有利于铁水脱锰。当铁水温度T=1280℃、R=0.44、(FeO)=11.36%、(MnO)=6.62%时,锰在渣铁间的分配率L_Mn=275.83,脱锰率η_Mn=92.94%,终点[Mn]=0.024%,满足了高纯生铁对锰的指标要求。
