【摘要】 本文通过钼丝炉上1Kg铁水和感应炉上10Kg铁水的实验,研究了炉渣碱度、铁水温度对铁水预处理同时脱钛硅锰的影响。研究表明铁水中钛硅的氧化基本不受铁水温度和炉渣碱度的影响,锰的氧化受铁水温度和炉渣碱度的影响较大,低温、低碱度有利于铁水脱锰。当铁水温度T=1280℃,R=0.44,铁水中钛硅锰可分别脱除至[%Si]=0.011,[%Ti]<0.005,[%Mn]=0.024,满足了高纯生铁对锰的指标要求。更多还原

【Abstract】 Based on the test of 1kg hot metal in molybdenum-wound furnace and 10kg hot metal in induction furnace,the influences of slag basicity,temperature of hot metal to simultaneous desiliconization and removing Mn and Ti had been studied, and the removal behavior had been systemically analyzed.The results show that temperature of hot metal and slag basicity do no contribution to the simultaneous desiliconisation and removal of Ti,lower temperature and lower slag basicity are available to demanganization.as hot metal temperature T=1280℃,slag basicity R=0.44,end[Si]=0.011%,end[Ti]<0.005%and end [Mn]=0.024%meet the requirement of Mn content in high-pure pig iron.更多还原
