低钛高炉渣应用于HRB400E螺纹钢100t LF精炼的工业试验
采用喷吹CO2法对低钛高炉渣进行脱硫处理,低钛高炉渣中硫的脱除率为66.59% ~78.01%,渣中残硫含量为0.137%~0.283%,所制备的低硫低钛高炉渣中硫含量基本满足HRB400E钢LF精炼渣要求.低硫低钛高炉渣LF精炼终渣成分为/%:37.40 ~ 46.50CaO,12.30 ~ 15.10MgO,21.70~ 26.70SiO2,5.74 ~ 17.00Al2O3,2.44 ~3.39TiO2,0.36~1.42MnO,0.75~1.62Fe2O3,0.200~0.597S,钢水脱硫率为10.0%~41.5%,HRB400E钢终点[S]为0.008% ~0.029%,与现工艺精炼渣(折渣和钢包渣终渣成分/%:34.30 ~ 42.90CaO,13.60 ~18.10MgO,24.00 ~ 26.50SiO2,4.88 ~ 11.00Al2O3,0.71 ~ 1.12TiO2,0.47~1.47MnO,0.81 ~ 1.72Fe2O3,0.245 ~1.132S)的脱硫效果相当(HRB400E钢终点[S]0.027% ~0.032%).
