为探索转炉采用石灰石代替石灰造双渣脱磷工艺,在首秦100t转炉上进行了石灰石与石灰造双渣对比试验。试验结果表明:对比石灰双渣工艺84.4%的终点脱磷率,石灰石造渣炉次的终点脱磷率平均为88.67%;石灰石双渣工艺平均入炉CaO量减少约29.45%,可进一步降低物料消耗及渣量;随着石灰石加入批次增加,炉次脱磷率升高。 In order to explore the converter limestone instead of lime to make double slag dephosphorization process, Shouqin 100t converter on the limestone and lime made double slag comparative test. The experimental results show that the end point dephosphorization rate of 84.4% of the lime double-slag process is 88.67% on average, and the average lime removal rate is about 29.45%, which can further reduce the amount of material Consumption and slag volume; with limestone added batch increases, the furnace dephosphorization rate increased.
