摘要
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 process of converter using limestone instead of lime and double-slag for dephosphorization,the test results of 100 tconverter using limestone and double-slag in a steel plant were studied,and the advantages of limestone slagging for dephosphorization are analyed theoretically.The test results show that the dephosphorization rate of test furnace is 88.67 % on average.Compared with lime and double-slag process,the average CaO charging amount of limestone and double-slag process is reduced by about 29.45 %,which means the new process can further reduce the consumption of materials and slag amount.And the dephosphorization rate improves with the increase of limestone adding batches.
