摘要
为探索转炉采用石灰石代替石灰造双渣脱磷工艺,对某钢厂100t吨转炉的石灰石双渣试验结果进行了研究,并对石灰石造渣脱磷的优势进行了理论分析。试验结果表明:试验炉次脱磷率平均为88.67%;对比石灰双渣工艺,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 t ton converter using limestone and double-slag in a steel plant are 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 meanss the new process can further reduce the consumption of materials and slag amount.dephosphorization rate improves with the increase of limestone adding batches,
