通过生产试验数据,研究转炉炼钢用石灰石代替部分石灰造渣过程中石灰石的行为,论证了转炉采用石灰石造渣炼钢的相对合理方案。阐述了石灰石应用于转炉炼钢的优越性,既可以部分替代活性石灰,同时还可以平衡转炉富余热量,减少其他降温材料的使用量,为炼钢生产节约了成本,创造了更大的利润空间。 Through the production of test data, the limestone in BOF was studied to replace the limestone in the process of slagging, and the reasonable scheme of converter using limestone slagging was demonstrated. The advantages of limestone used in converter steelmaking are expounded, which can not only partially replace activated lime, but also balance the surplus heat of converter, reduce the usage of other cooling materials, save the cost for steelmaking and create more profit margin .
