摘　　要：通过建立转炉物料平衡、热平衡模型，分析了直接还原铁作为冷却剂替代废钢用于转炉炼钢对炼钢过程各经济技术指标的影响。通过对模型计算结果的分析，限制直接还原铁替代废钢量的主要因素为其SiO2和TFe的含量，通过将其控制在一定范围内，转炉炼钢使用100％直接还原铁代替废钢在技术上是可行的。Through setting up the mass and heat balance model, the influence of direct reduction iron （DRI） that is used as coolant instead of scraps on the BOF steelmaking procedure parameters is examined in this article. Based on the analysis on the result of the simulation model, it is found that the content of SiO2 and TFe in DRI is the main factor limiting DRI to replace scraps as coolant in BOF steelmaking procedure. Through controlling the content of SiO2 and TFe in DRI within a reasonable range, it is approved that DRI completely replacing scraps in BOF steelmaking procedure is available in aspect of technique.
