摘　　要：文中通过实验室试验和生产现场试验,验证了低碳低磷钢炉渣改质的方法。使用炉渣调整剂对炉渣改质时,应选用含碳量高的炉渣调整剂。实验室试验使用碎焦粒对炉渣改质,取加入焦粒4 min时的渣样分析可知,在溅渣时间内可降低炉渣(FeO)5%左右。现场加碎焦粒对炉渣改质试验,成本降低50%,同时降低渣中(FeO)比使用炉渣调整剂高1%,证明该方法有效可行。在实际使用过程中应根据渣量、终渣情况、焦粒成分等适当调整。Through laboratory tests and production field tests,the slag modification method of low-carbon and low-phosphorus steel was verified in this paper.The slag regulator with high carbon content should be selected when the slag regulator is used to modify the slag.In the laboratory test,the crushed coke particles were used to modify the slag.When the coke particles have been added for 4 minutes,the analysis of slag samples showed that the slag(FeO)could be reduced by about 5% during the slag splashing time.In the on-site test,the coke particles were used to modify the slag.The results show that the cost was reduced by 50% and the reduction of FeO in the slag was 1% higher than that of slag regulator,which proved that the method was effective and feasible.To conclude,in actual use,it should be appropriately adjusted according to the amount of slag,final slag,coke particle composition and so on.
