摘　　要：通过收集生产数据和钢材性能指标,对硬线钢夹杂物的成分、形貌、平均粒径大小和夹杂物数量的变化进行分析。结果表明,硬线钢C类夹杂物检验合格率的影响因素有转炉下渣、精炼炉软吹、耐火材料质量、钢包自开率和结晶器液面波动等。提出了生产工艺优化措施。采取措施后,硬线钢C类夹杂物检验平均合格率由98.99%提高到99.39%。To analyze composition,morphology,average particle size and quantity of inclusions in hard wire steel by collecting a large number of production data and steel performance indexes.Results show that factors affecting qualification rate of C-type inclusions in hard wire steel include converter slag,refining furnace soft blowing,refractory quality,ladle self opening rate and mold liquid level fluctuation.The optimization measures of production process are put forward.After taking measures,the average qualified rate of C-type inclusions in hard wire steel was increased from 98.99% to 99.39%.
