高碳磨球钢生产工艺实践

Process practice on high carbon grinding ball steel

对高碳磨球钢的生产工艺技术进行试验研究,采用转炉→LF→RH→连铸→收集→缓冷→加热→水除磷→开坯→连轧的生产工艺路线制造高碳磨球钢,成品质量检测结果表明:钢中化学成分控制准确,碳偏析、低倍组织等其他相应技术指标均满足要求,非金属夹杂物相对比较细小。

For experimental research on the production technology of high carbon grinding ball steel,the metallurgical technology process of B2 Ggrinding ball steel is comprised of converter,LF,RH,continuous casting,collection,slow-cooling,heating,phosphorus removal of water,cogging and continuous rolling.The test result of the control of chemical composition in steel is accurate,carbon segregation,macrostructure and other corresponding process indexes meet the requirements,and non-metallic inclusions are relatively small.
