摘要
针对攀钢钢水条件不满足RH设备处理要求及外方技术文件不易修改的具体情况,适时调整了技术路线,采取出钢预脱氧,处理前期增碳,调整[C]与[O]的比例关系等措施使钢水条件达到处理要求;设计、制定的增碳计算公式达到了较高的终点命中率,实用有效。采用改进后的轻处理工艺,终点[C]合格率大于90%,[Als]合格率大于95%,残余[O]控制在30×10-6～70×10-6,深冲钢内在质量受到用户的广泛好评。
RH light treatment are used for some heats of molten steel refining at PZH Steel. According to the situation of molten steel and RH equipment, the refining practice includes pre-deoxidizing in steel tapping, carbonizing and adjusting the [C]/[O] ratio. An empirical formula was set up for carbonizing, and the practice proved it is effective. The hitting accuracy of RH light treatment is relative high, the final [C] qualification rate exceeds 90%, the final [C] qualification rate exceeds 95%, and the [O] is 30×10^(-6)～70×10^(-6). The internal quality of deep-drawing steel after RH light treatment is satisfying.
