优化脱氧工艺改善低碳低硅钢钢水可浇性
介绍了重庆钢铁股份有限公司炼钢厂生产低碳低硅钢的脱氧工艺,对连铸过程中水口结瘤的原因进行分析,并提出了优化措施。生产实践表明:钢水中的活性氧质量分数控制在10×10-6～30×10-6时,单中包浇铸炉数由6～7炉提高到11～12炉,同时能保证连铸顺行和减少铸坯气孔。 The deoxidation process of low-carbon and low-silicon steel in steel plant of Chongqing Steel was introduced.The nuzzle clogging was analyzed and some measures were put forward.Production experiments showed that when the active oxygen was controlled between 10×10-6～30×10-6,the amount of furnaces would rise from 6～7 to 11～12,which will make the casting process work well and reduce casting holes.
