摘要
通过对炼钢生产数据的统计分析,研究了转炉终点残锰含量及锰收得率的影响因素。研究表明,影响转炉终点残锰含量和锰收得率最主要的因素是转炉终点碳含量和铁水初始硅含量。在高拉碳操作下,钢水碳含量对锰的还原起主导作用,此时转炉终渣FeO含量和终点钢水温度对锰收得率的影响并不十分明显。
The factors affecting the end-point residual content of manganese and its yield rate in the converter process has been researched on the basis of the statistic analysis of the steelmaking production data. Results show that the end point carbon content of converter process and initial silicon content of hot-metal are the key factors affecting the end-point residual content of manganese and its yield rate. Under the condition of catch- ing carbon operation, the carbon content of molten steel plays a leading role for reduc- tion of the manganese oxide. At this juncture the effect of end point FeO content of slag and end point molten steel temperature of converter on the yield of manganese are not so apparent.
