摘要
针对河钢唐钢不锈钢公司高炉铁水成分特点,以及现在转炉自动炼钢系统存在的问题,开展了自动炼钢模型的优化及二次开发。通过渣碱度控制,终点温度高低温切换、碳温动态控制等工艺模型的优化和超低硫、磷钢种标准补吹模型二次开发,吹炼终点碳温双命中率达90%以上,转炉补吹比例<3%,硫磷含量<0.01%,实现了降低石灰等造渣料消耗、提高终点温度命中率及完成超低硫磷钢种冶炼的目的。
In view of the characteristics of hot metal composition of blast furnace in HBIS Tangshan Stainless Steel Company and the existing problems of the converter automatic steelmaking system,the optimization and secondary development of automatic steelmaking model were carried out.Through the process model optimization such as slag basicity control,high and low temperature switching of terminal temperature,dynamic control of carbon temperature,and secondary development of standard supplementary blowing model for ultra-low sulfur and phosphorus steel grades,the double hit rate of carbon temperature at blowing end point is more than 90%,the supplementary blowing proportion of converter is less than 3%,and the sulfur and phosphorus content is less than 0.01%.The purpose of reducing the slagging materials consumption such as lime,increasing the hit rate of end point temperature and completing the smelting of ultra-low sulfur and phosphorus steel grades has been realized.
