摘 要:结合不同钢种精炼造渣特点和钢水进精炼期间不同的生产条件,以普碳低合金钢HRB400E系列、优质碳素高碳钢65#系列以及板坯普碳钢Q235B系列为例进行研究,在原先精炼造渣的基础上进一步实施精炼钢水顶渣造渣分级管控,通过对不同钢种、不同硫含量等条件下精炼造渣分级管控措施的落实,实现精炼造渣效率有效提升、钢材质量稳步提高、精炼系统成本有效降低,进一步推动炼钢系统精细化管理向好、向深发展。Combined with the characteristics of refining slag making of different kinds of steel and different production conditions during the refining of molten steel,this paper focuses on the research of general low alloy steel HRB400E series,high quality carbon high carbon steel 65#series and slab general carbon steel Q235B series.On the basis of the original refining slag making,the slag making classification control of refined molten steel top slag is further implemented.Through the implementation of refining slag-making classification control measures under different steel grades and different sulfur content,the efficiency of refining slag-making is effectively improved,the quality of steel is steadily improved,the cost of refining system is effectively reduced,and the fine management of steelmaking system is further promoted to a better and deeper development.
