首钢京唐公司炼钢工序设计采用“全三脱”冶炼模式炼钢,重型废钢在脱磷炉不能熔化,中型废钢和统料废钢存在入炉困难、转炉终点增硫现象和金属收得率低的问题。为此特组织试用破碎废钢,结果既满足了脱磷炉熔化的问题,又解决了入炉困难、增硫问题和金属收得率低的问题。 Shougang Jingtang company steelmaking process design using “full three off ” smelting mode of steelmaking, heavy scrap can not be melted in the dephosphorization furnace, the existence of medium-sized scrap and scrap material into the furnace difficult, the end of the converter sulfur phenomenon and metal income Low rate of the problem. This special organization for the trial crushing scrap, the results not only to meet the melting furnace dephosphorization problems, but also solve the furnace into the furnace, sulfur problems and the problem of low metal yield.
