提出采用炼钢污泥、石英砂、锰矿按一定比例混合制成半钢炼钢用造渣剂的方法,并通过工业试验验证了新型造渣剂用于转炉炼钢造渣的可行性,实现了炼钢污泥的循环利用。工业试验表明,与原复合造渣剂相比,新型造渣剂具有更好的冶金效果。新型造渣剂初期渣形成时间缩短0.5min,脱磷率平均提高1.2%,终点钢水残锰质量分数平均提高0.01%,终点炉渣T.Fe质量分数平均降低0.55%,炉渣物相组成满足溅渣护炉的要求,循环利用具有良好的溅渣护炉效果。
The method of mixing slagging steel, quartz sand and manganese ore into slagging agent for semi-steelmaking was proposed, and the feasibility of using the new slagging agent for BOF slagmaking was verified through industrial experiments. Steel recycling of sludge. Industrial tests show that the new slagging agent has a better metallurgical effect than the original composite slagging agent. The initial slag formation time of the new slag-forming agent shortened by 0.5 min, the dephosphorization rate increased by 1.2% on average, the mass fraction of residual manganese in the final molten steel increased by 0.01% on average, and the average mass fraction of T.Fe in the final slag decreased by 0.55% Protection of the furnace requirements, recycling has a good slag splashing effect.
