摘　　要：宣钢一钢轧厂为降低吨钢生产成本、提高钢材的力学性能、改善钢水质量,调整了低合金钢合金料优质廉价碳化硅的用量,替代成本较高的硅铁和部分增碳剂使用量。在炼钢作业区110 t转炉3#炉冶炼HRB400EZT1钢进行跟踪研究,结果表明:铸坯成分稳定可控,吨钢成本可降低0.88元/t,钢材的力学性能得到改善。新合金化方案完全可以取代传统方案,获得了良好的经济效益。In Xuan Steel,to reduce cost per ton of steel,improve mechanical property and quality of molten steel,the amount of alloy material： high- quality and low- cost Si C used in smelting of low- alloy steel is increased to substitute the high- cost ferrosilicon and part of recarburization agent. The procedure of smelting HRB400EZT1 steel with 110- ton converter 3# is traced and researched. It is showed that the composition of casting billet is steady and can be controlled,the cost per ton of steel reduced by 0. 88 yuan / t,the mechanical property of steels improved. The newalloying plan can replaced the traditional one,good economic profit got.
