%X 本文介绍了鄂钢低铁钢比生产工艺实施过程&#65292;通过应用铁水一罐到底、废钢、合金烘烤预热、铁水罐、钢包加盖等工艺技术&#65292;有效解决了低铁钢比生产造成的转炉冶炼热量不足问题&#65307;采取铁水罐加废钢、优化桶装废钢料型结构、转炉后加废钢、精炼炉加废钢等多渠道加废钢技术有效解决了大量废钢加入转炉困难的问题。实践表明实施低铁钢比生产技术后&#65292;转炉冶炼热量平衡&#65292;入转炉废钢量大幅提升&#65292;铁钢比指标由915 kg/t下降至757 kg/t&#65292;取得了节能降碳、提高生产效率的成果。<br>This paper introduces the implementation process of the low hot metal-to-steel ratio production technology at Echeng Iron & Steel Co., Ltd. by adopting process technologies such as hot metal charging via single ladle, scrap steel and alloy preheating, ladle covering for hot metal and steel ladles, the issue of insufficient heat in converter smelting caused by low hot metal-to-steel ratio production was effectively resolved. Multiple scrap charging methods including adding scrap to hot metal ladles, optimizing scrap material types in charging buckets, post-converter scrap addition, and scrap addition in refining furnaces successfully addressed the difficulty of feeding large quantities of scrap into converters. Practice demonstrates that after implementing the low hot metal-to-steel ratio technology, the converter smelting achieved thermal balance with significantly increased scrap input. The hot metal-to-steel ratio decreased from 915 kg/t to 757 kg/t, achieving results in energy conservation, carbon reduction, and production efficiency improvement.
