天津钢管集团股份有限公司150t电弧炉炼钢长期使用四元炉料,其平均炉料配入比为46.2%废钢、9.1%生铁、26.4%热铁水、18.3%DRI,通过物料衡算和能量衡算分析了电弧炉冶炼过程的物耗和能量状况.论文研究得出了单位炉料对物耗和能耗的影响,以及四元炉料结构变化对吨钢电功率输入的需求范围为153～744kW.对大量生产数据进行逐步回归分析,结果表明:直接还原铁配入比RDRI的影响最为显著,每增加1.0%,吨钢电耗大约增加1.4kWh;其次是铁水配入比RHM,其每增加1.0%,吨钢电耗大约降低2.0kWh.
Tianjin Steel Tube Group Co., Ltd. 150t EAF long-term use of four yuan charge, the average charge ratio of 46.2% scrap, 9.1% pig iron, hot metal 26.4%, 18.3% DRI, through the material balance and energy balance analysis The material consumption and energy status of electric arc furnace smelting process.The paper studied the impact of unit charge on material consumption and energy consumption and the demand range of quaternary charge structure for the input of electric power per ton of steel is 153 ~ 744kW.For a large number of production data Stepwise regression analysis showed that the effect of RDI was more significant than that of RDRI. For every 1.0% increase, the power consumption per ton of steel increased about 1.4kWh, followed by that of hot metal mixed with RHM, which increased 1.0% for each tonne of steel Approximately 2.0kWh reduction.
