摘要
在物料平衡和热平衡模型的基础上,结合相关工艺参数,分别建立了废钢-电弧炉-连铸-连轧流程(废钢-电弧炉流程)和铁水+废钢-电弧炉-连铸-连轧流程(混合流程)的工序能耗的计算模型;分析了模型中几个重要参数对工序能耗的影响。结果表明,电弧炉热装铁水33％的混合流程的工序能耗较废钢-电弧炉的工序能耗降低43.72 kg_(标煤)/t_(铜),但流程总能耗约增加1/3。
Based on materials balance model and heat balance model and combined with relative process parameters, the calculated models for process energy consumption of scrap-arc furnace steelmaking-concasting-continuous rolling （ scrap- EAF） flow sheet and hot metal ＋ scrap-arc furnace-concasting-continuous rolling （ metal ＋ scrap-EAF） flow sheet have been established and the effect of several key parameters on process energy consumption is analyzed. Results showed that compared with scrap-EAF flow sheet the process energy consumption of 33% metal ＋ scrap-EAF increased by 43.72 kgce/tsteel but its total energy consumption of flow sheet increased by 1/3.
