Abstract: 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 fumace steelmaking-concasting-continuous rolling(scrap- EAF)flow  sheet  and  hot  metal  +scrap-arc  fumace-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  kg_ce/t_stsel but its total energy consumption of flow sheet increased by  1/3.

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。
