摘要/Abstract

摘要： 基于现代电弧炉炼钢的工艺理论,建立了描述电弧炉炼钢过程的热化学计量模型和模型,应用该模型对大冶特钢的60 t直流电弧炉冶炼过程进行了模拟,对100%废钢、30%铁水+70%废钢,64.4%铁水+ 35.6%废钢的炉料结构条件下的电弧炉冶炼过程进行了能分析和㶲分析。结果表明,兑加铁水可明显降低冶炼电耗,但降低总能量利用率,如考虑回收利用炉气和冷却水物理,则电弧炉冶炼过程的利用率略有增加。

Abstract: Based on fundamental process theory for modern electric arc furnace steelmaking (EAF) , the thermo chemistry calculating model and exergitic model to describe EAF steelmaking process have been established, by which the simulation of steelmaking process for a 60 t DC EAF at Daye Special Steel was carried out to carry out the energy and exergy analysis on EAF steelmaking process with charge of 100% scrap, 30% hot metal + 70% scrap, and 64. 4% hot metal + 35. 6% scrap. Results show that the melting electric energy consumption decreases obviously by charging part hot metal, but total energy utilization ratio decreases, and as considering to recover and utilize waste gas and cooling water physical exergy, the exergy of EAF steelmaking process increases slightly.
