降低电炉渣含铜研究

Study on Reduction of Copper Loss in Slag from Electric Furnace

通过物相分析结果,研究了电炉渣含铜损失的主要形态,并根据金隆历年生产数据及理论分析影响渣含铜的主要因素,着重研究Fe3O4和Fe/SiO2对渣含铜的影响。并在此基础上通过数值仿真及国内外厂家生产经验,提出了氧势梯度熔炼生产技术及一系列有利于降低渣含铜的生产控制方式。

By analyzing the results of phase, copper loss in slag from electric furnace is studied in Jinlong. Particularly the effect of Fe3O4 content in slag and Fe/SiO2 on copper loss is investigated on the basis of operational data in Jinlong in the past years. Combined with numerical simulation and operational experience in Smelters inside and outside China, An operational style called Oxy-potential Grads Smelting process and the controlling methods of reducing copper loss are put forward.
