中文摘要: 对于目前艾萨冶炼过程中经常遇到的铜精矿原料中MgO含量偏高的现象，通过合成渣实验以及FactSage软件模拟对FeO-SiO2-CaO-MgO四元渣系中MgO含量对炉渣熔点的影响规律进行探究，结论得出：MgO在渣中的含量每增加0.5个百分点，炉渣熔点升高9~10℃；MgO含量从1%增加到5%，渣液相面积从10.75%减小到8.84%；MgO含量为2~2.5%时，优化渣型：Fe 36~38%；SiO2 28~30%；Fe3O4 8.6%；CaO 3.5%~4%。
Abstract:For the phenomenon that the MgO content in the copper concentrate raw materials often encountered in the current smelting process of Isa smelting, the MgO content in the FeO-SiO2-CaO-MgO quaternary slag system is simulated by the synthetic slag experiment and FactSage software. The law of influence is explored. The conclusion is that the content of MgO increases by 0.5% in slag, the melting point of slag increases by 9~10 °C, the content of MgO increases from 1% to 5%, and the liquid area of slag decreases from 10.75%. 8.84%; when the MgO content is 2~2.5%, the optimized slag type: Fe 36~38%; SiO2 28~30%; Fe3O4 8.6%; CaO 3.5~4%.
