利用已开发的伴生元素在铜熔炼过程中分配行为的计算机模型,对霍恩冶炼厂诺兰达炉造冰铜过程进行了计算机模拟,其预测结果与该厂1990年的实际生产数据一致性很好。并引入MNagamori的悬浮指数方程对渣中铜和硫的机械夹杂损失进行了计算,探讨了铜机械损失的形态,认为铜在渣中机械夹杂的部分主要是以硫化物形态存在。同时,对诺兰达炉中氧位、冰铜品位、渣中Fe3O4及渣中铜溶解损失和机械损失等进行了计算机模拟,分析了氧分压、冰铜品位、渣中Fe3O4对渣中铜溶解损失和机械损失的影响,并讨论了其分析结果对生产实践的指导意义。
Using the computer model of the distribution of the associated elements in the copper melting process, the computer simulation of the Noblet furnace ice making and copper fabrication at the Horn smelter was carried out. The predictions are in good agreement with the actual production data of the plant in 1990 it is good. The mechanical entrainment loss of copper and sulfur in the slag was calculated by introducing the suspension index equation of MNagamori. The mechanical loss of copper was discussed. The mechanical inclusion of copper in the slag mainly existed in the form of sulfide. In the meantime, the numerical simulation of oxygen level, matte grade, Fe3O4 in slag and copper dissolution loss and mechanical loss of slag in Nolander furnace was carried out. The effects of oxygen partial pressure, matte grade, slag Fe3O4 on slag copper Dissolution loss and mechanical loss, and discussed the guiding significance of the analysis results to the production practice.
