铅闪速熔炼过程的多相平衡模型
Multi-phase equilibrium model of lead flash smelting process
摘要
Abstract
Based on the principle of Gibbs free energy minimization, a thermodynamic model of the lead flash smelting equilibrium system, including crude lead, matte, slag and gas four phases, was built using element potential method. The equilibrium composition was calculated at the same burden composition, smelting temperature and oxygen enrichment through the semi-industrial test. The results show that the absolute error of the percent content of Pb in crude lead is 0.30, and its relative error is 0.30%; the absolute errors of the mass fraction of Pb, CaO and SiO2 in slag are 2.00, 0.S0 and 0.70 respectively, and the relative errors of them are 6.67%, 3.57% and 3.89%. It is proved that the model can wholly embody the lead flash smelting practice and can be applied to the thermodynamic research of the smelting process.关键词
