用自由焓最小法计算了白银熔池熔炼反应平衡时各相的组成，引入物理悬浮修正公式．估算不同冰铜品位时两相的悬浮夹杂率，对平衡计算结果进行修正．计算值与实际生产数据的比较表明，白银熔池熔炼体系达到或接近平衡状态．计算了富氧熔炼时风料比和氧料比对各相组成的影响，结果表明：决定冰铜品位的主要因素是氧料比。氧料比增加时，冰铜品位提高，气相中SO2浓度增加，但渣中Fe3O4浓度增加，由悬浮夹杂造成渣中铜损失增加．
The free-enthalpy minimum method was used to calculate the composition of the phases in the equilibrium reaction of the silver pool melting reaction, and the physical suspension correction formula was introduced. The two-phase suspension inclusion rate was estimated at different matte grades, and the balance calculation results were corrected. Comparisons between the calculated values and the actual production data show that the silver bath melting system reaches or approaches equilibrium. The effects of the ratio of air to material and the ratio of oxygen to oxygen on the phase composition were calculated. The results show that the main factor that determines the matte grade is the oxygen to material ratio. When the oxygen ratio increases, the matte grade increases and the SO2 concentration in the gas phase increases, but the concentration of Fe3O4 in the slag increases and the copper loss in the slag increases due to suspension inclusions.
