摘　　要：通过分析带渣吹炼单烟道(A型)、甩渣吹炼单烟道(B型)、带渣吹炼双烟道(C型)、甩渣吹炼双烟道(D型)等4种炉型的特点,将闪速连续炼铜过程视为由相对独立的闪速造锍熔炼过程和连续吹炼造铜过程构成,分别建立了闪速造锍熔炼多相平衡数学模型和连续吹炼造铜局域平衡数学模型,并通过中间物料的传递将2模型有机结合,从而构建了完整的闪速连续炼铜过程热力学模型.运用此模型,考察了炉型结构对闪速连续炼铜过程的粗铜生成热力学条件、Fe3O4行为、渣含铜及熔炼直收率的影响.结果表明,D型炉是比较理想的连续炼铜炉体;对于闪速连续炼铜,造锍熔炼段和铜锍吹炼段宜在相对独立的分区进行,各自烟气也应分开排出炉体.According to the common feature of flmr kinds of furnaces, including type A furnace with single flue but no slag partition wall, type B furnace with single flue and a slag partition wall, type C furnace with double flues but no slag partition wall and type D furnace with double flues and a slag partition wall, the copper flash continuous smelting furnace was considered as a synthesis reactor of two relatively independent processes： flash matte smelting process （FMSP） and copper continuous converting process （CCCP）, amt then the ther- modynamic model of the copper flash continuous smelting process was developed by establishing the muhi- phase equilibrium nmdel of FMSP and the local-equilibrium model of CCCP and combining them through the smelting intermediate product. Based on the thermodynamic model, the influences of the furnace structures were investigated on the thermodynamic formation condition of blister copper, the Fe304 behavior, the copper content in slag and the recovery rate of copper. Results show that the type D furnace is an ideal reaclor for copper flash continuous smelting, and hence, it＇s effective to keep the FMSP and the CCCP in relatively in- dependent partitions and to make their gases discharge out of the furnace from respective flues.
