分析4种闪速连续炼铜炉型的本质特性，提出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两模型有机结合，从而构建完整的闪速连续炼铜过程热力学模型。运用此模型，考察炉型结构对闪速连续炼铜过程的粗铜生成条件、Fe3O4行为、铜在渣中损失以及铜直收率等因素的影响。结果表明：相对于其他3种炉型，甩渣吹炼双烟道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，各自炉渣和烟气也应分开排出炉体。

According to the innate characteristic of four types of furnace, the copper flash continuous smelting (CFCS) furnace can be considered a synthetic reactor of two relatively independent processes: flash matte smelting process (FMSP) and copper continuous converting process (CCCP). Then, the CFCS thermodynamic model was proposed by establishing the multi-phase equilibrium model of FMSP and the local-equilibrium model of CCCP, respectively, and by combining them through the smelting intermediates. Subsequently, the influences of the furnace structures were investigated using the model on the formation of blister copper, the Fe3O4 behavior, the copper loss in slag and the copper recovery rate. The results show that the type D furnace, with double flues and a slag partition wall, is an ideal CFCS reactor compared with the other three types furnaces. For CFCS, it is effective to design a partition wall in the furnace to make FMSP and CCCP perform in two relatively independent zones, respectively, and to make smelting gas and converting gas discharge from respective flues.
