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。
The essential characteristics of four flash continuous copper smelting furnaces were analyzed. It was proposed that the flash continuous copper smelting process should be regarded as a relatively independent flash flash matte smelting process and a continuous blowing and blowing process, and flash flash matte smelting Multi-phase equilibrium mathematical model and continuous blowing copper local equilibrium mathematical model, and through the intermediate material transfer the two models are combined organically to build a complete flash-continuous copper thermodynamic model. By using this model, the effect of furnace structure on blister copper formation, Fe3O4 behavior, loss of copper in slag, and direct copper yield were investigated. The results show that, compared with the other three types of furnaces, the slag-blowing double-flue D-type furnace is an ideal continuous copper-making furnace body. For continuous copper smelting, the matte matte and matte matte should be heated at Relatively independent partition, the respective slag and flue gas should be separately discharged from the furnace.
