摘　　要：采用相似原理指导下的物理模拟试验,通过实时测定溶液电导率研究高效铜侧吹熔炼反应器内均混时间。结果表明,在喷嘴排布紧凑的1#排布下,熔池内流体的混合时间相对较短;随着喷嘴直径的增加,气体流速减小,均混时间变长;随着气体流量的增大,均混时间不断减小,但减小的幅度变小。Physical model experiments were carried out based on similitude principle to study mixing time in high efficient copper side-blown smelting reactor by measuring conductivity of solution. The results show that the mixing time is relatively short with No. 1 compact nozzle arrangement. Gas velocity drops and mixing time rises with increase of diameter of nozzles. Mixing time drops continuously with smaller amplitude with increase of gas flow.
