摘　　要：对高炉渣的排锌能力进行了研究,研究结果证明,渣中ZnO的还原属一级反应,反应的活化能为176kJ/mol～332kJ/mol,反应处于扩散范围。高碱度炉渣和高炉温不利于炉渣的排锌。含锌炉渣(ZnO=0.5～2.5％)的粘度不高,在一般温度(1400℃左右)下可保持良好的流动性。The ability to drain Zinc from BF slag were invetsigated in the laboratory scale. The following results are obtained. The reduction of ZnO in slag is one-level reaction. The activation energy of the reaction is 176～332kJ/mol, and this reaction is controlled by diffusion. High basic and high hearth temperature are infavourable to drain zinc from BF slag. Slags with 0.5～2.5%ZNO have good fluidity at 1400℃.
