摘　　要：针对熔析精炼炉处理热镀锌渣存在的加料过程熔析池大幅降温、B号锌含铁超标、尾气难以利用等问题,对熔析精炼炉进行改进,其结构更加合理,处理量大大增加,B号锌符合国标3号锌锭要求。This paper briefly introduces the problems encountered in the processing of hot-dip galvanizing slag with liquation refining furnace, such as substantial temperature reduction in liquation tank during the feeding process, iron content in B-zinc exceeding the limit and difficult utilization of tail gas. Some measures are taken to improve the liquation refining furnace to make its structure more reasonable, increase the processing capacity and decrease the impurity content in B-zinc so as to meet the national standard of 3# zinc ingot.
