摘　　要：文章探索了不同配比和温度的锌混合渣高温试验,发现在搭配硫酸钙渣和中和渣处理后,窑渣含锌量均有一定程度的增加,温度愈高,锌的还原速度愈快,窑渣中锌的含量越低;为减少锌金属的损失,应控制CaSO_(4)渣和中和渣与锌浸出渣的搭配比例小于1.6%。物料温度过高对窑内衬运行周期影响较大,窑内温度应保持在1100~1300℃范围内,保证回转窑的高效、经济、稳定运行。This research explored high-temperature experiments of zinc mixed slag with different ratios and temperatures,and found that after treatment with calcium sulfate slag and neutralization slag,the zinc content in kiln slag increases to a certain extent.To reduce the loss of zinc metal,the ratio of CaSO_(4)。slag and neutralization slag to zinc leaching slag should be controlled to be less than 1.6%.The higher the temperature,the faster the reduction rate of zinc,and the lower the zinc content in kiln slag.Excessive material temperature has a significant impact on the operating cycle of the kiln lining.The temperature inside the kiln should be maintained within the range of 1100~1300℃to ensure efficient,economical,and stable operation of the rotary kiln.
