摘　　要：依据物料的不同,可以将回转窑分为石灰回转窑及水泥窑等,回转窑主要应用于冶金行业,比如冶金冶炼及煅烧氧化镁等。回转窑的工艺流程:将石灰石进行筛分处理,把合格的石灰石筛选出来,之后放入料仓里,再用料车运输至料仓的顶部,最后通过料管,将石灰石平均输送至每个预热室内。文章对活性石灰回转窑耐材的损坏原因进行了分析,对活性石灰回转窑耐材的控制进行了探讨,希望能帮助到有关人员。According to different materials,rotary kilns can be divided into lime rotary kilns and cement kilns.Rotary kilns are mainly used in metallurgical industry,such as metallurgical smelting and calcining magnesium oxide.Process flow of rotary kiln is that the limestone shall be screened,the qualified limestone shall be screened out,put into the silo,then transported to the top of the silo by the hopper truck and finally the limestone shall be evenly transported to each preheating chamber through the material pipe.This paper analyzes the causes of damage of refractory in the active lime rotary kiln and probes into control of the refractory in the active lime rotary kiln,hoping to help the relevant personnel.
