摘　　要：通过对低热水泥熟料岩相结构观察,分析了低热水泥熟料岩相结构特征;介绍了低热水泥的配料率值,即低KH、p值和高n值;分析了熟料煅烧环节参数的调整,需要减少喂料量,减少分解炉用煤比例,提高回转窑用煤比例,降低分解炉出口温度,为了适应高n值配料和生产高活性C 2S,回转窑内应保持高温煅烧。煅烧低热水泥熟料的热耗比煅烧普通水泥热耗略高。煅烧低热水泥熟料应防止出现还原气氛。Through the observation of the lithofacies structure of low-heat cement clinker,the lithofacies structure characteristics of low-heat cement clinker is analyzed,and the batching ratio value of low heat cement,namely,low KH,p value and high n value is introduced and the parameter adjustment of clinker calcining process is analyzed and feed quantity needs to be reduced and the proportion of coal used in the decomposing furnace is reduced,and the proportion of coal used in rotary kilns is increased,and the outlet temperature of the decomposing furnace is reduced.In order to adapt to high n value and produce highly reactive C 2S,high-temperature calcination should be maintained in rotary kiln.The heat consumption of calcined low-heat cement clinker is slightly higher than that of calcined ordinary cement.Reducing atmosphere should be prevented for calcined low-heat cement clinker.
