摘　　要：加热炉炉墙外表面温度较高,需要选用合理的衬里结构和耐火材料进行绝热处理。常规设计的衬里在使用过程中会出现因材料导热性能与设计的差别、材料老化、施工质量及结构不合理等问题,投用后大多会出现加热炉墙外壁超温、炉体漏风冒烟现象,散热损失的增加直接影响了加热炉能耗。新型耐火隔热材料的问世对改进衬里结构起到了积极的作用,尤其是复合衬里结构具有降低加热炉体漏风、降低炉外壁温以及减少散热损失的显著优点。The general furnace design specification need heat insulation process of ceiling structure selection and refractory lining, as heated furnace wall＇s surface temperature being higher. Afer general furnaces come to service ; most of ,furnaces appear outside wall of over-temperature furnace,furnace smoke leakage phenomenon,heat loss,and the impact of furnace energy consumption. Because of the thermal properties Of materials and design differences,the aging of materials, construction quality, structure irrational and so on, the increase of heat leakage effect heat furnace energy directly. Being of new type fire-resistant insulation materials available, it could reduce the furnace body wind leakage, furnace wall＇ s temperature, heat loss, especially recommended lined composite structure used.
