硅酸铝耐火纤维是一种新型的耐火保温材料。国外在七十年代就广泛应用起来。我国是在七十年代末才引起重视,开始在热处理设备上推广使用。硅酸铝耐火纤维材料具有良好的耐高温性能,可在1000℃条件下长时使用;它的比热小;它在500～1200℃条件下的导热系数为0.1～0.22千卡/小时·℃·米,为一般轻质耐火材料的1/3;它还具有容重小(为轻质耐火材料的1/5～1/(15))等特点。在热处理加热设备上使用该材料可以大大减小热损失,
Aluminosilicate refractory fiber is a new type of refractory insulation material. Abroad in the seventies is widely used. Our country did not pay much attention until the late seventies, and began to promote the use of heat treatment equipment. Aluminum silicate refractory fiber material has good high temperature performance, long-term use at 1000 ℃ conditions; it’s small specific heat; it under the conditions of 500 ~ 1200 ℃ thermal conductivity of 0.1 ~ 0.22 kcal / h ℃ · It is 1/3 of that of general lightweight refractory materials. It also has the characteristics of small weight (1/5 ~ 1 / (15)) for lightweight refractory materials. The use of this material on heat-treating heating equipment can greatly reduce heat loss,
