热处理电阻炉的炉衬历来都是用砖体砌筑。由于砖体的容重,比热和导热系数大,因而导致热惰性大,热效率低,生产周期长,耗电量大。60年代初,各种耐火纤维的二次制品相继问世,其中被广泛采用的是硅酸铝耐火纤维,由于它具有耐高温、容重轻、比热小、导热系数小的优点以及有良好的电绝缘性能,特别适宜于制作热处理电阻炉,是电阴炉内衬比较理想的新型材料。一机部一院,二院
Heat treatment furnace resistance furnace lining has always been masonry. Due to the bulk density of brick body, large specific heat and thermal conductivity, it leads to large thermal inertia, low thermal efficiency, long production cycle and large power consumption. The early 60s, all kinds of refractory fiber secondary products have come out one after another, which is widely used is aluminum silicate refractory fiber, because of its high temperature, light weight, small heat, the advantages of small thermal conductivity and good electricity Insulation performance, especially suitable for the production of heat treatment furnace resistance, is the lining of the ideal new type of material.
