自从世界能源危机以来,节能型炉衬—耐火纤维(及其制品)便开始在各种工业窑炉上得到应用。耐火纤维是一种容重小、导热系数小、使用温度高的节能材料。国内七十年代开始陆续研制和使用,可大量节约电耗,并大幅度降低外罩重量。根据资料,用耐火纤维改造炉衬可节约燃料或电耗10～40％。 罩式炉是钢材热处理炉的典型,它工作时要耗费大量的热能用于炉衬的升温和保
Since the world energy crisis, energy-saving linings - refractory fibers (and their products) have been used in a variety of industrial furnaces. Refractory fiber is a small capacity, low thermal conductivity, the use of high temperature energy-saving materials. The domestic seventies began to develop and use, can save a lot of power consumption, and significantly reduce the cover weight. According to the information, using refractory fiber to transform the lining can save fuel or power consumption 10 ~ 40%. Hood furnace is a typical steel heat treatment furnace, which work to spend a lot of heat for the lining of the heating and maintenance
