目前,我国的各种热处理炉内衬还是采用耐火砖砌制,与世界先进工业国已广泛采用硅酸铝耐火纤维作炉衬相比,落后了将近四十年。据美国一九七四年报道,采用耐火纤维作炉衬的大型热处理炉可节约燃料33%,小型热处理炉可节约40%,连续式退火炉、罩式退火炉可节约10%;用于热处理电炉,可大幅度节约用电,安装功率可比砖砌炉小30～39%。英国在加热炉、退火炉、淬火炉等方面已普遍采用各种耐火纤维炉衬,可节约燃料26%,
At present, our country’s various heat treatment furnace lining or refractory bricks, and the world’s most advanced industrial countries have been widely used aluminum silicate refractory fiber lining, compared to nearly 40 years behind. According to the report of the United States in 1974, a large-scale heat treatment furnace using refractory fiber as a lining can save 33% of fuel, a small heat treatment furnace can save 40%, and a continuous annealing furnace and a bell annealer can save 10% , Can greatly save electricity, installation of power can be 30 ~ 39% smaller brick brick. Britain in the furnace, annealing furnace, quenching furnace, etc. have been widely used in a variety of refractory fiber lining, can save 26% of fuel,
