利用硅酸铝耐火纤维毡做箱式热处理炉内衬,节电效果较明显。但硅酸铝纤维毡与炉内壁的连接是个问题:采用T型钉来钉,比较麻烦,而且长期在高温下有掉落现象;有的用价格较贵的高溫粘结剂,不但成本高,而且货源不足。我们试验采用了水玻璃和耐火泥按1.25比1的简易高温粘结剂,方法简单易行,成本低,粘结效果 The use of aluminum silicate refractory fiber felt box heat treatment furnace lining, energy-saving effect is more obvious. However, the connection between the aluminum silicate fiber mat and the inner wall of the furnace is a problem: the use of T-shaped nails to nail, more troublesome, and long-term phenomenon of falling at high temperatures; and some with the more expensive high temperature binder, not only high cost, And lack of supply. We test the use of water glass and refractory mud by a simple high-temperature adhesive 1.25 to 1, the method is simple, low cost, bonding effect
