我厂自一九七九年开始,曾将厚10mm硅酸铝耐火纤维毡贴于箱式电阻加热炉炉膛内壁进行电炉改造,在电阻加热炉升温阶段可节电30%～60%,大大地提高了劳动生产效率。但是,通过一年多的生产实践,我们发现这种贴10mm 硅酸铝耐火纤维的方法还存在着一些问题。如寿命较短,使用半年以上易发生龟状裂纹,炉顶部分粘贴的纤维毡使用一年以上极易脱落;保温阶段无节电 I plant since 1979, had thick 10mm aluminum silicate refractory fiber felt attached to the inner wall of the box resistance furnace furnace transformation, in the resistance furnace heating phase can save 30% to 60%, greatly Improve labor productivity. However, after more than a year of production practice, we found that there are still some problems with this method of applying 10 mm aluminosilicate refractory fibers. Such as shorter life expectancy, the use of more than six months prone to turtle-shaped cracks, the top part of the fiber paste pasting more than one year easy to fall off; insulation phase without saving
