硅酸铝耐火纤维是近十年迅速发展起来的一种新型节能材料,在国外已被广泛应用到各种工业炉上,代表了工业炉结构改革的趋向。传统的工业炉多采用耐火砖砌造,由于耐火砖容重大,导热系数高,造成炉体蓄热和散热损失较大,炉子热效率低。尤其对于周期式操作的工业炉,由于蓄热损失占很大比重,热效率低的问题就更为突出。与耐火砖相比,硅酸铝纤维容重小、导热系数低、耐高温(国内生产的产品可在1000℃以下长期使用)、抗热震、筑炉简便迅速且易于维修。近年来由于工艺的改进,使纤维质量有了很大提高,成本不
Aluminosilicate refractory fiber is a new type of energy-saving material developed rapidly in recent ten years and has been widely applied to various industrial furnaces in foreign countries, which represents the trend of industrial furnace structural reform. Traditional industrial furnaces are mostly made of refractory bricks. Due to the large volume of refractory bricks and the high thermal conductivity, large losses of thermal storage and heat loss of the furnace body are caused, and the thermal efficiency of the furnace is low. Especially for the periodic operation of industrial furnaces, heat storage losses account for a large proportion, the problem of low thermal efficiency is even more prominent. Compared with refractory bricks, aluminum silicate fiber has low bulk density, low thermal conductivity and high temperature resistance (domestically produced products can be used for a long time under 1000 ℃), thermal shock resistance, easy and rapid furnace building and maintenance. In recent years due to the improvement of technology, the fiber quality has been greatly improved, the cost is not
