硅酸铝耐火纤维和高强度超轻质耐火砖是理想的新型节能保温材料。在热处理炉中,用它们取代传统耐火材料做炉衬,可以取得显著节能效果。选择节能耐火材料和保温材料,合理确定炉衬结构型式和厚度,是提高热处理炉效率的关键。本文根据热量损失计算和生产应用实测数据,对不同炉衬结构的节能效果进行了分析和比较,为合理选择和使用新型节能材料提供参考。一、X-75箱式电炉的热平衡测试 X-75箱式电炉总重量约7140kg,炉衬是用比重1.3～2.2g/cm~3的轻质和重质耐火
Aluminum silicate refractory fiber and high strength ultra-light refractory brick is the ideal new energy-saving insulation material. In the heat treatment furnace, use them instead of the traditional refractory lining, can achieve significant energy savings. Select energy-saving refractory materials and insulation materials, a reasonable determination of lining structure type and thickness, is to improve the efficiency of heat treatment furnace key. Based on the calculation of heat loss and the actual data of production application, this paper analyzes and compares the energy-saving effects of different lining structures and provides reference for choosing and using new energy-saving materials reasonably. First, the X-75 box-type electric furnace heat balance test X-75 box-type electric furnace total weight of about 7140kg, the lining is the proportion of 1.3 ~ 2.2g / cm ~ 3 light and heavy refractory
