为了解决箱式电炉结构性能落后、耗能高、效率低、精度差、炉温均匀性达不到部颁标准的问题,520厂对30kW箱式电炉进行了改造。改造的方案是,炉体两侧,后墙增加两层40mm厚硅酸铝纤维棉,炉门、炉顶、炉底也填充 In order to solve the structural performance of the box-type electric furnace behind, high energy consumption, low efficiency, poor accuracy, uniformity of the furnace temperature reach the ministerial standards, 520 factory 30kW box-type electric furnace was transformed. Transformation of the program is, both sides of the furnace, the back wall to add two layers of 40mm thick aluminum silicate cotton, furnace doors, roof, bottom are also filled
