我厂有一台RIX—75—9电炉(参考天津电炉厂图纸自制)已使用三年,炉子砖体及电热丝已自然损坏,列入1980年大修计划。该炉若采用贴耐火纤维(平贴或立贴)不适宜,因炉体耐火砖已损坏,重砌后再贴,势必增加修炉成本,并且由于受粘贴厚度限制,也不可能达到高的节电效果。为此我厂采用硅酸铝耐火纤维作内壁,用价格便宜的矿渣棉作背层的复合炉衬,来改造该炉。经一年的生产使用证明,情况良好。一、炉子改造前后的情况
I plant a RIX-75-9 electric furnace (reference Tianjin Electric furnace plant drawings made) has been used for three years, the furnace tile and electric wire has been naturally damaged, included in the 1980 overhaul plan. The furnace if the use of refractory fiber paste (flat or vertical stickers) is not appropriate, because the furnace refractory bricks have been damaged, re-paste and then paste, is bound to increase repair costs, and due to the thickness of the paste, it is impossible to achieve high Power saving effect. To this end I plant aluminum silicate refractory fiber for the wall, with cheap slag wool for the back of the composite lining, to transform the furnace. After a year of production and use of proof, in good condition. First, before and after the transformation of the stove
