机械行业的热处理电炉素有“电老虎”之称,因此,开展电炉节能的研究十分重要。近年来,许多厂采用新型耐火、绝热保温材料作炉衬,对提高炉子的热效率和节约能源起到了一定作用。83年9月,我厂对RJX-60-9型箱式电阻炉进行了改造,使炉子空炉升温时间明显缩短,空载热损失显著下降,节能效果显著。一、炉衬材料性能分析1.炉膛耐火层采用 RQN-0.6a 或RQN-0.8a 新型砖砌筑。由于其导热系数比
Machinery industry heat treatment furnace known as “electricity tiger ”, therefore, to carry out the study of electric furnace energy conservation is very important. In recent years, many plants use new refractory and thermal insulating materials as linings, which play a role in improving the thermal efficiency and energy conservation of the furnace. In September 1983, our factory reformed the RJX-60-9 box-type resistance furnace, shortening the heating time of the furnace in an empty furnace, reducing the heat loss in no-load and remarkably saving energy. First, the lining material performance analysis 1. Furnace refractory layer using RQN-0.6a or RQN-0.8a new brick masonry. Because of its thermal conductivity ratio
