中温箱式电炉采用高强度超轻质耐火砖或硅酸铝耐火纤细毡炉衬来改造,已显示出节能效果,这已被大家所公认。如何再提高节能效果,我们根据资料介绍采取提高额定功率的办法,取得了一定的节电效果。一、试验与数据 1.试验条件: 两合相同的RJJ-45-9炉子,都进行过相同的耐火纤维毡炉衬改造。一台保留原配电阻丝(额定功率45千瓦),另一台改用φ4毫米的OCr25A15电阻丝,额定功率54千瓦。试验时两台炉子同时投入生产,按当天的设备操作记录
Medium-temperature box-type electric furnace using high-strength ultra-light refractory brick or alumina refractory soot lining to transform, has shown energy-saving effect, which has been recognized by all. How to improve the energy-saving effect, we introduced according to the information to improve the rated power approach, and achieved some energy-saving effect. First, the test and data 1. Test conditions: RJJ-45-9 furnaces of the same two, have carried out the same refractory fiber felt lining transformation. One to retain the original resistance wire (rated power of 45 kilowatts), the other switch to φ4 mm OCr25A15 resistance wire, rated at 54 kW. Two furnaces were put into production at the same time during the test, according to the equipment operation records of the day
