我厂1800千伏安75％硅铁电炉经常因故热停。当停炉时间较长时,炉内存料凝为一体。重新开炉的传统处理方法,一是扒渣法,二是洗炉法。这两种方法都有时间长、成本高,电耗高等缺点。我们根据我厂的生产实际情况,摸索出了一个冷开炉法。1.送电前准备清除各相电极头部的粘料和电板下面的冷结炉料。用木柴烘烤电极1～2小时,以 Our factory 1800 KVA 75% ferrosilicon furnace often for some reason heat stop. When the shutdown time is longer, the furnace material condensate as one. The traditional method of re-open furnace, first slag law, the second is the method of washing furnace. Both of these methods have the disadvantages of long time, high cost and high power consumption. According to the actual production of our factory, we found out a cold-open furnace method. 1. Prepare to remove the power supply before the head of each phase of the sticky material and electrical panels below the cold junction charge. Bake the wood with firewood for 1 to 2 hours
