我厂用于熔炼Hp-1黄铜的有芯工频感应炉,在浇注完毕后进行保温时,因突然停电2.5小时,造成炉子“冻死”,无法继续熔炼,炉衬不得不报废,重新进行打结,给生产带来不应有的损失。经拆开炉衬进行检查和分析,发现炉子“冻死”是因熔沟内铜水凝固将感应槽拉裂所致。我们知道,有芯工频感应熔炼炉是按变压器的工作原理进行设计的。当 I plant used to smelt Hp-1 brass core frequency induction furnace, after pouring insulation, due to a sudden power outage for 2.5 hours, resulting in furnace “frozen dead”, can not continue melting, lining had to scrapped, re-proceed Knotted, to bring undue losses to the production. After the inspection and analysis of the opened lining, it was found that the “freezing death” of the furnace was caused by the crack of the sensing groove due to the solidification of the copper water in the melting groove. We know that core frequency induction melting furnace is designed according to the working principle of the transformer. when
