我厂铸造车间2.5t/h冲天炉的热风炉胆经技术改造后,使用寿命长达四年多,熔化炉次近400炉次,使用寿命比改造前大为提高。过去一个热风炉胆在溶化40～60炉次后,就得拆卸,更换,用不了一两年就得报废,由于炉胆结构复杂,制造、维修和更换都很麻烦,所以常因炉胆报废而影响正常的生产。 2.5t / h cupola furnace in our factory has the service life of more than four years after the technological transformation of the hot-blast furnace of the cupola. The melting furnace is nearly 400 times and the service life is much higher than before. In the past a hot air oven gall after melting 40 ~ 60 heats, you have to disassemble, replace, take less than a year or two have to scrap, due to the complex structure of the furnace, manufacturing, maintenance and replacement are very troublesome, so often scrapped due to furnace And affect the normal production.
