我厂55米~3高炉平均日产生铁180吨以上,最高可达220吨,每班出铁5～6次。由于出铁次数频繁。撇渣器的安全长寿成为炉前生产中的重要环节。原来用高铝砖砌筑或炭素—粘土捣打的撇渣器寿命一般不超过500次,通过的铁水量不足6000吨。而且这种撇渣器很不安全,曾两次发生严重溃裂事故,使大量铁水和熔渣横溢,烧坏了铸铁机及其操作平台,炸毁了冲渣沟,每次休风5～6小时,造成了严
I plant an average of 55 m ~ 3 blast furnace iron 180 tons or more, up to 220 tons, each shift 5 to 6 times. Due to the frequency of the frequent. Skimmer safety and longevity become an important part of the furnace production. The original use of high-alumina brick masonry or carbon-clay ramming skimmer life is generally not more than 500 times, through less than 6,000 tons of hot metal. And this skimmer is very unsafe, there have been two serious rupture of the accident, so that a large number of molten iron and slag overflow, burned the cast iron machine and its operating platform, destroyed the slag ditches, each off 5 ~ 6 hours, resulting in strict
