吉林铁合金厂6000千伏安真空电阻炉,用真空固态脱碳法生产微碳铬铁,原来采用罗茨真空泵机组作为真空抽气机组,由于被抽炉气含有比较大量的金属粉尘,虽然在除尘上采取了一些措施,但是没有彻底消除粉尘对泵组的影响,致使机械泵组经常损坏,维修量大,因此决定改用蒸汽喷射泵作为抽 Jilin Ferroalloy Plant 6000 KVA vacuum resistance furnace, vacuum solid state decarbonization production of carbon ferrochrome, the original Roots vacuum pump unit as a vacuum extraction unit, due to pumping furnace gas contains a relatively large amount of metal dust, although the dust Took some measures, but did not completely eliminate the impact of dust on the pump group, resulting in mechanical pump often damaged, a large amount of maintenance, it decided to use steam jet pump as a pumping
