实践证明,工频感应熔炼炉化铁,并不是简单的生铁再熔化,是有一定规律,适应这规律的应有相应的熔炼工艺,才能保证铁水有良好的铸造性能和得到优质的铸件;同时也能把炉衬寿命和生产率的某些矛盾统一起来,以符合增产节约的目的。 Practice has proved that the power frequency induction melting furnace iron is not a simple pig iron remelting, there is a certain law, to adapt to the law of the corresponding smelting process, in order to ensure a good casting performance of hot metal and get high-quality castings; the same time But also the lining of life and productivity of some of the contradictions unified in order to meet the production increase the purpose of saving.
