在一般的铸造生产中,冲天炉是常用的化铁炉,铁水的化学成分通常是在熔化过程中通过调节炉料的比例来控制的。但在实践中证实,炉内控制化学成份有许多局限性。最近,美国采用了一种碳化硅铁碳反应炉(Carborundum Ferrocarbo Reation Vessel)工艺—简称RV法,解决了这些问题,使冲天炉操作者从许多的约束中解放出来。下面对RV法作简单介绍。 In general foundry production, cupola furnace is commonly used iron furnace, the chemical composition of molten iron is usually controlled by adjusting the ratio of charge in the melting process. However, it has been proved in practice that there are many limitations in the control of chemical composition in the furnace. Recently, the United States adopted a Carborundum Ferrocarbo Reation Vessel process, referred to as the RV method, to solve these problems and free the cupola operator from many constraints. The following RV method for a brief introduction.
