钒的还原主要是炉料熔滴过程中进行的,改善烧结矿的还原性能、降低初渣中(FeO)量、提高熔滴区料柱的透气性都有利于钒的还原,提高炉缸温度有利于钒的还原,适当提高炉缸氧势可获得含钒量较高的生铁。
The reduction of vanadium is mainly carried out during the droplet melting of the charge to improve the reduction performance of sinter, reduce the amount of FeO in the primary slag and improve the permeability of the material column in the droplet zone, which is beneficial to the reduction of vanadium and raising the temperature of the hearth Conducive to the reduction of vanadium, an appropriate increase in hearth oxygen potential available vanadium higher pig iron.
