本专利低炭铬铁生产方法的要点是:在熔化铬矿的工序中,通过加入适量的氧化物以控制铬、铁元素的进一步氧化,减少硅铬合金的消耗,从而降低低炭铬铁的生产成本。众所周知,由于铬与炭的亲合力较强,所以低炭铬铁的传统生产方法是:用硅铬合金还原铬矿生产低炭铬铁。而硅铬合金则是按照下述两种方法来生产的:其一是用焦炭
The patented low-carbon ferrochrome production method has the following main points: in the process of melting the chrome ore, the oxidation of the low-carbon ferrochrome can be reduced by adding appropriate amount of oxide to control the further oxidation of chromium and iron and reduce the consumption of the silicon-chromium alloy Cost of production. As we all know, due to strong affinity of chromium and carbon, low-carbon ferrochrome is the traditional production method: chromium-chromium alloy with silicon-chromium alloy to produce low-carbon ferrochrome. The silicon-chromium alloy is in accordance with the following two methods to produce: One is the use of coke
