用氧气转炉将碳素铬铁吹炼成中、低碳铬铁,以代替传统的生产中、低碳铬铁的电硅热法,具有许多潜在优点,所以苦干年来在各国受到注意。发表过一些关于顶吹、面吹、侧吹的工业性试验结果。我国不但进行了小型顶吹试验,还初步试验了底吹氧,效果较好。但迄今为止,关于铬铁吹氧脱碳的物理化学基础,似乎还没有经过认真研讨。铁合 Carbonaceous ferrochrome blowing into medium and low carbon ferrochrome with oxygen converter has many potential advantages instead of the traditional electric and thermal heating method for producing medium and low carbon ferrochrome, so it has been paid attention in various countries for many years. Published some of the top-blowing, surface blowing, side blowing industrial test results. Our country not only carried out a small top-blowing test, but also initially tested the bottom blowing oxygen, the effect is better. So far, however, there has not been a serious discussion of the physico-chemical basis for the chromate blowing oxygen decarburization. Iron together
