用氧气转炉将碳素铬铁吹炼成中碳、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,所以几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 ferrochromium is converted into medium-carbon and low-carbon ferrochromium by oxygen converter to replace the traditional electric silicon heating method for producing medium and low-carbon ferrochromium, which has many potential advantages. Therefore, it has been attracting attention in various countries for several 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
