Oxygen blowing of medium and low carbon ferrochrome: The equipment used for refining medium and low carbon ferrochrome by oxygen blowing is a converter, so it is called the converter method. According to the different oxygen supply methods, oxygen blowing can be divided into four types: side blowing, top blowing, bottom blowing and top and bottom combined blowing. my country adopts the top blowing converter method. The oxygen blowing method is to blow oxygen directly into the liquid high carbon ferrochrome to decarburize it and obtain medium and low carbon ferrochrome. The main elements in high carbon ferrochrome are chromium, iron, silicon and carbon, all of which can be oxidized. The main task of oxidative blowing of high carbon ferrochrome is to decarburize and preserve chromium. When oxygen is blown into the liquid high carbon ferrochrome, since the content of chromium and iron accounts for more than 90% of the total alloy, the first thing to be oxidized is chromium and iron, and then these oxides oxidize the silicon in the alloy. Due to the oxidation of chromium, iron and silicon, the temperature of the molten pool increases rapidly, and the decarburization reaction develops rapidly. The higher the temperature, the more conducive to the decarburization reaction, and the oxidation reaction of chromium can be inhibited, and the carbon in the alloy can be reduced.
