Knowledge of oxidizing and blowing high carbon ferrochrome
High carbon ferrochrome applicable to a wide range of industries, because high carbon ferrochrome texture is hard, has an excellent wear resistance and high temperature resistance, so high carbon ferrochrome is also more popular, high carbon ferrochrome supplier to take you to understand its oxidation blowing method:
First of all, the main task of oxidizing and smelting high carbon ferrochrome is to decarbonize and protect chromium. When oxygen is blown into liquid high carbon ferrochrome, because the content of chromium and iron accounted for more than 90% of the total alloy, the first oxidation is chromium and iron.
Second, these oxides oxidize the silicon in the alloy. With the oxidation of chromium, iron and silicon, the temperature of molten pool increases rapidly, and the decarbonization reaction develops rapidly. The higher the temperature is, the more favorable the decarbonization reaction is, and the oxidation reaction of chromium can be inhibited, and the lower the carbon in the alloy can be decreased. In short, oxidation smelting method is to blow oxygen directly into the liquid high carbon ferrochrome, decarbonized and produced medium and low carbon ferrochrome, can get more kinds of ferrochrome.
