Nitrided Ferro Chrome Lump

First of all, we must know that the main task of oxidation blowing ferrochromium is to decarburize and preserve chromium. When oxygen is blown into liquid high-carbon ferrochromium, since the content of chromium and iron accounts for more than 90% of the total alloy, chromium and iron are oxidized first.

Second, these oxides oxidize the silicon in the alloy. As chromium, iron, and silicon are oxidized, 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 can inhibit the oxidation reaction of chromium, and the lower the carbon in the alloy can be reduced. . In short, the oxidation blowing method is to blow oxygen directly into liquid ferrochromium to decarburize it, and can obtain more types of ferrochromium.
