AODis mainly used in steel smelting stainless steel refining equipment, and similar converter. Under normal pressure, blowing different proportions of argon-oxygen mixture gas (sometimes also be used to replace part of the nitrogen argon gas), control different stages of the refining process, reducing furnace CO partial pressure, the promotion of liquid steel in the C and O2 response, the main get rid to carbon and protect chrome purposes. Mainly applied to low-carbon stainless steel refining.
