AOD refining method is the abbreviation of argon oxygen decarburization method. When refining stainless steel, it blows oxygen into molten steel under standard atmospheric pressure, and blows inert gas (Ar, N2) to achieve the effect of false vacuum by reducing CO partial pressure, so that the carbon content is reduced to a very low level. level, and inhibits the oxidation of chromium in steel.

According to the amount of slag to determine the silicon content of molten iron, P2O5 must be formed dur
