Differences between AOD and VOD furnaces

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.

Learn details of VOD smelting stainless steel denitrification method

Vacuum oxygen decarburization refining furnace smelting stainless steel denitrification method, the carbon content of stainless steel water before treatment in vacuum oxygen decarburization refining furnace is required to be controlled at more than 0.30%, after oxygen desiliconization, carbon, oxygen content in molten steel.

Types of secondary refinement

Dephosphorization of molten steelAt present, the single-use converter process can reach a phosphorus content of 40-100 ppm, which depends on the silicon and phosphorus content in the molten iron. According to the amount of slag to determine the silicon content of molten iron, P2O5 must be formed dur
