The function of VOD Refining

An out-of-furnace refining technology for producing high chromium stainless steel by blowing oxygen to decarburize and blowing argon with stirring. It is the abbreviation of the vacuum oxygen blowing decarburization method.

The VOD method is the top blowing oxygen decarburization under the condition of vacuum decompression, and the argon blowing at the bottom of the bag promotes the circulation of the rigid liquid, which can easily reduce the carbon in the steel to 0.02 when smelting stainless steel There is almost no chromium oxide in the range of %~0.08%. The vacuum treatment of molten steel, coupled with the stirring effect of argon, the kinetic conditions of the reaction are very favorable, and good degassing and inclusion removal effects can be obtained.
