The advantages of AOD refining

 AOD refining method is the abbreviation of Argon Oxygen Decarburization. When refining stainless steel, it blows oxygen into the molten steel at standard atmospheric pressure while blowing inert gases (Ar, N2) to reduce the partial pressure of CO to achieve the effect of false vacuum, thereby reducing the carbon content to a very low level, and inhibit the oxidation of chromium in steel.

The advantages of the AOD refining method include:

Its high recovery rate of refined chromium, suitable for the production of low-carbon and ultra-low-carbon stainless steel, easy to control the S content in special steels below 0.005%;
Low requirements for raw materials, cheap high-carbon chromium can be used.
Iron can use 100% recycled scrap to produce stainless steel;
In the high-carbon zone, the blowing speed is fast and the reaction kinetic conditions are superior;
The equipment is simple, the operation is convenient, the infrastructure investment is low, and the economic benefits are significant.
