Argon Oxygen Decarburization for Metal …

AOD provides an economical way to produce stainless steel with a minimal loss of precious elements. It is part of a duplex process in which scrap or raw materials are first melted in an electric arc furnace (EAF) or induction furnace. The molten metal is then decarburized and refined in a special AOD vessel to less than 0.05% carbon.
