AOD (Argon Oxygen Decarbonizer)

A secondary steelmaking process is carried out during which oxygen and argon are blown into the molten steel. This method enables carbon to be removed without oxidising chromium for refining stainless steel. Molten metal is stirred and homogenized to achieve the perfect level of alloying. At MISIL, special stainless steel grades are made through AOD process. The only plant in Pakistan capable of manufacturing 60,000 tons per annum of stainless steel billets in conformance with 200, 300 and 400 series, through AOD (Argon Oxygen Decarburizer) converter having capacity of 18 tons per heat.
