  • Argon oxygen decarburization Wikipedia

    Argon oxygen decarburization (AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminum.After initial melting the metal is then transferred to an AOD vessel where it will be subjected to three steps of refining; decarburization, reduction, and desulfurization.

    AOD slag samples from steel s of Outokumpu Stainless Company were used to study F-dissolution relating to treatments for volume stabilization. Results from the slag tests and sample characterizations indicate that the slag re-melting with or without reduction and granulation with either water or gas have rather small effects on F leaching, as well as formation of different C2S polymorphs.

    Laboratory treatment tests of AOD slag from stainless steelmaking have been performed by MiMeR. An induction furnace was used for slag reduction tests. The reduced slag was either water granulated or cooled in an Al2O3 crucible. Metal droplets, suitable for recycling as metallic materials in the steelmaking, were recovered after the slag
