Argon Oxygen Decarburization (AOD) Refractory Products - Resco Products

Argon-Oxygen Decarburization (AOD)

Argon-Oxygen Decarburization (AOD) is the most dominant process for the generation of stainless, low-alloy, and superalloy steels. Resco Products has been and is involved in this application with its ability to supply both dolomitic as well as magnesite chrome refractory products. The AOD process became very popular because it created a more economical way to produce specialty steels. This was achieved higher metallic yields with lower material costs versus previous methods used.

Scrap is first melted in an electric arc furnace (EAF) or an induction furnace (IF). Then transferred to the AOD vessel where it is decarburized and refined reducing the carbon levels below 0.05%. Argon and oxygen are injected through submerged tuyeres to reduce the oxidation of precious elements.

Resco works with the various AOD facilities to determine the best refractory product for their process. Resco's refractories increase the number of heats or contact hours per campaign. Achieving the lowest refractory operating costs possible by improving the argon-oxygen decarburization lining.

Refractories for AOD Vessels

Argon Oxygen Decarburization AOD DiagramThe most common products used for an argon oxygen furnace include dolomite burned brick, high fired magnesia chrome brick (mag-chrome). Dolomite brands utilized for AOD refractory include KD65Z-DOL and FG65-DOL. magnesite chrome refractory brands typically utilized in AOD lining include RFG-93 and Exceline FG-95.
