AOD, which is short for Argon Oxygen Decarburization, is the dominant refining method for stainless steel. During the operation, the molten steel from EAF is charged into AOD furnace, before oxygen and argon is blown from the tuyere at the sidewall to conduct decarburization. Yanmu offers a whole series of refractory products for AOD furnace.
Yanmu’s magnesia-dolomite Brick is our primary product for AOD lining, due to its excellent slag-resistance and thermal-shock-resistance property. Other advantages of it include the steel-purification-effect and relatively less inclination to hydrate.
Magchrome brick is provided by Yanmu as an alternative product, which is used typically at tuyere area at very high temperature.
For permanent lining the standard magnesia brick is recommended.
Yanmu offers also series of unshaped product such as ramming mix, moldable, filling materials, and refractory mortar, which can be applied to different part or in different installation scenario of AOD furnace.
