Product description

Material and Technique

Magnesia dolomite bricks/magnesia calcium bricks for AOD funace use synthetic dolomite sand as raw materials, selecting MgO/ CaO ratio in accordance with different needs, which are produced by high heat sintering and vacuum pressure impregnation pitch or paraffin treatment. 

Magnesia dolomite bricks are of alkaline refractory products with a higher MgO content. Generally, MgO content of magnesia dolomite bricks is beyond 35%, then CaO content is more than 40%. In addition, Magnesia dolomite bricks also contain other impurities, such as SiO2, Al2O3, Fe2O3, etc.

Properties 

Magnesia dolomite bricks for AOD furnace have good resistance to elevated temperatures and high slag resistance.

Application 

As AOD furnace refractories, magnesia dolomite bricks are increasingly being used as linings for every part of AOD furnace, such as trunnion, tuyere, slag line, wall, bottom and furnace end.
