Magnesia Dolomite Brick Series

Magnesia Dolomite Bricks 30

Made of high-quality magnesite and dolomite. It is made into magnesia-dolomite sand by two-step calcination process (light burning, fine grinding, ball pressing or blanking, dead burning), and then choose the appropriate MgO according to different needs. (CaO ratio, crushed, mixed, formed, and fired at high temperature.) It has high temperature mechanical strength, good thermal shock stability, excellent resistance to chemical impregnation, good high temperature creep and can purify molten steel. It is an ideal material for stainless steel smelting and is used for masonry of AOD furnace, VOD furnace and ladle.
