Magnesia Alumina Carbon Brick / Alumina Magnesia Carbon Brick / Magnesia Calcium Brick

Magnesium alumina carbon brick

Magnesia alumina carbon bricks with high grade magnesite, corundum, spinel and graphite as raw materials, bonded by resin, are characterized by good slag resistance, they are mainly used for ladle upper and lower slag line.

Alumina magnesia carbon bricks with high grade bauxite, corundum, spinel, high purity magnesite and graphite as raw materials, bonded by resin, are characterized by erosion and corrosion resistance and spalling resistance. They are mainly used for ladle slag lining and bottom.

Magnesia calcium bricks are formed from high quality complex magnesia calcium sand. The composition ratio of Mgo/Cao can be adjusted according to the different applications. Formed at high temperature, vacuum pressure, impregnating pitch or paraffin wax. They have high temperature resistance and good slag resistance and are mainly used used for AOD and VOD furnace etc.
