Refractory Bricks
Magnesia aluminum bricks use magnesia as the main raw material, magnesia brick and aluminum oxide as the co-milled fine powder as the matrix, the alkaline products which are fired at high temperature are called magnesia alumina bricks.
Product Description
Magnesia aluminum bricks use magnesia as the main raw material, magnesia brick and aluminum oxide as the co-milled fine powder as the matrix, the alkaline products which are fired at high temperature are called magnesia alumina bricks.
Magnesia aluminum refractory bricks have good thermal shock resistance, high mechanical strength at high temperatures and high softening temperatures.
Magnesium aluminum fire brick has good slag resistance, high temperature performance and thermal stability, and the price is cheaper than magnesium spinel.
Magnesium aluminium bricks used in ladle, mixed iron furnace, glass kiln regenerator, steel reverberative kiln roof, steel making furnace permanent lining and refractory industrial high temperature kiln.
