Wear-Resistant Special Unburned Phosphate Brick High Alumina Refractory Brick Phosphate Brick
Phosphate brick uses high bauxite clinker,corundum and mullite as the main raw materials, and adopts phosphate chemical bonding technology.The product has the following characteristics:high compressive strength, low porosity,good thermal shock stability, good wear resistance strong anti-peeling ability；The phosphate brick is suitable for the firing zone, and the phosphate wear-resistant brick is suitable for the cooling zone and the exothermic reaction zone and the end of the decomposition zone. In the cement industry, phosphate bricks are replacing high aluminum bricks and are widely used.
