Advantages of Phosphate Refractory Brick
Higher strength and good wear resistance.
Good chemical resistance. (The alkali resistance is better than clay bricks and high alumina bricks)
Good thermal shock resistance.
The load softening temperature is higher.
Customerize mould according to different size requirements for free
Application of Phosphate Refractory Brick:
Transition zone of the rotary kiln, the kiln mouth, the kiln door cover, the lining of the cooler and other parts of the refractory brick that are easy to loose and fall.
CH Refractories has been major in fire bricks, castable and ramming mass manufacturer for more than 30 years.
