Description

The manufacturing technique of phosphate refractory bricks is same as  phosphate castable. With rapid development recent years, phosphate refractory brick is remarkably effective in cement kiln and electric furnace roof.
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.
