Detailed Product Description

Wear-resistant phosphate brick special unburned phosphate bonded high alumina refractory brick for cement kiln

 

Product Description

Phosphate bonded high alumina bricks are made from high alumina bauxite aggregate, selecting phosphoric acid or aluminum phosphate as binder. Finished phosphate bonded high alumina brick must go through 400~600 ℃ heating process and semi-dry compress process. Featured by high wear-resistance, high refractoriness and good thermal shock resistance, phosphate bonded high alumina bricks are widely used in rotary cement kiln transition zone, sintering zone, cooling zone and cooler working layer.

 

Phosphate Bonded High Alumina Bricks Features:

 

High mechanical strength
High refractoriness
Good wear resistance
Good spalling resistance
