Phosphate bonded high alumina brick

Phoshate bonded high alumina brick is a special refractory brick, phosphoric acid is used as a binder. Its advantage lies in its excellent wear-resistance performance.

Other name: Phosphate high alumina brick

Model Number: P, PA, SLI-80, SLI-75, GH-80, Shell, HAS, KF

Certification: ISO9001-14001

Minimum Order Quantity: 5 MT

Phosphate bonded high alumina brick

Introduction

Phoshate bonded high alumina brick has two types, phoshate brick and phoshate abrasion resistance brick. Using 42.5%-50% phosphoric acid as its binding agent and calcined bauxite as raw material, phosphate bonded high alumina brick is made by machine moulding. With development of fire blocks, high RUL brick, composite brick, kyanite brick and high strength with good wear-resistance brick are used as the substitute brick of phosphate bonded high alumina brick to solve other issues of rotary kiln.

Characteristic

1. High mechanical strength
2. Excellent abrasion resistance
3. High refractoriness
