Phosphate High Alumina Brick

Phosphate bonded high alumina refractory brick is made of calcined bauxite as aggregate and fine powder, and phosphate as binders, being formed by drying press, and sintering at medium temperature of 400~600℃.

Classification by binders: Phosphate bonded high alumina refractory brick (P) , Phosphate bonded high alumina wear resistant refractory brick (PA)

High strength at high temperature

Higher refractoriness under loading

Good thermal shock resistance

Good chemical erosion and corrosion resistance

Widely used for rotary kiln linings of pre-heating zone, transaction zone, cooling zone.

Professional Suggestions

Recent years, following cement capacity largely demand, it requires the rotary cement kiln with long service life, it means the refractory lining materials must be with good quality. High alumina brick with high RUL and good wear resistance are designed for the rigorous working conditions to improve the refractory linings.
