Phosphate castable refractory

Detailed introduction

(1) Phosphate refractory castable shows that phosphate refractory castable is a kind of refractory castable with excellent performance which is made up of coarse aggregate, fine aggregate and powder of bauxite clinker plus phosphoric acid and high alumina cement.
(2) Phosphate refractory castable characteristics: use temperature 1400 ~ 1450, high strength, medium temperature strength does not decline, good thermal stability. It is a good material to repair furnace lining quickly and without cracking.
(3) Phosphate refractory castable used parts: suitable for industrial kilns and other thermal equipment lining wear parts. At the same time, it can be used as repairing material for lining without adding coagulant.
