Low Cement High Temperature Fire Proof High Acid Resistance Mullite Refractory Castables

Mullite Castables

Introduction

Mullite castable as high alumina refractory castables is made of high quality porous mullite aggregate. The general formulation is 3Al₂O₃?2SiO₂. It has high compressive strength, good high temperature endurable stability and thermal shock resistance, excellent wear resistance and erosion resistance etc., and can be used for the lining of large power station boiler wear lining and other high temperature kiln.

Mullite refractory castable is mixed with fine mullite powder and other additives. The material ratio can be adjusted according to the actual use of the boiler to carry out customized production. The mullite aggregate has a critical particle size of 12 mm and a long term use temperature of 1350℃. The mullite refractory castable has high use temperature and can be directly contacted with flame for working lining to achieve high temperature and energy saving, the unit weight is light, the structure weight is reduced by 40-60%, the hidden trouble of the brick hanging brick is eliminated, the porous mullite bone Ingredients, low thermal conductivity, good thermal insulation performance, fast oven drying, shortening furnace life, significant economic benefits.
