Mullite Castables

Mullite castables are a kind of refractory castables which is made of high quality porous mullite aggregate and are stirred with fine powder and additives. The general formulation is 3Al2O3∙2SiO2. It has high compressive strength, good high-temperature endurable stability, thermal shock resistance, excellent wear resistance, erosion resistance, etc., and can be used for the lining of large power station boiler wear lining and other high-temperature kilns.

Mullite refractory castables are 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 castables have high use temperature and can be directly contacted with the flame for working lining to achieve high temperature and energy saving, the unit weight is light, the structure weight is reduced by 40-60%, and 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.
