Mullite bake-free Castable


Mullite bake-free castable is a refractory castable which is made of high quality porous mullite aggregate as raw material, with fine powder and additives. The critical particle size of mullite aggregate is 12 mm, and the long-term service temperature is 1350 degrees. High temperature can be used directly in contact with flame as working lining to achieve high temperature and energy saving; light unit weight, 40-60% reduction of structural weight, eliminating the hidden danger of brick breakage in hanging bricks on the top of the furnace; low thermal conductivity, low thermal conductivity and good thermal insulation performance with porous mullite aggregate ingredients; fast oven drying, shortening the duration of oven drying, and remarkable economic benefits This is the case.
