High alumina low cement castable/Refractory Castables/Refractory castables free sample
Introduction:
High alumina castable has the advantages of high refractoriness, good workability and quick construction speed. According to the types of binders, high alumina castable is classified into ordinary high alumina castable, low cement high alumina castable, no cement high alumina castable and so on. The applications of high alumina castable are: burner nozzle working lining, electric furnace tapping spout, shaft lime kiln high temperature zone, rotary kiln hood, power plant boiler, etc.
Feature:
1. high strength
2. good thermal shock resistance
3. good corrosion resistance
4. good slag resistance
Application:
It's mainly used for furnace lining of boiler, blast furnace, hot blast stove, heating furnace, ceramic kiln and various industrial furnaces.
