High Alumina Light Weight Insulating Castable Refractory Heat Insulation
High strength high alumina castable is made of super high alumina clinker, composite binders and adhesives. The products are featured with high strength, good wear resistance, permeability resistance, erosion resistance, good mechanical properties, convenient construction, etc. It is commonly used in top of CFB boiler furnace, rear wall, etc.
Characters of refractory castable:
1. High refractoriness, high refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.
5. Good resistance to flake performance.
6. Good thermal shock stability.
7. Scouring resistance
8. Good hot strength.
Application of the refractory castable :
1. Furnaces of metallurgy industry, heat treatment furnace.
2. Furnace of incineration of garbage, recirculating fluidized bed furnace.
3. Furnaces of chemical industry and construction industry.
4. Tundish lining
