Refractory Castable Introduction:
Micro expansion plastic refractory castable is featured with strongroom temperature plasticity, good adhesion strength, natural drying, micro expansionunderhigh temperature, high refractoriness, good sealing performance, convenient construction, etc. It is commonly used in CFB boilers, chimney lining, 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
