High Alumina Low Cement Refractory Castable
Introduction:
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.
The high-aluminum high-strength wear-resistant castable is based on the traditional ratio, the particle gradation is adjusted, different additives are added, the amount of cement is reduced, the performance is improved, the intermediate temperature strength and the load softening temperature are increased, and the thermal conductivity is reduced. Good thermal stability.
Advantage :
The high-aluminum and high-strength wear-resistant castable is equipped with anti-penetration, erosion resistance, impact resistance and abrasion resistance, good mechanical properties, strong integrity of the furnace body structure, air tightness is better than brick furnace, extend the furnace age, save furnace repair Cost and economic benefits are remarkable. High-strength high-alumina wear-resistant castables are widely used in different parts of furnace linings such as power stations, boilers, melting casting furnaces, heating furnaces, soaking furnaces, heat treatment furnaces and induction furnaces.
High Alumina Castable 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
