70%Al2O3 High strength dense wear resistant Castable Refractory for Circulating Fluidized Bed Boiler
The CFB boiler construction body is extremely complex, the factors of large amount of construction, high pulverized coal flow rate and large flow that demand the lining refractory with high strength, good wear-resistance, and excellent workability.
Jundao(Henan) New Materials Co.,Ltd. Produces common, high strength wear-resistant castable refractory, high-Al, SiC, Corundum self-flow wear-resistant castable used for difficult to construct, wearing and tearing badly parts of CFB boiler.
High strength dense wear-resistant castable refractory produced by Jundao compared with traditional castable, which can greatly improve the boiler’s running time. The product with the characters:
High strength
Volume stability
Small thermal conductivity
Strong anti-slag penetration and erosion resistance
Good high-temp performance to work at high temperature for long time
Easy to construct and good structural integrity that improve working efficiency
