Wear Resistance Monolithic Castable Refractory / Anti Wear Dense CFB Boiler Refractory
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 different parts of CFB boiler.Compared with traditional castable, which can greatly improve the boiler’s running time.
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.
Wear resistant castable refractory produced by Jundao with the characters:
High strength,
Good high-temp performance,
Volume stability,
Small thermal conductivity,
Strong anti-slag penetration and erosion resistance,
Easy to construct and good structural integrity etc.
Wear resistant castable refractory is mainly used for the difficult to construct, wearing and tearing badly parts of CFB boiler.
