Zhengzhou Sunrise Refractory Co., Ltd.
Fused cast alpha-beta alumina products is mainly composed of Al2O3 whose contents is more than 94 percent , and it is produced by melting and casting high purity alumina in electric furnace at 2000C, alpha-beta corundum products is formed when alpha alumina and beta alumina inter-combine during their crystallization stage. This process directly leads to its dense structureformed, so this brick has excellent endurance to strong alkali. Under 1350C, it has strong corrosion resistance and almost does not contaminate to glass melting liquid . Because it does not contain impurities such as Fe2O3 and TiO2, when it comes into contact with glass liquid, air bubbles are rarely found. Therefore, this product has the special characteristic of minimizing contamination to glass liquid.
Features
1. High refractoriness
2. Better resistance to glass liquid
3. Excellent thermal stability
Application
Fused cast α-β aluminabricks is a typical glass contact material for the end zones of furnaces such as working-end, feeder channels when pure glass is required.
