casting white fused alumina for float glass furnace
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.
α-β-Al2O3 TY-M has no contamination of glass melt,dense structure,excellent corrosion resistance of glass melt below 1350°C. It is the ideal refractory materials for channels, spouts and working ends of floating glass furnace.
β-Al2O3 TY-H has high temperature,better alkali resistance and excellent thermal stability measuration.It is a new refractory material of float glass furnace of breast wall,Port mouth and top Crown.
α-Al2O3 TY-A :The typical glass contact materials for the end zones of furnaces (working-end, feeder channels) when glass quality is the priority : TV Glass, high quality container glass, float glass.
