Fire Resistant Furnace Corundum Brick Fused Cast Alpha-Beta Alumina Block
Alpha-beta alumina is formed by the compact structure of alpha alumina and beta alumina crystals in a most ideal proportion. It has good corrosion resistance and stability. Its feature is that when in contat with molten glass, it barely produces any blistering or stones. So, alpha beta alumina blocks may be widely used in the areas such as working tank, feeder channels, superstructures, lipstone, etc. To improve glass quality.
Detailed Product Description
Quick Detail:
1.Compact microstructure
2.Good erosion resistibility to molten glass
3.Good thermal shock resistibility
4.Barely rendering blister
Application:
1. α-β-Al2O3 TY-M has no contamination to 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.
2. 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.
3. 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.
