Introduction of α-β Alumina TY-M:
TY-M has no contamination of glass melt , dense structure , excellent corrosion resistance of glass melt below 1350℃。 It is the ideal refractory material for channel, feeder channel, spouts and working ends of glass furnace.
Al2O3 Chemical Composition: 94 %
SiO2 Chemical Composition: 1 %
NaO2 Chemical Composition: 4 %
α-Al2O3 Crystallographic Analysis: 44 %
β-Al2O3 Crystallographic Analysis: 55 %
Vitreous Phase Crystallographic Analysis : 1 %
Fused cast Alumina Block TY-M is formed by the compact structure of α alumina and β alumina crystals in a most ideal proportion which is approximately 50% and 50% respectively,where intertwined crystals of both materials result in a very dense structure.
▶ Specifications and applications:
--Below 1350 ℃, it has excellent corrosion resistance against molten glass and great performance against contamination to molten glass, thus it is very suitable for paving blocks and fore-hearth channel blocks.
--When in contact with molten glass, it barely produces any blistering or stones. So, α-β alumina blocks may be widely used in working tank, feeder channels, superstructures and lipstone, etc.
--In general, in soda-lime container furnaces α-β alumina fused-cast is installed in the Alcove and channel areas, as alternative to AZS fused-cast for Alcoves and as alternative to AZS fused-cast, zirmul, sinter-alumina and other sinter refractories for channels.
