CH Refractories is professional manufacturer of AZS block for more than 30 years, there are many reliable domestic and abroad customers in our company. Now we are purchase recycling AZS Blocks from our customers and then sell to some customers who need it. We will remove damaged parts on the blocks and then polish into standard size. The inner part of Recycling AZS Block is not eroded by glass mental, so after removing damaged parts outside, the Recycling AZS Block still with good performance and much cheaper price than new products.
If you need recycling AZS Block, please contact us for best price.
Glass Kiln Applied Fused Cast AZS Block is also named AZS brick. It
is based on three chemical components of the Al2O3-ZrO2-SiO2
ternary phase diagram and widely used for glass kiln. The glass
kiln brick is arranged according to the order of its contents.
Al2O3 takes A, ZrO2 takes Z, and SiO2 takes S. The national
standard uses this abbreviation. For example, No.33 cast zirconia
corundum brick, abbreviated as AZS-33#, No. 36 cast zirconia
corundum brick, abbreviated as AZS-36#, No. 41 cast zirconia
corundum brick, abbreviated as AZS-41#.
AZS-33# Brick to prevent contamination of glass liquid is
particularly superior, it causes stones in glass, bubbles and basic
glass phase precipitation trend is very small. It is suitable for
the upper structure of the glass melting pool, the wall brick of
the working pool, the paved brick and the material channel.
AZS-36# Brick is a standard zirconia fused zirconium corundum
brick, which has the characteristics of high corrosion resistance
and low pollution resistance of glass liquid, and the performance
in these two aspects is balanced. The fused cast AZS brick is
suitable for the parts in the glass furnace which are in direct
contact with the glass liquid, such as the wall brick of the
melting pool, the paving brick, the feeding port and so on.
AZS-41# brick is very high-grade zirconia fused zirconium corundum
brick, it has very high corrosion resistance of glass liquid and
outstanding low pollution to glass liquid. It is suitable for the
parts with high corrosion resistance in glass kiln, such as full
electric furnace, fluid hole, kiln, bubble brick, brick at the
corner of feeding, etc.
Applications of Zirconia Corundum(AZS) Brick:
Widely be used for linings of furnace in glass industries.
