Product Description

Regrinding Used Fused Zirconia Corundum Block AZS Refractory Brick for Glass Furnace
The Description:
Fused zirconium corundum brick also known as AZS fused zirconium corundum brick, AZS brick, fused cast AZS brick, etc., the English abbreviation is AZS, is according to the three chemical components of Al2O3-ZR02-sio2 ternary phase diagram, according to the order of its content, Al2O3 takes A, Zr02 takes Z, Sio2 takes S, the national standard adopts this abbreviation, For example, No. 33 fused cast zirconium corundum brick, abbreviated as AZS33#, No. 36 fused cast zirconium corundum brick, abbreviated as AZS36, No. 41 fused cast zirconium corundum brick, abbreviated as AZS41, where 33, 36, 41 are named according to the content of zirconia (ZrO2), For example, fused zirconium corundum brick AZS41# refers to fused zirconium corundum brick with 41% zirconia content, fused zirconium corundum brick AZS36# refers to fused zirconium corundum brick with 36% zirconia content, fused zirconium corundum brick AZS33# refers to fused zirconium corundum brick with 33% zirconia content.
Application of Y-AZS 41#WS Straight brick:
Y-AZS 41#WS is mainly used in the bottom of the melting pool, the wall brick of the pool, the kiln wall, the electric furnace flow channel and other key parts of the melting furnace.

Product feature:
1: High fire resistance
The refractoriness of fused bricks is higher than that of clay bricks and semi-silicon bricks, up to 1750-1790°C, which is a high-grade refractory material.
2: high softening temperature under load
Fused zirconium corundum brick has high zirconium content, less impurity mass, and the load softening temperature of zirconium corundum products is generally above 1600 degrees.
3: Strong erosion resistance
High density, high resistance to liquid glass and gas scour
4 Resistance to chemical erosion
Zirconium refractory products are resistant to acid or alkaline slag, metal erosion and oxidation, reduction reactions are very good, and with the increase of zirconium content, harmful impurities content decreased and enhanced.
