AZS Refractory Bricks & Blocks are produced from alumina powder, zirconia sand and
additive. Zirconia content defines their corrosion resistance. AZS Fused Cast Refractories are
the most widely used materials in glass melting furnaces, frit kilns and occasionally some foundry
plants. AZS Refractory Bricks have low potential for stoning, blistering and exudation of the
matrix glass. Therefore, most suitable for use in superstructures of melters, side walls of refiners,
paving blocks, and forehearth channel blocks.
Characteristics of AZS Refractories
High refractoriness under load
High-temperature endurable
Strong corrosion resistance
High thermal shock resistance
Good volume stability at high temperature
Low pollution
High hot crush strength
Good spalling resistance
Good wear resistance
Fused Cast AZS Applications
Important parts of furnaces where chemical erosion is serious and temperature
changes frequently
