Details of refractory fused AZS block
Fused Cast Bricks are mostly used for glass industry.Typical applications are superstructures, skew blocks, wall bricks and upper-checker in regenerators, paving, sub-paving and forehearth blocks in float glass furnaces.
AZS fused cast block is also called fused cast block which is abbreviated as AZS because it contains Al2O3-ZrO2-SiO2. Fused cast AZS block is made from pure alumina powder and Zircon sand (composed of 65% zirconia and 34% SiO2). After Alumina powder and zircon sand melting in electric furnace, they are casted into various molds and cool themselves down to become white solid. Because of the different content of Zirconia from 33%-41%, our fused cast AZS blocks can be divided into three types AZS—33#,AZS—36# and AZS—41#.
The term Fused Cast refers to a manufacturing process in which the ceramic bonding is obtained by the solidification of a mixture which has been melted in an electric furnace and cast in liquid state into molds.
