According to project & requirement, electro-cast AZS ZAC refractory bricks & blocks for glass or glaze furnaces.
Electro-fused AZS bricks & blocks are manufactured by mixing melted zircon and alumina in electric furnaces, casted and annealed in annealing furnaces.
AZS ZAC Refractory bricks are main stucture materials of glass furnaces since it can work under severe conditions during process of melting glass, does not contaminate with liquid glass, has high resistent to corrosion in contact area of melting glass.
Electro-cast AZS ZAC Refractory Bricks mainly used for glass and frit furnaces as lining bricks, side walls, working pool, spout brick, corner bricks.
