Product Description
High-Temperature Resistant Azs Fused Zirconia-Mullite Firebricks Zircon Mullite Refractory Brick For Sintering Furnace
High alumina refractory brick series:
AZS-33
AZS-33 bricks are excellent in preventing the pollution of glass liquids. The possibility of causing glass stones, bubbles and basic glass phase precipitation is quite slim. It can be applied to the upper structure of melting pool, the tank wall corner tiles,paving bricks and other approaches as well.
AZS-36
AZS-36 bricks are the standard Fused Cast AZS Refractory bricks brick which boasts of the quality of particularly high corrosion resistance of glass liquids and low pollution. More than that, it has a balanced performance in the above two aspects. It can be applied to the direct access of glass furnace and glass liquids, such as melting tank wall corner tiles, paving bricks and charging door.
AZS-41
AZS-41 bricks are the best oxidated zircon corundum brick which possesses the quality of highest corrosion resistance of glass liquids and excellent low pollution of glass liquids. It can be applied to the locations of glass furnace which requires particularly high corrosion endurance, such as full-fused furnace, liquid pumps, furnace ridge, bubbling brick and bricks of charging door corners.
