AZS Fused Cast refractory used for melting glass furnaces Crown Brick Used in Crater position of Glass furnace

 AZS Fused Cast Crown Brick Used in Crater position of Glass furnace

AZS refractories are used for melting glass furnaces, can stand aggressive conditions in contact with molten glass.

The different content of ZrO2 led to three model: AZS33#,

                                                                        AZS36#,

                                                                        AZS41#.

Our company produce the AZS Fused Cast Refractories as per different use and customer requirement.

We have four casting method: Normal casting;

                                            Tilt casting; 

                                            Semi-Void-Free casting;

                                            Void-free casting.
