AZS Fused Cast refractory firebrick use for melting glass furnaces, can stand aggressive conditions in contact with molten glass

AZS Fused Cast refractoriy firebrick(AZS33/AZS36/AZS41)  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(PT);

                                            Tilt casting(QX); 

                                            Semi-Void-Free casting(ZWS);

                                            Void-free casting(WS).
