Brief introduction:

 

Our company can produce serious specification fused cast 33#,36#,41#AZS block for glass furnace ,and its output is over 5000tons per year. AZS series blocks are made from high qulity raw materials and machined through refined grind processes. So qualities of these refractory products can be guaranteed.

 

Application:

 

AZS 33 PT are mainly used for working ends, feeder channel, superstructures and top crowns.

AZS 33 ZWS(RR) are mainly applied for sidewalls;

AZS 33 WS (RT) are mainly used for sidewalls, tank bottom, superstructure, C-shaped brick and doghouse crown
