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:

 

This kind of refractory bricks are mainly used for sidewalls, doghouse, throat, bottom budding, dam blocks, electric block corners, etc.

 

 

we also produce other models of AZS, their properties are detailed in the table below:
