Mullite-Sillimanite bricks

Description:

 

Mullite-Sillimanite bricks are made from good quality and superpure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture. Each grade of products has unique design to meet different thermal, physical and chemical demands.

Mullite-Sillimanite bricks primarily used for the key parts of the furnace of glass furnace, alkali-free glass fiber furnace, blast furnace hot blast stove, refractory-material tunnel kiln, etc.

 

We can produce common shaped and irregular shaped refractory brick. And we can adjust our specifications for your application.
