Types Of Refractory Bricks Mullite-Sillimanite Brick For The Key Parts Of The Furnace
Quick Detail:
1. good refractory properties;
2. good stability against thermal shocking;
3. use high quality raw material;
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.
Applications:
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.
