48% SiO2 Mullite Insulating Brick For Industry Kiln Stove
Mullite Insulating Refractory Brick Production Mullite Insulating Bricks for Industry Kiln Stove
Description:
Mullite Insulating Refractory Brick Production Mullite Insulating Bricks for Industry Kiln Stove 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 chomical demands.
Mullite Insulating Refractory Brick Production Mullite Insulating Bricks for Industry Kiln Stovecan be used in linings or heat-insulating materials of the industries, such as, ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc
Mullite Insulation Brick can be used as working lining, where contact with flames directly. This kind of brick can save the kiln energy very much
Raw Material Selection
To ensure the quality of our raw materials, we only purchase our raw materials from our long-term trusted suppliers. With every purchase, the raw material must be passed 2 times inspection, 1 time at our supplier's site. a second inspection on the batch after the material arrived to our factory. Each time raw materials enter our facility, they are inspected again prior to being accepted.
