Product Introduction
Mullite castable is mainly made of porous mullite aggregate, and stir into a fine powder and additive. The long term using temperature is 1350℃. It can direct contact with the working lining using flame and achieve high temperature energy saving.
Features
1.Low thermal conductivity.
2.Good heat preservation performance.
3.High mechanical strength.
Application
Mullite castables are used in petrochemical industry tubular heating furnaces, light diesel oil,sulfur recovery devices, steam boilers and pipe insulation floor, other industrial furnace doors, fire holes, observation hole door linings, etc.
