Refractory resist bricks for fire furnace construction
General description
Refractory brick is a kind of insulation material adoption organic matter as ignition loss
substance in order to increase the porosity, small volume density , good insulation effect,
high mechanical intensity ,small thermal conductivity and low heat storage. They are widely
used in Fire – Clay Insulating Refractory Brick, High-Alumina Insulating Refractory Brick ,
Diatomaceous Insulating Brick,High Grade Insulation Brick :XJM Series Light Weight
Insulation Brick ,B Series Thermal Insulation Brick,Calcium Silicate Insulating and Refractory
Products, Clay Insulation Brick, Foam Diatomite Insulation Brick,and LightWeight
Insulation Brick.
Features
Lower heat storage than denser refractories
low levels of iron and other impurities
Lightweight and energy-efficient
High compressive strength
Typica application
Electrolytic Aluminum Industries
Iron & Steel Industries
Non-Ferrous Metals Industries
Glass Industries
Ceramics Industries
