Clay Brick
Low-porosity clay bricks are typical clay refractory products. Low-porosity clay bricks have better high-temperature volume stability, lower creep rate and better wear resistance. The raw materials of low-porosity clay bricks include sapphire aggregate, light and soft clay binder, and auxiliary materials (kyanite , Sillimanite, andalusite) and additives, etc., after reasonable classification, the raw materials are fully mixed, then formed under high pressure, and sintered at 1400 ℃ high temperature conditions. The raw materials for the production of low-porosity clay bricks should require a compact structure, high purity, and few impurities.

Characteristics of Clay Brick
- Low porosity
- High load softening temperature
- Excellent thermal shock resistance
- Good volume stability
- Good mechanical strength
- Good wear resistance
- Resistance to penetration
- Acid resistance and slag corrosion resistance.
Application of Clay Brick
- Glass kiln regenerator；
- Low-porosity clay bricks are widely used in large-scale blast furnace supporting hot blast stoves；
- Mainly used in the middle and lower lattices and support arches of the regenerators of hot blast stoves；
- In addition, various high-temperature industrial kilns such as lime kiln high-temperature zone firing zone.
