Product Description

Description of 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 refractory 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 fire 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

  • Low-porosity clay bricks are widely used in glass kiln regenerator；
  • Low-porosity clay fire bricks are widely used in large-scale blast furnace supporting hot blast stoves；
  • Low-porosity clay bricks are widely used in the middle and lower lattices and support arches of the regenerators of hot blast stoves；
  • Low-porosity clay refractory bricks are widely used in various high-temperature industrial kilns such as lime kiln high-temperature zone firing zone.
