Phosphate Bonded Insulation Refractory Fire Bricks with Size 230x114x65mm

Excellent thermal stability phosphate bonded high alumina brick for industrial furnace is made out of a naturally-occurring material known as bauxite.This material include aluminum hydroxide, which is what give the brick such great warmth resistance. High alumina efractory brick also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina.

Advantages:
  • No water required for installation, no risk of spalling or explosion due to rapid evaporation
  • Eliminate steel’s pinhole due to moisture problem,clean and quick installation
  • Low energy consumption for preheating as Dyracoat requires short preheating time, and is prompt for use as cold tundish (with preheating nozzles)
  • Minimum wall thickness can be maintained due to the use of a former,and easy to handle
