Insulating Firebrick

 

Shanghai GongYe provides a complete range of insulating firebrick (IFB) that offers unsurpassed performance and value for a wide variety of industries and applications. Different grades of insulating firebrick are manufactured according to international standards, and are suitable to operate in various temperatures and atmospheres up to 3000º F.

 

Features of Insulating Firebrick:

 
  • Excellent strength at ambient and elevated temperatures
  • High compressive strength
  • Every brick ground to precise dimensions
  • Very low levels of iron and other impurities
  • Lightweight and energy-efficient
  • Lower heat storage than denser refractories
  • Heats quickly and economically to operating temperature
  • Cools fast to speed periodic operations.
 

Typical Applications of Insulating Firebrick:

 
  • Glass Industries
  • Ceramics Industries
  • Electrolytic Aluminum Industries
  • Iron & Steel Industries
  • Non-Ferrous Metals Industries
  • Power Generation Industries
