IntroInsulating Fire Brick
Overview
Insulating Fire Brick is a lightweight and lower density material, provides excellent thermal insulation. Low heat storage and thermal conductivity due to porous structure, it has excellent thermal insulation performance.
Based on its excellent thermal conductivity, it is mainly used in petrochemical cracking furnaces and heat treatment furnace where operation and shut-down are repeated.
