High Alumina Insulation Brick

Introduction

Light weight high alumina brick is also named high-aluminium heat insulation brick, are used in building heat insulating walls or heat preserving walls, which is basically for preserving or insulation heat. Refractory insulation thermal brick contains more than 48% alumina oxide. This kind of thermal brick for sale does not directly exposed to high temperature inside kilns or furnaces, thermal brick only built closely to the kiln wall as insulations. Refractory insulation thermal brick is a good insulation refractory material, which has a high compressive strength, low thermal conductivity and good insulation quality.

Because refractory insulation thermal brick with smaller bulk density whose strength is not as strong as heavy weight fire bricks, when delivering, CH Refractories will package refractory insulation thermal brick with special packages to protect products from damage. 

Applications

Light Weight High Alumina Brick is used in parts that is not exposed to abrasions and high temperature of melted matters. They should not be applied in environment that has a temperature higher than 1400℃.
As a low price refractory material, the light weight high alumina bricks are applied in:
◆Ceramic tunnel kiln
◆Roller kiln and shuttle kiln
◆Furnace lining and insulation layers
◆Other Thermal Equipment & Heat Treatment Lining
◆Heating Furnace & Coking Furnace In Iron And Steel Industry

Advantages

◆High compressive strength
◆Widely application with different bulk density
◆Good insulation performance, low thermal conductivity
