Product description
K 26 firebrick 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.
Advantages of k 26 firebrick:
Low thermal conductivity, low hot melt, low impurity content, fire resistance and temperature resistance, good thermal shock stability, significant energy saving effect, etc.
Application of k 26 firebrick
Used in refractory hot surface linings and backing insulation layers of other refractory materials, Refractory insulation materials for industrial furnaces such as cracking furnace tubular heating furnaces, reforming furnaces, hot blast furnaces, ladle insulation linings, shuttle kilns, tunnel kilns, ceramic track kilns, and push plate kilns in the steel, metallurgical, and chemical industries.

Packages and delivery:
Because k 26 firebrick with smaller bulk density whose strength is not as strong as heavy weight fire bricks, when delivering, CH Refractories will package insulating firebricks with special packages to protect insulating clay bricks from damage.
