Product description
Insulating fire brick for forge 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.
Advantages of insulating fire brick for forge:
High temperature resistance:insulating fire brick for forge use high-purity alumina as the main component and have excellent high-temperature resistance. In high temperature environments, it can maintain stable physical and chemical properties, is not prone to ablation and deformation, and extends its service life.
Excellent thermal insulation properties:insulating fire brick for forge have low thermal conductivity, which can effectively isolate heat transfer inside and outside the furnace and improve energy utilization efficiency. At the same time, it can reduce the temperature rise of the outer wall, protect the furnace structure and reduce heat radiation loss.
Application of insulating fire brick for forge
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.
