Product description
Insulating fire bricks k23: refers to the aluminum content of 30%-46% light firebrick, with clay clinker or light clinker and plastic clay as the main raw material, using combustible method production. The bulk density is 0.75-1.20g/cm3, the compressive strength is 2.0-5.9MPa, the thermal conductivity is 0.221-0.442W (m.k), the service temperature is 1200-1400℃, used for various industrial furnaces do not contact the melt and no corrosive gas action of the heat insulation layer material.
Advantages of insulating fire bricks k23:
Insulating fire bricks k23 can resist acid and alkali corrosion and metal oxide corrosion. It is suitable for various industrial environments and can ensure the integrity and stability of the furnace structure.
Application of insulating fire bricks k23
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.
