Description

Low Creep Clay Firebrick is made of compact structure high -quality chamotte powder with less impurities as the main raw material.New fireproof raw material and additive binder are added. Clay refractory brick is formed high temperature sintering proportionally propotioned mixing,high pressure molding and high temperature sintering.

Low Creep Clay Bricks Characteristic

Low creep rate and small high temperature creep

The load softening temperature is high

Good impact resistance

High temperature compression strength

High temperature volume stability and wear resistance.

Good erosion resistance.

Low Creep Clay Firebrick Application

Low Creep Clay Refractory Brick can be used in the hot air furnace of medium ,such as the lower wall and the lower grid brick of the regenerator. Low creep clay firebrick can be used in the furnace cupola furnace heating furnace coke oven and other thermal equipment.
