Low creep clay refractory brick is made of high quality pyrotechnical refractory raw material with less impurities, compact structure and high purity. It is added with new refractory raw materials, additives and binders, refractory brick is formulated by high-temperature sintering after compounding, mixing and high-pressure molding. It has the advantages of small creep rate and strong heat storage capacity.
Therefore, the raw materials for producing low creep clay bricks must be dense in structure, high in purity, and low in impurities, so as to avoid excessive liquid phase in the product during firing to reduce creep resistance and increase heat resistance of low creep clay bricks. Shock and erosion resistance
Low Creep Clay Fire Brick Feature
1. The creep rate is low and the high temperature creep is small.
2. The load softening temperature is high.
3. Good impact resistance.
4. High temperature and compressive strength.
5. High temperature volume stability, good wear resistance.
6. Good resistance to erosion.

Low Creep Clay Refractory Brick Application
The low creeping clay refractory brick can be used for the hot blast stove of large, medium and small blast furnaces, and is mainly used for the low temperature parts of the hot blast stoves such as the middle and lower walls of the regenerator, the lower lattice bricks, etc.; it can also be used for blast furnaces, iron furnaces, heating furnaces and Thermal equipment such as coke ovens.
Why Choose Low Creep Fire Brick as Refractory Lining Material
The lower the creep rate of the low creep clay refractory brick, the smaller the deformation amount in the high temperature environment, and the better the stability of the lining as a thermal equipment.
