Clay Bonded High Alumina Castable Refractory

September 17, 2018

Clay bonded high alumina castable refractory

Clay-cast refractories are widely used in the industrial field due to their good fire resistance and unformed characteristics.

The clay bonded high alumina castable refractory is based on high-aluminum aggregate, and clay is the binder. As one of the overall refractory materials, it is widely used in furnace walls and furnaces of heat treatment equipment such as heating furnaces and soaking furnaces.

The advantages of Clay bonded high alumina castable refractories are many:

(1) As an amorphous refractory material, it is easy to apply.

(2) More importantly, it can be applied to harsh conditions, saving energy and manpower.

(3) In addition, it has good structural properties and is beneficial to the service life of the lining.
