Common unshaped refractory materials

People literally understand unshaped refractory materials, that is, refractory products that do not have a fixed shape like standard brick refractory bricks. There is no clear distinction between shape and type in a typed or literal sense.

Common unshaped refractory materials are: castables, refractory mud, refractory cement, refractory soil, etc. What they all have in common is that they are all powdered and have no fixed shape. They can be applied to the surface of the kiln, where it can fill gaps in the masonry.

What are the characteristics of amorphous refractory materials?

Wet, semi-wet or dry materials consisting of refractory aggregates (aggregates and powders) of a certain particle size, binders and additives that can be directly used in the construction or repair of industrial kiln linings are called unshaped refractory materials. Unlike sintered refractory products, the lining of this material can form a seamless overall lining, so it is also called seamless refractory material or integral refractory material in Europe and the United States. Because the preparation process and construction methods of this material are similar to ordinary building concrete, it is also called refractory concrete in Eastern Europe and Russia.

Its characteristics are:

1. Simple preparation process, short production cycle and high productivity.
2. It has strong adaptability and is not limited by the structural shape of industrial furnaces when used. It can be made into any shape:
3. It has good integrity, good air tightness and large thermal resistance, which can reduce the heat loss of industrial furnaces and save energy.
4. Mechanized construction is convenient, saving labor and time.
5. Prevent damage to the industrial furnace lining. It can be easily repaired with amorphous refractory materials, which can extend the service life of the lining and reduce the consumption of refractory materials.
