Insulating Castables Can Be Applied To Kilns To Save Energy

Insulating Castable Refractory

Insulating castable is the refractory castable with low bulk density, high porosity and sound insulating performance in Rongsheng refractory materials manufacturer. Insulating castables is made of high quality aggregate, superfine powder, and several additives. It is also called light weight insulation castable which has a series of features such as light weight, high refractory temperature, low thermal conductivity, low water absorption, easy for construction and so on.

For its good performance, light weight insulation castable refractory is widely used in industrial field, such as metallurgy, machinery, electricity petroleum and other industries. It can be used as the thermal insulating layer of the linings and heat equipment alike, which can lower the heat consumption of industrial kiln and decrease the weight of kiln lining.

Description of the Insulating Castable

Insulating castable is refractory with light weight and high porosity. Insulating castable properties are mainly decided by its composition. Some light weight refractory materials are added into the this castable, therefore insulating castable refractory density is low, about 1.5 g/cm3. In addition, light weight insulation castable material has high cold crushing strength, and thermal insulation. With good workability, strong cohesion, it can be easily constructed. Insulating castable has strong impermeability, which is easy for the forming of dense and full seam and improve the air tightness, integrate of the inner wall of the chimney.

Light weight insulation castable material can be used in petroleum, construction, steel industrial and other industries. It can be used on the lining of the kiln and furnace, as overall casting material on the upper cover, and also it can be cast into precast blocks used on furnace door.

Types of Insulating Castable

According to refractory temperature, light weight insulation castable refractory can be divided to be low temperature insulating castable, medium temperature insulating castable and high temperature insulating castable refractory. These insulating castables have different service temperature, such as the first one is 600-900℃, the second is 900-1200℃, and the last one is over 1200℃.
