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, super fine powder, and several additives. It is also called lightweight insulation castable which has a series of features such as lightweight, high refractory temperature, low thermal conductivity, low water absorption, ease for construction, and so on.
For its good performance, lightweight insulation castable refractory is widely used in the industrial fields, 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 lightweight and high porosity. Insulating castable properties are mainly decided by its composition. Some lightweight refractory materials are added into this castable, therefore insulating castable refractory density is low, about 1.5 g/cm3. In addition, lightweight insulation castable material has a 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 the dense and full seam and improves the airtightness, integrates of the inner wall of the chimney.
Lightweight insulation castable material can be used in petroleum, construction, steel industry, 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 the furnace door.
Types of Insulating Castable
According to refractory temperature, lightweight 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 temperatures, such as the first one is 600-900℃, the second is 900-1200℃, and the last one is over 1200℃.

Advantages of Insulating Castable
- Energy Saving & Manpower Saving: Insulating castable is usually mixed with a certain percentage before construction.
- Suitable for Harsh Condition & Easy for Construction: Insulating castable is unshaped refractory, so it can meet various construction conditions.
- Heat Resistance & Wear and Shock Resistance
