What are the Advantages of Plastic Refractory Castable?

Strong Plasticity
High Compressive Strength
Good Corrosion Resistance
Great Wear Resistance
Excellent Thermal Shock Resistance

Excellent Construction Performance

The castable plastic has high fluidity and plasticity. As a result, customers can apply via vibration, spraying and pumping. It can adapt to complex shapes and curved surface structures, improve construction efficiency and reduce labor costs.

Good Adhesion and Compactness

Kerui refractory plastic can bond well with base materials during the construction process to form a solid overall structure. At the same time, plastic refractory castables have high compactness. It can fill small gaps and provide better thermal conductivity.

Excellent Heat Resistance

Like refractory firebricks, plastic refractory castable uses high-temperature stable refractory materials as the main component. So, it has excellent high temp resistance. It can maintain structural stability and integrity in high temperature environments.

Energy Saving and Environmental Protection

The construction process of plastic refractory castable does not require high-temperature sintering. This saves energy and reduces environmental pollution. In other words, its production and use processes are more environmentally sustainable.

In Which Industrial Furnaces and Kilns Are Plastic Refractory Castable Used?

Heating Furnace

We often use plastic refractory castable for the top part of the heating furnace. Such as stove top and combustion chamber roof. It can withstand high temperatures and thermal shock. So, it protects the furnace roof structure from thermal expansion and thermal shock.

Cement Rotary Kiln

Plastic refractory is often used in the installation of fire cement rotary kiln firing areas. Such as kiln head, kiln tail and kiln shell. Moreover, it can withstand high temperatures and chemical corrosion. This means that the kiln shell will not be damaged by a chemical attack.


You can also use Plastic refractory castable in different parts of the boiler. Such as furnace, combustion chamber, flue and burner nozzle. It can withstand thermal stress. Therefore, the boiler structure is not affected by thermal expansion, combustion and flue gas erosion.

Other Industrial Kilns

Customers can also use Kerui high quality high temp castable refractory in a wide range of applications in other industrial kilns. Such as glass kilns, ceramic kilns and steel smelting furnaces. With it, we can avoid the kiln structure affected by chemical attacks and material wear.
