Plastic Refractory Castable

The plastic refractory castable is flexible to use. In the application, you can install the plastic castable in plastic state. It also has wide applications as well as excellent properties. If you’re looking for high quality plastic refractory castable, Haoze Refractory is confident to meet your demands.

Main compositions of refractory plastic castable are powdery materials combined with binders such as plastic clay and plasticizers. Additionally, customers may add a small amount of water to form a hard mud paste that maintains high plasticity for a long period of time.Plastic clay is an important part of plastic refractories. Although it only accounts for 10% to 25% of the total amount of plastics, it has a great influence on the bonding strength of plastics and their hardened bodies, the plasticity of plastics and the volume stability and fire resistance of hardened bodies. In a certain sense, it can be considered that the nature and quantity of clay determine the nature of plasticity.

Parameters of Plastic Refractory Castable

Granular and powdery materials are the main components of plastic refractory, which accounts for 70% to 85% of the total weight. They come from all kinds of refractory materials. Therefore, you can classify the plastic refractory castable according to the material. Since this kind of castable is mainly used in various heating furnaces that are not directly in contact with the melt, clay clinker and high-alumina clinker are generally used. Light granular materials can be used to make lightweight refractory castable . Sometimes for some special requirements, silica, sintered and fused corundum, chromium, silicon carbide, zircon and carbonaceous materials can also be used.
