2. Foundries: Employed in casting pits, crucibles, and other high-temperature equipment.
3. Power Plants: Utilized in boilers, heat exchangers, and other components exposed to extreme heat.
4. Chemical Plants: Used in reactors, vessels, and pipelines that handle corrosive chemicals.
5. Glass Manufacturing: Applied in glass furnaces and other high-temperature processes.
6. Cement Plants: Employed in kiln linings, pre-heaters, and other critical areas.
Relationship between Refractory Plastic Castable Concrete and Gunning Type
Refractory plastic castable concrete and gunning refractory castable is both types of refractory materials that are used in high-temperature applications. However, there are some key differences between the two materials:
Composition: Refractory plastic castable concrete is typically made with a hydraulic binder, such as cement or a high-temperature resistant resin. Certainly, Gunningcastable is made with a dry mixture of refractory aggregates, binders, and additives.
Installation: Refractory plastic castable concrete is mixed with water and then poured into place. However, gunning refractory castables are applied using a specialized gunning machine.
Applications: Refractory plastic castable concrete is typically used in applications where a strong and durable refractory lining is required, while gunning refractory castables are typically used in applications where a quick and efficient installation is required.
