Refractory Castable
MOQ: 5 tons
Description
Refractory Castable has high fluidity and is suitable for construction by casting method. It is an unshaped refractory that can be hardened without heating. The refractoriness is similar to that of refractory bricks of the same texture, the load softening point is slightly lower than that of refractory bricks, and the overall performance is better than refractory bricks. The castable has higher compressive strength at room temperature due to the effect of low temperature on the binder. Due to the good integrity of the masonry, the airtightness of the blast furnace is good, it is not easy to be deformed, and its resistance to machine vibration and impact is better than that of brick masonry.
Features
The main features of refractory castable is its ability to withstand high temperatures. The material can resist temperatures of up to 1800°C, making it ideal for use in applications where extreme heat is a concern. In addition to its high-temperature resistance. It is also highly durable and resistant to wear and tear. This means that it can provide excellent performance over a long period of time, even in harsh environments.
Another advantage is its versatility. The material can be customized to meet specific application requirements, with different aggregate and binder combinations available to provide different levels of strength, durability, and thermal resistance. This flexibility makes it easy to find the right refractory castable for any application.
Application
Refractory Castable is currently the most widely produced and used unshaped refractory. It is mainly used to form integral structures such as linings of various heating furnaces. Compared with other amorphous refractories, the binder and moisture content of castable is higher, and the fluidity is better. Therefore, the application range of castable is wider, and the material and binder can be selected according to the conditions of use. It can be directly cast into the lining for use, or made into prefabricated blocks by casting or shaking method.
