What are the classifications of refractory castables?
Refractory pouring material is a type of amorphous refractory material, also known as pouring material due to its pouring construction method. Refractory casting materials are easy to construct and have good integrity. They can be used for lining various industrial kilns and can also be used to manufacture prefabricated components.
Introduction to Types of Refractory Castable
1. According to their chemical properties, they are divided into acid resistant castables, neutral castables, and alkali resistant castables.
2. According to the composition of the binder, it can be divided into organic bonded castables and inorganic bonded castables, such as resin bonded castables and cement bonded castables.
3. According to the selected bonding method, it can be divided into: hydraulic bonding castable, gas bonding castable, thermal bonding castable, and ceramic bonding castable.
4. According to density, it can be divided into lightweight castable and heavy castable.
5. According to the refractory materials, they are mainly divided into different refractory materials such as clay castable, high alumina castable, siliceous castable, mullite castable, corundum castable, magnesium castable, silicon carbide castable, etc.
6. According to its characteristics, it is divided into various refractory castables with characteristics, such as high-strength wear-resistant castables, high-temperature resistant castables, low cement castables, steel fiber castables, acid and heat resistant castables, slag and wear-resistant castables, etc.
The classification of different dimensions and the types of refractory castables are different, and the applicable industrial kiln environment is also different. For example, aluminum magnesium castables are used for steel ladle and aluminum carbide silicon carbon castables are used for blast furnace tapping channel. The castables have a wide range of applications, and suitable fire-resistant castables can be selected based on the industrial kiln environment.
