What is the Composition of Refractory Castables

The composition of refractory castable is composed of refractory aggregate, refractory powder, additives and binder. What are the main components of refractory castables? The refractory castable is a mixture of powder particles composed of various aggregates and binders. It is an unshaped refractory material made by a variety of processes. If you know the specific composition of the refractory castable, you need to test it and understand its resistance. What are the main components of the castable (www.highaluminarefractory.com/high-alumina-castable/)? It can be determined according to the main components of the main refractory materials used.

The main component of refractory castable is the basic inspection of the physical and chemical indexes of refractory castable. In the composition analysis of refractory castables, we talked about the main components of refractory castables, namely the main body of refractory castables and the basic conditions that directly determine the fire resistance of refractory materials.

The composition of refractory castables can be divided into main components and auxiliary components. The basic component that accounts for a large proportion of the main role is called the main component, and the content of the raw material and the component added in the process are called the secondary component.

Such as high-alumina castables, the main component is alumina; such as silicon castables, the main component is silicon dioxide, which is acid-resistant and refractory castable; castable magnesium, the main component is magnesium oxide, and so on.

For example, aluminum-magnesium castables are mainly composed of alumina and magnesia, such as corundum mullite castables, which are mainly composed of alumina, but the content is relatively high. The main component is chemical composition, which plays a leading role in refractory castables and accounts for a large proportion in refractory castables. It has an important decision on the high temperature performance of refractory castables. Whether it can be used in high-temperature furnaces, the main components of refractory castables also have a great influence.

The main components of refractory castables are generally what the main components of refractory raw materials are selected, but strictly speaking, the main components of refractory castables are determined by testing equipment and detection values.
