Castable
Castable, also known as refractory castable, is a granular and powdery material made by adding a quantitative binder to refractory materials. It has high fluidity and is formed by casting as an amorphous refractory material.
Application
The castable can be used in a wide range of applications, and the materials and binder can be selected according to the conditions of use. lt can be used for casting directly into lining, and can be made into prefabricated blocks by pouring or vibrating. lt is suitable for high temperature areas with small friction, such as the bottom air chamber of boiler, primary ar duct, feed back riser ( material leg), tail flue furnace wall, slag cooler, filling of each furnace door, etc.
