Product description
Refractory castable concrete was also called refractory castables. The production process of refractory castable concrete is simple, labor-saving and energy-saving, with high construction efficiency and good quality. It can be prepared on site or materials with excellent performance can be selected as needed. Therefore, refractory castable is an unshaped refractory material that is used in large amounts and has a wide range of applications in furnace construction projects.
Application of refractory castable concrete :
Refractory castables are used in various heating furnaces, soaking furnaces, circulating fluidized bed boilers, waste incinerators, waste heat power generation boilers, hot blast furnaces, continuous casting tundish, hot metal tanks and tapping troughs, etc.
