Application:
ladle castable generally has a high normal temperature strength, can be made into prefabricated parts in the kiln spinning site installation, such as continuous casting in the middle of the filling with fire-resistant weir plate prefabricated installation, refractory castable is mainly used in metallurgical industry stoves, but also in petroleum, chemical, building materials, electric power and machinery industry kiln and thermal equipment widely used. In addition, it is also suitable for the working lining of ordinary ladle, refining ladle, and electric furnace ladle.
