Application
Ladle castables generally have high normal temperature strength, and can be made into prefabricated parts and installed at the kiln turning site, such as the installation of prefabricated refractory weir plates for intermediate irrigation in continuous casting. Refractory castables are mainly used in metallurgical industrial stoves , It is also widely used in kilns and thermal equipment in petroleum, chemical, building materials, electric power and mechanical industries. In addition, it is also suitable for the working lining of ordinary ladles, refining ladles, and electric furnace ladles.
