Imerys covering compounds are available in granular or powder form and are sold under the brand name GLUTIN. The materials are engineered from various raw materials to obtain melting properties and chemical composition that meets the requirements of the process, and are designed to:
- Provide thermal insulation limiting heat-loss
- Prevent “skull” formation of steel in the ladle/tundish
- Prevent refractory wear to increase life of refractories and increased vessel life
- Prevent “bridging” between the wall and stopper in the tundish to ensure reliability of the process
- Prevent re-oxidation and absorb unwanted impurities from the steel
