The SM type lining paste developed by the Carbon Division is mainly used for the tap hole and the guide trough, and can also be used for the repair of the tap hole. Lining paste for the tap hole and the guide trough;
Good oxidation resistance;
More suitable for FeMn and SiMn manufacturers;
Compared with traditional carbonaceous paste, SM cold rammed lining paste has a longer service life due to its enhanced anti-oxidation performance and is easy to install.
