COATING MASS, DRY MATTER COMPOSITION AND METHOD FOR APPLYING A COATING MASS

摘要

The invention relates to a coating mass to be used as a coating material for coating the surfaces of vessels that come in contact with molten metal, the coating mass containing a dry matter composition containing a fire-resistant aggregate mixture and a binder, and wa­ter which has been added to the dry matter composition when applying the coating material. According to the invention, the coating mass contains less than 10 w-% of water calculated from the weight of the coating mass, and that the dry matter composition mainly con­sists of non-organic components and the dry matter composition contains, calculated from the weight of the dry matter composition, as the main binder 1-3 w-% of dry magnesium sulphate, less than 7 w-% of auxil­iary binders, which contain hexametaphosphate, calcium silicates, calcium aluminates, anhydrous calcium sul­phate and/or resin, less than 6 w-% of cyanite as an additive, and 85-93 w-% of non-organic aggregate or an aggregate mixture. Further, the invention relates to a method for arranging the coating mass as a coating ma­terial.
