Abstract
A refractory furnace wall coating composition having melting and decomposition temperatures > 2700 DEG F. comprises: (a) a glass batch molten at 1400-2400 DEG F. containing CaF2, SiO2, CaO, Na2CO3 and Na2F or Na2SiF6; (b) Na2SiO3 or K2SiO3; and (c) SiC, molybdenum carbide, or graphite, and optionally Al2O3. The composition comprises by weight about 1 part (a): 1 part (b): 6 parts (c). The Al2O3 may be added as Al powder. The powdered materials are mixed and added to an equal volume of water with stirring, and are used or stored after gas has evolved. The coating material is stirred and 20% vol. water added with stirring. The coating is then applied to the cleaned surface, dried and fired. A second coating may be applied before firing. The coating can then withstand temperatures of 3400-3600 DEG F., i.e. 300 DEG F. higher than the fusion temperature of the refractory batch to which the coating has been applied. The coating materials on firing react with the refractory surface materials.ALSO:A refractory furnace wall coating composition having melting and decomposition temperatures > 2700 DEG F. comprises: (a) a glass batch molten at 1400 DEG -2400 DEG F. containing CaF2, SiO2, CaO, Na2CO3 and Na2F or Na 2SiF6; (b) Ma2SiO3 or K2SiO3; and (c) SiC, molybdenum carbide, or graphite, and optionally Al2O3.
