Abstract
Procédé pour réparer à chaud des revêtements réfractaires. On applique une première couche sur le revêtement à réparer d'une masse réfractaire bien adhérente et à forte teneur en grains fins et en liant et on applique ensuite une deuxième couche d'une masse réfractaire frittable et résistant à l'usure. Fours à flamme, convertisseurs, fours électriques, poches de coulée, fours de verreries et analogues.
