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.Process for hot repair of refractory linings. A first layer is applied to the coating to be repaired of a refractory mass which adheres well and has a high content of fine grains and is bonded, and then a second layer is applied of a refractory mass which is sinterable and resistant to wear. Flame furnaces, converters, electric furnaces, ladles, glass furnaces and the like.
