A method for repairing industrial facilities at high temperatures using at least one prefabricated element (1) made of a mullite-crystallised refractory product with an alumina content of 30-85 %, preferably 50-80 %, made of refractory materials securely attached to the structure (11) of the facility by using an oxygen-containing carrier gas stream to spray a mixture of particles capable of exothermically reacting with the oxygen and particles of a refractory material, whereby a coherent refractory mass (14) is formed in situ for attaching said element to said structure.
L'invention est relative à un procédé de réparation à chaud d'installations industrielles suivant lequel on fait usage d'au moins un élément préfabriqué (1) en un produit réfractaire à crittallisation mullitique présentant une teneur en alumine comprise entre 30 et 85 % et de préférence entre 50 et 80 % d'alumine, en matériaux réfractaires que l'on solidarise avec la structure (11) de l'installation par la projection, au moyen d'un courant de gaz porteur contenant de l'oxygène, d'un mélange de particules pouvant réagir exothermiquement avec l'oxygene et de particules d'une matière réfractaire, de manière à former in situ une masse réfractaire cohérente (14) permettant de fixer l'élément susdit à la structure susdite,
