Patent

CA 2581162

A process, apparatus and material composition for forming a coherent refractory mass on a surface wherein one or more non-combustible materials are mixed with one or more metallic combustible powders and an oxidizer, igniting the mixture in a combustion chamber so that the combustible metallic particles react in a exothermic manner with the oxidizer and release sufficient heat to form a coherent mass of material under the action of the heat of combustion, and projecting this mass against the surface so that the mass adheres durably to the surface.

L'invention concerne un procédé, un dispositif et une composition de matière permettant de former une masse réfractaire cohérente sur une surface. Le procédé comporte les étapes consistant à: mélanger une ou plusieurs matières incombustibles avec une ou plusieurs poudres métalliques combustibles et un oxydant; allumer le mélange dans une chambre de combustion de sorte que les particules métalliques combustibles réagissent de manière exothermique avec l'oxydant et libèrent suffisamment de chaleur pour former une masse de matière cohérente sous l'effet de la chaleur de combustion; et projeter cette masse contre la surface de sorte que la masse adhère durablement à la surface.
