Abstract

Formation de masses réfractaires par projection d'un mélange de particules réfractaires et de particules oxydables exothermiquement, dans un gaz comburant, au moyen d'une lance (1) dont la tete (5) comporte plusieurs ajutages. Ces ajutages (15) forment un groupe qui délimite un polygone fictif et dans lequel les écartements entre ceux-ci et leurs premiers et seconds voisins ne dépassent pas une limite donnée. Le groupe d'ajutage projette les particules sous un débit supérieur à 50 kg/h cm2. L'invention convient à la réparation à chaud de surfaces importantes telles que des parois de fours ou d'autres équipements réfractaires.Formation of refractory masses by projection of a mixture of refractory particles and particles exothermically oxidizable, in an oxidizing gas, by means of a lance (1) whose head (5) comprises several nozzles. These nozzles (15) form a group which delimits a fictitious polygon and in which the spacings between these and their first and second neighbors do not exceed a given limit. The nozzle group projects the particles at a flow rate greater than 50 kg / h cm2. The invention is suitable for the hot repair of large surfaces such as oven walls or other refractory equipment.
