Abstract

Une cuillere pour torche a gunite comprend un corps refroidi a l'eau constitue de deux cubes (1 et 2). A l'interieur du corps refroidi a l'eau sont montees des canalisations coaxiales (4) d'alimentation en un melange pulverulent d'un materiau refractaire et en un combustible, et des canalisations (3) d'alimentation en oxygene. Aux extremites de sortie des canalisations (3 et 4) sont montes, le long de leur paroi, des ajutages (5) pour l'alimentation en melange pulverulent en materiaux refractaires et en combustibles et des ajutages (6) pour l'alimentation en oxygene, ces ajutages etant combines par paire et situes coaxialement dans chaque paire. La face de chaque ajutage (5) d'alimentation en melange pulverulent de materiau refractaire et en combustible est placee sous la face de chaque ajutage correspondant (6) d'alimentation en oxygene a une distance de 1 a 5 fois le diametre interne de l'ajutage (5) d'alimentation en melange pulverulent de materiaux refractaires et en combustibles. Des parois d'au moins un ajutage (5 ou 6) pour chaque paire ont, entierement ou partiellement, une forme differente de celle d'un cylindre.
