Title (EN) METHOD OF TORCH GUNITE OF LININGS OF METALLURGICAL INSTALLATIONS
(FR) METHODE DE REVETEMENT PAR TORCHE GUNITE D"INSTALLATIONS METALLURGIQUES
Abstract: front page image
(EN)A method of torch gunite of linings of metallurgical installations comprises supplying a mixture of a refractory material and a fuel, in the form of a central axially simmetrical jet, and the oxigen, in the form of an annular jet, coaxial to the jet of the mixture of the refractory material and the fuel, heating and partial melting of the refractory material inside the high temperature torch and applying the refractory material to the lining surface, the oxigen being supplied in the form of an annular narrowing jet twisted around its own axis with the ratio of that twisting impulse of the oxigen jet to the impulse of the jet of the refractory material and the fuel being equal to 0.3 to 3.0.
(FR)Une methode de revetement par torche a gunite d"installations metallurgiques consiste a envoyer un melange d"un materiau refractaire et d"un combustible sous forme d"un jet central axialement symetrique et l"oxygene sous forme d"un jet annulaire coaxial au jet du melange du materiau refractaire et du combustible a chauffer et faire fondre partiellement le materiau refractaire a l"interieur de la torche a temperature elevee et appliquer le materiau refractaire sur la surface de garniture, l"oxygene etant envoye sous forme d"un jet annulaire retrecissant varie autour de son propre axe, le rapport de cette impulsion de torsion du jet d"oxygene par rapport a l"impulsion du jet de materiau refractaire et de combustible etant de 0,3 a 3,0.
