Abstract

A.DISPOSITIF POUR DETECTER LE NIVEAU DE LA SURFACE D'UN METAL EN FUSION. B.CE DISPOSITIF DE DETECTION UTILISE UNE CAMERA DE TELEVISION INSTALLEE A UN EMPLACEMENT APPROPRIE OU ELLE N'EST PAS AFFECTEE PAR LA CHALEUR DU METAL EN FUSION ET OU ELLE NE GENE PAS LE TRAVAIL. CETTE CAMERA PHOTOGRAPHIE LA SURFACE DU METAL EN FUSION SUIVANT UNE DIRECTION PERMETTANT DE SURVEILLER SON NIVEAU, L'IMAGE AINSI PHOTOGRAPHIEE DE LA SURFACE DU METAL EN FUSION ETANT TRAITEE D'UNE MANIERE APPROPRIEE POUR DETERMINER AVEC PRECISION ET DE MANIERE FIABLE LE NIVEAU DE SA SURFACE. C.METALLURGIE DU CUIVRE ET DE L'ALUMINIUM.A. DEVICE TO DETECT THE SURFACE LEVEL OF A MELTED METAL. B. THIS DETECTION DEVICE USES A TELEVISION CAMERA INSTALLED IN AN APPROPRIATE LOCATION WHERE IT IS NOT AFFECTED BY THE HEAT OF THE MELTED METAL OR IT WILL NOT HARM WORK. THIS CAMERA PHOTOGRAPHS THE SURFACE OF THE MELTING METAL FOLLOWING A DIRECTION TO MONITOR ITS LEVEL, THE IMAGE THUS PHOTOGRAPHED OF THE SURFACE OF THE MELTING METAL BEING PROCESSED IN AN APPROPRIATE MANNER TO DETERMINE THE LEVEL WITH ACCURACY AND RELIABLY. . C. METALLURGY OF COPPER AND ALUMINUM.
