Abstract

LE PROCEDE DE L'INVENTION EST APPLICABLE A LA SORTIE D'UN LAMINOIR A CHAUD, DANS LEQUEL ON EMET DES FAISCEAUX OPTIQUES EN DIRECTION DE LA FIBRE CENTRALE ET DES RIVES DE LA TOLE, PUIS UNE PARTIE DU RAYONNEMENT OPTIQUE RETRANSMIS PAR LA TOLE ETANT CAPTEE, ON CALCULE LES NIVEAUX DE CES POINTS PAR RAPPORT A UN PLAN HORIZONTAL DE REFERENCE A L'AIDE DE TRIANGULATIONS OPTIQUES ET ON DETERMINE UN INDICE DE PLANEITE EXPRIMANT L'ALLONGEMENT DIFFERENTIEL DES FIBRES SCRUTEES. IL EST CARACTERISE EN CE QUE L'ON POSITIONNE LES FAISCEAUX EMIS ET LES AXES OPTIQUES DES APPAREILS RECEPTEURS AU MOYEN DE DEFLECTEURS ORIENTABLES 18, 29, 30, 31, 32, 38, 39, 40, 45, 46 ET 47 POUR QUE LES POINTS D'IMPACT 21, 22, 43 ET 44 DE CES FAISCEAUX SE SITUENT AUX ENDROITS VOULUS DE LA TOLE, QUELLE QUE SOIT LA LARGEUR DE CETTE TOLE.
