Title
(EN) ROLLER-HEARTH KILN FOR HEATING GLAZING SHEETS
(FR) FOUR A ROULEAUX POUR LE CHAUFFAGE DE VITRAGES
Abstract
(EN) The invention concerns a roller-hearth kiln for heating glazing sheets (6) to their softening temperature comprising, above the roller conveying means (3), vanes forming blow-pipes (12, 13) arranged transversely to the displacement direction of the glazing sheets (6) and designed to blow hot gas on the top surface of the glazing sheet, and beneath the roller conveying means (3), to provide exclusively heating by radiation (5).
(FR) Un four à rouleaux pour le chauffage de vitrages (6) à leur température de ramollissement est pourvu, au-dessus de la voie de transports à rouleaux (3), d'ailettes formant buses de soufflage (12, 13) disposées transversalement à la direction de déplacement des vitrages (6) et destinées à souffler du gaz chaud sur la surface supérieure du vitrage (6), et en dessous de la voie de transport à rouleaux (3), exclusivement d'un chauffage par rayonnement (5).
