Abstract

Procédé de contrôle de la température d'un ruban de verre flotté (1) sur un bain métallique fondu (5) d'une ligne de production de verre plat par l'utilisation d'unités radiatives à l'intérieur de l'espace fermé au-dessus du bain pour le refroidissement du ruban de verre, procédé selon lequel : on fait circuler un fluide gazeux dans les unités radiatives (13) de contrôle de la température du ruban de verre ; on utilise les unités radiatives à l'intérieur dudit espace fermé non seulement pour absorber un rayonnement thermique avec le verre et son environnement pour son refroidissement, mais aussi pour émettre un rayonnement thermique et assurer un chauffage du verre; et on définit l'intensité de l'échange thermique entre chaque unité radiative et le ruban de verre en chaque point de la longueur du bain de façon à obtenir la courbe de température souhaitée.Method of controlling the temperature of a ribbon of float glass (1) on a molten metal bath (5) of a flat glass production line by the use of radiative units inside the closed space above the bath for cooling the glass ribbon, method according to which: a gaseous fluid is circulated in the radiative units (13) for controlling the temperature of the glass ribbon; the radiative units are used inside said closed space not only to absorb thermal radiation with the glass and its environment for its cooling, but also to emit thermal radiation and ensure heating of the glass; and the intensity of the heat exchange between each radiative unit and the glass ribbon at each point along the length of the bath is defined so as to obtain the desired temperature curve.
