  • a calculation of the heat flow to be dissipated or a quantity of coolant required for this purpose can generally be adiabatic on one side, ie the calculation with respect to one side, for example the top side, does not have to take into account the interaction with the other side, for example the underside of the metal sheet.
  • first sheet and two ⁇ tes sheet is advantageously proceeded such that in each case an individual, in particular temporal, course of an energetic state of the sheet descriptive size is determined for the first sheet and the second sheet on ⁇ hand whose a dissipated heat flow for each sheet top and bottom of the sheet is determined.
  • a variable describing the energetic state it is possible, for example, to use a, in particular calculated, actual temperature profile, actual enthalpy curve or a course of another suitable variable.

  • the coolant quantities for the coolant delivery device can be determined above the metal sheet and below the metal sheet for the respective pair of coolant devices. This takes place in a method step 104. If, for example, a flat sheet enters the cooling section, then the heat flow is set in such a way that the same heat flow is dissipated from the top side of the sheet metal and the underside of the sheet, taking into account the different temperatures of the top side of the sheet metal. This fact, since the temperature of sheet metal top and tin bottom is generally governed differently, a change in the amounts of refrigerant for the arranged above the sheetdeffenabgabeein ⁇ direction and for the underneath of the sheet arranged cooling ⁇ agent release device as compared with the prior art determined quantities of coolant. However, uniform cooling is only possible if the heat flow on the upper side of the sheet metal and the underside of the sheet is the same, which is achieved by a procedure according to one of the embodiments of the method according to the invention.

Abstract

L'invention concerne une branche de refroidissement, un dispositif de contrôle et/ou de régulation pour une branche de refroidissement, un code de programme lisible par machine, un support d'enregistrement et un procédé de refroidissement d'une tôle au moyen d'une branche de refroidissement. Selon l'invention, la branche de refroidissement présente une pluralité de dispositifs de délivrance d'un fluide de refroidissement destinés à refroidir un côté supérieur de tôle et une pluralité de dispositifs de délivrance d'un fluide de refroidissement destinés à refroidir un côté inférieur de tôle, et un état cible prédéfini de la tôle est atteint au moyen du refroidissement en un point de référence lors de la sortie de la branche de refroidissement et/ou après celle-ci. Toujours selon l'invention, une délivrance de fluide de refroidissement est déterminée pour un premier et un deuxième dispositif de délivrance de fluide de refroidissement et le premier et le deuxième dispositif de délivrance de fluide de refroidissement sont disposés en opposition l'un de l'autre par rapport à la tôle. En déterminant la délivrance de fluide de refroidissement pour le premier et le deuxième dispositif de délivrance de fluide de refroidissement (2) au moyen d'un flux calorifique prédéfini à évacuer du côté de la tôle (O, U) qui fait face au dispositif de délivrance de fluide de refroidissement (2) correspondant, une température, notamment la température de surface (To, Tu) du côté correspondant de la tôle (O, U) étant prise en compte pour le flux calorifique respectif à évacuer, il est possible d'accroître davantage la planéité de la tôle brute produite tout en assurant un débit élevé de la ligne de tôle brute.
