  • the width of the belt is divided into cooling zones and the cooling zones is assigned a temperature.
  • the cooling method evaluates the available data and determines, depending on the input variables and with the knowledge of the cooling effect, which nozzles are activated or deactivated and which coolant quantity is to be adjusted at which nozzle, so that a substantially homogeneous temperature distribution results.
