METHOD AND CONTROL DEVICE FOR CONTROLLING THE HEAT REMOVAL FROM A SIDE PLATE OF A MOULD

摘要

The invention relates to a method and a control device for controlling th e heat removal q in the case of a mould 200 for the casting of metal. By sui table variation of the flow V of a cooling medium 300 through the side plate of a mould, heat removal from the side plate is adjusted to a predetermined setpoint value q Soll. In order not to have to adapt the control of the hea t removal to different thicknesses or coatings of the side plates every time that different moulds are used or to changed adjustments of the side plates during the casting operation or to different grades of steel that may be ca st, it is proposed according to the invention to calculate in real time the actual value for the heat removal q during stationary casting operation suit ably for the cooling medium in each case, inter alia from the difference bet ween the temperature of the cooling medium 300 at the coolant outlet and at the coolant inlet of the side plate 200 and also from material constants.
