  • Method of and device for controlling and cooling of a continuous rolled member, e.g. a wire
    Patent number: 4427463
    Abstract: The temperature of hot-rolled wire is controlled by passing the wire through a primary coil and a secondary coil continuously while energizing the primary coil with a high frequency alternating current (preferably 100 kHz) so that a temperature-control voltage is induced in the secondary coil. The secondary coil is connected to a comparator receiving a setpoint signal representing the desired temperature and the error signal from the comparator is fed via a temperature controller to the coolant control valve of the cooling stretch.
