A system is disclosed for controlling the tension in rod or bar products being rolled continuously in first and second roll stands independently driven by drive motors. A first surface velocity gauge is positioned at the delivery side of the first roll stand and a second surface velocity gauge is positioned at the entry side of the second roll stand. The first and second gauges are operative, respectively, to continuously measure and generate control signals representative of the exit surface velocity of the product exiting the first roll stand and the entry surface velocity of the product entering the second roll stand. Separately operable controllers are provided for varying the operating speeds of the roll stand drive motors. A data processor operates in response to the control signals generated by the velocity said gauges to determine in real time the differential between the product exit and entry surface velocities, and to generate command signals to the speed controller unit of at least one drive motor to vary the operating speed of that drive motor in order to maintain the differential between the product exit and entry surface velocities within a desired range.
A system for controlling the tension in rod or bar products being rolled continuously in first and second roll stands, said roll stands being independently driven by drive motors, said system comprising:
A method of controlling the tension in rod or bar produce being rolled continuously in first and second independently driven roll stands, said roll stands having separately controllable operating speeds, said method comprising:
