An electronic circuit for two-way measurement and control of the drive speed of consecutive roll installations of a continuous rolling strand completes the change in rotational movement of rolling stand rolls and adjusts the rotational speed accordingly as the material being rolled passes through. Sensors give a time based impulse to the circuitry as the rolled material passes them and this is combined with values from tachometers registering the rotation of D.C. drive motors. The rest of the circuitry is then combined of components to adjust the roll speed to compensate for alterations in turning movement due to the passage of the rolled material. |
