Abstract
PURPOSE: To control the sheet thickness, by obtaining the deviation of sheet thickness detected on the run-out side of the downstream mill from the set point of sheet thickness, and by altering the speed difference between upper and lower rolls of the downstream mill or between upper and lower rolls of upsteam and downstream mills, correspondingly to above obtained thickness deviation.
CONSTITUTION: The thickness gauge 16 detects the sheet thickness on the run-out side of upper and lower rolling rolls 4, 3. Then, the thickness control circuit 17 produces a signal for correcting the thickness correspondingly to the deviation of above detected sheet thickness from the value of sheet thickness set in the thickness setting circuit 18. Hereupon, if this thickness correction signal is an allowable range of speed difference between upper and lower rolls, the thickness control output distribution circuit 19 produces the thickness correction signal as the correction signal for the speed difference of the upper roll 4. If the thickness correction signal is above the limit range of the upper and lower rolls' speed difference, the thickness correction signal is produced as the speed difference correction signal for the upper roll 4, and the excess above the upper limit of allowable range is produced as the speed difference corection signal for the lower roll 3 and the upper roll 4.
