<p>PURPOSE:To control the sheet gauge so as to be aimed thickness independently of the delay of detection, the delay of the screw-down-position-controlling-system, etc., by controlling depending on the deviation data for the sheet gauge read out of the memory by the timing device. CONSTITUTION:The pulse of the pulse oscillator 11 is sent to the sheet-gauge-deviation-memory-and-timing-unit 12 correspondingly to the rotation of the mill, and the oscillated pulse N1 since the time of lodk-on is counted. The sheet-gauge-deviation DELTAh is computed for every pulse N1, and is memorized successively in the sheet- gauge- deviation-memory 14. Next, in the case of delivery into the reverse rolling direction, the sheet-gauge-deviation-output-timing-device 13 settles the timing for inputting the deviation data memorized in the memory 14 for every pulse N1 into the screw controller 16. When the pulse count after the lock-on becomes Nn, the sheet- gauge- deviation memorized in the memory 14 as the pulse count Nn at the former rolling pass is derived.</p> |
