Abstract

PURPOSE:To make possible tbe feed-forward control system to be constituted simply, and to improve the accuracy of the thickness control, by sampling the entry side thickness twice in the specified time of travel of the sheet material, on purpose to detect the deviation in the thickness of the sheet material just under the reducing roll, and by adjusting the roll gap depending on the above detected deviation. CONSTITUTION:The material B is continuously fed from the feed roll 12 to the reducing roll 10, and is rolled into the specified thickness before being coiled into the reel 14. In this constitution, the draft control system and the tension codntrol system are installed in the thickness controller; the speed signal generator 18 is directly connected to the motor 10 for driving the roll 10; the speed signal for the rolling line, being produced from the speed signal generator 18, is inputted to the voltage-frequency converter 20 whose output is sent to the sampling pulse circuit 22. In the meantime, the thickness meter 24 is installed on the entry side of the sheet material B, and the thickness signal of the meter 24 is inputted to the deviation amplifier 28 through the analog memory 26; the amplifier 28 cooperating with the circuit 22 controls the rotation of the screw motor 34. Besides, the thickness meter 36 is installed on the exit side of the sheet material B, and the thickness signal of the meter 36 controls the reel motor 40 through the tension controller 38. Hereby, the accuracy is improved by cooperation of the feedback control system and the feed- forward control system.
