Abstract

PURPOSE:To make the smooth, stable sheet pass condition possible to be maintained without trouble such as the slip, etc., by first starting the control of the interstand tension of the material to be continuously rolled by the plural stands, with a small sheet-pass aim value, and hereafter, by gradually increasing this aim value to the ordinary aim value. CONSTITUTION:The tip of the steel sheet 10 as the rolled material passes the (i-1)th stand 11 and arrives at the i-th stand 12; at this point, the detector 16 detects the biting and the roll 24 detects the tension between two stands 11, 12. The aim operator 22 starts the operation according to the signal 17, the relay 42 is closed, and the deviation of the actually measured tension Ti from the sheet-pass aim value inversion Ti, to be operated by the deviation operator 36, is inputted to the tension controller 38. The controller 38 carries out the PI compensation, etc., in order to stably control the tension for both of high and low speeds, and inputs the optimum aim value for the circumferential speed VRi-1 of the stand 11 to the automatic speed controller 32. The speed controller 32 carries out the gain compensation, etc., and controls the speed of the motor 28 to be detected by the pilot generator 30 in order to make the circumferential speed VRi-1 appropriate, and to make the tension between the stands 11, 12, to coincide with the aim value.
