Abstract

PURPOSE:To finely control the shape of the strip, by installing the controller for intermittently producing the shape correction signal depending on the signal being sent from the reference signal generator at carrying out the low speed rolling work. CONSTITUTION:If the segmental roller 8 receiving the load from the strip 2 causes a distortion, the gap between the segmental roller 8 and the sensor 15 changes. The value of this gap change is input from the sensor 15 to the operator 25 which converts it to the shape signal. This shape signal is memorized by the memory 26 only when the signal of the reference signal generator 27 is input to the memory 26. This memory signal enters into the controller 28 and is displayed on the monitor 29. The controller 28 operates the rolling speed from the signal of the tachometer 29; if the rolling speed is slower than the reference speed, the controller 28 intermittently produces the theoretical shape correction signal correspondingly to the signal sent from the reference signal generator 27. Whereas, if the rolling speed is faster than the reference speed, the controller 28 continuously produces the correction signal. The signal of the controller 28 enters into the controllers 30. 31 which respectively controlls the bending device and the balancing device, to perform the shape correction.
