Abstract
PURPOSE: To improve the accuracy of a strip steel cutting operation in a strip steel rolling line, by predicting the strip cutting timing through detection of the number of pulses produced from a pulse generator interconnected to a roller turning shaft by the time when the top of material to be cut comes to a cutting point.
CONSTITUTION: A dividing shear 3 for cutting the strip steel 1 is disposed on the downstream side of the final mill 2, and material detectors D1, D2WDi, Di+1 are disposed at positions spaced from the shear 3 through a distance a little short of a required cutting length. In cutting the material into required sizes, counting of pulses produced from pulse generator 4 is started when the top of strip 1 passes detector Di-1 disposed on the upstream side of point P where the top of trip 1 is to be located at the time of cutting. Here, the moving speed of material 1 is detected from the count of pulses produced by the time when the top of material 1 passes detector Di, and a predicted number of pulses required for obtaining correct cutting timing is calculated by an arithmetic means 10. With such an arrangement, the shear 3 is set into operation when the pulse number after passing detector Di has reached the predicted pulse number.
