Abstract
PURPOSE: To accurately measure the length of divided coil regardless of the slip between the coil and a roller table by measuring the fore and aft crop lengths at the front and the rear of hot dividing machines and correcting the measured values by the length of the crop before divided.
CONSTITUTION: When a load relay 9 produces an OFF signal and a cam limiter produces an ON signal (a signal representing that a drum revolved passes a lower dead point) in the state that a coil detector 3 become ON, a CPU 10 judges it as an end crop breakage to calculate the end crop length. If the three detectors all become ON after restarted, the CPU 10 sequentially detects the divided length as production of divided hot rolled coil. When the coil detector is turned off, the CPU 10 calculates the residual coil length and obtains the hot divided last coil length and the rear end crop length as the rear crop breakage at the time when the cam limiter is turned off to correct the respective divided coil lengths by the length under the respective states to be obtained the calculation.
