<p>PURPOSE:To eliminate the error caused by the upper camber at the end part, etc. and to perform the control of a roll aperture having high reliability by correcting the measured value of a plate width by measuring either the upper camber quantity, floating quantity or plate thickness of the material to be rolled simultaneously at the same place as the plate with measurement. CONSTITUTION:The tip position of the material to be rolled released from the first horizontal rolling mill 1 is detected by a metal detector 9 and the signal is transmitted to an arithmetic processing means 14. The processing means 14 reads the output of a speedometer 8 and decides the timing for ascending command of a length measuring gage 11. The measuring gage 11 abuts the lower face of the material to be rolled and transmits to the processing means 14 the length measuring pulse according to the moving distance of the rolling material. A width gate 7 transmits the metal in signal to the means 14 and measuring value to the means 14 by starting the width measurement as well. A height detector 12 measures the up camber thickness to transmit to the means 14. The means 14 reads the up camber quantity or plate thickness from the measured width transmitted from the width gage 17 and transmitted from the height detector 12, calculates the normal plate width and adjusts the roll interval of the vertical rolling mill 3 by setting to the timing.</p> |
