Abstract
PURPOSE:To detect the steady and contingent slip quantities of a strip by determining the deviation between the 1st forecasting line for coil diameters in a wound coil and the 2nd forecasting line for coil diameters regressively analyzed by the number of revolutions of a master roll. CONSTITUTION:The 1st forecasting line A for coil diameters is determined from the number of revolutions of a wound coil 2 and the thickness of a strip 1 to be coiled. The coil diameters given by the number of revolutions of the coil 2 and the number of revolutions of a master roll 4 are linearly regressively analyzed with lapse of time, whereby the 2nd forecasting line B for coil diameters is determined. Here, if no slips are produced in the roll 4, both forecasting lines A, B coincide. If there is a slip, a deviation is produced in the lines A, B and if said deviation is detected, the steady slip quantity is detected. If a contingent slip is produced, plot points deviating from the line B are obtained and if the variances between these points and the line B are detected, the contingent slip quantity is detected.
