Abstract
PURPOSE: To detect the shape on the hot rolling line, to automate operations and to improve the quality, by obtaining a displacement fluctuation width in each point of the strip in the breadthwise direction at a prescribed time and by subtracting a minimum fluctuation width from this width.
CONSTITUTION: Passage positions of a strip 1 are measured in ≥1 periods of plate waves plural times at plural measuring points, which are arranged in the breadthwise direction of the strip 1, by measuring devices 2-1W2-7 for the passage position and are stored in 5. Abnormal values are eliminated from measured signals, and a fluctuation width as the difference between a maximum value and a minimum value is obtained at every measuring point from the rest measured values, and a minimum fluctuation width out of fluctuation widths is obtained at respective measuring points, and the difference between the fluctuation width at each measuring point and the minimum fluctuation width is determined as the crest value of plate waves at each measuring point, thereby detecting the shape of the strip 1.
