<p>PURPOSE:To adequately control the plate thickness by determining the edge of a thin plate thickness part after it is rolled in accordance with the value of thickness of the whole width of a stock to be rolled which is detected on the inlet side of a rolling mill, setting the plate thickness of the center part after it is rolled and rolling the stock with the set value. CONSTITUTION:The edge of the thin plate thickness part is determined on the inlet side of the rolling mill, set values of plate thicknesses of the center part and the edge part after they are rolled are required and rolling is carried out by the set value of the plate thickness of the center part. In that case, after the tip of the stock to be rolled arrive at the outlet side of the rolling mill, the thickness of the thin edge of the outlet side is detected and the control object of the plate thickness is changed over so that the plate thickness makes a set value of the plate thickness of the preset edge plate. Thus, a desired plate thickness value can be obtained.</p> |
