<p>PURPOSE:To increase the shape quality and products yield by selecting the optimal gains for the plate thickness, plate width and estimated crown on each rolling pass and by performing the correction of the roll draft position based on this optimal gain. CONSTITUTION:The list of optimal gains is made and prepared on each pass by experienced or off-line simulation model in advance classified by the plate thickness, plate width and estimated crown in a PID gain setting part 7. The plate thickness, plate width and estimated crown information on each rolling pass are given from the host computer each rolling stock, the optimal gains list is retrieved on each time and the decided optimal gains are automatically selected. The divergence command of the right and left rolls is operated by the prescribed equation from the right and left differential load detected by a load cell 3 and the meandering of the rolling stock 2 is controlled by controlling the servo valve 6 for hydraulic automatic control. With this method, the shape quality and yield of the rolling stock 2 are increased.</p> |
