<p>PURPOSE:To automate the delay table operation by forecasting the time when the rear of the preceding sheet bar and the front of the following sheet bar go in and out from the first stand of the finish rolling mill in case the sheet bar is conveyed with the delay table from the rough rolling mill to the finish rolling mill. CONSTITUTION:The sheet bar is conveyed with the delay table 16 from the rough rolling mill 14 to the finish rolling mill 22, and it is rolled. When the position detector 38 mounted at the delivery of the final stand R5 of the rough rolling mill 14, and the rear end of the following sheet bar have passed through the final stand R5 of the rough rolling mill 14, the first stand F1 of the finish rolling mill which is at the rear end of the preceding sheet bar forecasts the time and the fitting time of the stand F1 which is at the front end of the following sheet bar, from the conveying information which includes the rear end position of the preceding sheet bar detected with the position detector 46. As a result of calculating the space of both the sheet bars with a computer 40, comparing it with the sheet bar space setting value 42, and adjusting the conveying speed of the following sheet bar automatically, the sheet bar space can be always proper value, and the conveying density of sheet bars can be elevated.</p> |
