<p>PURPOSE:To obtain the target plate crown and the target flatness extending over the whole rolling cycles by providing the allowable range in the flatness of the outside of each stand as well as making the product plate crown and the product flatness a target value and by taking into consideration the freedom thereof. CONSTITUTION:The product target flatness, the target plate crown, the folling conditions of the target plate thickness and the target power distribution ratio of each stand are set up in the step 101. Steps 102, 106, 110 are No.2, No.3 steps calculating the plate thickness and flatness of the outside of each stand. The steps 104, 107 perform the check of the flatness and steps 108, 109 set up the target flatness of each stand and also feedback to the steps 106 or 110. The step 111 makes the plate thickness of the plate thickness of the outside of each stand which is calculated by the steps 102, 106, etc. a drafting schedule. With these methods the final target plate crown and target flatness are obtd.</p> |
