摘要： PURPOSE:To improve the accuracy of a speed reducing instruction by calculating the thickness of a strip wound around a payoff reel and the diam. of a coil on the reel and calculating the length of a strip remaining in coil basing on the calculated sheet thickness and the coil diam. CONSTITUTION:The number of revolutions NWR of a work roll 5 located just before a sheet thickness detector 4 is measured at every revolution of a payoff reel 1, to calculate the coil diam. D'POR of a coil 3 before (n) revolutions and the coil diam. DPOR at present in order to calculate the average thickness hE of the strip between them by using prescribed equations. After that, the coil diam. DPOR is calculated at every revolution of the reel 1 basing on the sheet thickness hE by the prescribed equations, to calculate the length of a strip remaining in coil basing on the thickness hE and the diam. DPOR; and when the length of strip, calculated basing on the present speed of the strip and the deceleration of a rolling mill, becomes equal to the length of the strip remaining in coil or shorter than it, a speed reducing instruction is outputted to the mill. In this way, the instruction of deceleration to the mill is exactly performed.

摘要： PURPOSE:To improve the accuracies of the length and thickness of an off-gauge part, by changing the sheet thickness at the top and bottom parts of a coil during rolling, and performing the rolling by combining a schedule calculation for obtaining the target sheet thickness and an AGC in absolute value of a whole stand. CONSTITUTION:The length of an outer peripheral portion of one turn is calculated by turns of rolled coils by inputting a coil information about the thickness, the width, the weight, and the coil thickness, etc. of a sheet to be rolled, and the result is used as the target off-gauge length. The off-gauge length is used in calculation as the length at the inlet side of one stand, and is used for a changing point of the sheet thickness during rolling. For changing the sheet thickness in actual rolling, a rolling draft, the number of revolutions, an AGC in absolute value are set up and a change of setting of a thickness gauge is performed by tracking the changing point of the sheet thickness during rolling. In a case when a sheet is free from tension at the front or rear side of each stand by the condition of biting or passing through of the sheet resulting from passing or run-out of the sheet at said stand, a schedule calculation is performed so as to obtain the target sheet thickness. Two kinis of the target sheet thickness at the middle and the off-gauge parts may be required.
摘要翻译：目的：通过改变轧制过程中线圈顶部和底部的板厚度，通过组合用于获得目标板厚度的进度计算来进行轧制，提高不规则部件的长度和厚度的准确性和一个整体平台的绝对值的AGC。构成：通过输入关于被轧制片材的厚度，宽度，重量和线圈厚度等的线圈信息，通过卷取的线圈的匝数来计算一圈的外周部的长度，结果用作目标超标长度。计算中使用的不合格长度作为一个支架入口侧的长度，用于轧制时板材厚度的变化点。为了实际轧制中的板厚变化，设定轧制牵伸，转速，绝对值的AGC，并且通过跟踪轧制时的板厚变化点来进行厚度计的设定变化。在通过在所述台架上由片材的通过或流出而导致的片材的咬合或通过的情况下片材在每个支架的正面或背面处没有张力的情况下，进行计划计算以获得目标片材厚度。可能需要在中间的目标片材厚度和不合格的部件的两个激光。
