摘要： During rolling with a rolling mill, which includes a sheet shape altering device capable of altering a mechanical sheet crown, while the sheet shape altering device is operated correspondingly with a target mechanical sheet crown set value during the dimensional alteration in rolling, the invention enables a stable sheet shape to be achieved, even when the mechanical sheet crown is altered to a large extent during rolling. Specifically, the target mechanical sheet crown set value, during the dimensional alteration in rolling, is previously set based on target mechanical sheet crown set values, before and after the dimensional alteration, prior to start of the dimensional alteration in rolling. The sheet shape altering device is then operated so that an actual mechanical sheet crown, during the dimensional alteration in rolling, is equal to the target mechanical sheet crown set value during the dimensional alteration in rolling.
摘要翻译：在使用轧机进行轧制时，其包括能够改变机械板材冠的片材形状改变装置，同时在轧制尺寸变化期间相应地利用目标机械板材凸度设定值来操作片材形状改变装置，本发明使得即使在轧制过程中机械板材冠部被很大程度地改变，也能够实现稳定的板材形状。具体而言，在轧制尺寸变更开始之前，在尺寸变更前后，基于目标机械板冠设定值预先设定轧制尺寸变更中的目标机械板凸度设定值。然后操作片材形状改变装置，使得在轧制尺寸变化期间实际的机械板材冠在轧制尺寸变化期间等于目标机械板材凸度设定值。

摘要： Assuming that the processes of joining, rolling, coiling, etc. of a material is evaluated by a preset speed pattern after the extraction from a heating furnace, the required time is predicted and calculated for both of a preceding material and a following material. At the time when the following material can catch up with the preceding material at an aiming position on the line, the following material is extracted from the heating furnace according to the result of the above prediction calculation. Control is carried out so that both of the preceding material and the following material finish the process at a preset speed. Also, the traveling speed of the following material is controlled according to the position and the speed of the tail edge of the preceding material in a section close to the catch-up position so that a distance between the tail edge of the preceding material and the leading edge of the following material be closed. Thereby, three of the tail edge of the preceding material, the leading edge of the following material, and a movable joining apparatus are controlled at the aiming position on the hot rolling line so as to be in a positional relationship suitable for joining, by which the joining operation is completed properly in the travel zone of the joining apparatus.
摘要翻译：假设在从加热炉中取出之后，通过预先设定的速度模式对材料的接合，轧制，卷取等进行评价，对于前述材料和后续材料，预测和计算所需时间。在以下材料可以在线上的瞄准位置赶上前述材料时，根据上述预测计算的结果从加热炉中提取以下材料。进行控制，使得前述材料和以下材料都以预定速度完成该过程。此外，根据在接近追赶位置的部分中的先前材料的尾部的位置和速度来控制以下材料的移动速度，使得在先前材料的尾部边缘与以下材料的前缘关闭。由此，将前一种材料的尾部边缘，以下材料的前缘中的三条和可动接合装置控制在热轧生产线上的瞄准位置，以便处于适于接合的位置关系，由此接合操作在接合设备的行进区域中正确地完成。
