    摘要： A sheet crown control method and apparatus for use in endless rolling in which consecutively fed sheets are joined to each other to be continuously rolled through a rolling equipment line. The rolling equipment line includes a junction device for joining consecutively fed sheets to each other, a plurality of stands arranged in tandem on the downstream side of the junction device and having a roll bender load adjusting mechanism and a roll crossing mechanism. The roll cross angle of rolls incorporated in a stand of each rolling mill is set at a predetermined value beforehand if there is a roll cross angle that will enable a target sheet crown to be applied to each sheet and the roll bender load of each stand is adjusted on-line, thereby effecting sheet crown control. Rolling also may be performed while adjusting the roll cross angle of rolls incorporated in stands of each rolling mill on-line together with the roll bender load. The roll bender load and the roll cross load may be adjusted in a transition region where a junction between sheets exists or in a stationary region where sheets of the same material follow one after another.

    摘要翻译： 一种用于环形轧制的片材冠控制方法和装置，其中连续供给的片材彼此接合以通过轧制设备线连续轧制。 轧制设备线包括用于将连续供给的板彼此接合的接合装置，在接合装置的下游侧串联布置的多个机座，并具有辊弯机负载调整机构和轧辊交叉机构。 如果存在能够将目标片材冠部施加到每个片材上的辊交叉角度，并且每个机架的轧辊弯曲装载负载为每个轧机的辊弯曲载荷，则预先将每个轧机的支架中包含的辊的辊横角设定为预定值 在线调整，从而进行表冠控制。 也可以在轧制机上轧辊交叉角度的同时进行轧制，同时辊轧机负载与轧制机在线连接。 可以在存在片材之间的接合处的过渡区域中或在相同材料的片材一个接一个地停留的固定区域中调节轧辊弯曲机负载和轧辊交叉负载。
