摘要： A method for producing a metal sheet with raised lines uses a rolling mill including a plurality of roll stands and produces a metal sheet including, on an upper surface, a plurality of raised lines extending in a rolling direction. The method includes a preparing step, a choosing step, an incorporating step, and a forming step. In the preparing step, a grooved roll is prepared, the grooved roll including a plurality of grooves in an outer peripheral surface. In the choosing step, a stand at least one stage before the last stand is chosen. In the incorporating step, the grooved roll is incorporated in the rolling mill as an upper roll of the chosen, specified stand. In the forming step, a workpiece is rolled by the rolling mill and is formed into a metal sheet with raised lines formed corresponding to the respective grooves of the grooved roll. At this point, in the forming step, until a leading edge of the workpiece reaches a stand next to the specified stand, a maximum rolling reduction achieved by rolls of the specified stand is set to a provisional value that is lower than a required value. After the leading edge of the workpiece reaches the stand next to the specified stand, the maximum rolling reduction achieved by the rolls of the specified stand is changed to the required value.
摘要翻译：用于生产具有凸起线的金属板的方法使用包括多个轧机机架的轧机并且产生金属板，该金属板在上表面上包括沿轧制方向延伸的多条凸起线。该方法包括准备步骤，选择步骤，并入步骤和形成步骤。在准备步骤中，制备开槽辊，开槽辊在外周表面中包括多个凹槽。在选择步骤中，选择最后一个展位前至少一个展位的展位。在合并步骤中，槽轧辊作为选定的特定机架的上辊并入轧机中。在成形步骤中，工件通过轧机轧制并且形成为具有与沟槽辊的相应沟槽对应形成的凸起线的金属板。此时，在成型步骤中，直到工件的前缘到达与指定台架相邻的台架，由指定台架的辊子实现的最大压下量被设定为低于所需值的临时值。在工件前缘到达指定支架旁边的支架后，指定支架轧辊达到的最大压下量将变为所需值。

摘要： A method for producing a metal sheet with raised lines uses a rolling mill including a roll stand and produces a metal sheet including, on each of an upper surface and a lower surface, a plurality of raised lines extending in a rolling direction. The method includes a preparing step, an incorporating step, and a forming step. In the preparing step, grooved rolls are prepared, each of the grooved rolls including a plurality of grooves in an outer peripheral surface. In the incorporating step, the grooved rolls are incorporated in the roll stand as an upper roll and a lower roll, respectively. In the forming step, a workpiece is rolled by the rolling mill and is formed into a metal sheet with raised lines formed corresponding to the respective grooves of the grooved rolls.
