镁合金薄板的重绕设备
摘要：
本发明具备能够将缠绕于固定心轴的镁合金的卷材(C)开卷的开卷机(1)、将从卷材(C)开卷的镁合金薄板(S)加热至规定温度的加热炉(4)、对镁合金薄板(S)的形状不良进行修正的矫平机(6)、切下薄板的两侧缘的修边机(2)以及对镁合金薄板(S)进行重新卷绕的卷绕机(3)。依照本发明，能够对将镁合金薄板缠绕于固定心轴的卷材进行重新卷绕，除掉固定心轴，并且，能够对由于多道次轧制而产生的板宽端部的裂缝部和形状不良部进行矫平和修边，制造高品质的产品线圈。
摘要（英）：

A recoiling facility of magnesium alloy sheet comprises a rewinding machine (1) for making a coil material (C) of magnesium alloy wound around a fixed mandrel rewindable, a furnace (4) for heating a magnesium alloy sheet (S) rewound from the coil material (C) to a predetermined temperature, a leveler (6) for correcting the poor profile of the magnesium alloy sheet (S), a trimmer (2) for trimming the opposite side edges of the sheet, and a winding machine (3) for rewinding the magnesium alloy sheet (S). The coil material where the magnesium alloy sheet is wound around the fixed mandrel is rewound and the fixed mandrel is removed, and then crack portion and poor profile portion occurring at the plate width end portion by multipass rolling are leveled and trimmed thus producing a high quality production coil.
