RECOILING FACILITY OF MAGNESIUM ALLOY SHEET

摘要

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.
