Abstract: A finishing rolling device for manufacturing a thin magnesium strip based on a coil fed to the device includes a roll stand for accommodating at least two working rolls (32, 33) that define a roll gap. A first coiler accommodates the coil and feeds the magnesium strip to the roll gap and a second coiler for winding up the magnesium strip after it passes through the roll gap. The first coiler is provided with a heating device and a hood arrangement that shields the coil or the magnesium strip against heat radiation. The hood arrangement of the first coiler features a coil passage opening for introducing the coil into the hood arrangement on its housing side that faces away from the roll stand.
