DEVICE AND METHOD FOR CROSS-CUTTING A HOT-ROLLED STRIP

The invention relates to a method and device for cross-cutting a hot-rolled strip (1), comprising ascertaining (2) the thickness of the hot-rolled strip (1); selecting first drum shears (4) for a thick hot-rolled strip or second drum shears (5) for a thin hot-rolled strip based on the thickness of the hot-rolled strip (1), wherein the first drum shears (4) are selected for a thick hot-rolled stripwith a strip thickness of 4 mm to 28 mm and a strip displacement speed of less than 2.25 m/s and the second drum shears (5) are selected for a thin hot-rolled strip with a strip thickness of 0.6 mm to 6 mm and a strip displacement speed of more than 1.5 m/s; cooling the hot-rolled strip in a cooling section (3); cross-cutting the cooled hot-rolled strip (1) with the first or second drum shears (4, 5), wherein a first driver roller unit (6) and a second driver roller unit (7) are placed on the hot-rolled strip to stabilise the hot-rolled strip (1) during cross-cutting; and ejecting the cross-cut hot-rolled strip throu
