SHAPE CONTROL METHOD OF ADVANCED HIGH STRENGTH STEEL AND SHAPE CONTROL DEVICE THEREOF

摘要

The present invention provides a shape correction and rolling method for high strength steel to effectively achieve the shape correction of the high strength steel, which includes a hot-rolling skin-pass-mill direct-coupling forwarding step in which a hot-rolled coil is sent to a pay-off reel or an unwinding step in which the coil is unwound form the pay-off reel after having been passed through a cooling step; a shape-correcting step in which a heat-pipe roll is used to correct the shape of the unwound strip; and a re-winding step in which the strip is re-wound into a coil.
