SHAPE-CORRECTING AND ROLLING METHOD AND SHAPE-CORRECTING DEVICE FOR HIGH-STRENGTH STEEL

摘要

There are provided a shape-correcting and rolling method and a shape-correcting device for effectively correcting the shape of high-strength steel. The shape-correcting and rolling method includes: transferring a hot-rolled coil to a pay-off reel after cooling the hot-rolled coil or directly through a hot rolling to skin pass mill direct transfer process; unwinding the coil from the pay-off reel; correcting a shape of a strip unwound from the coil by using a heat pipe roller; and rewinding the strip as a coil.
