The conventional techniques cannot minimize increase in yield loss and slab thickness caused by unsteady deformation in top and rear end portions during reduction of the width of a slab, and cannot shape a slab with desired target dimensions at high productivity. With respect to a width pressing machine 2 that reduces the width of a slab, a horizontal rolling mill 1 is arranged at the upstream side of the slab conveying direction, or an entry-side horizontal rolling mill 1 and an exit-side horizontal rolling mill 3 are respectively arranged at the upstream side and downstream side. A slab shape control equipment thus configured is used to simultaneously perform rolling by the horizontal rolling mill 1 or by horizontal rolling mill 1 and horizontal rolling mill 3, and reduce the width of a slab by the width pressing machine 2 on one hot slab 10. |
