Abstract

According to conventional technology a slab cannot be formed into desired target dimensions with high productivity while minimizing yield loss and an increase in thickness due to unsteady deformation of front and rear ends during slab width reduction. Slab shape control equipment includes a horizontal rolling machine (1) disposed on the upstream side or an entry side horizontal rolling machine (1) and an exit side horizontal rolling machine (3) disposed on the upstream side and the downstream side respectively of a width press machine (2) for slab width reduction with respect to the direction of slab transportation. By using the equipment a single hot slab (10) is subjected to thickness rolling by the horizontal rolling machine (1) or the horizontal rolling machine (1) and the horizontal rolling machine (3) and to width reduction by the width press machine (2) simultaneously.
