SLAB CAMBER SUPPRESSION METHOD, CAMBER SUPPRESSION DEVICE, AND SLAB GUIDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for simultaneously suppressing camber deformation and slab thickness deviation within a slab width during a width pressure reduction process, forming a product sectional surface into a rectangular shape, and suppressing the camber deformation, and a guiding device.;SOLUTION: The slab camber suppression method is characterized in that when slab width pressure reduction is carried out by a width pressure reduction device during a hot rolling process, according to an asymmetric factor and a width pressure reduction condition factor for width rolling, a slab entry angle is continuously controlled with the progress of pressing by a width-direction position control device installed on the entrance side of the width pressure reduction device, the width-direction deviation of a dock bone generated during the width pressure reduction is reduced, and camber deformation generated on the exit side of the width pressure reduction device is reduced.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2016,JPO&INPIT
