Title:
METHOD FOR CONTINUOUSLY EDGING HOT SLAB
Document Type and Number:
Japanese Patent JPH07275901
Kind Code:
A
Abstract:
PURPOSE: To suppress extreme swelling phenomenon in the center of the cross section of slab that is generated when a narrow slab is strongly edged at the time of edging a hot slab.
CONSTITUTION: Devices 4 for clamping the slab 2 and imparting tensile stress in the advancing direction to the slab are provided before and behind a press device l for edging the hot slab 2. Then, the range of the tensile stress σT(kgf/ mm2) is set to 5.0≤σT≤10.0(kgf/mm2). When this edging method is used, the extreme swelling phenomenon in the center that is generated when the narrow slab 2 is strongly edged is suppressed without affecting the quality of the slab 2.
