Title:
HOT ROLLING EQUIPMENT AND METHOD FOR MANUFACTURING STEEL PRODUCT USING THE HOT ROLLING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2008/111233
Kind Code:
A1
Abstract:
This invention provides a holding apparatus for lifting a rolling material on
a transfer table to a height enough to allow a succeeding rolling material to pass
through on the table, for example, for conducting passing rolling, in a hot rolling
equipment, which apparatus can be installed without the need to ensure a wide
space and can properly lift a rolling material. A steel product (10) is lifted
while holding between both sides of the transfer table by a holding part (33a)
in a plurality of sets of holding arms (33) mounted on frames (31, 32) which are
lowered or lifted along four braces (21) provided on both sides of the transfer
table (10). In the holding apparatus provided with the holding arm, the holding
part in the holding arm has a proper heat insulating structure. There are also
provided a hot rolling equipment, which, even when a controlled rolling material
for which waiting time for cooling is necessary is included, the idle time in a
hot rolling machine can be reduced to improve the rolling efficiency, and a hot
rolling method using the hot rolling equipment.
