Title:
COOLING FACILITY AND COOLING METHOD OF STEEL PLATE
Document Type and Number:
WIPO Patent Application WO/2007/026906
Kind Code:
A1
Abstract:
Cooling facility and method of a steel plate for cooling the steel plate properly
on a hot rolling line by a compact structure when controlled rolling of the steel
plate is performed. The cooling facility of a steel plate, which is a cooling facility
for supplying cooling water to the upper and lower surfaces of the steel plate
(10) while passing the steel plate (10) when it is hot rolled, has nozzles (22a,
22b) for supplying cooling water obliquely toward the upper surface of the steel
plate (10) from above, wherein the nozzles (22a, 22b) are arranged such that ejections
of cooling water on the steel plate (10) oppose each other in the carrying direction
of the steel plate (10). More concretely, it is a passing type cooling facility
(20) having a large water volume density of 4 m3/m2min or
above.
