  • Patent number: 8506879
    Abstract: A method for cooling a hot strip conveyed on a run-out table after finishing, including ejecting rod-like flows of cooling water from nozzles to the upper surface of the steel strip such that the flows are inclined toward a traveling direction of the steel strip, and draining the cooling water using draining means disposed downstream of the nozzles.
    Type: Grant

  • Patent number: 8444909
    Abstract: A hot-strip cooling device for cooling a hot strip that has been subjected to finish rolling while being conveyed over a run-out table. The device includes a plurality of cooling nozzles that are disposed above a steel strip and eject rod-like flows of coolant at an ejection angle tilted toward the upstream side in a steel-strip traveling direction; and purging means that is disposed on the upstream side with respect to the cooling nozzles and purges the coolant that has been ejected from the cooling nozzles and resides on the steel strip.

  • Patent number: 8318080
    Abstract: A device and a method for cooling a hot strip capable of uniformly cooling the hot-rolled steel strip from the leading end to the trailing end thereof during cooling of the steel strip using cooling water are provided. A cooling device 10 includes a plurality of tubular nozzles 15 inclined so as to eject rod-like flows of cooling water to a steel strip 12 at an ejecting angle ? in a traveling direction of the steel strip 12 and a pinch roller 11 disposed downstream of the tubular nozzles, the steel strip 12 to be nipped between the pinch roller 11 and a table roller 8.

  • Patent number: 8231826
    Abstract: A hot-strip cooling device and a cooling method are provided wherein uniform cooling of a hot-rolled steel strip using coolant is possible from the leading end to the trailing end of the steel strip. A cooling device (10) includes a plurality of round nozzles (15) disposed obliquely in such a manner as to eject rod-like flows of coolant at an ejection angle ? toward the upstream side in a direction in which a steel strip (12) travels, and a pinch roll (11) disposed on the upstream side with respect to the round nozzles (15) and configured to pinch the steel strip (12) in combination with a roller table (8).

  • Publication number: 20090126439
    Abstract: There are provided a cooling device and a cooling method for a hot-rolled strip in which the strip can be uniformly cooled from a leading edge to a trailing edge with coolant by properly realizing a great cooling ability and a stable cooling zone. Specifically, the following three methods are adopted. (1) Round nozzles 14 for ejecting inclined rodlike flows of coolant to a downstream side in the traveling direction of a strip 12 and round nozzles 14 for ejecting inclined rodlike flows of coolant to an upstream side in the traveling direction are arranged on an upper side of the strip 12 so as to oppose each other. (2) Round nozzles 14 for ejecting inclined rodlike flows of coolant from the upstream side of a roller table 9 toward just above the roller table 9 and round nozzles 14 for ejecting inclined rodlike flows of coolant from the downstream side of the roller table 9 toward just above the roller table 9 are arranged on the upper side of the strip 12 so as to each other.
