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.

Method for cooling hot strip

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.

Hot-strip cooling device

A cooling device and 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.

Cooling device and cooling method for hot strip

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 deviceincludes a plurality of tubular nozzlesinclined so as to eject rod-like flows of cooling water to a steel stripat an ejecting angle &#x3b8; in a traveling direction of the steel stripand a pinch rollerdisposed downstream of the tubular nozzles, the steel stripto be nipped between the pinch rollerand a table roller

Device and method for cooling hot strip

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 () includes a plurality of round nozzles () disposed obliquely in such a manner as to eject rod-like flows of coolant at an ejection angle &#x3b8; toward the upstream side in a direction in which a steel strip () travels, and a pinch roll () disposed on the upstream side with respect to the round nozzles () and configured to pinch the steel strip () in combination with a roller table ().
