Abstract
Provided is a cooling system for a hot-rolled steel strip capable of increasing the cooling rate for rapidly cooling a rolled steel immediately after rolling and suitable for an apparatus for manufacturing a hot-rolled steel strip having a fine-grained structure. For this purpose, guides (A,B) having guiding surfaces () to guide a rolled steel (W) exiting work rolls (A,B) in the conveyance direction are provided at exits of the work rolls in a final stand (Sn) of a finish rolling mill line in a manner that the guides can follow a change in the diameter of the work rolls, a number of injection holes (A,B) are formed in the guides, and a number of rolled steel cooling nozzles (A,B) are provided to spray a large amount of cooling water through the injection holes directly onto the rolled steel.
