NOZZLE HEADER COOLING DEVICE DEVICE FOR PRODUCING HOT ROLLED STEEL SHEET AND METHOD FOR PRODUCING HOT ROLLED STEEL SHEET

摘要

Provided is a nozzle header that sprays pressurized water onto a high temperature object and that can prevent components provided to spray nozzles from being deformed and damaged by heat at the time of operation due to radiant heat from said high temperature object. This nozzle header for spraying water onto an object comprises: a header that supplies pressurized water; one or more spray nozzles that are supplied with the pressurized water from the header and that spray the pressurized water; and a heat removal structure attached so as to contact at least one of the spray nozzles. The heat removal structure includes the heat removal structure itself and a cooling medium flow path through which a cooling medium for cooling the spray nozzles passes.
