DESCALING DEVICE IN HOT ROLLING LINE, DESCALING METHOD FOR MATERIAL TO BE ROLLED IN HOT ROLLING, AND METHOD FOR MANUFACTURING HOT-ROLLED METAL STRIP

摘要

PROBLEM TO BE SOLVED: To provide a descaling device in a hot-rolling line capable of preventing problems of break or the like of a support mechanism or a hose from occurring due to deformation of a flexible hose when the descaling device is lifted or lowered corresponding to variation of thickness or warp of a material to be rolled, and also to provide a descaling method for the material to be rolled in hot rolling, and further to provide a method for manufacturing a hot-rolled metal strip.;SOLUTION: Pipes 4 for supplying water toward upper descaling headers 3 are made bendable through swivel joints 4a.;COPYRIGHT: (C)2011,JPO&INPIT
