Title:
熱延鋼帯の製造方法及び製造装置
Document Type and Number:
Japanese Patent JP7342898
Kind Code:
B2
Abstract:
To provide a hot-rolled steel strip manufacturing method that made it possible both to achieve a target coiling temperature for a steel material whose length after finish rolling is shorter than the length of a runout table and to appropriately wind the steel material with a winder, and also to provide a manufacturing apparatus for a hot-rolled steel strip.SOLUTION: A hot-rolled steel strip manufacturing apparatus 1 includes a cooling control unit 14 that performs a control process of: after the leading edge part Sa of steel S begins to enter the runout table 5 at the finishing rolling speed, reducing the transport speed of the steel S to a decelerating speed of less than 80 mpm; conveying the steel material S at the deceleration speed; and, before the leading edge part Sa of the steel S is started to be wound on the winder 8, accelerating the conveying speed of the steel S to a winding speed between 150 mpm and 400 mpm.SELECTED DRAWING: Figure 1
