熱間圧延鋼帯の蛇行量測定装置及び熱間圧延鋼帯の蛇行量測定方法
Document Type and Number:
Japanese Patent JP7222415
Kind Code:
B2
Abstract:
To provide an apparatus for measuring a meandering amount of a hot rolled steel strip and a method for measuring a meandering amount of a hot rolled steel strip in which an edge position of the hot rolled steel strip is adequately and rapidly detected even when vapor is completely covering the edge of the hot rolled steel strip.SOLUTION: An apparatus 2 for measuring a meandering amount of a hot rolled steel strip comprises: an edge position detection device 3 which includes an infrared camera 4 imaging intensity distribution of an infrared ray emitted from the surface of the travelling hot rolled steel strip 10 of 600-1000°C and an edge position detection part 5 detecting edge positions at both ends in the width direction of the hot rolled steel strip 10 based on the intensity distribution of an infrared ray imaged by the infrared camera 4; and a meandering amount calculation device 6 calculating a meandering amount of the hot rolled steel strip 10 based on the edge positions at both ends in the width direction of the hot rolled steel strip 10 detected by the edge position detection device 3. A measurement period of the meandering amount of the hot rolled steel strip 10 for the calculation of the meandering amount by the meandering amount calculation device 6 is 1 msec.SELECTED DRAWING: Figure 1
