Research and application of camber control technology in hot rolling rough rolling area
The camber defect in the hot rolling rough rolling area affects the shape quality and rolling stability of the strip steel.The research on online detection and control technology of camber has al-ways been a hot topic of industry.This study develops an online detection and control technology for camber based on image recognition.By installing high-definition cameras in front and behind the stand to obtain strip steel images,image processing technology is used to measure and recognize the contour shape of the strip steel.Combined with actual measurement data,equipment data,model set-ting data,etc.during the rolling process,a camber adjustment model is constructed,online automatic feedforward control function for camber is implemented.This technology has been put into online ap-plication on a hot rolling production line in China,with an accuracy rate of over 95％for adjusting the camber direction.It can effectively reduce production costs and labor intensity,improve the auto-mation level of the production line,and has high application value and development prospects.
