Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of roll detection, in particular relates to a roll surface online detection and repair integrated equipment. BACKGROUND

[0002] The roll is a key tool in the process of making plate, thin strip and film material, and the surface precision of the roll directly affects the thickness and surface quality of the processed product. During the manufacturing and post-wear repair of the roll, grinding and real-time detection are required to achieve high-precision surface quality. Current roll surface grinding detection methods include ultrasonic, optical fiber and eddy current. Detection methods include offline and online detection. Offline detection, which detects the surface quality of the roll after processing, is often used for quality inspection and does not have the functions of real-time monitoring and adjusting processing parameters to adjust processing quality. Online detection has the function of real-time adjustment by real-time understanding of the processing status.

[0003] The existing online detection technology still has significant bottlenecks in actual application. On the one hand, oxidation scale, metal dust and other pollutants generated during the rolling process are easy to adhere to the detection area, causing sensor misjudgment or missed detection. On the other hand, the existing cleaning device uses high-pressure gas blowing, which can remove some loose impurities, but easily causes secondary flying of dust to pollute the surface of the rolled material, and has limited effect on the removal of strongly adhering deposits.

[0004] Therefore, we provide a roll surface online detection and repair integrated equipment to solve the above problems. SUMMARY
