Description

Technical Field

[0001] The invention belongs to the technical field of surface treatment of hot-rolled stainless steel composite plates, and in particular relates to a device and method for eliminating surface defects of hot-rolled stainless steel composite plates. Background Art

[0002] There are many reasons for the surface defects of hot-rolled stainless steel composite plates. Iron oxide scale intrusion is one of the most common surface defects in the hot rolling process. It is usually in the form of small spots, fish scales, strips, and blocks, and is irregularly distributed on the surface of the strip. Due to the different sizes of the oxide scales and the different forces of pressing into the plate, some are loose and easy to fall off, while others are pressed into the plate surface and not easy to fall off. Secondly, during the heating process, the slab is severely oxidized, the surface of the rolling mill work roll is rough or sticky with foreign matter, which will cause continuous pits of different sizes and depths on the surface of the steel plate. The existence of the above two problems seriously affects the quality of hot-rolled stainless steel composite plates. The hot-rolled steel plate is kept at a high temperature after annealing. First of all, The steel plate needs to be cooled. For surface defects caused by loose and easily falling oxide scale on the surface, the plate surface can be cleaned, scraped and purged. For oxide scale that is pressed into the plate surface and is not easy to fall off, as well as the pitting produced during the hot rolling process, the plate surface needs to be cleaned, scraped and purged. The defect position is determined by the CCD camera, the plate is centered by the centering mechanism, and the plate surface is cleaned again to prevent residual impurities and water stains after cleaning and cooling from affecting the grinding process. Then, the corresponding grinding roller is selected according to factors such as the size, shape, and degree of concave-convexity of the oxide scale and pitting, and the plate is ground at a fixed point.

[0025] 2) Motor II drives connecting slider I to move via bidirectional lead screw I. Connecting slider I drives the buffer plate downward to move.

[0026] 3) Motor IX drives the bidirectional screw II to rotate, causing the connecting slider V installed on the bidirectional screw II to move. The centering distances of the two sets of connecting sliders V are equal. The vertical guide rollers installed at the bottom of the connecting sliders V allow the plates to be centered and calibrated.

Motor V drives the two sets of conveying rollers to rotate through the transmission belt I, and the plates are conveyed, stopped, and returned as needed; Motor VI drives the front and rear positioning rollers to rotate through the transmission belt II to assist in positioning the plates and conveying them forward; Motor III, which is set on the side of the conveying and positioning mechanism, drives the movable positioning frame to move in the direction of the screw I by driving the screw I to rotate. Motor IV, which is set on the movable positioning frame, drives the connecting slider II to move in the direction of the screw II by driving the screw II to rotate. The lower part of the connecting slider II is connected to the electric push rod positioning plate, which can adjust the position of the fine cleaning mechanism and the fixed-point grinding mechanism in real time according to the detected defect location;

[0028] 5) Electric push rod II drives the fine cleaning mechanism to rise and fall to the appropriate height. Motor XIII controls bevel gear I, which meshes with bevel gear II. Bevel gear II drives two sets of circular brushes to rotate and clean the surface of the plate through transmission belt III. Motor XIII also drives the circular plate to rotate. The rotation of the circular plate drives the swing bracket to swing, causing the strip brush plate at the bottom of the swing bracket to swing and clean the surface of the plate. The circular brush rotates and cleans, and the strip brush swings to complete the fine cleaning of the plate surface, preventing impurities from affecting the subsequent grinding and repair process;

[0029] 6) Electric push rod I controls the lifting plate I to move up and down to the appropriate position, and motor X controls the rotation of the rotating bent plate through the rotating shaft. The appropriate grinding roller can be selected between the coarse grinding roller and the fine grinding roller. The grinding roller positioning frame is connected to the rotating bent plate through spring III directly above, and the grinding roller positioning frame is connected to the limit plate through spring II diagonally above. The springs in two directions can provide flexible buffering for the grinding roller, reduce the impact of the grinding and repair work on the defect-free position, reduce the burden on the equipment, and efficiently complete the grinding and repair process.
