Problems solved by technology

At present, it has been determined that there are two typical rolling mill chatter that affect the surface quality of the plate and strip: one is the third octave chatter, which causes obvious changes in the thickness of the rolled piece and fluctuations in the tension between stands; It is the fifth octave flutter, which causes the vibration pattern on the surface of the rolled piece perpendicular to the rolling direction
The fluctuation of the rolling entrance speed of the high-speed rolling mill causes the fluctuation of the rolling force, which causes the flutter of the high-speed rolling mill and seriously affects the quality of rolled steel products

Abstract

The invention discloses a device for restraining the vibration of a high-speed rolling mill by reducing the speed fluctuation of a rolling inlet of an aluminum foil. A frame is arranged at the front end of the mill equipment and at the rolling inlet of the aluminum foil. Two guide rollers and a tensioning roller are arranged in the frame, wherein the two guide rollers are mounted at the upper part of the frame; the tensioning roller is mounted at the lower part of the frame and between the two guide rollers; a small gear is mounted on a roll neck at one end of each guide roller; a big gear is mounted on the shaft neck of a flywheel; the flywheel is mounted in a flywheel mounting groove in the outer side of the frame; and the small gear on each guide roller and the big gear on the flywheel are matched in a gear engaging manner. The device provided by the invention has the advantages of simple mechanism structure and easiness in maintenance and repair, and has a good effect of restraining the speed fluctuation of the rolling inlet of the aluminum foil.

Description

technical field [0001] The invention relates to a device for suppressing chatter of a high-speed rolling mill during aluminum foil rolling, in particular to a device for reducing fluctuating entry speed of aluminum foil rolling and suppressing chatter of a high-speed rolling mill, which belongs to the technical field of rolling vibration reduction. Background technique [0002] During the high-speed rolling process, the surface quality defects of rolled aluminum foil products caused by the chatter of the rolling mill, such as the vibration marks of rolled products, are common problems in the production of rolled aluminum foil, and are also a technology that plagues the rolling industry worldwide. problem. Vibration marks refer to the light and dark stripes formed on the surface of rolled products. The occurrence of vibration marks not only affects the quality of rolled products, but also the severe chatter of the rolling mill can cause broken belts or equipment damage accide...
