Vibration suppression device for rolling mill

Abstract

The invention relates to the technical field of rolled metal, and particularly discloses a vibration suppression device for a rolling mill. The device comprises a working roll mechanism and a supporting roll mechanism, wherein the working roll mechanism is arranged between a movable block and a fixed block of the rolling mill; the working roll mechanism comprises a first fixed wedge-shaped slidingplate, a first movable wedge-shaped sliding plate, a first fixed rectangular sliding plate and a first hydraulic cylinder; the first fixed wedge-shaped sliding plate is fixedly connected to the fixedblock of the rolling mill; the first fixed rectangular sliding plate is fixedly connected to the movable block of the rolling mill; the first movable wedge-shaped sliding plate is located between thefirst fixed rectangular sliding plate and the first fixed wedge-shaped sliding plate; and the first hydraulic cylinder is fixedly connected to the fixed block of the rolling mill. The vibration suppression device is simple in structure, easy to implement, high in pertinence and completely feasible in application and promotion. The vibration suppression device can effectively suppress the abnormalvibration of the continuous mill in the rolling process and reduce harm, and is of great significance in the aspects of improving the production efficiency of enterprises, prolonging the service lifeof equipment and the like.

Description

technical field [0001] The invention relates to the technical field of rolling metals, in particular to a rolling mill vibration suppression device. Background technique [0002] Due to market demand, companies are stepping up research and development and production of thin gauge (0.8-2.1mm) high-strength steel plates, while the rolling mills of the original companies are designed and produced according to ordinary steel plates, which frequently occur when rolling high-strength steel plates The phenomenon of horizontal vibration of the rolling mill. The horizontal vibration of the rolling mill not only damages the mechanical equipment and electrical control equipment, but also affects the shape, thickness and surface quality of the strip products, causing rapid wear of the roll surface, and even causing production accidents such as broken strips and stacked steel in severe cases. [0003] So far, there have been 165 sets of hot-rolled strip production lines with a width of ...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to aim at the limitations of existing devices for suppressing abnormal vibration of rolling mills, and discloses a device for suppressing vibrations of rolling mills. The gap between the work roll, the back-up roll bearing seat and the archway column is easy to implement modification and consumes less money, and has broad application prospects
