A rolling mill vibration suppression device

Abstract

The invention relates to the technical field of rolling metal, and specifically discloses a rolling mill vibration suppressing device, which includes a work roll mechanism and a backup roll mechanism. The work roll mechanism is arranged between a moving block and a fixed block of the rolling mill. The work roll mechanism includes a A fixed wedge-shaped slide plate, a first movable wedge-shaped slide plate, a first fixed rectangular slide plate and a first hydraulic cylinder, the first fixed wedge-shaped slide plate is fixed on the fixed block of the rolling mill, and the first fixed rectangular slide plate is fixed on the rolling mill On the moving block, the first movable wedge-shaped slide plate is located between the first fixed rectangular slide plate and the first fixed wedge-shaped slide plate, and the first hydraulic cylinder is fixedly connected to the fixed block of the rolling mill; the rolling mill vibration suppression device of the present invention has a simple structure , easy to implement, highly targeted, and fully feasible to promote and apply. On the other hand, the present invention can effectively suppress the problem of abnormal vibration in the rolling process of the continuous rolling mill, reduce the damage, and has great significance in improving the production efficiency of the enterprise and increasing the service life of the equipment.

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
