A system and method for suppressing vibration of a strip mill roll system based on hydraulic cylinder control

Abstract

The invention discloses a plate-strip rolling mill roll system vibration inhibiting system and method based on hydraulic cylinder control. An acceleration sensor (1) is arranged at the bottom of a hydraulic cylinder rigid body (3). A temperature sensor (2) is arranged on a side of the hydraulic cylinder rigid body (3). The hydraulic cylinder rigid body (3) is connected with a temperature adjuster (4). The temperature adjuster (4) is connected with a comprehensive control device (5). According to the invention, related technique for roller vertical vibration inhibition is realized through performing control over oil temperature of a hydraulic cylinder of a rolling mill screwdown gear and a rolling vibration inhibition closed-loop system combining hydraulic cylinder oil temperature and roll system vibration parameters are proposed based on theoretical study and field practice, help is provided for solving rolling mill vertical vibration problems. The system is simple in structure and can realize a rolling mill roll system vibration inhibiting device achieving mutual feedback adjustment of vibration and temperature conveniently and quickly.

Description

technical field [0001] The invention belongs to the technical field of rolling mill equipment, and more specifically relates to a strip mill roll system vibration suppression system based on hydraulic cylinder oil temperature control. The invention also relates to a vibration suppression method using the device. Background technique [0002] Cold-rolled sheet has a wide range of applications in the industrial field. With the development of society and the continuous improvement of manufacturing level, the demand for high-quality sheet based on high-speed, high-precision rolling process is also increasing. For more than half a century, rolling mill vibration has been an important factor affecting the rolling process, seriously affecting the efficiency and quality of steel production. The vertical vibration of rolling mill roll system is one of the main vibrations, which will cause vibration marks on the surface of strip steel and rolls, affect product quality, accelerate roll...

AI Technical Summary

Problems solved by technology

This method can suppress the vibration of the roll system of the rolling mill to a certain extent, but it does not take into account the influence of the oil characteristics of the hydraulic cylinder on the stability of the hydraulic cylinder, so there are certain defects, which make the error of the control effect too large
