Device and method of restraining torsional vibration of high-speed rolling mill based on lubricating of rolled interface and method

Abstract

The invention discloses a device and a method of restraining torsional vibration of a high-speed rolling mill based on lubricating of a rolled interface. The device restraining the torsional vibration of the high-speed rolling mill based on lubricating of the rolled interface structurally mainly comprises rolling mill equipment, a power transmission system, a lubricating device and a signal collecting processing device. Power transmission equipment is connected with the rolling mill equipment by a gearbox and a coupler and provides power for rolling of the high-speed rolling mill. The lubricating device is arranged on a rack of the rolling mill equipment so as to meet the state of a lubricating oil membrane as required in the process of the rolling of the rolling interface and have the function of cooling a roll. The signal collecting processing device is arranged on the power transmission system of a rolling mill. A lubricating state of the rolling interface and an output torque of a driving motor are adjusted so as to achieve the purpose of restraining the torsional vibration, thus greatly reduce emergency frequency of a production accident which is caused due to the fact that the torsional vibration of a main transmission system of the rolling mill is not stable, and take great importance to actual production of a rolled plate.

Description

technical field [0001] The invention relates to a device and method for suppressing torsional vibration of a high-speed rolling mill during rolling, in particular to a device and method for suppressing torsional vibration of a high-speed rolling mill based on rolling interface lubrication, which belongs to rolling lubrication and rolling mill vibration reduction technology field. Background technique [0002] With the development of the iron and steel industry, the number and capacity of various types of rolling mills and their drive motors are increasing, but accidents such as roll breakage, connecting shaft damage, and drive motor rotor parts damage caused by torsional vibration of the drive shaft of the rolling mill It occurs frequently, so for a long time, many scholars at home and abroad have devoted themselves to the research of rolling mill torsional vibration in order to reveal its mechanism, master its law, and then control and utilize it. [0003] The phenomenon o...
