摘要： A chattering detection method for a cold rolling mill, the method including: measuring a vibration of a cold rolling mill; calculating a time waveform of vibration intensity by performing frequency analysis on a time waveform of the measured vibration of the cold rolling mill for a predetermined period equal to or shorter than a time in which a periodic vibration continues without converging; and detecting a chattering sign vibration of the cold rolling mill based on a number of points having vibration intensity values that exceed a predetermined threshold, the points being included in the calculated time waveform of the vibration intensity.

摘要： The invention relates to a method for detecting the vibrations of a roll stand (1) equipped with a hydraulic jack (6) as a device for adjusting the rolling rolls (4, 5). The hydraulic jack comprises a sensor (64) for measuring the position of the mobile portion relative to the fixed portion, this sensor supplying a digital signal (POS). In the method of the invention, the vibrations are detected by direct observation of the position signal (POS) and a comparison thereof relative to a spatio-temporal window (F) whose dimensions are determined as a function of the frequency to be detected. In accordance with the invention, it is possible to define different observation windows (F) suitable for the detection of different vibratory phenomena. In a tandem mill, the position signal (POS) of the hydraulic jack (6) of each roll stand (1) is observed in accordance with the method of the invention, which enables the commencement of vibration on each of the stands to be detected and the stand on which the phenomenon started to be determined.

摘要： Hydraulic cylinders are provided in a housing so as to be opposed to work rolls and backup rolls. Before a front end portion of a rollable material is engaged between the work rolls, the working oil pressure of the hydraulic cylinders is set at a high pressure value to make a pressing force on roll chocks high. After the rollable material is completely engaged between the work rolls, the working oil pressure of the hydraulic cylinders is set at a low pressure value to make the pressing force on the roll chocks low.

摘要： When rolling steel sheet and other rolled stock, rattling occurs in certain operating states. This results in reduced quality of the rolled stock and rejects as well as damage to the rolling mill. No improvement was achieved by placing brakes on the cylinders. Electronic monitoring is not a satisfying solution. Given that rattling is a self-starting oscillation, resistance sensors are coupled to the cylinders and/or the rolled stock in order to stabilize the self-starting oscillation modes, modes with negative damping, by means of additional damping. In the example illustrated in FIG. 4, cylinder-shaped, rotating dampers are coupled to the working cylinders. Concentric or disc-shaped layers made of steel and plastic such as those found in layered oscillation absorbers are most effective and adaptable. The arrangement of the working cylinder and the damper illustrated in FIG. 4 makes it possible to suppress vertical (nullx1 direction) oscillations and the self-starting rattling oscillations in x2 and null5 direction responsible for the thickness and form waves caused by rattling in the rolled stock.

摘要： A system for controlling vibration of a dynamic surface includes at least one sensor in communication with the dynamic surface for measuring vibration of the dynamic surface and generating a feedback signal proportional to the measured vibration and at least one piezoelectric actuator in communication with the dynamic surface and in communication with the controller for receiving the output signal. The system also includes at least one mass overlying the at least one piezoelectric actuator, whereby the at least one piezoelectric actuator lies between the mass and the dynamic surface, and a controller in communication with the at least one sensor for receiving the feedback signal, generating an output signal in response to the feedback signal and sending the output signal to the at least one piezoelectric actuator. The piezoelectric actuator applies a counter force between the dynamic surface and the mass upon receiving the output signal for reducing or controlling vibration of the dynamic surface.
