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： The process is characterized in that, before starting casting, an initialization position is determined for the stopper rod control actuator when the stopper rod is resting on its seat under its own weight and after having filled the tundish equipped with this stopper rod, the actuator is operated to place it in a controlled superclosed position and, to start casting, the actuator is driven according to an imposed movement versus time law, time (t1) for start of casting being determined from this law and the control actuator continues to be driven in opening direction to enable the metal to flow into the ingot mould.
