【 摘 要 】

Each system (stand – driving) and the continuous rolling line to which it belongs have its own functional and energetically parameters. To reduce any faults of the strip surface it is also necessary to check (eventually having a control line) the roll surface quality, the work roll eccentricity, and depending on the disposal by compensation, of eccentric lobes. The appearance of the specific faults on the rolled strip-during the experiments carried out is duet o the vibrations covered by the range of 100-300 Hz. This many-sided theme needs mathematical patterns to correlate the factors and the dimensions (strip types, technological flow, driving) which should be able to basically support the monitoring system. Taking into account the aspects regarding the quality of the surfaces, the geometry of strips and the costs, it necessary to do a monitoring.
