Beschreibung
Zusammenfassung:	Erroneous detection that occurs due to noise and the like generated from equipment around a rolling mill is prevented, and abnormal vibration is extracted and evaluated with high accuracy.A method for detecting abnormal vibration of a rolling mill includes a collecting step of collecting vibration data of the rolling mill; a frequency analysis step of generating first analysis data indicative of vibration intensities at respective frequencies by performing frequency analysis of the vibration data; a data conversion step of converting the first analysis data into second analysis data indicative of vibration intensities at respective intervals on the basis of a rolling speed; and a map generation step of generating a vibration map in which a plurality of the second analysis data are arranged in time series.
