Chatter detection in a five-stand cold mill^*

Détection du broutage sur un train à froid 5 cages

J.C. Groothuizen, L.J. van Egmond and G. van Steden

Abstract

In high speed, cold mill mechanical vibrations generate chatter. This defect is to be avoided to prevent the production of unacceptable sheets and damages to the mill components. The so-called chatter of the third octave mode results in severe gage variations. The chatter of the fifth octave mode develops marks on the rolls. Hoogovens has studied those defects by means of accelerometers on the 4th and 5th stand recorded by an analog recording device. An early warning system has been developed and tested for more than one year.
