In the cold rolling process of steel strip products, strip breakage is an undesired production
failure which can lead to yield loss, reduced work speed and equipment damage. To …

Severe vibrations, known as chatter, occur often in both hot and cold rolling of steel. A recent
chatter outbreak at the second stand of hot strip mill in Hastings, Australia, prompted an …

Prevention of dynamic instability caused by chatter phenomenon may be difficult in case of
the so-called “cluster mill” because of the number of back-up rolls used to avoid bending of …

The dynamic characteristics in a rolling process have been investigated with various
methods, but a mathematical model to predict actual chatter vibration has not been …

High-speed rolling and high reduction usually are desirable as increase mill productivity in
the cold strip rolling. However, most often, these conditions lead to the creation of chatter …

In this work, the finite-element method (FEM) is used to develop the governing equation of
motion of the working roll of a four-high rolling mill and to study its vibration due to different …

Introduced is a three-dimensional, physics-based mathematical model capable of efficiently
predicting self-excited chatter vibration phenomena in the cold rolling of metal strip and …

The presence of several rolls in cluster cold rolling mills makes on-line vibration monitoring
and failure analysis difficult. The dynamic behaviour of rolls strongly depends on the rolling …

The rolls in contemporary four-high mills cannot be maintained parallel during the rolling
process. Therefore, four-high rolling mill vibrations take place in six degree of freedom …

Introduced is a new physics-based three-dimensional (3D) mathematical model capable of
efficiently predicting time histories of the nonlinear structural dynamics in cold rolling mills …
