Tandem cold rolling mills are comprehensive dynamic systems coupling with structure and
rolling technology. A frequent problem is mill chatter, often occurring when rolling hard, thin …

To reveal the impact of vertical nonlinear vibration on the stabilization of the precision cold
rolling system, the vertical nonlinear vibration model with consideration of structural gap and …

The vibration of rolling mill in rolling process and its harm to rolling equipment have become
an international problem in steel rolling industry. The essence of the vibration behavior of a …

This paper investigates the stability of horizontal nonlinear vibration of four-high cold mill
under the effects of gyro-precession and eccentricity between rolls. The threshold value of …

Chatter is a major problem that restricts production efficiency and product quality in the cold
rolling process at high speed. Although many research studies have focused on relating …

The friction characteristics of rolling interface play a considerable role in rolling stability. In
this work, vertical vibration speed is introduced into the Kármán equation. An unsteady …

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 paper, the chattering phenomenon in cold rolling is investigated in reference to the
finite element method (FEM). The structure of the mill stand is modeled as a system of linear …

High rolling speed and high reduction are the optimal conditions for increasing the
production in the cold strip rolling process. On the other hand, increasing the rolling speed …

The interstand tension coupling effect and strip gauge variation passed on to next stand with
time delay are the main causes for regenerative chatter in tandem rolling mills. To study the …
