Based on the analysis of the influence of roll vibration on the elastoplastic deformation state of a workpiece in a rolling process, a dynamic rolling force model with the hysteresis effect is established. Taking the rolling parameters of a 1780 mm hot rolling mill as an example, we analyzed the hysteresis between the dynamic rolling force and the roll vibration displacement by varying the ...

Fourhigh rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.

A 200mmwide strip is cold rolled by a twohigh mill in thickness from 2 to mm, without any spread. The rolls are 300 mm in diameter and operate at 100 rpm. If the rolling load is MN, determine the mill power required for this cold reduction, assuming typical value of lever arm ratio for cold rolling.

Heated slabs are rolled through one stand at a time to produce socalled transfer bars suitable for finish rolling. Highpressure waterjet nozzles clean the oxidized iron, or scale, from the surface along the way. As the transfer bar exits the last roughing mill stand, the thickness of the leading edge of the bar is estimated.

1. Introduction. The production process of hot rolled flat steel products consists of multiple steps. After casting, the steel slabs are reheated and rolled on a roughing mill to get a thickness around 35 final product thickness in the range of mm to 20 mm is then achieved in a tandem hot strip finishing mill [1].Further thickness reductions may follow on a tandem cold rolling mill.
