Abstract: This paper deals with the stability analysis of the lateral plate motion in a reversing rolling mill for heavy plates. Lateral asymmetries in the rolling process can cause a rotation and a lateral motion of the plate in the mill stand. In the worst case, the lateral motion of the plate may lead to crashes of the plate with the mill stand.

Some reversing rolling mills are equipped with edger rolls to control the width of the rolled plate. At best, the straight plate centerline coincides with the lateral centerline of the rolling mill and the desired rectangular shape is ...
In the early years of the eighteenth century, two-roll rolling mill was invented in West Europe, and it could produce small size plates. In 1854, reversing two-roll plate rolling mill driven by steam engine was built in Europe. In 1864, the Lauth three-roll plate rolling mill was built in the United States, and it was quite popular in that period.

Reversing mills are more expensive than non-reversing rolling mills due to their reversible-drive requirement. The purpose of the reversing mill is to reduce the thickness of the steel to the customer's specifications. The hot roll band passes back and forth between the rolls until it reaches the specified thickness. Benefits of reversing ...
