Abstract (en)
[origin: WO0224362A1] The invention relates to a four- or six-high rolling stand for a rolling train and to a method for operating the same. The aim of the invention is to provide rolling stands that can adapt rapidly to rolling products of different thicknesses and/or hardnesses. To achieve this, rolling stands are provided with minimum expenditure that can be selectively operated with both thin and thick working rolls. The inventive combined drive in the four- or six-high rolling stand allows thick working rolls to be directly connected to a motor, whereas thin working rolls are merely carried along by neighbouring back-up rolls or intermediate rolls by means of friction.
