    摘要: 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.

    摘要: The invention relates to a rolling mill for sizing tubes or cylindrical bodies such as bars, rods and so on, and is intended for the iron and steel industry. The rolling mill is made up of a multiplicity of fixed three-roll rolling units, i.e. of the type known per se in which the position of the rolls cannot be adjusted under load and they are kinematically connected to each other so as to be set in rotation simultaneously, downstream of which are a multiplicity of adjustable three-roll rolling units. In the latter units the position of the rolls can be adjusted even under load and the purpose of these is to carry out the finishing of the work that is to be sized. The invention enables excellent use to be made of the characteristics of strength of the fixed units and of accurate working of the adjustable units, with the result that it is possible to build an inexpensive but high-performance rolling mill. In a preferred embodiment, in the adjustable units the rolls are mounted on lever-type arms pivoting in planes lying radially with respect to the rolling axis.
