Abstract—A new method of rolling rails on universal rail-rolling mills equipped with a continuously reversible group of stands is discussed.A relation is obtained to calculate the slopes of the lateral faces of the horizontal rolls in universal four-roll passes, including a prefinishing pass, as functions of the slopes of the corresponding lateral faces Kim et al. (2012) analyzed the cause and characteristics of the chatter vibration in a six-high cold rolling mill by using multibody dynamics. However, it is difficult to incorporate coupling effects and interactions between stands in FEM model. Based on state-space methods, Hu et al. (2006b, 2006c) investigated mill stability in both singleDynamic analysis of vibration stability in tandem cold rolling mill

The rolling of rails in universal stands on modern rail rolling mills equipped with continuously reversible groups of stands is carried out in different ways but at a constant slope of the inner flanges of the section (lat-eral faces of horizontal rolls) in universal passes [11]. Under such rolling conditions, the absolute com-Abstract. The SKI effect is a serious problem occurring during the rolling of metal sheets in plate mills. This term stands for the vertical bending of the workpiece front edge at the stand output. The downward bending results in strikes as the workpiece is moving along the table rollers, leading to its jamming and emergency stops of the mill.Technological Causes of Vertical Workpiece Asymmetry in Plate Rolling Mills

A new two-stands S6-High rolling mill, designed for highest quality standards, has been installed at the entry section of the Hot Annealing&Pickling line LAC10 of Acciai Speciali Terni S.p.A., in order to reduce the thickness of the incoming hot rolled strips to produce new products and to serve new range dimensions for the following of which (one break-down and two section stands) are three-high mill stands and one is a two-high mill stand. The roils of the break-down stand 500 mm in diameter and with a length of the barrel 1700 mm are made of steel, have The controlling roll pass is a vertical roll pass.

Four high rolling mills; Cluster rolling mills; Planetary rolling mills; Tendem or Continuous mills; 1. Two High Rolling Mills. It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the roll isoverall mill length but its vertical stands are still 20 ft-6 in high. Andfor the samereasons, ahot strip mill with drive-free edging rolls between finishing stands has been ex-aminedrecently. 2) Acontinuous rolling mill with drive-free vertical rolls was developed.3) In this mill, the horizontal and vertical stands are alternately disposedCharacteristics of Rolling in Contlnuous Billet Mill with

Universal rolling mill stand (10) which comprises a pair of upper (30) and lower (31) rolls having a horizontal axis and defining a rolling plane (13), the rolls (30-31) being complete with their relative chocks (28-29), and comprises also at least one roll (42) having a vertical axis and cooperating with the rolling plane (13), the roll (42) with the vertical axis A wear model was developed to predict the roll wear profile at different stands of a finishing mill. The wear behavior of finishing mill (stands F4) work rolls was analyzed experimentally. A box type wear pattern with sloping wall was observed. Comparatively higher irregularity was observed for stand F4.IOP Conference Series: Materials Science and
