Rolling is the process involving plastic deformation of metals by squeezing action as it passes between a pair of rotating rolls. To control the relative positioning of rolls, a roll positioning system is employed on the mill stand, generally through hydraulic pressure. The most common rolling mill is the 2high rolling

The new X6h mill has better stiffness characteristics than the other two types of mills. Furthermore, the structure of the X6h rolling mill could be optimized based on an optimization theory, and on the basis of satisfying the requirements of stiffness and stress. The lightest roll system structure is recommended to design a good rolling mill.

The present investigation devices a novel Xtype sixhigh (X6h) mill. In addition, parametric models of different roll layouts such as the fourhigh (4h), Itype sixhigh (I6h), and X6h mills are established. Threedimensional (3D) finite element (FE) contact analysis for a strip rolling process is conducted when the mills are subjected to a constant vertical load of 65 kN.

The more roll pairs the mill has, the greater the size reduction it can achieve. For instance, reducing salt feedstock to coarse road salt requires a roller mill with one roll pair, while reducing the material to table salt requires a mill with two or three roll pairs.

The operation of the world's first multimode continuous casting and rolling F3 (3rd finishing mill stand) finishing mill was hampered by frequent vibrations. Mill vibrations were found to be caused by the transmission and coupling of vibration energy flow. In this study, an overall finite element model of the F3 stand is established based on the structural sound intensity method and harmonic ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its crosssectional area.. The types of rolls used in rolling mills are depended upon the shape, size, and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...
