Then, as the cold mill gap is adjusted to reduce the crown, the coil also will come out flatif the hot mill got the relationship between crown and flatness right to begin with. If the cold mill rolls or hot mill coils have too much crown, the mills will roll out the center, creating center buckle in the process (see Figure 8).

The rolling process is a metalforming process, in which a stock of the material is passed between one or more pairs of rollers to reduce and maintain the uniform thickness. This process is mainly focused on the crosssection of the ingot or the metal which is forming. Using this process, we can reduce the thickness of the metal workpiece.

The unsteady lubrication is one of the major causes for selfexcited vibration in rolling. But it is difficult to build a rolling chatter model which considers the unsteady lubrication state in roll bite. Using the regression exponential function model of rolling friction coefficient, a dynamic rolling process model was built. Coupling the dynamic rolling process model with a mill stand ...

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 ...

Cyclic temperature changes in the working layer of a roll during hot rolling cause thermal stress which leads to damage on the surface layer of the roll due to thermal fatigue. The preconditions of crack initiation are described. The intensity of crack propagation could be influenced by optimizing the chemical composition and physicalmechanical properties of the material on the working layer.
