METALLURGICAL APPLICATION TO WORK AND BACK UP .

 · Rolling mills are increasingly demanding rolls capable to maintain the shape and profile much longer with the aim to extend the length of campaigns. The state of the surface is one of the criteria determining the roll change. With the aim to satisfy the mill requirements it is necessary to pay attention to the Kinetic of oxidation, hot hardness increase in the matrix and the morphology of the ...

 · Rolling works on same as any other metal forming process. When a compressive force applied by a set of rolls on ingot or any other product like blooms or billets, plastic deformation takes place which decrease its cross section area and convert it into required shape. These rolls are designed according to the final product requirement. They are cylindrical in shape and fitted with the die of ...

The predictions of the model are verified using mill trials under industrial conditions. For both thin strip and foil, the load predicted by the model has reasonable agreement with the measurements. For rolling of foil, forward slip is overestimated. This is greatly improved if a variation of friction through the bite is considered. DOI: /# 1 Introduction There is an ...

Rolling Circles. The circle rolling is the main process of product forming, which is divided into one feed and multifeed process. The number of feed times depends on the process (such as the cold roll is not allowed to exceed the allowable maximum deformation rate) and the equipment constraints (such as nonslip conditions and power conditions). A certain amount of overwinding must be added ...

The rolling mills can be easily classified according to the number of rolls present and the kind of arrangement in which they are performing the rolling operation. The basic arrangements are as follows Two High Rolling Mill This is the simplest and most common arrangement of all. In this the rolls are of same size and are made to rotate in same direction. The metal is passed through the ...

 · The rolls are equipped with bearings and mounted in a stand with a screwdown mechanism. A force applied to the rolls in vertical direction is called roll separating force. A rolling mill is characterized by the maximum values of its roll separating force and the torque. The maximum amount of deformation (thickness reduction) which may be achieved in a single rolling pass is determined by the ...
