Abstractβ According to research tests, the rollinganddrawing of metal in nondriven rollers reduces the rolling force by 30 to 32% as compared with the rolling in driven rollers. A new method of determining the friction coefficient for a modified process flow sheet is proposed. As shown by the calculations, continuous strip mills used in the rollanddraw mode cut the metal strain force by ...

The advantages of Rolling process are as follows. By rolling, uniform dimensions of the components can be obtained. It uses the same tool in the sense, the same rollers are responsible for the production of various components. Close tolerance is possible for the components in the rolling. highspeed production takes place in the rolling.

Rolling is the process of plastically deforming metal by passing it between the roles. The rolling process is basically used for reducing the crosssectional area of the metal stock. (The width is the same but there is a significant reduction of thickness). It is the most widely used forming process and it provides high production with very ...
