Rolling (metalworking) - Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

The Ring Rolling Process :: Total Materia Article

The process and equipment are similar in principle to rolling mills used for plate production. Indeed in both processes the metal is rolled between two rolls which move toward each other to form a continuously reducing gap. In ring rolling, the rolls are of different diameters and geometries. The ring rolling process is basically used in the production of railway tyres, anti-friction bearing ...

Rolling processes - Al-Mustansiriya University

Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required. Hot-rolled metal is generally free of residual stresses, and its properties are isotropic ...

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high load. This means that necks should not experience ...

Metal Rolling - Manufacturing Process

During the rolling process great forces act upon the rolls. Rolls will be subject to different degrees of deflection. In any particular metal rolling process, it is important to understand how these deflections will affect the rolls and hence the work being rolled. The rolls initially start out flat. During a basic flat rolling operation, it can be observed that the work material will exert ...
