Rolling of Metals Process and Principles (With Diagram)

The rolling process is shown in Fig. 2.1 Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

Metal Rolling thelibraryofmanufacturing

Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing

Roll Form Design Roll Forming Design

A good rule of thumb is to try to design all roll passes to self-feed even when running coil stock. The mill operator should not have to feed a new coil and "pry" the section into the next pass. *NOTE If end-flare is a concern and a "finish pass" is desired, consider adding two more passes to this ten pass example.
