Rolling of Metals

Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating

12.5 Iron And Steel Production

The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages

Design of Forming Processes: Bulk Forming

quasi-static-flow process. The bulk deformation process of forging is an example of a continuous-flow process. As the metal is being shaped in the forging die cavity, the deforming region, which is often the entire amount of metal, is continuously undergoing change. Processes such as rolling, wire drawing, and extrusion are exam-


During the process of cross rolling the rolls are rotating in the same direction. The billet is fed in axial direction and it re-ceives the rotational movement contacting the rolls. The billet is retained in rolls by special device during the process of rolling and reducing by rolls. The sections being the bodies of …

Rolling Process for Steel - Steel casting foundry USA

Steel undergoes the process of rolling to reduce the thickness of the metal as well as make it uniform. In this process, steel is placed between two rolls where the thickness is altered by manipulating the length direction of the steel rather than the width direction. This is because the point of contact between rolls along the length is much ...
