Rolling Hot Process

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. If these products came from a continuous castingoperation the products are usually fed directly into the rolling mills at the proper temp…

The Hot Rolling Process - California Steel Industries

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

So tolerance for the shape at the hot rolling process is rather high. On the other hand. The cold rolling process is carried out at low recrystallization temperature and it produces relevant small and thin pieces and temperature is low, therefore deformation becomes relatively difficult than the hot rolling process.

Hot Rolling - an overview | ScienceDirect Topics

The hot rolling of strands to wire 5.5 mm in diameter comprises five main processes: conditioning of the input (scarfing, grinding), heating to rolling temperature, descaling, rolling down to the final diameter and finishing (trimming, slitting, cutting). LCI information on the hot rolling process was taken directly from Althaus et al. (2004).

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.

Rolling | technology | Britannica

Rolling may be done while the steel is hot (hot-rolling) or cold (cold-rolling). The process consists of passing the metal between pairs of rollers revolving at the same speed but in opposite directions and spaced so that the distance between them is slightly less than the thickness of the metal.

Hot Forging - an overview | ScienceDirect Topics

Hot forging can be defined as “a metal shaping process in which a malleable metal part, known as a billet or workpiece, is worked to a predetermined shape by one or more processes such as hammering, upsetting, pressing and so forth where the workpiece is heated up to about 75% of its melting temperature”. The process begins with a cast ingot, which is heated to its plastic deformation ...
