Rolling processes 51 introduction: 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 (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
tandem rolling mill or continuous rolling mill: tandem rolling mill process. It is a modern rolling mills and the rolling is done by one pass. The rolling is done in several passes for traditional several stands and reduction that take place successive roll. The number of stands like as 2 to 18. Those are either hot or cold rolling mill types.
Jun 19, 2017· The final dimensional quality of the rolled product is determined by the rolling stands within the finishing mill. The dimensional accuracy in the final product depends on many factors including the initial stock dimensions, roll pass sequence, temperature, microstructure, roll surface quality, roll and stand stiffness and the stock/roll friction condition.

Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (Ibeams, angle stock, channel stock), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semifinished casting products into finished products.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished 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.
Rolling mills which use the "cold rolling" method can process the most tonnage from the entire range of cold working processes.
