Metal Rolling Manufacturing Process

Blooms typically have a square cross section of greater than 6x6 inches. Slabs are rectangular and are usually greater than 10 inches in width and more than 1.5 inches in thickness. 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

Investigation of roll bite behavior with various cold

only to a specific rolling condition which agrees with the imposed assumptions. For instance, Sims'[2], Blandand Ford's [3], and Robert's [4] equations have been applied broadly in hot mills, cold mills, and temper mills respectively. Later, Fleck and Johnson proposed a socalled "double dip" contact arc to solve the foil mill problem [5]. Continuous efforts by them and their

Analysis of Chip Generation During Bar Rolling .

03.04.· Bar rolling is a semicontinuous rolling process involving a series of rollers, where a cast billet is shaped into the final TMT bar. In these mills, lowthickness bar rolling (< 20 mm) is prone to cobbles, due to several operational reasons, which affects productivity. One major contributor is blockage of slitters and notwist mill grooves due to excessive chip formation from the rolled bars.

Hot rolling mill process and hot rolled steel .

Hot rolling mills typically produce sections of steel at various dimensions from billets of steel. The manufactoring process involves passing bars of steel at high temperatures. This happens through rotating rolls to reduce the thickness and shape the sections. It furthers proceeds into cooling and cutting to length or coiling into rolls for transport to other finishing processes such as cold
