Metal Rolling

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 ....

Rolling (metalworking)

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 (I-beams, angle stock, channel stock), bar stock, and rails Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products...

Cold Rolling Mill

A major steel producer was not satisfied with the performance of the four-row tapered roller bearings that were installed in its cold rolling mill: steel shavings from the production process were getting into the bearings and having a detrimental effect on reliability...

Narrow Steel Strip

Liberty Speciality Steels Narrow Strip mill has a long-established reputation for providing precision strip products These are tailored to meet the needs of cold-rollers and customers in many market sectors including: automotive, aerospace and general engineering for applications such as: saw blades, keys, razors and industrial needl...

The Hot Rolling Process

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...

Hot Strip Mill

John G Lenard, in Primer on Flat Rolling (Second Edition), 2014 21 Hot Strip Mill Evolution Hot strip mills have evolved in various steps from original tinplate and sheet rolling mills The development of semi-continuous and continuous multi-stand mills followed, producing small-diameter and eventually large-diameter steel coil products...

How does it work: hot

Mar 31, 2015· ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot-strip rolling mill in Duisburg The animation shows how it all works...

Cold Rolling

Cold rolling reduction is an important factor that affects drawability of IF steel It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34]This effect has been shown in Fig 514Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35]...

Hot Rolling Mill

Continuous casting

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots Since then, "continuous casting" has ....

Optimization of a Cold Rolling Mill

strip will handle the tons of pressure and tensions of the high speed rolling process Table I summarizes the typical thicknesses and rolling speeds for each mill type Not surprisingly, as the material gets thinner, the speeds increase dramatically Hot Roughing Mill Hot Finish Mill Cold Rolling Mill Maximum Thickness >400 mm 20-50 mm 3-20 mm ....

Cold Rolling Mill

Cold rolling is accomplished by processing steel strip through a series of tandem rolling mill stands Each stand has vertically stacked rolls that are powered by huge motors to impart high compressive stresses into the strip Hot-rolled, pickled coils are fed into the cold rolling mill from an entry-...
