    Rolling is defined as a process to form metals where the metal strip is pressed by two or multiple rollers, thus the uniform thickness is formed. To do this, the temperature is essential. In this rolling mill, there are two rolls used. Two High Reversing Mill In this type of mill, the rollers are both adjustable. In these mills on wear is another issue.

    PHYSICAL METALLURGY OF A HSS MATERIAL FOR HOT ROLLING MILL ROLLS Jacqueline LECOMTE-BECKERS 1 Jerome TCHOUFANG TCHUINDJANG 1 Eric PIRARD 2 Jean-Pierre BREYER 3 ABSTRACT High Speed Steel (HSS) cast rolls are used in front finishing stands of hot strip mills. Metal can be reduced by between 60 and 80 percent through cold rolling, and then can be used in the creation of consumer goods or for use in other industries. Can Metals other than Steel Benefit from a Cold Rolling Mill Though cold rolling is most often used on steel, many alloys and metals can be cold rolled to change their crystalline makeup.

Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.

  • Sheet Camber and Cambering of Rolls Metallurgy

    The middle of roll becomes hotter than its ends and hence roll diameter in the middle of roll increases. In hot rolling mills this effect is quite pronounced and should be taken into account while calculating the roll camber. In cold rolling mills the coolant supply at different points on roll surface may be adjusted to minimize this effect. The convex shape of sheet is mainly due to deflection or bending of rolls like a beam. To counter this, camber is ground on rolls in the opposite direction so that after deflection the surface in contact with the sheet becomes flat. However, during rolling a temperature differential builds up in the roll.

    Dec 24, 2018 · Many mill rolls manufacturers provide quality tandem rolling mills to various industries. 5.Cluster Rolling Mills Cluster Rolling Mills is a first four high rolling mills, where each of the working rolls is backed up by two or more larger rolls for rolling hard material. At times, one might need to employ work rolls of minimum diameter. Summing Up HSS is normally rolled in tandem cold mills (TCMs) that employ 4-high or 6-high rolling stands with work-roll diameters ranging from 630 mm to 420 mm. HSS exceeding 980 MPa has been manufactured by extending TCMs with the installation of an additional mill stand.

    Compact in design, CSP ® produces high-quality hot strip in a single manufacturing line that combines casting, heating, and rolling. Our proven CSP ® caster with its patented funnel-shaped mold casts thin slabs in thicknesses ranging from 50 to 90 mm. Next, the slabs go into the CSP ® furnace for temperature equalization. Straight after that, the CSP ® mill rolls them to final strip thickness. Today s rolling mills.
