There are various designs of mill stands each having different applications to the rolling process. All the rolling mills have rolls for the rolling of materials which are fitted in the roll stands. Roll stand configurations for the most common types of hot rolling and cold rolling mills are described below and shown in Fig 1.

HSS rolls, often installed in the earlier stands of hot strip mills, provide improved wear resistance along with a better surface roughing resistance. However, HSS are rolls more sensitive during operation and require a higher grade of attention with regard to roll cooling than High-Cr rolls.

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 ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …

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.

STECKEL MILL — SPECIALIZED SOLUTIONS THROUGH ENGINEERING EXPERIENCE The Steckel Mill occupies a special niche in hot flat rolling, operating at a lower economic volume than tandem hot strip mills but capable of greater widths and especially suitable for particular alloys, including stainless steels.

• Rolling –reducing the thickness or changing the cross-section of a long workpiece by compressive forces applied through a set of rolls • Developed in late 1500s • Accounts for 90% of all metals produced by metal working processes • Often carried out at elevated temperatures first (hot rolling) to change coarse-grained, brittle, and ...

Hot rolling is among the most widely used manufacturing techniques. However, rolling mills are major resource consumers; thus, urgent rationalisation is required in the relevant industrial systems. Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is important to optimise …

design. Hot rolling permits large deformations of the metal to be achieved with a small number of rolling cycles. Heating of Cold Stock One of the prequisites of the hot rolling practice is heating the input bloom/billet/slab from the room temperature to the rollable temperature. At that higher temperature the steel is transformed in to a
