These backup rolls are larger and contact the back side of the smaller rolls. A four-high mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils.
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.
The bale of forged rolls and rolls which are not composite casted are hardened on the periphery. Basi-cally a distinction is made between work, intermediate and back-up rolls. Work rolls for hot mills are mostly manufactured of compo-site cast through centrifugal casting processes. Most com-n materials for roll bales in hot mills are indefinite ...

block cast or forged roll with the conventional rolling mill. Some of the designs used for composite rolls are epoxy bonding 3, 4, Belleville spring 5, and intermediate tapered sleeve 6, 7. At present there is a definite need for providing roll-locking unit in a composite roll for rolling metal billets and to provide an improved composite roll. In
Under the most suitable condition, cylindrical composite roll sleeve could be produced, which had homogeneous microstructure dispersed fine carbides, uniform hardness distribution in the whole HSS layer and defect-free bonding zone. The composite rolls were applied to actual hot rolling.

The problems rolling-mill rolls had at the time were "the short rolling pitch, which was compromised to improve productivity, and the increasing heat-load to the exterior surface of the roll." In 1988, invented the HIP Shaping Composite Ring Roll for steel bar and section mill, which was 10 times more durable than conventional rolls.

Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
Rolling Tools Composite Roll. Solid rolls are essential to the iron and steel industries. The heat-resistant and deform resistant cemented carbide can mill steel heated to approximately 1000ºC. This contributes to the high-efficiency rate in the production of steel.

Available in ceramic (silicon nitride): - Guide and pressure rolls (ready to use) can be supplied in a range of outer diameter D = 30 to D = 180 mm.
Rolling processes 5-1 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 (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
