On the second rolling mill, the semi-high-speed steel work rolls were peeling off (Figure 12a), located at a distance of 650 mm from the edge. The diameter of the work roll WR when peeling occurs is 1155mm, and there is still 30mm from the scrap diameter, and there is …
In hot rolling mill during the metal rolling at finishing mill (4-Hi mill Reversible), work roll pair come out due to the axial crossing of work rolls and due to which uneven thickness of metal, strip breakage, bending of locking plate, metal shifting and equipment breakdown occurs.
The diameter of the 6-high work rolls amounts to approximately 1:4 in relation to the barrel length. In comparison to a 4-high mill stand, the utilization range is wider. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths.

Rolling mills may be classified according to the number and arrangement of the rolls. There are five main types: 1.Tandem rolling mills. 2. Cluster rolling mills. 3. Two high rolling mills. 4. Three high rolling mills. 5. Four high rolling mills . Tandem rolling mills . It is a set of two or three stands of roll set in parallel placement.
The roll surface is crucial for work rolls in hot rolling mills. We have to deal with wear, oxidation, firecracks, sticking and friction. This paper starts with temperature simulations on and below the roll surface during rolling and takes common experience into consideration.
The forged rolls are widely used on some tough stands of hot rolling mill, such as BD stand and blooming stand to perform with excellent strength to avoid some rolling accidents. Meanwhile, it is also a good choice to work on the cold rolling mill as backup roll and work roll.
20 High Cluster Mills utilize small diameter work rolls which allow higher reductions on harder materials than other mill configurations. The multi-roll system having employs a unique roll configuration with adjustment capabilities to control strip shape and compensate for the effects of rolling a wide range of different strip widths to very thin thicknesses.

Work Roll. A rolling mill is a machine tool that passes heated or normal-temperature metal through two rolls and transforms it into diverse shapes. A work roll is a core part of a rolling mill that enters into direct contact with rolling material to make cold rolled carbon sheets (CR) of the desired thickness.
In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.
