Fig 4 Roll configurations in rolling mills. Two-high mill roll configuration – This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the …
Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls …
Four-High: A 4-HI mill may be used for finish rolling of thin gauge stock. 6-HI roll inserts are also available for narrow width ribbon and foil products. Combination: A combination rolling mill is a versatile "two-in-one" type of metal rolling mill …
Product description. 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.
Product description. The 4-high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip. Either the work roll or the back-up roll is driven, depending on customer requirements. The diameter of the 4-high work rolls amounts to approximately 1:4 in relation to the barrel length.
The 4 hi rolling mill also has an increase in the roll train, so the roll diameter of the work can be much smaller, and the corresponding rolling force is much smaller. It is more suitable for rolling thinner materials, then the whole …

20-HS mill rolling mills from SMS Group - technology that pays off. You benefit from our 20-high mills because they are packed with state-of-the-art mechanics, hydraulics, electrics, and automation. Plus: it's easily possible to retrofit these features into existing mills.
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 equipment, rolling …
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.
