A reversing mill is a twohigh rolling mill in which the direction of rotation of the rolls can be reversed to allow the work to pass through from either side. Besides flat rolling and shape rolling, identify some additional bulk forming processes that use rolls to effect the deformation.

Some reversing rolling mills are equipped with edger rolls to control the width of the rolled plate. At best, the straight plate centerline coincides with the lateral centerline of the rolling mill and the desired rectangular shape is exactly realized. ... While [5] suggests reducing camber by tilting the roll during the rolling pass, [3], [4 ...
Abstract In plate rolling, reversing roughing mills are commonly used as a first processing step after casting. They are typically equipped with edger rolls for width reduction. During a rolling pass, lateral asymmetries like temperature gradients or thickness inhomogeneities can cause two major problems.
4HI mills with work rolls are offered as small as .500″ ( mm) in diameter. 2HI mills are offered with rolls up to 16″ (400 mm) in diameter. Rolling Mills Offerings Materials Applications Mill Types Laboratory Mills Standard Features Ancillary Options Industries Designed and built to your production requirements
A tandem rolling mill is a rolling mill with two or more closecoupled stands, where the reduction is achieved by the interstand tension (s) and the compressive force between the work rolls. For mills rolling thinner strip, bridles may be added either at the entry and/or the exit to increase the strip tension near the adjacent stands further ...

ANDRITZ highcapacity 4high reduction rolling mills combine 150 years of experience with outstanding features in cold rolling for carbon steel, stainless steel, and other material. Product description The 4high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip.
In the third phase the rolling mills used steam power. Steam power first appeared in the late 1700s because of the invention of James Watt. The steam engine created the physical power which replaced the manual / animal power. The rolling mills of this era harnessed the power created by the steam engines. Steam engines were commonly used for ...
These mills are both nonreversing and reversing types of the rolling mills. Six high mills In six high rolling mills, there are six horizontal rolls, mounted in a single vertical plane. Two rolls (inner) are work rolls and four rolls are backup rolls. ... These types of rolling mills are also called cross rolling or roll forging mills ...
There are tworoll reversing mill, threeroll Lauter mill and fourroll reversing mill in terms of structure. According to the number of stands, there are singlestand, doublestand and multistand semicontinuous rolling or fullcontinuous rolling. ... The finishing stand is a fourhigh rolling mill, and the backup rolls are used to prevent ...
The Hyper UCM is the result of pioneering innovation combined with decades of refinement. It represents the technology of choice for new cold rolling mills but can also be implemented in the context of reversing cold mill and tandem cold mill upgrades. This article examines the development and refinement of the Hyper UCM, and showcases a recent ...
Thrust force of work roll shifting. Fig. 1 shows a fourhigh rolling mill with work roll shifting. When work roll is considered, the thrust force includes the following two parts as shown in Fig. 2: (1) F AWS thrust force is the resultant force of the friction force along the shifting direction of the deformation zone between the work roll and ...
6 High reversing cold rolling mill is the cold rolling production line with designed annual output of 200 thousand tons and adopts UCMtype singlestand mill. It rolls pickled hot rolled coils into cold hard coils. The unit is equipped with hydraulic AGC. The work roll is equipped with positive and negative bending and subsection cooling.

The first mill is a large bar mill (LBM) that rolls blooms into finished large round and square products, as well as into intermediate billets. A 2high reversing breakdown stand is followed by a finishing and sizing train with continuousgapadjustment stands equipped with an underload rollparting system for automatic gap control.
The versatile Waterbury Farrel 4Hi Mill can be deployed as both a nonreversing mill for intermediate rolling and as a reversing mill for finish rolling. Smaller work rolls allow for more efficient material reduction.
a vertical roll stand and two horizontal fourhigh stands, on which rolling is done by the reversing method. When the stock is fed to the roughing stand, and the band is fed to the finishing stand of the Plate Rolling Mill, the neutral axis of the stock or band is, in the majority of cases, does not coincide with the neutral axis of the roll ...
