Cluster Rolling Mills; Description of these mills are as follows: 1. TwoHigh Rolling Mills: This type of mill has two types. Those are: Reversing Mills; In reversing Mills; In this rolling mill, there are two rolls used. Two High Reversing Mill: In this type of mill, the rollers are both adjustable. In these mills, rotation of that two rolls is made in two different directions.
x These mills are normally twohigh reversing mills with metres diameter rolls (designated by size). x The objective is to breakdown the cast ingot into

TwoHigh Rolling Mills: The twohigh rolling mill consists of a twohigh stand with two horizontal rolls, placed exactly one over the other. In this type of mill, one or both the rollers are
Various rolling mill configurations are available: 1. Twohigh rolling mill: consists of two opposing rolls. These rolls may rotate only in one direction (no reversing) or in two directions (reversing). 2. Threehigh rolling mill: allows a series of reductions without the need to change the rotational direction of the rolls
Jun 04, 2013#0183;#32;Rolling mills are also classified based on the roll configurations. The types of mills based on roll configurations are given below. Two high mills In this type of mills the rolling stands have two rolls (top and bottom). Three high mills In these types of mills the rolling stands have three rolls which rotate in one direction.
Steel rolled in twostand reversing cold mills is suitable for a wide range of applications, offering the best possible performance in terms of quality and productivity. A twostand reversing cold mill can deliver capacities between 300,000 t/a of thingauge products or 1,000,000 t/a
SMS DEMAG Hot Strip Mills 10 The drumtype shear installed between the roughing and finishing mills of a hot strip mill crops the transfer bar at its head and tail. In special applications, the drumtype shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drumtype shears built so far,
Rolls Specification Of 4 High Reversing Roughing Mill. x The initial hotworking operation for most steel products is done on the primary roughing mill blooming, slabbing or cogging mills. x These mills are normally twohigh reversing mills with metres diameter rolls designated by size.
For the roughing mill (reversible 4high) both roll force and roll torque were available so the friction coefficient could be evaluated in addition to the flow stress for each pass. The values were close to so it was decided to use this for all calculations, also for the finishing, sixstand (4high), tandem mill.
Beam mills, threehigh, rolls from 28 to 36 inches in diameter, for the production of heavy beams and channels 12 inches and over. Rail mills with rolls from 26 to 40 inches in diameter. Shape mills with rolls from 20 to 26 inches in diameter, for smaller sizes of beams and channels and other structural shapes.
rolls specification of 4 high reversing roughing mil. The heart of the temper mill is the cold rolling mill stand which produces the temper pass. It will include electric powered drive motors and speed reduction gearing suited to the process desired. The design of the rolling mill can be a 2high or 4high (even 6high in some cases).
Rolls produced by ESW are up to 9 metres long and their diameter can amount to 1,500 mm. The rolls are given their final measurements and their specific surface through turning, milling and grinding in mechanical processing. Measurement accuracy of the finished rolls is tested to 1/1000 mm.
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. The larger backup roll positioned against the smaller work roll reduces separating forces and permits the rolling of wider and
Two high reversing mill: In two high reversing rolling mills the rolls rotate ist in one direction and then in the other, so that rolled metal may pass back and forth through the rolls several times. This type is used in pluming and slabing mills and for roughing work in plate, rail, structural and other mills.
In a reversing 2high mill, a series of cold rolling process is used to reduce the thickness of a plate from 45mm down to 20mm. Roll diameter is 600mm and coefficient of friction between rolls and strip The specification is that the draft is to be equal on each pass. Determine a) Minimum number of passes required? b) Draft for each pass?

A two high rolling mill can further be classified as a reversing and a nonreversing mill. All rolling mills have common construction that is independent of the specific type of rolling required: 1. Backup rolls are intended to provide rigid support required by the working rolls to

Blooming mills are typically 2high reversing design with 30 to 50 diameter work rolls. Reversing roughing mills are a similar design and start with a cast or rolled billet and are used to reduce the cross sectional area of the workpiece prior to entering a finishing mill. The work rolls of roughing mills range from 16 to 36 in diameter.
The rolls can be ground to an hourglass shape. A 6high mill also allows for substantial roll shape, depending upon the horizontal movement of the rolls. Another advantage of a 6high mill is a larger work roll which can transmit considerable torque and allow for high speeds up to 7,000 FPM.
