Backup rolls for Cold-rolling Mills of 90ХФ, 75ХМФ, 75Х2МФ steel grades – 50 mm; 75Х3МФА – 55 mm; 45Х5МФ, EBR 42 – 100 mm on radius. Hardness variation along the roll barrel length is within 2-3 HSD.
Backup Roll Chock Liners- Backup roll outside chock liners protect the chock from wear and allow close clearances between the mill housing and backup roll chocks. This helps to maintain roll alignment and gaps, which both contribute to the ability of the mill to roll strip to a precise shape and gauge.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes . There are many different types of mills and many types of materials processed in them.
Materials Used In Roll Forming Roll forming is a process in which a strip or sheet of metal, such as steel, is passed through a continual set of stands (rolls), until a desired cross-section profile is achieved.
Plate roll manufacturers commonly rate their machines according to baseline material yield strengths of 36,000 to 38,000 pounds per square inch (PSI). However, you need to realize that steel mills are producing materials with ever-increasing yields.
The WHEMCO companies in Pennsylvania and Ohio, USA manufacture a full range of mill rolls – spun cast iron, cast steel and forged steel. Each of our roll manufacturing facilities has the expertise, equipment and experience to …
Rolling of Metals • Rolling –reducing the thickness or changing the cross-section of a long workpiece by compressive forces applied through a set of rolls • Developed in late 1500s • Accounts for 90% of all metals produced by metal ... may actually occur if edger mills are not used

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 can be used.
Urethane Rolls are 2-roll bending machines, unlike traditional plate bending rolls that use a 3-roll or 4-roll design. Urethane rolls accurately bend plate and sheet metal into arcs in one pass. One pass bending results in increased productivity. Urethane rolls are designed to bend without marring or scratching the surface of the material.
Wet grinding ball mill in mining operation. Balls within mill retain their high grinding efficiency regardless of wear. Ball mills are used extensively for grinding metal bearing ores and abrasive minerals.

FENN Rolling mill machines are available in both 2Hi and 4Hi roll configurations, and mills may be either work roll driven, back-up roll driven, or a combination of both. On the small end of the spectrum, 4Hi rolling mills with work rolls are offered as small as .500" (12.7mm) in diameter.
During a metal rolling operation, the geometric shape of the work is changed but its volume remains essentially the same. The roll zone is the area over which the rolls act on the material, it is here that plastic deformation of the work occurs.
Calculate draft space and roll speed for each mill stand to plan rolling sequences and specified dimensions and tempers. Calculate specific material, equipment, or labor requirements for production. Start operation of rolling and milling machines to flatten, temper, form, and reduce sheet metal sections and to produce steel strips.
Roll crusher mainly crushes materials by the mutual extrusion between two Applied Materials: River gravel, iron ore, limestone, quartz, granite and other Send Inquiry Toothed roll crusher has two relatively rotating rollers with sharp teeth on them.

to roll beams as large as 44”, form plates on a 1,000-ton, 40’ press brake, and roll plate as thick as 6” x 14’. Clayton also has a full-line machine shop, with large CNC lathes and mills.
Roll Crusher Applications. Roll Crushers are simple in design and construction, long-lasting, economical, and versatile. Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or cone crusher.
Crushing rolls might, logically, include roll crushers of the sledging type, the name, by popular usage, is restricted to the double-roll machine (with either smooth or corrugated shells) which crushes entirely by pressure between the surfaces of the roll faces.
Four-high mills: Four-high mills are used for rolling flat material such as sheet and plate. This type of mill uses large backup rolls to reinforce smaller work rolls, thus obtaining fairly large reductions without excessive amounts of roll deflection.
• Work rolls, intermediate rolls, backup rolls, Sendzimir rolls for various cold rolling strip mills and hot rolling strip mills, applicable to rolling of carbon steel, stainless steel and non-ferrous metal of copper and aluminum.
of the rolls and roll-pack was developed using the commercial code LS-DYNA. The first step in any FEM process is to ascertain accurate mechanical properties of the materials.
