    May 30, 2013· 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 work piece. As per the rolls rotation direction, the mill can be either non-reversing (unidirectional) mill or reversing mill.

    Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll body and necks have to be considered as normal parts of designed components under high

  • Roll forming Wikipedia

    Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section.The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section (profile) is obtained.

  • Roll forming basics The Fabricator

    Tube and pipe mills use idlers between almost every pass to assist in forming the round. These idlers help form the strip, feed the steel into the next pass, and stabilize the section as it goes through the mill. Most roll forming does not require idlers but typically uses many more passes to make a tube.

  • Roll Modernizations Suction Rolls

    May 21, 2010· A suction roll is one of the most important process rolls and also one of the most costly rolls to maintain in a paper machine. By optimizing suction roll maintenance, a paper mill can reduce total maintenance costs, enhance roll reliability, lengthen service intervals and increase the total lifetime of the suction roll.

  • Rolling (metalworking) Wikipedia

    Roll forming, roll bending or plate rolling is a continuous bending operation in which a long strip of metal (typically coiled steel) is passed through consecutive sets of rolls, or stands, each performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll forming is ideal for producing parts with

  • Set up for roll forming success The Fabricator

    Sep 11, 2018· Once everything is set, you can run the material into the roll pass, then reset the rolls as needed. The roll gap on older roll formers typically is a little loose. Once the material is introduced to the rolls, the material naturally pushes the top rolls away from the bottom rolls, changing the roll gap.

  • Advanced roll forming troubleshooting The Fabricator

    The roll form tooling should be producing the desired cross section before the straightener is mounted. If the cross section is not to print, remove the straightener and adjust it before remounting. Roll form tooling that is set up properly will produce a symmetrically shaped part that does not twist.
