The rolling mill is a machine designed to produce thinner gauges of sheet metal and wire. The rolling mill is used for reducing the thickness of sheet metal. The rolls for wire are cut with 'v' shaped grooves arranged in decreasing sizes, allowing for gradual reduction of wire diameter and producing a square cross section of wire.
In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metal rolling manufacture is set up is called a rolling mill. Rolling mills often vary in the type, number, and position of rolls.

INSTRUCTIONS / MAINTENANCE FOR HAND OPERATED ROLLING MILLS • The bearings are self-lubricating and need no maintenance. • The drive gears at left hand end (behind guard A) should be greased every 6 months. Remove the circlips and extension rollers and then the two screws for the cover for access to the 2 gears. Use standard gear grease.
Rolls are relatively large tools with an extended life but ultimately they are only tools. A summary of materials in use for the production of rolls is presented in table 1. K. H. Schröder: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS File: SCHROEDER_ROLLS_010703.DOC.
In order to analyze the influence of technical parameters on work roll axial force of four-high continuous variable crown (CVC) mill, the deformation analyzing model with top roll system and strip was established based on influence function method. Then a CVC work roll curve designing scheme was proposed and it was carried out on some cold rolling mill considering the …
way it behaves during rolling or shearing. To eliminate further any possibility of a mix-up, additional laboratory spot tests are made from scrap material cropped from the billets as they go through the rolling mill.
