Roll Pass Design – IspatGuru

Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the minimum element

Analysis of roll stack deflection in a hot strip mill

The working roll diameter is 500 mm. Determine the rolling load on the rolling stand if the co-efficient of friction is 0.07. Also determine the rolling torque. Solution: Example 2: A billet of area of section 150 mm x 150 mm is rolled to 120 height in a rolling mill with 600 mm roll …

Torque and power requirement for roller | Physics Forums

Roller bearingshave a higher load carrying capacitythan ballbearings. Therefore, roller bearings, i.e. cylindricalroller bearings, tapered roller bearingsor sphericalroller bearings, become the automatic choice for carrying the radialloads. These bearingsare made of through-hardened rolling bearing steelor in some casesof casehardening steel.

THE MECHANICS OF TENSION CONTROL

The upper roller of 4 rolls bending machine is driven roller. The total drive torque acting on the upper roller is adding up the torque consumed on the deformation and overcome the friction. Friction torque including frictional resistance consumption to overcome shaft roller rolling on bending plate and torque consumption in the roller bearing ...

A BASIC UNDERSTANDING OF THE MECHANICS OF …

Torque required to provide a certain level of tension to a web is total tension measured across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size, through a machine run, to keep tension constant. Conversely, the torque driving the

Operation of Rolling Mills - Schweitzer Rolling Technology

Sep 11, 2007· But in reality, mill rolls deflect under load, creating more pressure and elongation at the edge of the strip and producing a shape defect known as edge wave. To counteract mill roll deflection, steelmakers grind the rolls with a "crown," making the middle of the roll larger in diameter than the edges.
