A suggested slip-line field for cold rolling with slipping friction

An experimental investigation on the deformation behavior during wire flat rolling process

“…An improper design can result in an undesirable lateral spread in wire leading to an unsatisfactory product. Although in the past some investigations have been carried out on the design of flat rolling of strips [4][5][6][7][8][9][10][11][12][13][14][15][16][17], there are few research works concentrating on the flat rolling of wires and this merits a further investigation on the process.…”

Slip Line Field Solution for Second Pass in Lubricated 4-High Reversing Cold Rolling Sheet Mill

“…A slip-line field solution for hot rolling was presented by Alexander [6]. Further slip-line field solutions for cold rolling with friction were suggested by Firbank and Lancaster [7] for small rolls only and a pass reduction of 20% and later slip-line fields for lubricated cold-rolling were proposed for 20 in Dia rolls with sheet reduction of 25% [8]. Work on slip-line field solutions for compression and rolling with slipping friction was also done by Collins [9].…”

Calculation of the rolling pressure distribution and force in wire flat rolling process

“…To design the process, it is important to estimate the magnitudes of involved parameters such as the rolling pressure distribution and rolling force. Although in the past, some investigations have been carried out on the calculation of rolling pressure and force in flat rolling of strip by the slab method, upper bound, slip line field, and finite element method [3][4][5][6][7][8][9][10][11], there are few research works concentrating on the wire flat rolling and this merits a further investigation on the process. Several parameters such as rolling reduction, friction coefficient, mechanical properties of wire, etc.…”
