U. Muhin et alii, Frattura ed Integrità Strutturale, 37 (2016) 318-324; DOI: 10.3221/IGF-ESIS.37.42 324 When reducing the effort antibend F1 or increasing efforts further work roll bending F2 tensile stress in the marginal areas of the rolled strip reduced - thus broadening of the band increases. Conversely, an increase in effort antibend F1 or reduction efforts F2 additional bending tensile stress in the marginal areas increased - thus broadening of the band decreases. C ONCLUSIONS athematical model of broadening rolled bands is developed and confirmed experimentally. The model allows to investigate the distribution of broadening along the source of plastic deformation, depending on the parameters of the strip rolling. It is shown that the tension decreases with the broadening of hot rolled sheet. It is shown that the hot-rolled sheet with a tension force of bending of the work rolls is effective.
