Analysis of the bending of an aluminum strip with a high deformation focus using computer modeling

Hot rolling simulation model was built considering the inf luence of such factors as: the difference in coefficient of friction on the upper and lower work rolls, different angle of slab entry into the deformation zone, and the amount of strip bending strain in the vertical plane. The numerical experiment was carried out by finite element simulation in the DEFORM 2D software package. The degree of inf luence of the above factors and their impact patterns on the rolling process were determined. It was shown that the strip slope value affects the asymmetry more than the difference in friction conditions on the lower and upper rolls. In addition, it was found that the amount of bending can be significantly reduced by increasing the amount of strain. This is due to the fact that a higher amount of strain gives less asymmetry in the rolling zone.
