Abstract |
Our paper shows the theoretical and experimental investigations of copper plates' dressing and rolling parameters. The dressing-rolling process was carried out on the experimental unit by the plate bending between two idle rollers oppositely to the initial curvature with simultaneous assymetrical deformation of plate along its thickness between the rollers in two-roll chamber between idle rollers. The plate's bottom face (thickness h = 5 mm, width B = 80 mm, elasticity model Ecopper = 1.1·105 MPa) was lubricated during the dressing and rolling of copper plate for assymetrical deformation of plate with the dished initial curvature. Using the technical oil SP-3 (СП-3) (friction coefficient f = 0.06–0.08), the reduction in thickness of this lubrication was decreased by 15.5 % in comparison with its value for the plate's upper face. We give the technological parameters of the experimental unit for dressing and rolling of copper plates. The experiments showed that copper efficiency during the copper plate dressing is 60–85%. |
