A mixed film lubrication model for strip rolling and its correlation with experiment

Chapter


Abstract


  • A metal rolling model under mixed film lubrication is developed based on the Wilson and Chang's asperity flattening model. Both slipping and sticking friction at the solid contact area are assumed in the model. A second order Reynolds equation is used to calculate the hydrodynamic pressure in the fluid valleys. The hydrodynamic effect at inlet is also considered. The calculation results correlate reasonably well with the rolling pressure measurements from a sensing roll embedded with pin load cells and with film thickness measurements from the oil drop method. © 2000 Elsevier Science B.V.
