Two-Dimensional Roll Bite Model with Lubrication for Cold Strip Rolling
Advanced Materials Research, 2014To help optimize cold rolling operations, mixed lubrication models have been developed and embedded in roll bite models. The resulting models combine micro-fluidics in a porous medium (the lubricant flow between the contacting rough surfaces), microplasticity (roughness flattening / scratching), macro-plasticity (strip reduction) and roll thermo ...

Roll-bite deformation during the hot rolling of steel strip
Journal of Materials Processing Technology, 1992Abstract Heat transfer and deformation during the hot rolling of steel strip has been analysed with the aid of a coupled finite-element model based on the flow formulation approach. Sliding friction is assumed to prevail along the arc of contact and the effect of roll flattening on the roll radius has been incorporated. The model has been verified by

Behaviour of surface oxide scale before roll bite in hot rolling of steel
Materials Science and Technology, 2001AbstractHot stalling rolling tests using mild steel slabs with thin and thick scale layers, and cold stalling rolling simulation tests using lead slabs coated with brittle lacquer layers, have been conducted to investigate the behaviour of the surface oxide scales before hot rolling.

Local Variations of Strain and Strain Rate in Roll Bite Region During Rolling of Steels
Journal of Engineering Materials and Technology, Transactions of the ASME, 1998A combined experimental-numerical approach has been developed to quantify the strain rate variation of the workpiece in the roll bite region. In this approach, cold rolling experiments at a production mill were conducted first. Then tensile and microhardness tests were performed on workpieces before and after cold rolling to establish the relationship ...

A series of tests of cold rolling aluminum on a laboratory rolling mill showed that the amount of debris generated in the roll bile, increased with an increase in the amount of reduction. It also showed at light reductions, the debris generated distributed evenly between the surface of the sheet exiling the mill as smudge and the surface of the work ...

Neural tuner based adaptive control system development to improve roll bite process effectiveness
2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017A neural tuner is considered as a tool to adjust speed PI-controller parameters. It is proposed to use it in a rolling mill control system to reject disturbances caused by the roll bite process. Such disturbances amplitude varies according to rolling metal parameters change. The experiments to reject disturbances effectively are conducted with the help

The dynamic concentration theory describes a mechanism of how an oil reservoir forms at the inlet of the roll bite when an emulsion is used as the lubricant. This theory assumes that oil droplets larger than the thickness of the lubricant film in the deformation zone become trapped when they come into contact by both the surface of the sheet and the ...
