The object of the programme is to develop a chemically and physically-based model of boundary lubrication during aluminium rolling, via a collaborative program between Engineering (CUED), Materials Science and Metallurgy (MSM) and the industrial partners Alcan and Esso. During rolling, the strip surface partially conforms to the roll roughness. Boundary lubrication at the areas of contact between the roll and strip determines friction and strip surface quality. The programme considers the large area of highly reactive metal surface created during rolling, how it reacts in the bite and how it is protected by lubricant additives. The work based at MSM uses an existing technique (the guillotined electrode), to measure the reaction kinetics for typical additive packages. Optical techniques will be used to investigate changes in surface structure. The work at CUED applies the reaction kinetics model to rolling. Measurements of the electrical conductance between roll and strip and surface examination of the strip will be used to determine how additives travel to and protect the new surface. A boundary lubrication model will be developed including this information, the reaction kinetics and a hydrodynamic model. This will be validated by measurements of friction during rolling.
