ABSTRACT

Cold rolling manufacturing process, a major issue is roll elastic deformation and its impact on roll load, torque and interaction stresses. As in many systems implying mechanical contact under high loading, a central part is under “sticking friction” (no slip) whereas both extremities do slip to accommodate the material acceleration of the rolled metal sheet. During the cold reduction of steel sheet in a rolling mill, rolling oils are used for lubrication to offer the desired steel surface. Rolling oil formulations consist largely of mineral oils, glycerides and/or synthetic esters, fatty acids, emulsifiers and extracts. These oils are generally used as 3-7% emulsions and will be subjected to high temperature and pressure during use.Evidence was found that the bio composite oils degraded on heating and the spectroscopic investigation indicated that this was due to rearrangement of unsaturated components configuration. In this work bio-based composite oil was compared with synthetic oil and optimize for preeminent performance on rolling operation.
