Strip rolling processes are conducted in the mixed lubrication regime, so that boundary additives are an essential feature of the rolling oil. Fatty alcohols are by far the preferred additives: why are they dominant, and what makes them so good for this particular application? A series of model lubricants have been formulated and tested first with the Plane-Strain Compression Test (PSCT) from RT to 200°C. Then some of the formulations have been studied on a high-speed experimental rolling mill. Conclusions from PSCT and rolling tests converge on several points. Fatty alcohols indeed outperform all other formulations; combining them with other molecules may degrade their action.
