Chemistry of Rolling Lubricants | SpringerLink
For steel, emulsion formulations for cold rolling contain similar components to those used in hot rolling, namely, hydrocarbon oil together with esters, fatty acids, and E.P. materials for boundary lubrication, but these are now combined with selected emulsifiers. The esters can be animal- or vegetable-derived materials or synthetic products.Web
