The invention relates to a method for lubricating and cooling rollers () and metal strips () on rolling in particular, on cold rolling of metal strips (), wherein, on the inlet side () a minimal amount of pure lubricant () without a high water content is continuously supplied in an online controlled manner with a controlled viscosity and lubricity depending on a number of process data measurements () by means of a physical computer model () and the equivalent process data measurements () from the outlet side () are also used online by the physical computer model ().

Method for lubricating and cooling rollers and metal strips on rolling in particular on cold rolling of metal strips

A method of and a rolling mill stand for cold rolling of a metallic rolling stock (), in particular rolling strip () with nozzles for gaseous or liquid treatment media, with which the rolling stock () is displaced under a processing temperature through a roll gap () of a roll pair of upper working roll () and lower working roll () to undergo plastic deformation, and which permits in addition to a rolling stock surface improvement, the lubrication and surface protection of the rolling stock () and the rollers () by a reduction in roll separating, with introduction of deep-chilled media, whereby deep chilled inert gas (), ambient temperature inert gas (), lubricant emulsion (), of admixed base oil, or oil-free, non-residue evaporating hydrocarbons are introduced against the sides () of the working rollers (), and/or the rolling gap (), and/or the rolling stock () in groups of jets from individual rows of nozzles (to) for lubrication, cooling, and for inerting.
