Abstract (en)
[origin: US7472574B2] A method of and a rolling mill stand for cold rolling of a metallic rolling stock (1), in particular rolling strip (1b) with nozzles for gaseous or liquid treatment media, with which the rolling stock (1) is displaced under a processing temperature through a roll gap (40) of a roll pair of upper working roll (2) and lower working roll (3) to undergo plastic deformation, and which permits in addition to a rolling stock surface improvement, the lubrication and surface protection of the rolling stock (1) and the rollers (2, 3) by a reduction in roll separating, with introduction of deep-chilled media, whereby deep chilled inert gas (41), ambient temperature inert gas (41a), lubricant emulsion (42), of admixed base oil, or oil-free, non-residue evaporating hydrocarbons are introduced against the sides (2a; 3a) of the working rollers (2, 3), and/or the rolling gap (40), and/or the rolling stock (1) in groups of jets from individual rows of nozzles (6a to 22b) for lubrication, cooling, and for inerting.
