Patent ID: 7472574

Claim:
A method of cold rolling of a metallic rolling stock ( 1 ), in particular of a rolling strip ( 1 b ), wherein: the rolling stock ( 1 ) is displaced under a processing temperature through a roll gap ( 40 ) of a working roll pair ( 2 , 3 ) to undergo a plastic deformation; and in a wedge region ( 18 , 19 ) of the rolls-strip exit side, a deep chilled inert gas is applied to the surface of the rolling stock and is fed in the roll gap in form of jet groups for inerting and cooling; characterized in that an inert gas is applied, alternatively or in addition to the surface of the rolling stock in a region of the strip exit ( 21 , 22 ); the strip exit side inert gas also provides for cleaning of the surface of the rolling stock; a separate medium for lubrication in form of a jet group is applied to the surface of the rolling stock and/or fed in the roll gap in a region of the strip entry ( 7 , 8 ) and/or roll gap entry side ( 11 , 9 ), and is applied in a minimum amount with a layer thickness corresponding to surface roughness of the surface of the rolling stock.
