Abstract

A process is set forth for cold rolling of a metal strip (18), wherein the metal strip passes through a nip (17) between two counter-rotating rolls (16 ), driven in counter-rotation substantially at room temperature wherein a cold and/or liquefied gas, preferably an inert gas, is blown into the area of the nip or roll gap. A roll stand according to the present invention comprises t wo counter-rotating rolls forming a nip or rolling gap and nozzle means (1) for blowing a cold and/or liquefied gas, preferably an inert gas, through at lea st one orifice of said nozzle means into the area of the roll nip. Preferably, the temperature of the cold and/or liquefied gas is appreciably lower than room temperature.
