发明名称 A PROCESS AND ROLL STAND FOR COLD ROLLING OF A METAL STRIP.
摘要 <p>A process is set forth for cold rolling of a metal strip, wherein the metal strip passes through a nip between two counter-rotating rolls, 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 two counter-rotating rolls forming a nip or rolling gap and nozzle means for blowing a cold and/or liquefied gas, preferably an inert gas, through at least 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.</p>
