Aluminium Hot and Cold Rolling | SpringerLink
Its viscosity under roll bite conditions determines the amount of rolling oil entrapped into the roll bite. Thus, the viscosity and the viscosity-pressure-temperature relationships are decisive features of the base oil. Typical hydrocarbon base oils used for high-speed cold rolling mills show kinematic viscosities of 1.5–3 mm 2 /s (40 °C).
