Abstract: A cooling roll including an axle and a sleeve, the sleeve having a length and a diameter and being structured as follows: an inner cylinder, a plurality of magnets disposed along at least a portion of the inner cylinder length, each magnet being defined by a width, a height and a length, a cooling system surrounding at least a portion of the plurality of magnets, the cooling system and the plurality of magnets being separated by a gap defined by a height, the gap height being the smallest distance between a magnet and the cooling system above, the magnets having a width such that the following formula is satisfied: gap height×1.1≤magnet width≤gap height×8.6.

Abstract: A process for cooling a metal substrate running in a longitudinal direction, said process including ejecting at least one first cooling fluid jet on a first surface of said substrate and at least one second cooling fluid jet on a second surface of said substrate, said first and second cooling fluid jets being ejected at a cooling fluid velocity higher than or equal to 5 m/s, so as to form on said first surface and on said second surface a first laminar cooling fluid flow and a second laminar flow respectively, said first and second laminar cooling fluid flows being tangential to the substrate, said first and second laminar cooling fluid flows extending over a first predetermined length and a second predetermined length of the substrate respectively, said first and second lengths being determined so that the substrate is cooled from a first temperature to a second temperature by nucleate boiling.
