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.

A cooling roll comprising:
- an axle;
- and
- a sleeve having a length in an axial direction, and defining a radial direction and a circumferential direction and a diameter, the sleeve including:
- from an inside to an outside:
- an inner cylinder having a periphery and an inner cylinder length,
- a plurality of magnets on the periphery disposed along at least a portion of the inner cylinder length, each magnet being defined by a magnet width in the circumferential direction, a height in the radial direction and a length in the axial direction;
- a cooling system surrounding at least a portion of said plurality of magnets;
- the cooling system and the plurality of magnets being separated by a gap defined by a gap height in the radial direction, the gap height being a smallest distance between one of the plurality of magnets and the cooling system above,
- the magnet width of each of the magnets satisfying the following formula:
- gap height×1.1≤magnet width≤gap height×8.6.
