ABSTRACT:
A cooling system for cooling a metal strip moving horizontally along a roller conveyor has a plurality of water boxes (4) arranged between the rollers (1,2,3) of the roller conveyor and each having upwardly directed outlet ducts (6) from which cooling water is projected onto the underside of the metal strip. The ducts (6) are parallel to each other and uniformly spaced across the width of the strip. To improve cooling, particularly its uniformity, the outlet ducts (6) are all shaped and oriented so as to project the cooling water with a component of motion opposite to the direction of movement of the metal strip, and each water box (4) is shaped and located relative to the next preceding roller (1,2,3) in the direction of movement of the metal strip so that during operation the water projected from each water box also cools said next preceding roller.
