ABSTRACT:
Apparatus for cooling a work roll in a rolling mill for rolling metal strip, has a plurality of sprays arranged in closely spaced rows extending in the longitudinal direction of the work roll, the sprays spraying water onto the work roll surface in a manner such that the surface of contact of the cooling water of each spray on the work roll surface is oblong in shape and the longitudinal axes of the said surfaces of contact form an angle to a describing line of the work roll surface. At least some of the sprays in at least two consecutive rows in the peripheral direction of the work roll are arranged so that the longitudinal axes of the surfaces of contact of the sprays in a first such row form an acute angle .alpha. to a first describing line on the work roll surface, and the longitudinal axes of the contact surfaces of the sprays in the second such row form an obtuse angle .beta. to a second describing line, whereby the surfaces of contact form a herringbone pattern. This improves cooling, particularly removal of cooling water from the roll.
