(EN) The present invention relates to a device for cooling a working roll (1, 2) belonging to a rolling stand used for rolling a long or flat product (3), characterized in that it comprises a cooling head in the form of a box section (6A, 6B) that is sealed except along a front face (42) lying a short distance from said roll (1, 2), and in which face a plurality of nozzles (41) has been machined or positioned in a determined pattern, said box section (6A, 6B) being concave and cylindrical at its front face (42). The box section (6A, 6B) is also fitted with transverse (5, 7) and lateral (8) plates which collaborate with the front face (42) of the box section so as to control the flow of cooling liquid and confine said liquid in the form of a highly turbulent flow. This then yields optimal cooling of the roll both in terms of the uniformity of the cooling across the surface thereof and in terms of the reduction in temperature as a result of the turbulent effect created.
Rolling stand for rolling a long or flat product comprising a work cylinder (1,2) and a device for cooling said work cylinder (1,2), characterised in that it comprises a cooling head in the form of a box that is more or less watertight in itself (6A,6B) except on its front (42), positioned a short distance from said cylinder (1,2) and in which several nozzles (41) have been machined or positioned according to a two-dimensional pattern, said box (6A,6B), equipped with a means for supplying a liquid coolant, being concave and cylindrical at a level of its front (42) with a radius such that, when the device is in the working position, a distance in the radial direction between said front (42) and the surface of the cylinder (1,2) increases starting from the end of the box (6A,6B) closest to the rollgap (9) and going away from the product being rolled.
