A cooling tank for the thermal treatment of a rail head provided with a structure comprising a first volume (2), adapted to be filled with a cooling fluid; a second volume (4), arranged above the first volume and communicating therewith, so that the fluid passes from the first to the second volume and the rail head to be thermally treated can be immersed therein; a partition plate (5) between first and second volume, provided with a single row of holes (6), preferably arranged at the center of the width of the second volume, for generating jets of cooling fluid from the first to the second volume; a pair of longitudinal bulkheads (7), arranged in said second volume perpendicular to the plate and symmetrically with respect to the single row of holes, adapted to direct the jets of fluid exiting from the holes vertically upwards. |
