ABSTRACT:
A device and a process for continuous de-scaling of elongated metallic material, particularly steel. The material has front, center and end sections, and the process includes the steps of continuously moving the material in one direction, and shaping, particularly rolling the material, while the material center and end-sections are still subjected to the heat of a furnace, and the material has a plurality of successive areas in longitudinal direction to be de-scaled. The material is treated or de-scaled following the heating and prior to the forming thereof in predetermined cycles for a predetermined time at a predetermined degree at each of the successive areas, by spraying a fluid, particularly a liquid, on the material under high pressure. The de-scaling zone in the areas of the material is displaced in a direction opposite to the movement of the material at a relatively high velocity for the treatment time of the material to be as short as possible in relation to the degree of descaling to be accomplished.
