Process and device for de-scaling elongated metallic bars during continuous forming

A process for continuous de-scaling of elongated metallic material, particularly steel, said material having a plurality of successive areas disposed in a longitudinal direction to be de-scaled;

• said material being defined by a leading section, trailing sections and a section therebetween, said process comprising the steps of:
• continuously moving said material in one direction, and simultaneously shaping, particularly by rolling, said material;
• shaping said material leading section, and subsequently said section between said leading and trailing sections;
• heating said section between said leading and trailing sections and said trailing sections by the heat of a furnace during the shaping of said leading section;
• spraying a fluid, particularly a liquid, within a de-scaling zone on the material under high pressure in a predetermined cycle for a predetermined treatment time at a predetermined degree at each of the successive areas during material movement and prior to said material shaping;
• and
• displacing the de-scaling zone in the areas of the material in a direction opposite to the movement of the material at a relatively high velocity enabling material treatment time to be minimized in relation to a quantum of de-scaling.
