Definitions

  • the present invention relates to a method for cooling a metallic product in movement and in particular in movement.
  • one of the most widely used means of ensuring this cooling consists in directing, onto the passing product, jets of an appropriate cooling agent, such as air, water, steam or water, singly, in a mixture or sprayed together, by means of suitable devices.
  • an appropriate cooling agent such as air, water, steam or water
  • this device has certain drawbacks which increase with the width of the product to be cooled.
  • the present invention relates to a method making it possible to remedy these drawbacks.
  • the process which is the subject of the present invention for cooling, by means of an aqueous liquid continuously discharged, a metallic product in movement, is characterized in that a space of constant thickness is formed by providing a wall provided with at least one orifice opposite the part of the product to be cooled, the two surfaces, that of the part of the product to be cooled and that of the wall provided with the orifice, being substantially parallel, in that the 'said space is completely filled by means of said aforementioned aqueous liquid, this liquid being introduced into said space through the orifice (s) formed in said wall, and in that by means of the aqueous liquid itself thus supplied , an agitation of the aqueous liquid filling the said space is created.
  • the specific flow rate of the aqueous liquid is between 5 l / m 2. s and 80 1 / m 2. s, and the distance between the surface to be cooled and said wall is between 5 mm and 300 mm.
  • the aforementioned specific flow and distance are chosen according to the intensity of the cooling to be applied to the metal product.
  • the method of the invention thus makes it possible to modify the intensity of the cooling applied as a function of the type of product to be obtained. It is in particular possible by this process to produce coolings leading both to mild steel products and to quenched and self-annealing products, possibly treated only in a surface layer.
  • a quenching and a self-tempering will be obtained by introducing the beam at the temperature of 850 ° C and at the speed of 0.7 m / s in the cooling installation providing a specific flow rate of 20 1 / m 2 .s and the distance between the faces of the product and the cooling system is 10 mm; the outlet temperature is 575 ° C.
