Definitions

  • the present invention relates to a method and to a device for producing at least one narrow metal strip as well as to a metal strip produced by this process.
  • the invention also relates to a nozzle used for the preparation of this metal strip.
  • strip is intended to mean a body of elongated shape and whose transverse dimensions are much less than its length.
  • the wires, the sheets as well as the metallic ribbons are for example considered as metallic bands.
  • oxidizing agent such as for example metallic supports for catalysts.
  • Such orifices are regularly disposed at the lower end of the nozzle in a direction transverse to the direction of movement of the surface of the cooling member and are facing downward facing said cooling surface.
  • the cooling member is formed for example by a wheel.
  • This technique makes it possible to form metal strips of small width between 0.5 and 1.5 mm on the cooling surface, the thickness of which is limited to certain values which depend on the widths of these strips.
  • an orifice with a diameter equal to 1 mm makes it possible, for example, to form on the cooling surface a metal strip with a width equal to 1 mm and whose thickness cannot exceed 30 ⁇ m which is unacceptable for applications where a minimum thickness of 40 ⁇ m is required.
  • the Applicant has logically considered increasing the diameter of the circular orifices of the nozzle so that the thickness of the metal strips is greater.
  • the Applicant has envisaged reducing the speed of movement of the cooling member in order to increase the thickness of the metal strip formed.
  • the object of the invention is to remedy these drawbacks by proposing a method and a device for producing at least one metal strip of small width and having a thickness greater than that of the metal strips obtained by the technique of previously cited prior art.
  • the invention also relates to a nozzle for the preparation of at least one narrow metal strip formed of a vertical body in which is formed an internal channel for the passage of a molten material and comprising at one of its so-called lower ends a plate provided with at least one orifice for ejecting the molten material onto a mobile cooling surface, characterized in that said orifice has an elongated shape in the direction of movement of said cooling surface and which is contained in a substantially horizontal plane.
  • the invention also relates to a metal strip of small width obtained by the process mentioned above, characterized in that said metal strip has a width less than or equal to 2mm.
  • the metal strip has a thickness greater than or equal to 30 ⁇ m.
  • the device designated as a whole by the reference 1 is intended in the preparation of at least one metal strip 2 of small width and comprises a metallurgical container 3, called a distributor, containing a molten material 4.
  • the metallurgical container 3 has for example a general shape flared upwards 3a and its cross section is rectangular.
  • the molten material 4 contained in the metallurgical container 3 is maintained at a temperature above its melting temperature by means for example of a conventional induction coil and not shown, arranged around said container 3 and over its entire height.
  • the molten material is formed for example by a metal alloy of the following weight composition: chromium from 15 to 25%, aluminum from 4 to 10%, the rest being made up of iron and possibly rare earths or elements assimilated to rare earths.
  • the metallurgical container 3 comprises in its constricted lower part 3b, a nozzle 10 communicating with said container 3 and integral with the latter by conventional means not shown.
  • the nozzle 10 is for example provided on its upper external face with a thread corresponding to a thread located on the inner wall of a conduit arranged in the bottom of the container 3, thus allowing its fixing by screwing.
  • the nozzle 10 is formed of a vertical body 11 in which is formed an internal channel 12 communicating with the metallurgical container 3 and allowing the flow of molten metal 4 towards one of the ends 10a called the bottom of the nozzle 10 .
  • the vertical body 11 is provided at its lower part with a horizontal plate 11a perpendicular to the side walls of the vertical body 11 and comprising at least one orifice 13.
  • the device 1 also comprises at least one movable cooling surface 20 situated under the nozzle 10 and facing the orifice 13.
  • This cooling surface 20, formed for example by the surface of a wheel 21, is provided with at least one groove 22 disposed opposite the orifice 13 and in alignment with the latter.
  • the orifice 13 has an elongated shape in the direction of movement of the cooling surface 20 and which is contained in a substantially horizontal plane.
  • the orifice 13 has the function of allowing the ejection of the molten material 4 in the direction of the cooling surface 20, and its shape favors the ejection of said molten material in the groove 22 placed opposite said orifice 13 in which it solidifies by forming the metal strip 2.
  • this molten material is subjected to a sufficiently high pressure by placing the metallurgical container 3 in communication with atmospheric pressure and by having a sufficient height of molten material in said metallurgical container 3.
  • the plate 11a of the vertical body 11 is provided with four identical orifices 13 which are parallel to one another and regularly spaced a distance substantially greater than the greatest width of each orifice 13 and for example equal to 1.5 times the greatest width of the orifice.
  • the cooling surface 20 of the wheel 21 has four grooves 22 each arranged opposite an orifice 13 of the nozzle 10 and parallel to each other.
  • the respective dimensions of the grooves 22 and the orifices 13 are judiciously chosen to obtain metal strips 2 of a given width and whose thickness is reinforced compared to that of metal strips obtained in a conventional manner by the casting of molten metal onto a cooling surface through orifices of circular shape.
  • the Applicant has also found that the use of a nozzle with elongated orifices for ejecting molten material onto a smooth cooling surface is not satisfactory since the width of the strips thus formed is further increased than their thickness.
  • each groove 22 in its upper part 22a is greater than the greatest width of each orifice 13.
  • each groove 22 in its upper part 22a is between 1.5 and 5 times the largest width of each orifice 13 and is for example equal to 1.75 times the largest width of each orifice.
  • each groove 22 can be given an adapted shape.
  • each groove 22 is between one and twenty times the thickness of the strip 2, preferably between one and ten times this thickness and more preferably between one and five times the thickness of the metal strip 2.
  • each groove 22 is 4.5 times the target thickness of the metal strip.
  • each groove 22 has a trapezoidal transverse profile, but this shape is in no way limiting and, transverse profiles in the form of a V or semi-circular can be envisaged.
  • Each orifice 13 is located at a distance from the cooling surface 20 of between 0.1 and 2mm, preferably between 0.1 and 1mm and for example equal to 0.5mm.
  • each orifice 13 has an oblong shape, but can also take various elongated shapes depending on the geometry desired for the metal strips 2.
  • each orifice 13 is less than 6mm, preferably less than 3mm and for example equal to 2.8mm.
  • the linear speed of movement of the cooling surface 20 is between 10 and 60 m / s and preferably between 30 and 45 m / s.
  • the metal strips 2 produced by the method according to the invention have a width less than or equal to 2 mm and a thickness greater than or equal to 30 ⁇ m.
  • metal strips with a width of 1.2mm and a thickness of 45 ⁇ m are produced using a nozzle with an oblong orifice 2.8mm long and 0.8mm wide for a linear speed of movement of the cooling surface 20 to 40 m / s.
  • an orifice nozzle circular with a diameter of 1.1mm would have made it possible to obtain a metal strip 1.2mm wide and 30 ⁇ m thick.
