- the INROWASP process makes it possible to obtain fine amorphous wires, very resistant to corrosion, having a tensile breaking load which can reach or even exceed 3200 MPa.
- the oxidation of the liquid jet is very rapid, the instant it leaves the die; this oxidation leads to significant wetting of the external part of the die by the oxide formed, causing disturbances at the level of the flow, and, consequently, to frequent ruptures of the jet and of the wire, and this even for a short distance between the die outlet and the coolant;
- Japanese patent application published under number 63-10044 describes a process in which an inert or slightly reducing protective gas is introduced into an envelope surrounding the pouring crucible.
- this protective envelope leads to a large bulk, which does not allow the casting orifice to be efficiently heated, and it is therefore not possible to avoid overheating of the orphisable alloy.
- the protective gas is not located at the level of the pouring orifice and the protection of the jet is then not satisfactory.
- Japanese patent application published under No. 1-271040 describes a process in which the heating of the amorphizable alloy in the upper part of the crucible is carried out using a first induction coil supplied with medium frequency current. , and the heating at the bottom of the crucible is provided by a second induction coil supplied with high frequency current.

- the arrows F7, F8 are located in the plane of FIG. 3 and they form the angle between them. al which is the angle of incidence of the jet 7 with respect to the circumferential direction of rotation of the liquid 9.
- the face upper 6A of the die 6 is planar and forms a crown, and the lower face 6B of the die 6 is also planar, being pierced with the orifice 60.
- the die 6 is arranged inside the conical part 2C of the crucible.
- a portion of the internal face of the part 2C, referenced 2OC, the lower end face 6B of the die 6 where the orifice 60 and the opening 21 are located define a chamber 22 into which opens a thin tube 23 passing through the bevelled face 2D.
- a neutral or reducing gas 24 is made to come through the tube 23.
- This gas 24 fills the chamber 22, being in contact with the face 6B and therefore the jet 7, at its outlet from the orifice 60.
- the gas 24 flows slowly out of the chamber 22 through the opening 21.
- the gas 24 can for example be nitrogen, argon, hydrogen, ammonia cracked, hydrogen or a mixture containing hydrogen being preferred, pure hydrogen being even more preferable.
- a seal 25 sandwiched between the die 6 and the crucible 2 seals between these two parts.
- the die 6 and the crucible 2 are made with different materials making it possible to meet the different requirements for the die 6 and the crucible 2.
- the material of the seal 25 is different from the materials used for the die 6 and the crucible 2.
- the coil 3 is formed by a single spiral winding around the axis yy 'of a thin copper tube 30, internally cooled by circulation of water, forming turns 30A which are inclined relative to the axis yy '( Figures 2 and 3) and which follow at a short distance the conical parts 2B, 2C and the cylinder 2A.
- turns 30A are shown in FIG. 3.
- the turn 30A lower, that is to say the one closest to the surface 80, is for example situated practically in a plane parallel to the surface portion 80 which faces it, this lower turn descending at the level of the orifice 60, following the yy 'axis.
- the chamber 22 is small compared to the crucible 2 and the die 6.
- the 2D beveled face of the lower part 2C makes it possible to have a low height for the chamber 22 and a small distance between the orifice 60 and the surface 80.
- the angle ⁇ 2D of this 2D beveled face is for example equal to twice the angle al or close to twice the angle ⁇ 7, for this purpose.
- the opening 21 preferably has a diameter of between 1 mm and 2 mm.
- the crucible 2 given its volume, must be made with a material whose cost is not high, and which makes it possible to withstand thermal shocks and strong thermal gradients, while being inert with respect to l liquid alloy.
- a material is for example vitreous silica, the crucible being produced in particular by hot drawing.
- the die 6 must be very inert vis-à-vis the liquid alloy, that is to say that it must resist mechanical erosion due to the liquid alloy, therefore to its. dissolution in this alloy, and that it must on the other hand resist reduction by the active elements of the liquid alloy.
- the material of the die can be, for example, a zirconia stabilized in cubic form, in particular a zirconia stabilized with at least one of the following compounds: oxide of 'yttrium, magnesia, lime, which guarantees a long period of use. It is also possible to produce the die by molding and sintering so as to ensure perfect reproducibility of its internal profile.

- the distance traveled by the jet 7 between the orifice 60 and the surface 80 of the liquid 9 may be small, preferably at most equal to 15 mm, and advantageously at more equal to 5 mm, this distance being at least equal to 2 mm, the presence of the protective gas 24, however, allowing more flexibility for adjusting this distance than if there were not this gas.
- This small distance avoids any start of resolution of the jet in drops and this while making it possible to work if desired with a relatively small value for the angle al, which often guarantees good continuity of the wire 12.
- the value of al is preferably between 40 ° and 90 °, this value being more preferably between 50 ° and 70 °.
- the location of the gas 24 in contact with the die 6, around the orifice 60 and the jet 7, makes it possible to effectively protect the face 6B of the die 6 against wetting by the oxide which would form on the jet 7 in l absence of this protection, and therefore to increase its lifetime, while avoiding the oxidation of the alloy 4 of the jet 7, and this with a very low gas flow rate 24.
- this flow rate is between 0 , 5 cm / s and 5 cm / s.
- the alloy 4 corresponds to the formula Fe Cr Si B leverageNi Co ⁇ Mo, this alloy being devoid of other elements, if ⁇ C, 7 / it is unavoidable impurities.
- a, ⁇ , ⁇ , ⁇ , ⁇ , ⁇ , ⁇ , ⁇ are the atomic percentages of the elements to which they relate, these percentages checking the following relationships:
- This alloy therefore has a very high iron content since it is greater than 60% (atomic%).
- These alloys are economical, and the invention makes it possible to use them to produce large lengths of amorphous wires, without breakage, these wires having advantageous mechanical properties, while known methods did not allow them to be used because they led to breakages. frequent and to wires with poor mechanical properties.

- the part of the die 42 which is located under the part 41B of the crucible 41 is surrounded by a ring 44 pierced with a hole 45 into which the tube 43 opens, where the gas 24 arrives in the ring 44.
- This ring 44 has by example externally the shape of a cylinder portion whose upper end 46 is fixed in sealed manner to the bevelled face 41C by surrounding the orifice 420, while its lower end 47 is practically parallel to the surface portion 80 which faces, and a short distance from that portion.

On the other hand, means (3) are used to heat the alloy (4) both in the crucible (2) and in the die (6) and an inert or reducing gas is brought directly into contact with the jet. (7) at the outlet of the die (6).
