Definitions

  • the invention relates to wires of amorphous metal alloys and in particular the methods and devices making it possible to obtain wires of amorphous metal alloys by rapid cooling in a liquid medium, these alloys being in particular based on iron.
  • the projected jet tends to resolve in drops, which causes either a discontinuity of the jet leading to the impossibility of having a continuous wire, or to the formation of a continuous wire whose section is irregular.
  • the object of the invention is to remedy these drawbacks.
  • the invention also relates to the amorphous yarns obtained with the method or the device according to the invention.
  • These wires can be used, for example, to reinforce plastic or rubber articles, in particular tire casings, and the invention also relates to these articles.
  • FIGS 1 and 2 show a known device for making amorphous metal wires.
  • This device 1 comprises a reservoir 2 constituted by a crucible around which is located the induction coil 3 which makes it possible to melt the amorphizable metallic alloy 4 based on iron placed in the reservoir 2.
  • a gas under pressure 5, for example of argon allows the liquid alloy 4 to flow through the nozzle 6 so as to obtain a jet 7, this gas 5 being inert with respect to the alloy 4.
  • This jet 7 reaches the layer 8 coolant 9 pressed against the internal wall 10 of a drum 11, this liquid 9 being for example water.
  • the jet 7 then solidifies very quickly to give the amorphous metallic wire 12.
  • FIG. 1 is a section made perpendicular to the axis xx ′ and FIG. 2 is a section made in a plane passing through the axis xx ′, this plane being referenced by the straight line segments II-II in Figure 1.
  • the jet 7 tends to resolve in drops before entering the layer 8. To avoid this resolution in drops, it is necessary to comply with the following operating conditions. - The distance between the nozzle 6 and the layer 8, that is to say the length of the jet 7, must be short, less than about 3 mm; - The jet ejection speed 7 must be high, at least equal to around 8 m / s, that is to say that the gas pressure 5 must be high, at least equal to 3.5 bars; - The temperature difference between the molten metal 4 and the air surrounding the tank 2 is very high, and, due to the short distance between the nozzle 6 and the water 9, it is not possible to use parts making it possible to isolate and reinforce the nozzle 6 and the reservoir 2.
  • the argon pressure 5 is therefore less than approximately 5 bars
  • the speed of the jet 7 is less than 10 m / second, which can lead to a lack of regularity of the jet 7 and to a low manufacturing speed of the wire 12;
  • the production of the wire 12 therefore requires a very narrow compromise of operating characteristics; this compromise is very difficult to respect in industrial manufacturing and it is not always possible to find it;
  • the tank 2 must be located inside the drum 11 and its capacity is reduced, at most equal to about 500 g, the length of the wire 12 is therefore necessarily limited;
  • FIGS 3 and 4 show a device 20 according to the invention.
  • the device 20 comprises the rotary drum 11 with an axis of rotation xx ′, and the casting installation 21 which makes it possible to project a jet 7 of molten metal into the layer 8 pressed by centrifugal force against the internal wall 10 of the drum 11.
  • FIG. 3 is a side view and Figure 4 is a section taken along a plane passing through the axis of rotation xx ′ and through the point of contact 0 of the jet 7 with the layer 8, this section being shown diagrammatically by the segments in a straight line IV-IV in FIG. 3.
  • a part of the installation 21 is shown in detail in FIG. 5, this FIG. 5 being a section made along a plane passing through the axis yy ′ of the installation 21, the section of FIG. 5 being shown diagrammatically by the straight line segments VV in FIG. 4.
  • the installation 21 is arranged outside the drum 11.
  • This installation 21 comprises a reservoir 22 constituted by a ceramic crucible, for example made of zircon or alumina.
  • the crucible 22 rests on the insulating spacer 23 made for example of aluminous refractory concrete.
  • Around the crucible 22 is arranged a cylindrical jacket 24 made for example of zircon.
  • a stuffing 25 in the form of compacted powder of alumina.
  • the jacket 24 is surrounded by the induction coil 26 capable of melting the amorphizable alloy 4 based on iron by passage of electric current.
  • the assembly of the crucible 22, the spacer 23, the jacket 24 and the packing 25 is surrounded by an enclosure 27 comprising two walls 28, 29, made of steel, a coolant 30, for example water, being disposed between these walls 28, 29.
  • a part 31, in the form of an inverted cup, is disposed in the opening 32 passing through the bottom 33 of the crucible 22 and the bottom 34 of the enclosure 27.
  • the spacer 23 and the jacket 24 rest directly on the bottom 34 of the enclosure 27.
  • the cup 31 is made for example of zircon.
  • the top 35 of the cup 31 is crossed by a nozzle 36, made for example of zirconia or alumina, the part 31 therefore serving as a support for the nozzle 36.
  • the opening 37 of this nozzle 36 is disposed along the axis yy ′ which is the axis of the opening 32 and the axis of the installation 21.
  • the installation 21 also comprises a device 38 comprising the flange 39 which makes it possible to apply this device against the enclosure 27.
  • the device 38 also comprises the cylindrical enclosure 40, and the annular rim 41 on which is applied a part 42 in the form of an inverted cup, the top 43 of which has an opening 44 situated under the opening 37 of the nozzle 36 and having the axis yy ′.
  • the flange 39, the cylinder 40 and the flange 41 are made for example of steel and the part 42 is made of ceramic, for example of zircon.
  • the internal volume 45 of the cylinder 40, under the rim 41, and the internal volume 46 of the cup 42 communicate with each other through the opening 47 and together constitute the enclosure 48.
  • the seal at the flange 39 is ensured by an O-ring 49, for example made of rubber.
  • the operation of the device 20 is as follows:
  • the passage of electric current through the induction coil 26 allows the amorphizable alloy 4 placed in the crucible 22 to be melted.
  • This molten alloy 4 allows the upper part of a steel ferrule 50 previously disposed around the support to be melted 31 between this support 31 on the one hand and the crucible 22, the enclosure 27 and the spacer 23 on the other hand.
  • This partial melting of the ferrule 50 forms the steel seal 51 between the support 31 and the crucible 22.
  • This seal 51 combined with the O-ring 49 ensures good sealing of the installation 21.
  • the argon 5 under pressure, placed in the crucible 22 above the alloy 4 allows the extrusion of this alloy, through the nozzle 36, in the form of a jet 7 which passes through the opening 44 of the part 42 along the axis yy ′ and crosses the interior volumes 46 and 45, that is to say the enclosure 48 to finally leave the installation 21 and reach the layer 8 of water 9 where it solidifies very quickly to give the wire 12.
  • the speed quenching is, in known manner, of the order of 105 ° C / second, the water 9 being cooled by a known refrigeration system arranged around the drum 11, this system not being shown in the drawing for the purpose of simplification.
  • a small amount of hydrogen 52 is made to arrive through the opening 53 made in the cylinder 40 above the rim 41.
  • the hydrogen 52 thus fills the space 54 which is outside the cup 42 between it ci and the support 31, the cylinder 40 and the rim 41.
  • the hydrogen 52 is thus thus in contact with the nozzle 36.
  • a gas 55 capable of reacting chemically with at least one of the constituents of the alloy 4 is made to arrive, this gas 55 being for example a mixture of hydrogen and water vapor, through the opening 56 made in the cylinder 40 below the rim 41.
  • This mixture 55 thus fills the interior volumes 45, 46, that is to say the enclosure 48.
  • the hydrogen 52 leaves through the opening 44 in the enclosure 48.
  • the hydrogen is burned at the outlet of the cylinder 40, as it passes through the ambient air, for safety reasons, so that, during the operation of the device 20, a stream of hydrogen 52 is maintained through the opening 53, and a stream of mixture 55 of hydrogen and water vapor through the opening 56.
  • the gas mixture 55 is capable, in contact with the jet 7 which is at high temperature, of oxidizing at least one element of the alloy 4 , especially silicon. This reaction takes place superficially and forms a very fine surface layer which makes it possible to stabilize the jet 7, this jet remaining liquid in its mass.
  • the presence of hydrogen 52 in contact with the nozzle 36 makes it possible to protect the latter against any action of the mixture 55.
  • the phenomenon making it possible to stabilize the jet 7 is complex, it is probably due to the fact that the surface oxidation results in a decrease in surface tension and an increase in surface viscosity, as a result of a submicroscopic oxidized surface layer, of thickness less than 0.1 ⁇ m.
  • the length L of the jet 7, between the nozzle 36 and the layer 8, can easily exceed 1 cm, this length L preferably being between 10 cm and 1 m.
  • the spacer 23, the jacket 24 and the packing 25 allow good thermal insulation of the crucible 22.
  • the support 31 can have a length parallel to the large axis yy ′, which avoids excessive thermal stresses for this support 31, and the presence of this elongated support 31 and of the cup 42 makes it possible to isolate well thermally the nozzle 36.
  • the steel enclosure 27 makes it possible to have good mechanical resistance of the assembly, the presence of all these parts being possible thanks to the large length L.
  • This improvement in the thermal and mechanical resistances of the installation 21 makes it possible to increase the pressure of the gas 5, which can exceed 5 bars, the speed of the jet 7 therefore being able to exceed 10 m / s.
  • the installation 21, and therefore the crucible 22 are arranged outside the drum 11, it is therefore possible to use a crucible 22 of large volume, and therefore to use a large quantity of alloy 4, much greater 500 g, so that the length of wire 12 can be important.
  • the distance L between the nozzle 36 and the layer 8 can vary within wide limits, which provides great flexibility in the settings of the installation 21 relative to the drum 11, in particular as regards the direction of the jet 7 by relative to the surface 80, arranged towards the axis xx ′, of the layer 8.
  • the stabilization of the jet 7 makes it possible to use, if desired, low gas pressures 5, for example less than 3.5 bars, and therefore low jet speeds 7, for example less than 8 m / s, which further favors the flexibility of the settings of the device 20 as a result of the flexibility in the choice of pressures.
  • a low jet speed 7 is for example necessary in the case where the kinetics of the oxidation reaction is slow, the invention allowing, even in this case, good continuity of the jet 7.
  • the device 20 makes it possible to extend the range of alloy composition with which it is possible to obtain an amorphous wire 12.
  • the known devices for example the device 1, do not make it possible to obtain amorphous wires from alloys containing iron, silicon, boron, or iron, nickel, silicon and boron if the silicon content is less than 5% (atomic%), because we do not obtain only marbles.
  • the invention makes it possible to obtain amorphous wires from such alloys, even if the silicon content is less than 5% (atomic%) thanks to the oxidizing gas 55.
  • the jet 7 can be very quickly quenched in the layer 8 so as to obtain an amorphous wire 12, it is essential that the jet 7 remains liquid throughout the entire length L, that is to say that the jet 7 must be at a temperature higher than the melting temperature of the alloy 4 during the impact of the jet 7 with water 9.
  • the hydrogen 52 and the oxidizing gas mixture 55 must therefore not significantly cool the jet 7, the solidification being carried out only within the layer 8.
  • the silicon content in the alloy 4 should preferably be higher at 0.2% (atomic%).
  • the jet 7 flows for example from top to bottom, as in the device 20 described above, in a vertical direction, and the axis xx′ of the drum 11, and therefore the generatrices of the water cylinder 80 limiting the layer 8 in the direction of the axis xx ′, make an angle of 40 to 70 ° with the vertical.
  • the characteristics of the device 20 are as follows: - drum diameter 11: 47 cm; - angle of the axis xx ′ with respect to the vertical: 45 °; - linear speed of rotation of the surface 80: of the same order of magnitude as that of the jet 7; - thickness of the water layer 8: 0.5 to 3 cm; - crucible 22 with a capacity of 3 kg of amorphizable alloy 4; - diameter of the opening 37 of the nozzle 36: 165 ⁇ m; - water temperature 9: 5 ° C;
  • This device 20 is used to carry out the following two tests:
  • the jet 7 is continuous throughout its journey from the nozzle 36 to the layer 8, without the formation of drops.
  • This combined with the very rapid cooling achieved thanks to the layer 8, makes it possible to obtain an amorphous wire 12 whose circular section of diameter 160 ⁇ m has a regular shape over its length.
  • the crucible 22 has been shown as a tank in which the alloy 4 is fused, but one could use a tank supplied with alloy 4 previously melted, this supply being for example continuous.
  • the installation 21 has been described outside the drum 11, but the invention retains its interest if there is inside the drum 11, the means making it possible to obtain the jet 7, using a length L more reduced, for example of the order of 2 cm, which still allows great flexibility in the adjustment of the casting, while thermally and mechanically protecting these means.
  • the device 60 represented in FIG. 6 comprises the installation 21 previously described and the belt 61 supported by the rollers 62.
  • FIG. 6 is a section made along the length of the belt 61
  • FIG. 7 represents a part of the belt 61 in cross section, the section plane of FIG. 7 being shown diagrammatically by the straight line segments VII-VII in FIG. 6.
  • the rollers 62 allow the belt 61 to move, at the top, in the direction of arrow F60, this arrow being inclined downwards.
  • a coolant 9 for example water
  • a coolant 9 is made to arrive at the top of the upper part of the belt 61, by the tube 66.
  • the water 9 is driven by the belt 61 downwards, at the same speed as this belt, and thus forms a layer 67 in the channel 64.
  • the water 9 then flows into the tank 68, this flow being shown diagrammatically by the arrow F 60b .
  • the water 9 is then brought back to the tubing 66 by means of the pump 69 in order to be again poured onto the belt 61.
  • the installation 21 makes it possible to introduce the jet 7 into the layer 67 where it is quickly quenched to give the amorphous wire 12.
  • the wire 12 flows with the water 9 in the direction of the arrow F60 and it is wound up then on the reel 70, in the vicinity of the lower part of the belt 61.
  • oxidizing gases can be used than the hydrogen-water vapor mixture, for example a mixture of hydrogen and carbon dioxide or hydrogen and carbon monoxide, or a mixture of hydrogen with at least two oxidizing compounds chosen from water vapor, carbon dioxide, carbon monoxide; it is also possible to use, for example, as an oxidizing gas, oxygen, or a mixture containing oxygen, for example air;
  • Hydrogen can also be replaced by another gas, for example an inert gas, in particular nitrogen or argon;
  • the protection of the nozzle can be ensured by gases other than hydrogen, one can even consider dispensing with such protection, if the nozzle is resistant with respect to the gaseous atmosphere capable of stabilizing the jet ; in this case, for alloys whose stabilization of the jet is difficult to achieve, it may be advantageous to introduce the oxidizing gas in contact with the jet directly at the outlet of the nozzle;
  • oxidation for example a mixture of hydrogen and carbon dioxide or hydrogen and carbon monoxide, or a mixture of hydrogen with at least two oxidizing compounds
