Definitions

  • the invention is related to the field of the manufacture of bars or coils through continuous casting of copper alloy with additions of chromium, zirconium, or chromium and zirconium which will be called the "material” in the present document.
  • a particular application of the "material” is the manufacture of welding electrodes.
  • EP 0 142 139 discloses a crucible for a machine for continuously casting a bar or a coil of a metal alloy, including a casting chamber and a primary supply chamber for supplying a molten metal alloy.
  • EP 2 039 444 discloses a process for manufacturing copper alloy worn rod.
  • US 7 036 554 discloses a method and system for casting metal and metal alloys.
  • DE 197 47 002 is related to a three-chamber magnesium melting furnace operating by stepwise temperature increase of the melt, in the flow direction through the chambers.
  • EP1 649 950 provides a continuous casting solution in the manufacture of welding electrodes.
  • a solution is provided for achieving, directly at the exit of the continuous casting, a wire that is sufficiently thin for being passed directly to the cold mill or drawing bench, thus saving the hot extrusion phase.
  • the present invention attempts to cope with at least part of the above-mentioned drawbacks and provides a solution, which permits to obtain the material or any product in form of bars and coils made of an alloy comprising an element highly reactive to oxygen in a hot atmosphere, such as for example magnesium, calcium, lithium or titanium.
  • the invention relates to a crucible for a machine for continuously casting a wire of a metal alloy, including a casting chamber, a primary supply chamber for supplying a molten metal alloy and a channel for transferring said molten metal alloy to the casting chamber.
  • This crucible is particular in that it includes, in addition, a secondary supply chamber configured for supplying the machine with a secondary metal and connected to the primary supply chamber through an interior opening arranged at the lower level of said primary supply chamber, and configured so that, in operation, the separation is complete at the level of the surface of said molten metal alloy in the primary supply chamber.
  • the present invention also relates to a machine for continuously casting a bar or coil made of metal alloy, comprising a crucible according to the invention, and a casting furnace surrounding said crucible, said casting furnace containing, in addition, heating elements made of graphite and a ceramic liner for protecting the top of the crucible ; the heating elements made of graphite permit to heat the crucible for maintaining the molten metal alloy at temperature until the casting, and the ceramic liner protects the top of the crucible against oxidation through contact with the air.
  • the present invention finally relates to a method for manufacturing a bar or coil through continuously casting by means of a machine according to the invention, characterized in that it comprises the following steps :
  • the advantage deriving from the present invention consists in the fact that the additional component highly sensitive to air, like zirconium, is introduced into an oxygen-free molten metal. It is thus preserved in its entirety for forming the finally casted alloy, which permits to control the zirconium content of the alloy, while minimizing the consumption of this metal.
  • the present invention relates to a machine 1 for continuous casting.
  • the machine 1 is described hereafter with respect to a manufacture of electrodes made of an alloy of copper, chromium and zirconium.
  • the specialist in the art will easily be able to adapt the solution to other alloys comprising an element highly reactive to oxygen in a hot atmosphere.
  • This machine 1 includes a crucible 7, with a casting chamber 2 provided with a continuous casting die 3, shown when casting upwards.
  • the invention also encompasses the machines 1 with a different number of dies 3, as well as with horizontal or downward casting dies 3, and it is easy for a specialist in the art to adapt it to this case.
  • the crucible 7 also includes a primary supply chamber 4 configured for supplying the machine 1 with molten metal alloy, in particular copper and chromium. It includes, in addition, a secondary supply chamber 5 configured for supplying the machine 1 with an alloying metal, in particular zirconium.
  • a transfer channel 6 is arranged between the secondary supply chamber 5 and the casting chamber 2 at a level normally covered with liquid metal in operation, said channel 6 permitting that the molten metal passes from the secondary supply chamber 5 to the casting chamber 2, or exceptionally comes back from same, for example during a stoppage of the casting in order to absorb an expansion of the molten metal.
  • the crucible 7 is made of graphite.
  • This material has a first advantage, which is that it withstands high temperatures, in the range of 2000°C, at which the molten metal is present. Nevertheless, at these temperatures it becomes quickly oxidized in the presence of oxygen.
  • a ceramic liner 8 has therefore been arranged on the top of the crucible 7, in order to protect it against room air. Ceramic is a good choice for such a liner because it withstands high temperatures and effectively protects the graphite of the crucible from the oxygen of the air ; however other materials can also be used.
  • This liner 8 can advantageously completely close the casting and supply chambers 2, 4, 5, while leaving only openings 12 necessary for the dies 3, on the one hand, and 13, 14 for the supply, on the other hand of molten metal and alloying metal.
  • this liner 8 may comprise a partition 11 (see fig. 7 ) for separating the primary supply chamber 4 from the secondary supply chamber 5.
  • the liner 8 may alternatively not have such a partition 11, and the separation of the primary supply chamber 4 from the secondary supply chamber 5 is then made by a wall of the crucible 7 itself (see fig. 6 ).
  • An interior opening 21 is provided in both cases, providing a passage between both chambers.
  • the crucible 7 is furthermore placed in a casting furnace 9 provided with heating elements 10 made of graphite.
  • These heating elements 10 are configured to heat the crucible 7 through radiation. They are in turn heated by the passing through of a current and by joule effect.
  • the complete casting furnace 9 is filled with a protective gas, for example nitrogen, which permits to protect both the heating elements 10 and the outside of the crucible 7 against room air, and thus to avoid their accelerated oxidizing.
  • the inside of the crucible 7, forming the casting and supply chambers 2, 4, 5, is protected against the oxygen by the presence of the molten metal.
  • the supply of molten copper and chromium alloy occurs through the primary supply opening 13 of the liner 8 towards the primary supply chamber 4.
  • the copper and the chromium are melted in a melting furnace 20 ( figure 4 ), in which they are subjected to heating and magnetic stirring according to known methods.
  • the melting furnace 20 is designed with a fore hearth 15 for transferring the molten copper-chromium alloy to the primary supply chamber 4, through the primary supply opening 13.
  • the form of the fore hearth 15 and the primary supply opening 13 is such that, during operation, the primary supply opening 13 is « closed » by the fore hearth 15 of the melting furnace 20.
  • the transfer occurs in a nitrogen atmosphere, injected into the primary supply chamber 4, in order to avoid any contact of the liquid alloy with oxygen, and to thus minimize the quantity of oxygen contained in the liquid alloy inside the primary supply chamber 4.
  • the molten metal alloy flows towards the secondary supply chamber 5, passing through the interior opening 21 under the liner partition 11 when present, the surface of the melt in this secondary supply chamber 5 is protected from air with a graphite powder layer.
  • Solid zirconium is simultaneously introduced through the secondary supply opening 14 into the secondary supply chamber 5.
  • the zirconium is heated and melts very quickly, through the conjunction of its low specific heat and its small mass percentage in the alloy. Once it is liquid, the zirconium disperses in the liquid, due to the movements induced by the supply into the two supply chambers 4, 5 and the transfer of the molten alloy through the transfer channel 6.
  • another mixing means like a mechanical stirring means, or an electromagnetic stirring means.
  • zirconium can be introduced by means of a Cu 50% Zr 50% alloy in the form of more or less small particles, and even in the form of powder in a copper alloying tube 19.
  • the supply of liquid copper-chromium alloy is regulated through the opening-closing action of a stopper 16 on a nozzle 17 located at the bottom of the fore hearth 15.
  • the opening is actuated when the level sensor 18 arranged in a supply chamber 4, 5 indicates a predetermined low level
  • the closing is actuated when the level sensor 18 indicates a predetermined high level.
  • the zirconium supply occurs in the secondary chamber 5 in the form of zirconium powder, according to a flow rate adapted to the supply of molten metal alloy into the primary supply chamber 4.
  • the machine 1 can be configured vertically mobile, in order to allow adjustments so as to guarantee a constant level at said die.
  • the advantage of the present invention is that the shape of the liner 8, the primary supply opening 13, the fore hearth 15, the stopper 16 and the nozzle 17 are configured so that in the situation of production:
  • the advantage deriving from the present invention resides in particular in that the zirconium is introduced into an oxygen-free molten metal. It is thus preserved to a maximum for forming the finally casted alloy, which permits to control the zirconium content of the alloy, while minimizing the consumption of this metal.
