Definitions

  • the invention relates to a method and the device for producing metals or metallic alloys mixed with solids, preferably light metals or light metal alloys for the casting of castings, preferably die-castings, with the steps: Melting of a metal or a metallic alloy using a melting device, transporting the casting melt by means of the delivery line to the casting molds to be filled, supplying solids to the casting melt during the transport of the casting melt in the delivery line.
  • the US 7 509 993 B1 discloses a process in which the particles are added while the casting melt is still in the liquid state in the melting furnace.
  • this has the disadvantage that there is no continuous process until the mold is filled, but rather only one batch of furnace can be cast, which then also has a different ratio (ratio) of fibers to melt per batch.
  • ratio ratio
  • this object is achieved in that the casting melt is mixed with the supplied solids during transport in a mixing zone, preferably by means of energy input, and the mixer is arranged on the delivery line.
  • the method according to the invention relates to a manufacturing method of metals or metallic alloys mixed with solids, preferably light metals or light metal alloys for the casting of castings, preferably diecastings.
  • the metal or metal alloy is melted until the metal or metal alloy changes to the liquid state and is present as a casting melt.
  • the casting melt is transported by means of a delivery line to the casting molds to be filled, which can preferably be done via a gradient of the delivery line and / or by means of a pump.
  • An electromagnetic pump is particularly preferred for conveying the casting melt.
  • the solids are introduced into the casting melt via a dosing system during the conveying in the delivery line.
  • the casting melt is mixed with the solids during transport or conveying in the delivery line in a mixing zone, preferably by means of energy input, the mixing zone also being introduced directly into the metering system when the solids are introduced can be arranged.
  • a preferred embodiment consists in that the energy input for thorough mixing takes place in at least one mixing zone by means of an ultrasonic sonotrode.
  • This improves the binding of the solids to the casting melt by separating the agglomerations of the solids formed by the ultrasound by means of the energy and the impulses supplied, thereby allowing the individual solids to bind better to the casting melt and reducing the wetting angle between the solid and the casting melt, and this in turn contributes to a better connection.
  • the energy input preferably by means of ultrasound, the oxide layer, which is located on the casting melt and prevents the penetration of the solids due to the surface tension, is separated, as a result of which the solids can penetrate the casting melt better.
  • the solids are preferably designed as fibers and / or particles, fibers having an elongated shape and particles being more spherical or flake-shaped.
  • the fibers or particles come from the group of carbon fibers, aluminum oxides, basalt, silicon carbide, aramid, metallic fibers, coated fibers and / or their derivatives. Tests have shown that these fibers and flakes or particles have good temperature resistance and do not burn up in the high-temperature casting melt.
  • a preferred embodiment is that the delivery line is tempered. Due to the possibility of different temperature control via the delivery line, the conditions of the pouring melt can be influenced. That means, for example, the delivery line can be cooled, whereby the casting melt is actively cooled and the condition of the casting melt becomes semi-solid or lies in the semi-solid area of a metal or a metal alloy. Of course, there is also the possibility of heating the delivery line in order to bring the casting melt into the liquid state or to keep it there.
  • the casting melt is cooled in the delivery line during transport until the casting melt has a semi-solid state.
  • the semi-solid state enables the solids to be kneaded, which in turn improves the connection between the solids and the alloy.
  • the temperature is kept at a certain temperature level in order to have the same state of the casting melt over a certain range so that the solids can be introduced accordingly or the connection between solids and metal or metallic alloy is improved, for example by kneading or sonicate with ultrasound.
  • the invention is characterized by a further embodiment in which the solids in the casting melt are kneaded in the semi-solid state in a mixing zone. Kneading is preferably implemented in a further mixing zone which is preferably also arranged on the delivery line.
  • the device according to the invention for the production of metals or metallic alloys mixed with solids, preferably light metals or light metal alloys for the casting of cast parts, preferably die-cast parts, includes a melter in which the metal or the metallic alloys are melted, preferably an oven is used for this purpose.
  • the device contains a delivery line for conveying or transporting the casting melt.
  • the metering system of the device according to the invention serves to feed the solids into the casting melt, the metering system being connected to the delivery line.
  • the device according to the invention contains at least one mixer for homogeneous mixing of the casting melt, the mixer being arranged on the conveying line and the mixing of the casting melt taking place during transport or conveying.
  • the mixer is designed as an ultrasound sonotrode.
  • a pump for conveying the casting melt is arranged on the delivery line, preferably an electromagnetic one Pump. This ensures a continuous and controllable transport or conveyance of the casting melt.
  • the delivery line has a bypass line
  • the bypass line allowing multiple runs of the casting melt through the introduction and mixing zone. This enables a high degree of flexibility in the amount of solids supplied or to be supplied, as well as the mixing.
  • the bypass line can preferably also be tempered.
  • the metering system preferably has an injector for introducing the solids into the casting melt. This ensures a continuous introduction of solids into the casting melt.
  • the delivery line has a pipe constriction in the area of the metering system. This enables a lower pressure in the narrower area, whereby the solids that are present in the dosing system are drawn in by suction.
  • the metal or the metallic alloy according to the invention is preferably used for the production of cast parts, in particular die cast parts, the cast parts preferably being used as vehicle parts.
  • the composition of the corresponding metal or a metallic alloy is to be matched to the application and the requirements and to be provided with the appropriate solids.
  • Fig. 1 a device according to the invention for the production of metals or metallic alloy mixed with solids.
  • the drawing shown shows a device 1 according to the invention for producing metals or metallic alloys mixed with solids.
  • the device 1 has a melting device 2, preferably a furnace for melting metals and metallic alloys.
  • the casting melt thus obtained is transported by means of the conveying line 3 to the casting molds 9 to be filled.
  • a pump 11 is preferably used to convey the pouring melt in the delivery line 3, which ensures that a constant and preferably continuous flow of the pouring melt flows through the delivery line 3.
  • a metering system 4 Arranged on the delivery line 3 or connected to it is a metering system 4 which introduces the solids, preferably particles or fibers, into the casting melt.
  • At least one mixer 5 is arranged on the delivery line 3, it also being possible for a plurality of mixers 5 to be arranged at different points in the delivery line 3.
  • a mixer 5 is preferably already located in the area of the metering system 4 and is preferably designed as an ultrasound sonotrode and ensures that the solid is mixed in the preferably still liquid casting melt.
  • a further mixing zone 6 with a corresponding mixer 5 can also be arranged on the delivery line 3, which in turn mixes the pouring melt, preferably when the pouring melt is in a semi-solid state and is kneaded by means of mixer 5, which ensures good binding of the solids the casting melt granted.
  • the conveying line 3 can be appropriately temperature-controlled, whether by heating or by cooling, this can be used individually accordingly.
  • a bypass line 8 is arranged on the conveying line 3, which enables the pouring melt to pass through the introducing and mixing zone 7 several times on the conveying line 3 and so the pouring melt is appropriately provided with solids until the pouring melt has the desired composition and is sufficiently mixed and then filled into the molds 9.
