Definitions
- the melt is from a heated, rotatably mounted sprue consisting of heated shell molds and the outer shape of the projecting components corresponding molds via outlet openings fed.
- the molds are with respect to the associated outlet opening permanently set.
- Such manufactured by investment casting components are therefore subsequently by a so-called To remunerate HIP procedures.
- a hot isostatic pressing process are to compact G telllunker and by a subsequent heat treatment to stabilize the structure of the component produced by casting.
- this object is achieved according to the invention solved by a process for dimensional precision investment casting of components made of non-ferrous metal alloys, with the outer shape of the respective components to be produced, from heated Formschaten existing molds, which melt from a heated rotatably mounted sprue device is supplied via outlet openings, wherein the spatial angle of the Molds adjustable with respect to the respectively associated outlet opening are and are chosen such that a complete filling about acceleration forces including the Coriolis forces of the melt-pronounced centrifugal forces he follows.
- the melt for the casting process in the sprue by means of the centrifugal forces against the by gravity certain flow direction deflected by approximately 30 ° - 180 ° and the inflow into the molds by the acceleration forces including the Coriolis forces for homogeneous filling of the molds forced.
- the heated rotatably mounted sprue and the heated molds on predetermined, with the non-ferrous metal alloys used for investment casting corresponding, maintaining their fluidity, preferably 10 to 200 ° C above the melting point of the non-ferrous metal alloy Process temperatures held.
- the inventive method has a number of advantages.
- Eingussvorraum a vertical, rotatably mounted cup-shaped container used with aerodynamically trained bottom surface, with at his Jacket surface arranged at a predetermined distance from the bottom surface and with the container via outlet openings communicating molds existing molds means for Heating the sprue and the molds are provided and wherein the molds over means with their spatial angle of attack in relation to the respectively assigned aerodynamically trained; outlet opening in the container are adjustable so that a homogeneous mold filling without Stalls of the melt takes place.
- containers and molds consist container and Molds of low-melting ceramic with embedded Metal particles, so containers and molds are preferably known inductively per se Inductors or controlled by microwaves exactly controllable heated.
- the supply the melt serving gutter with respect to the melt also streamlined is formed and made against the melt reaction poor heatable Ceramics with embedded metal particles.
- the melt can but according to a further embodiment of the invention also within the Container of the sprue device are generated during its rotation.
- fillers and gutters can be made of coated steel, coated Graphite, made of tantalum, titanium or niobium.
- the apparatus of Figure 1 shows a rotatable about an axis 10 in total the reference numeral 11 designated pouring device, the melt of a Ladle 12 via a streamlined trained runner 14 fed becomes.
- the sprue 11 is rotatably mounted vertically standing - the required for this purpose Drive device is not shown for clarity -, and includes a cup-shaped container 15 with a rotationally symmetrical side wall 16 and an integrally formed flow-optimized bottom 18. Im Distance a from the bottom 18 are symmetrical on the circumference of the side wall Distributed 16 fluidically optimized outlet openings 19, which with Half shells 20 existing molds 22 communicate.
- the molds are at spatial angles sr with respect to the associated outlet openings 19 adjustably connected to the container 15.
- the setting of the Angle sr is a function of the specific weights of the non-ferrous metal alloy used, the casting temperature and the speed n of the container and the respective specific weight of the alloy, so that the entire feed fluidics is designed optimized.
- the container 15 and the associated molds 22 are in their predetermined Location by means of a suitable ceramic, serving as a matrix for these Bracket 23 is arranged between a base plate 24 and a cover plate 26 is clamped. Via an opening 28, the heated to casting temperature Melt emerging from the ladle 12 and passed on the trough 14 Melt enter the container 15.
- a suitable ceramic serving as a matrix for these Bracket 23
- the heated to casting temperature Melt emerging from the ladle 12 and passed on the trough 14 Melt enter the container 15.
- heaters 30 - such as Inductors - are both the sprue 11th and runner 14 and the molds 22 so inductively heated that the Melt remains until the completed casting to casting temperature.
- This the fluidity the melt-maintaining temperatures correspond to those for Investment casting used non-ferrous metal alloys.
- containers 14, container 15 and molds 22 from the melt less reactive Ceramic with embedded metal particles can but also made of coated steel, tantalum, titanium or niobium.
- Coriolis force is known as the inertial force, in addition to the manager and the centrifugal force on a moving in a rotating system Body acts.
- the Coriolis force is perpendicular to that of the velocity vector and the axis of rotation formed plane.
- the non-ferrous metal alloy located in the ladle 12 is converted by heating in a conventional manner in the desired melt and passes - As already described - on the heated runner 14 in the rotating also heated sprue 11, where by gravity to the bottom 18 of the Container 15 passes.
- the rotation of the container act on the melt Centrifugal forces, the direction reversal of the flow direction of the melt from approximately 30 ° to 180 °, so that these on the inner wall of the side wall 16 adjoining rises up to the height of the outlet openings 19.
- the spatial Anstellwinkel sr of the molds 22 are selected such that this with the In the direction of the Coriolis force vectors coincide, these act in addition to the Centrifugal forces on the melt, with the result that the melt is not can only enter through the openings 19 in the molds, but that this itself to the openings 19 subsequent cavities of the molds quickly and safe and complete and homogeneous. After solidification of the melt removed the molds and the respective investment casting in the usual way applied.
- the pouring device In the illustrated in Figure 2, generally designated by the reference numeral 40 embodiment the pouring device, of which the pouring device 11 corresponding Components are designated by like reference numerals, which are located in their Angular position sr adjustable, held in the posture 23 22 on upper edge of the now rotatably mounted in the pouring device 11 container 15. This has in this area acting for the melt as a nozzle Distributor 42 on.
- the leading to the interior of the mold 22 outlet openings 19th are - as in the embodiment of Figure 1 - also aerodynamically favorable for the melt educated.
- the non-ferrous metal alloy is here the container 15 as melting in the rotating container supplied so-called ingot, so ladle 12 and pouring 14th of the embodiment of Figure 1 omitted.
- the cover plate 26 is detachable with the pouring device 40 connected. Since the inductively heatable container 15 rotatable by itself is stored in the sprue 40, are temperature-resistant seals 45 between the inlet openings of the stationary molds 22 and the outlet openings 19 of the rotating container 15 is provided.
- the mode of action the sprue device described above corresponds to that in connection with FIG. 1, but with the effect of unfolding the nozzle effect Distributor 42, the supply of the melt in the molds 22 and thus whose filling is favorably influenced.
- the cast components still heated in the molds at 600 to 700 ° C. which is also inductive via the existing heaters 30 he follows.
- the cooling rate of the cast components is controlled kept low for cracks, breaks and the like in the components to avoid.
- the removal The cast components from the molds so takes place only after reaching the each desired degree of cooling, depending on the composition of each used non-ferrous metal alloy is to choose.
- the invention described above ensures for the first time that the Coriolis forces of the melt imparted centrifugal forces specifically also can be effective and apply the melt similar to a plunger and thus urge the melt completely and homogeneously into the mold, this So fill completely and void-free, without a damaging stall the melt and a different solidifying boundary layer formation take place can.
- the cooling rate becomes controlled low, so that the uncontrolled cooling occurring Residual stresses in the components and resulting cracks, fractures etc. be avoided.
