Description
本発明は、鋳造部品、好適にはダイカスト部品鋳造用の、固形物が混入された金属または金属合金、好適には軽金属または軽金属合金を製造するための方法および装置であって、溶融装置を用いて、金属または金属合金を溶融するステップと、鋳造用溶融物を送り導管を介して、充填されるべき鋳型へ搬送するステップと、送り導管において鋳造用溶融物を搬送する間に鋳造用溶融物に固形物を供給するステップと、を含む方法および装置に関する。 The present invention is a method and apparatus for producing a solid-enriched metal or metal alloy, preferably a light metal or light metal alloy, for casting a cast part, preferably a die cast part, using a melting apparatus. Melting the metal or metal alloy, transporting the casting melt via a feed conduit to the mold to be filled, and casting the melt during transport in the feed conduit. Supplying solid matter to the apparatus.
従来技術から、機械的な強度等の物理的な特性を改良するため、または耐久性を改良するためにも、粒子を添加することによる複合材料の製造方法が知られている。また、特に軽金属溶融物の場合には、大きな接触角による固形物の注入における挑戦も知られている。 From the prior art, there is known a method for producing a composite material by adding particles in order to improve physical properties such as mechanical strength or to improve durability. There are also known challenges in the injection of solids with large contact angles, especially in the case of light metal melts.
特に非金属の固形物の場合、溶融物における大きな接触角に基づく固形物の劣悪な濡れ特性は、劣悪なマトリックス結合と同じ意味を持ち、これは、金属または金属合金内への固形物の包込みを困難にする。さらに、このようなプロセスは極めて手間がかかる。 Particularly for non-metallic solids, the poor wetting properties of the solids due to the large contact angle in the melt have the same meaning as the poor matrix bonding, which is the encapsulation of the solids in the metal or metal alloy. Make it difficult to include Furthermore, such a process is very laborious.
米国特許第７５０９９９３号明細書に開示された方法では、鋳造用溶融物がまだ溶融炉内で液状である間に粒子を添加する。しかしながらこれは、型に充填するまでのプロセスが非連続的であり、むしろその都度１回分の炉バッチ処理量しか流し込むことができず、この場合、炉バッチ処理量は、バッチ毎に繊維と溶融物とのそれぞれ異なる割合（比率）を有している、という欠点をもたらす。さらに、沈殿の可能性も生じる。なぜなら、鋳造用溶融物の流込み中には、混合がほとんど行われないからである。 In the method disclosed in US Pat. No. 7,509,993, particles are added while the casting melt is still liquid in the melting furnace. However, this means that the process up to filling the mold is discontinuous, but rather only a single batch of the furnace batch can be poured in each case, in which case the batch batch of the furnace and the melt It has the disadvantage that it has a different ratio (ratio) to the object. In addition, there is the possibility of precipitation. This is because during the pouring of the casting melt, little mixing takes place.
本発明の課題は、固形物を金属または金属合金内へ包み込むと共に、固形物の良好な濡れ、クラスタ形成無しでの均質な混合、および連続的な製造プロセスの保証の達成を可能にする方法、ならびにこの方法と結び付けられた装置を提案することにある。 The object of the present invention is to provide a method for encapsulating solids in metals or metal alloys, while achieving good wetting of the solids, homogeneous mixing without cluster formation, and guaranteeing a continuous production process, And to propose a device associated with this method.
この課題は、本発明に基づき、混合ゾーンにおける搬送中に、好適にはエネルギ入力により、供給された固形物を鋳造用溶融物に混合し、かつ送り導管にミキサを配置することによって解決される。 This object is achieved according to the invention by mixing the supplied solids with the casting melt during transport in the mixing zone, preferably by means of energy input, and arranging a mixer in the feed conduit. .
本発明による方法は、鋳造部品、好適にはダイカスト部品鋳造用の、固形物が混入された金属または金属合金、好適には軽金属または軽金属合金の製造方法に関する。 The method according to the invention relates to a method for the production of solids-mixed metals or metal alloys, preferably light metals or light metal alloys, for casting cast parts, preferably die-cast parts.
最初に、金属または金属合金を、金属または金属合金が液状に移行して鋳造用溶融物になるまで溶融させる。 First, the metal or metal alloy is melted until the metal or metal alloy transitions to a liquid state and becomes a casting melt.
鋳造用溶融物を、送り導管を介して、充填されるべき鋳型に運ぶ。これは好適には、送り導管の勾配によってかつ／またはポンプを用いて行われてよい。鋳造用溶融物の送りに関して特に好適なのは、電磁ポンプである。 The casting melt is conveyed via a feed conduit to the mold to be filled. This may preferably be done by the gradient of the feed conduit and / or by means of a pump. Particularly suitable for feeding the casting melt is an electromagnetic pump.
固形物を鋳造用溶融物内へ供給するために、送り導管における送り中に、調量装置を介して、固形物が鋳造用溶融物内へ注入される。固形物の均質な混合ならびに最適な濡れを保証するために、鋳造用溶融物には、送り導管内での搬送中または送り中に、混合ゾーン内で、好適にはエネルギ入力によって固形物が混合され、この場合、混合ゾーンは、調量装置の領域において固形物が注入されるすぐ傍に配置されていてもよい。 To feed the solids into the casting melt, the solids are injected into the casting melt via a metering device during the feed in the feed conduit. To ensure a homogeneous mixing of the solids as well as an optimal wetting, the casting melt is mixed with the solids in a mixing zone, preferably by energy input, during transport or feeding in the feed conduit. In this case, the mixing zone may be arranged in the area of the metering device immediately after the solids are injected.
混合が、固形物の供給中および／または固形物の供給後に行われると有利である。最適な混合により、固形物のクラスタ形成が阻止されると共に、鋳造用溶融物に対する固形物の結合および濡れ特性が改良される。 Advantageously, the mixing takes place during and / or after the supply of the solids. Optimum mixing prevents solids from clustering and improves the bonding and wetting properties of the solids to the casting melt.
１つの好適な実施形態は、混合用のエネルギ入力が、少なくとも１つの混合ゾーン内で超音波ソノトロードを用いて行われる点にある。これは、形成された固形物凝集体が、超音波により、供給されるエネルギとパルスとを用いて分離され、これにより、個々の固形物が鋳造用溶融物に、より良好に結合することができるようになることによって、鋳造用溶融物に対する固形物の結合を改良する。さらに、固形物と鋳造用溶融物との間の接触角も減少し、これもやはり、改良された結合に寄与する。 One preferred embodiment is that the energy input for the mixing is performed using an ultrasonic sonotrode in at least one mixing zone. This means that the solid agglomerates formed are separated by ultrasonic waves using the supplied energy and pulses, which allows the individual solids to better bind to the casting melt. Being able will improve the bonding of the solid to the casting melt. In addition, the contact angle between the solid and the casting melt is also reduced, which again contributes to an improved bond.
エネルギ入力、好適には超音波を用いることによる別の利点としては、鋳造用溶融物上に位置し、表面張力に基づき固形物の侵入を防ぐ酸化物層が分離され、これにより、固形物は鋳造用溶融物中へ、より良好に侵入することができるようになる。 Another advantage of using energy input, preferably ultrasound, is that the oxide layer located on the casting melt, which prevents solids from penetrating based on surface tension, is separated so that the solids It can better penetrate into the casting melt.
鋳造用溶融物の供給が送り導管内で連続的に行われると有利であることが判った。これにより、連続的で継続的なプロセスならびに高い効率を保証することができる。 It has proven advantageous if the supply of the casting melt takes place continuously in the feed conduit. This ensures a continuous and continuous process as well as high efficiency.
好適には、固形物は繊維および／または粒子として形成されており、この場合、繊維は細長い形状を有しており、粒子はどちらかといえば球状または薄片状に形成されている。 Preferably, the solids are formed as fibers and / or particles, where the fibers have an elongated shape and the particles are rather spherical or flaky.
繊維または粒子が、炭素繊維、酸化アルミニウム、玄武岩、炭化ケイ素、アラミド、金属繊維、コーティングされた繊維および／またはこれらの派生物の群に由来するものであると有利である。試験から、これらの繊維および薄片または粒子は良好な耐熱性を有しており、高温に温度調節された鋳造用溶融物中で燃え尽きないということが判った。 Advantageously, the fibers or particles are from the group of carbon fibers, aluminum oxide, basalt, silicon carbide, aramid, metal fibers, coated fibers and / or derivatives thereof. Tests have shown that these fibers and flakes or particles have good heat resistance and do not burn out in the casting melt, which has been thermostated at high temperatures.
１つの好適な実施形態は、送り導管が温度調節されるという点にある。送り導管を介した異なる温度調節の可能性に基づき、鋳造用溶融物の状態に影響を及ぼすことができる。つまり、例えば送り導管を冷却可能であることにより、鋳造用溶融物は積極的に冷却されることになり、鋳造用溶融物の状態が半固体になるか、または金属または金属合金の半固体範囲内にあることになる。もちろん、鋳造用溶融物を液状にするか、または液状に保つために、送り導管を加熱する可能性もある。 One preferred embodiment is that the feed conduit is thermostated. Due to the possibility of different temperature adjustments via the feed conduit, the condition of the casting melt can be influenced. That is, for example, by being able to cool the feed conduit, the casting melt will be actively cooled, and the state of the casting melt will be semi-solid, or a semi-solid range of metal or metal alloy. Will be within. Of course, it is also possible to heat the feed conduit in order to make the casting melt liquid or keep it liquid.
鋳造用溶融物が半固体状態になるまで、搬送中に鋳造用溶融物が送り導管内で冷却されると有利である。半固体状態に基づき、固形物を練り込むことが可能になり、これもやはり、固形物と合金との間の結合を改良する。特定の範囲にわたり、鋳造用溶融物の同一状態を有しひいては適宜に固形物を注入することができるようにするか、または、固形物と金属または金属合金との間の結合が、例えば練込みまたは超音波処理を用いて改良されるようにするためには、ある程度の温度レベルに温度が保たれると有利である。 It is advantageous if the casting melt is cooled in the feed conduit during transport until the casting melt is in a semi-solid state. Based on the semi-solid state, it becomes possible to knead the solids, which also improves the bond between the solids and the alloy. Over a certain range, the casting melt has the same state and thus can be appropriately injected with solids, or the connection between the solids and the metal or metal alloy is, for example, kneaded Alternatively, in order to be improved using sonication, it is advantageous if the temperature is kept at a certain temperature level.
本発明は、固形物が混合ゾーンにおいて半固体状態の鋳造用溶融物中に練り込まれるようになっている、別の構成において優れている。練込みは、好適にはやはり送り導管に配置された別の混合ゾーンにおいても実施される。 The invention is distinguished in another configuration in which the solids are kneaded into the semi-solid casting melt in the mixing zone. The kneading is also carried out in a separate mixing zone, preferably also located in the feed conduit.
鋳造部品、好適にはダイカスト部品鋳造用の、固形物が混入された金属または金属合金、好適には軽金属または軽金属合金を製造するための本発明による装置は、内部で金属または金属合金が溶融される溶融装置を有しており、このためには好適には炉が使用される。鋳造用溶融物を送るまたは搬送するために、本装置は送り導管を有している。本発明による装置の調量装置は、鋳造用溶融物中への固形物の供給に用いられ、調量装置は送り導管に接続されている。本発明による装置は、鋳造用溶融物を均質に混合するために少なくとも１つのミキサを有しており、ミキサは送り導管に配置されており、鋳造用溶融物の混合は、搬送または送り中に行われる。 An apparatus according to the invention for producing solid-contaminated metals or metal alloys, preferably light metals or light metal alloys, for casting cast parts, preferably die cast parts, comprises a metal or metal alloy in which the metal or metal alloy is melted. A melting apparatus, for which a furnace is preferably used. To feed or transport the casting melt, the apparatus has a feed conduit. The metering device of the device according to the invention is used for feeding solids into the casting melt, the metering device being connected to the feed line. The device according to the invention has at least one mixer for homogeneously mixing the casting melt, the mixer being arranged in a feed conduit, wherein the mixing of the casting melt is carried out during transport or feeding. Done.
ミキサが超音波ソノトロードとして形成されていると有利である。好適には液状の鋳造用溶融物中で超音波を用いて固形物を混合することにより、上述したような様々な理由から、鋳造用溶融物と固形物との間の結合が改良される。 Advantageously, the mixer is formed as an ultrasonic sonotrode. Mixing the solids, preferably in a liquid casting melt, using ultrasonics improves the bond between the casting melt and the solids for a variety of reasons as described above.
送り導管に、鋳造用溶融物を圧送するためのポンプ、好適には電磁ポンプが配置されていると有利であることが判った。これは、鋳造用溶融物の連続的で制御可能な搬送または圧送を保証する。 It has proved advantageous if a pump, preferably an electromagnetic pump, for pumping the casting melt is arranged in the feed line. This ensures a continuous and controllable transport or pumping of the casting melt.
送り導管がバイパス導管を有していると好適な実施形態であることが判った。この場合、バイパス導管は、注入・混合ゾーンを通る鋳造用溶融物の複数回の通走を可能にする。これは、供給されるまたは供給しようとする固形物量ならびに混合の高いフレキシビリティを可能にする。好適には、バイパス導管も温度調節可能である。 It has been found that the preferred embodiment is for the feed conduit to have a bypass conduit. In this case, the bypass conduit allows multiple passes of the casting melt through the injection and mixing zone. This allows a high amount of solids to be supplied or to be supplied as well as a high degree of mixing. Preferably, the bypass conduit is also temperature-adjustable.
好適には、調量装置は鋳造用溶融物中に固形物を注入するためのインジェクタを有している。これは、鋳造用溶融物中への連続的な固形物注入を保証する。 Preferably, the metering device has an injector for injecting solids into the casting melt. This ensures a continuous solids injection into the casting melt.
送り導管が、調量装置の範囲に管狭小部を有していると有利である。これは、より狭い範囲におけるより低い圧力を可能にし、これにより、調量装置内の固形物が吸引力により連行される。 It is advantageous if the feed conduit has a pipe narrowing in the region of the metering device. This allows a lower pressure in a narrower range, whereby the solids in the metering device are entrained by suction.
本発明による金属または金属合金は、好適には鋳造部品、特にダイカスト部品の製造に用いられ、この場合、好適には鋳造部品は車両部品として使用される。もちろん、別の使用分野も考えられる。対応する金属または金属合金の組成は、用途および要求に合わせられ、これに対応して、適当な固形物が与えられる。 The metal or metal alloy according to the invention is preferably used for the production of cast parts, in particular die-cast parts, in which case the cast parts are preferably used as vehicle parts. Of course, other fields of use are also conceivable. The composition of the corresponding metal or metal alloy is tailored to the application and requirements and correspondingly gives a suitable solid.
あらゆる構成手段が互いに自由に組合せ可能であり、本方法の特徴は、本装置の特徴および使用の記載と同様に、互いに自由に組合せ可能である。 All components can be freely combined with one another, and the features of the method can be freely combined with one another, as well as the description of the features and uses of the device.

図１に示す図面には、固形物が混入された金属または金属合金を製造するための、本発明による装置１が示されている。装置１は、溶融装置２、好適には金属および金属合金を溶融するための炉を有している。これにより得られた鋳造用溶融物は、送り導管３を介して、充填されるべき鋳型９に運ばれる。 In the drawing shown in FIG. 1, an apparatus 1 according to the invention for producing a metal or metal alloy mixed with solids is shown. The device 1 comprises a melting device 2, preferably a furnace for melting metals and metal alloys. The casting melt thus obtained is conveyed via the feed conduit 3 to the casting mold 9 to be filled.
好適には、送り導管３における鋳造用溶融物の送り用には、鋳造用溶融物の一定で好適には連続的な流れが送り導管３を通流することを保証するポンプ１１が使用される。送り導管３には、固形物、好適には粒子または繊維を鋳造用溶融物中に注入する調量装置４が配置または接続されている。固形物と鋳造用溶融物との混合用に、少なくとも１つのミキサ５が送り導管３に配置されており、複数のミキサ５が、送り導管３の複数の異なる位置に配置されていてもよい。好適には、調量装置４の領域に既に、好適には超音波ソノトロードとして形成された１つのミキサ５が位置しており、好適にはまだ液状の鋳造用溶融物における固形物の混合を保証している。代替的に、相応のミキサ５を備えた別の混合ゾーン６が送り導管３に配置されていてもよく、別の混合ゾーン６でも、好適には鋳造用溶融物が半固体状態でありかつミキサ５を用いて練り込まれると、鋳造用溶融物がやはり混合されることになり、これは、鋳造用溶融物に対する固形物の良好な結合を可能にする。鋳造用溶融物の最適な状態を保証するために、送り導管３は、加熱によってにせよ、または冷却によってにせよ、適宜に温度調節可能であり、これは個別に対応して適用可能である。可能な実施形態として、送り導管３にはバイパス導管８が配置されており、バイパス導管８は、送り導管３における注入・混合ゾーン７を鋳造用溶融物が複数回通走することを可能にし、このようにして鋳造用溶融物には、この鋳造用溶融物が所望の組成を有すると共に十分に混合され、次いで鋳型９内へ充填されるまで、固形物が相応に供給されるようになっている。 Preferably, for feeding the casting melt in the feed conduit 3, a pump 11 is used which ensures that a constant and preferably continuous flow of the casting melt flows through the feed conduit 3. . A metering device 4 for injecting solids, preferably particles or fibers, into the casting melt is arranged or connected to the feed conduit 3. At least one mixer 5 is arranged in the feed conduit 3 for mixing the solids and the casting melt, and a plurality of mixers 5 may be arranged in a plurality of different positions of the feed conduit 3. Advantageously, in the area of the metering device 4 there is already a mixer 5, preferably formed as an ultrasonic sonotrode, which ensures mixing of the solids in the preferably still liquid casting melt. are doing. Alternatively, a further mixing zone 6 with a corresponding mixer 5 can be arranged in the feed line 3, where the casting melt is preferably in the semi-solid state and the mixer When kneaded with 5, the casting melt will still be mixed, which allows for a good bond of the solid to the casting melt. In order to ensure an optimal condition of the casting melt, the feed line 3 can be adjusted in temperature, whether by heating or by cooling, which can be individually adapted. In a possible embodiment, a bypass conduit 8 is arranged in the feed conduit 3, which allows the casting melt to pass through the injection and mixing zone 7 in the feed conduit 3 multiple times, In this way, the casting melt is supplied with a corresponding solid until the casting melt has the desired composition and is well mixed and then filled into the mold 9.
