Definitions

  • the invention relates to a method for producing preferably one-piece alloy bodies made of liquid metal, especially one-piece quality alloy bodies made of (aluminum) cast alloys, e.g. B. after DIN 172552.
  • aluminum aluminum
  • - Under quality alloy bodies are in To understand such alloy bodies within the scope of the invention, their alloy components by weight (according to DIN) defined (and reproducible). this will usually in an upstream melting furnace performed.
  • alloys or alloy body made of liquid metal There are numerous manufacturing processes for alloys or alloy body made of liquid metal known from practice. Such alloy bodies become regular produced to again in the subsequent processing melted and brought into the desired (casting) shape to become. Most of them are cuboid for transport Alloy body, e.g. B. ingots weighing 4 to 25 kg, made up in stackable blocks of fixed lot sizes and usually strapped. There are stacking machines for this required, which is designed relatively complex are and do not always work trouble-free. This can be done largely due to the solidification of the Return the liquid metal to the high temperatures. In addition, such stacking machines are expensive built and therefore expensive.
  • liquid metal heat-insulating container directly on for example Deliver foundries. Such procedures are however, it can only be carried out profitably with large quantities of liquid metal. In addition, stockpiling is difficult. - Here the invention seeks to remedy the situation as a whole.
  • the invention is based on the technical problem Process and an apparatus for the production of preferably to specify one-piece alloy bodies made of liquid metal, with the help of such bodies simple and inexpensive can be manufactured and transported.
  • the outflow rate can and / or outflow rate of the liquid metal control or regulate the orifice. This generally happens depending on the Speed of mold shapes and / or size or the weight of the alloy body to be produced. With In other words, the size and / or weight of the Alloy body using the outflow rate, the Outflow rate and the speed of the mold control or regulate.
  • a high speed of mold forms predetermined outflow rate and outflow rate, d. H. Amount of liquid metal per unit of time, i. d. R. too small and light alloy bodies.
  • Their size and / or weight can be metrologically recorded or calculated and leaves increase yourself by either speeding the Mold shapes reduced or - what is better - the outflow rate and / or outflow rate is increased.
  • the Outflow rate can in the simplest case by opening further outlets are enlarged while the Outflow rate best by varying the Liquid level in the pouring trough and thus the hydrostatic pressure in the area of the respective bottom Outflow opening is changed. Of course can additionally or alternatively the size of the respective Outflow opening are adjusted.
  • the level of the liquid metal in the pouring trough mostly without contact using laser beams.
  • the level of the liquid metal in the respective mold form are, namely also contactless by means of Laser beams are scanned.
  • the degree of filling of the Transport container is usually non-contact measured, also according to a preferred embodiment using laser beams. Depending on this degree of filling a successor container is provided.
  • the molds are usually part of one Casting belt and are in connection with this casting belt moved.
  • the casting belt has at least two link chains on the longitudinal edge to which the Molds are connected.
  • These molds are located usually in permanent molds, which in the essentially laid together with an overlap are. Molded-in molds are found in these mold carriers Troughs as said mold forms.
  • cooling devices can be provided with whose help the rate of solidification of the Target liquid metal in the molds leaves. This also makes the temperature of the entire device kept at a certain value so that effects not due to temperature drift or inadmissible heating may occur).
  • the invention also relates to one in patent claim 7 Described device for the production of preferably one-piece alloy bodies according to the pretreated Method.
  • Advantageous embodiments of this device are the subject of claims 8 to 10.
  • the alloy body 8 molded from liquid metal, at which is a according to the embodiment Quality alloy made of aluminum.
  • This Liquid metal is fed via a connected supply line 1 filled or fed into a casting trough 2.
  • This Pouring trough 2 has outlet openings 3 at the bottom
  • These outflow openings are ceramic Casting nozzles 3, which are interchangeable according to the embodiment are designed.
  • outflow rate and the outflow rate of the liquid metal from the casting trough 2 can be varied.
  • the number of ceramic pouring nozzles 3 increases accordingly vary.
  • the casting takes place under the effect of Gravity into the permanent metal molds, the molds or troughs 4. Due to the high thermal conductivity of the Mold 4 is accelerated cooling of solidifying molten metal. In the course of this cooling the filled liquid aluminum experiences a Volume shrinkage of approx. 5 to 8%. Forms at the same time a fine-grained, dense alloy structure with excellent Surface finish. In addition, an esp. given a clean and oxide-free cast because of the liquid metal below its surface at the bottom of the pouring trough 2 through the ceramic pouring nozzles 3 into the mold 4 is released, so that with the ambient atmosphere in Connected liquid surface relevant for the casting is reduced to a minimum. Because unwanted Oxides float on the surface of the liquid metal in the trough 2 and are removed if necessary, consequently interfere with the bottom casting in the troughs 4 Not.
  • the molds or troughs 4 are - as mentioned - a component of mold support bodies 5 into which the troughs 4 are molded.
  • the aforementioned mold support bodies 5 are put together like scales with overlap and each along the longitudinal edge with link chains 6 there connected.
  • As a result of this scale-like abutting it is achieved that from the pouring nozzles or outflow openings 3 dispensed liquid metal continuously into the relevant molds 4 is filled, as is the enlarged section in Fig. 1 makes clear.
  • a roof-like Connecting web 7 is provided, which ensures that a Jet S of liquid metal even when hitting one Gap between the molds 4 perfectly in the associated troughs 4 is directed.
  • the respective transport container 9 is part of a Feeding device 10, with the help of which it is ensured that continuously filled transport container 9 and successor container 9 are provided.
  • This loading device 10 is in the embodiment as a turntable 10 executed with drive 11 and the end of the Casting belt 5, 6 arranged. Of course you can too this loading device 10 also conveyor belts, grippers or the like for the transport container 9 belong.
  • cooling device 12 To accelerate the solidification of the alloy body 8 and / or the entire system, in particular the casting belt 5, 6 To cool, is also a cooling device 12 above the casting belt 5, 6 realized. With the help of this cooling device 12, which in the present case is designed as a cooling fan 12 is consequently the rate of solidification influence the alloy body 8. This also will ensures the cooling of the entire system.
  • the Ensuring alloy body 8 is additionally initially once a measuring device 13 above the trough 2 provided to the level of liquid metal there to capture.
  • This measuring device 13 works without contact and is according to the embodiment as a laser measuring device 13 executed.
  • the level in the Molds or troughs 4 are made with the help of another Measuring device 14, in the present case a level measuring device 14 recorded.
  • This level measuring device 14 is arranged above the casting belt 5, 6 and is used for Determination of the fill level of the mold 4 with Liquid metal.
  • a weighing device and / or scanning device 15 in the area of Feeder 10 realized to fill the or to determine the transport container 9.
  • a scanning device 15 in the present case a non-contact laser measuring device 15, realized. All The aforementioned measuring devices 13, 14, 15 are also like the loading device 10 or its drive 11, the Casting belt 5, 6 or its drive 16 and the cooling device 12 to a control device 17 connected.
