Definitions

  • the present invention relates to a holding and / or melting furnace for non-ferrous metals, with a metering device for automatically removing a predetermined amount of the non-ferrous metal melt from a metering chamber, which is arranged in the furnace in a stationary manner and with a chamber containing the non-ferrous metal melt At least one inlet opening is connected, which can be closed by a closing piston which contains a compressed gas supply and can be moved to and fro, its reciprocating movement and the supply of the compressed gas being controllable as a function of weight or time.
  • Such furnaces are generally used to scoop out a certain amount of the non-ferrous non-ferrous metal in question and to lead it to a die casting machine.
  • the predetermined amount to be removed depends on the size of the casting to be produced in the die casting machine.
  • the metering chamber is arranged next to the holding chamber and connected to it via a horizontal connecting channel, which at its mouth in the holding chamber can be acted upon by the closing piston. Since the molten metal bath level is significantly higher than the outlet of the dosing chamber, the flow rate or flow rate of the metal flow from the holding chamber to the dosing chamber is regulated either by changing the gas pressure in the closing piston or when the closing piston is raised by the metal melt column in the warming chamber. This means that the dosing chamber is relatively free and therefore needs additional heating. The relatively long and narrow connection channel is also unfavorable, so there is a risk of blockages. Since the dosing chamber with its attached mold is constantly under pressure, it must be provided with a special, openable closure.
  • the object of the present invention is therefore to create a holding and / or melting furnace for non-ferrous metals of the type mentioned, the metering chamber of which is arranged more protected inside the furnace and in which the risk of blockages is avoided.
  • a holding and / or melting furnace for non-ferrous metals of the type mentioned at the outset in that the metering chamber is integrated in the furnace underneath an intermediate chamber connected to a holding chamber and forms part of a furnace trough and that the integrated metering chamber has one inclined riser pipe of predetermined flow cross-section opens directly or centrally via an outlet trough and a tapered pouring end of the furnace.
  • the metering chamber is provided simultaneously with the manufacture of the furnace trough and at the same time at the most convenient location for the operation, both with regard to the non-ferrous metal melt removal for metered discharge and with regard to the pouring spout provided in the furnace.
  • the dosing chamber therefore does not need its own heating device.
  • it is filled without pressure so that the dosage itself can be carried out extremely precisely and quickly.
  • Determining the amount to be delivered to the die casting machine i.e. the exact dosage can be controlled according to claim 2 in a particularly simple manner by a timing relay device which can be set to a specific time given a given flow cross-section and a given gas pressure.
  • An inert gas such as nitrogen, is preferably used as the compressed gas, which has the advantage that it is neutral towards the non-ferrous metal melt, in particular the AL melt.
  • the metering device 11, 111 or 111 ' is used to transfer a predetermined amount of a non-ferrous (molten) metal melt 14 from a holding furnace 12 or a combined melting and holding furnace 112 or 112' to a die casting machine 13, 113 and 113 'to promote, in which this amount of non-ferrous metal melt is processed.
  • the metering device 11 can be used not only in connection with a holding furnace 12, but also with a melting furnace or with a combined melting / holding furnace.
  • the holding furnace 12 shown in FIG. 1 has a housing 16 arranged on legs 17, in which a well 15 with three chambers, namely a filling chamber 18, a warming chamber 19 and a scooping chamber 21, is arranged which is well insulated from the outside by means of a heat-resistant lining.
  • a cover 22 is arranged, on the inside of which in the area above the holding chamber 19 there are arranged electrical heating elements 23 for indirect heating of the non-ferrous metal melt 14.

  • a second partition or barrier 27 is provided between the warming chamber 19 and the scooping chamber 21, which runs under one end of the cover 22 in the form of a crosswise over the tub 15 Bar is arranged, and the free end edge is arranged at a certain distance from the bottom 33 of the chamber 19 or 21.
  • This second barrier 27 is immersed in the non-ferrous metal melt 14 approximately up to half the depth of the trough or chamber.
  • the dosing device 11 with its conveying unit 31 is inserted or immersed in the scooping chamber 21 of the holding furnace 12.
  • the conveyor unit 31 has a housing 32, the base area of which is smaller than that of the scooping chamber 21, and which is seated on the bottom 33 'of the scooping chamber 21.
  • the height of the housing 32 which has an approximately pear-shaped base according to FIG. 3, corresponds approximately to the depth of the scooping chamber 21.
  • the conveyor unit 31 is loosely connected to a weighing device 34, which is provided with a tilting device 36 and via a collecting funnel 37 and an inclined pipeline 38 is connected to the die casting machine 13.

  • the closing piston 46 is a thick-walled tube which is provided with a conical taper at its front end, so that a nozzle-shaped mouthpiece 47 is provided.
  • a closing plate 48 is provided, which is ring-shaped and is held in the form of a cover on the storage chamber 41.
  • the annular closing plate 48 has an access opening 49 which can be closed by the nozzle mouthpiece 47 of the closing piston 46.
  • the inside diameter of the access opening 49 is somewhat larger than the smallest outside diameter of the nozzle mouthpiece 47, so that it can penetrate into the access opening 49 and close with its outer cone.
  • the closing piston 46 and the closing plate 48 are made of highly heat-resistant ceramic.
  • the through bore 51 in the closing piston 46 is connected to a pipeline 52 which is connected via a pressure regulator 53 to a pressure pump or a compressed air network, as is used in companies (FIG. 1).

As can be seen from FIG. 3, these slots 56 are evenly distributed over the circular area of the outer circumference, while the tapering area of the pear-shaped peripheral shape is free of these slots.
  • the slots 56 are conical from the outside to the inside.
  • the vertically extending outlet bore 43 is connected at its end emerging from the housing 32 to a feed pipe 58 made of highly heat-resistant ceramic.
  • the feed tube 58 has a bend of more than 90 ° C. at its end region facing away from the outlet bore 43, in which bend region a ventilation opening 59 is arranged.
  • the free end of the feed tube 58 is arranged above a weighing or receiving bowl 61 of the weighing device 34.
  • the receiving shell 61 is fastened about a horizontal axis 62 to a spring balance 63 which stands on the housing 32 and is fastened to it.
  • the spring balance 63 consists essentially of an upper and outer cylindrical part, to which the receiving shell 61 is attached, and a lower, inner cylindrical part, which is attached to the housing 32.
  • the upper, outer part coaxially overlaps the lower inner part, an adjustable compression spring being arranged between the two, which determines the force that is to be exerted to move the upper outer part downward over the lower inner part.
  • the spring balance 63 or weighing device 34 can thus be adjusted with regard to the metering weight.
  • the spring balance 63 also has, in a manner not shown, two electrical contacts which can be moved relative to one another and come into operative connection and interrupt the melt feed when the set metering weight has been reached.
  • the tiltable receiving shell 61 is provided at one end with a pouring spout 86 and opposite it with a He Belbelgestange 87 connected, the other end is pivotally connected to a pneumatic piston-cylinder unit 88, the fixed end of which is attached to the cylinder 72 or 84 of the weighing device 34.

If this has taken place, preheated compressed air is supplied via the pressure regulator 53 and the pipeline 52 and the central bore 51 in the closing piston 46, so that the non-ferrous metal melt 14 located in the storage chamber 41 is pressurized. The pressure increase is slow and steady. Under this pressure, non-ferrous metal melt 14 is brought through the rising outlet bore 43 into the feed pipe 58 and thus onto the tiltable receiving shell 61.
