Definitions
- the invention relates to a holding furnace with metering device for molten metal, in particular for metering of molten metal during die casting.
- the DE-OS 2022989 describes an automatic dosing device for liquid metals with which metal melts should be precisely metered.
- the automatic dosing unit is part of a holding furnace, which is fed with molten metal via a loading flap.
- the discharge of the melt to be metered takes place through a delivery tube, which is provided with two measuring electrodes. If melt is to be metered, the furnace is pressurized with compressed air and the melt rises in the delivery tube until it reaches the measuring electrodes and thus delivers a pulse to a controller.
- the discharge pipe discharges the set amount of molten metal. Thereafter, the oven is vented over a timer and the flow of molten metal abruptly prevented.
- the accuracy is insufficient for today's conditions and the formation of slags is disadvantageous.
- Another device for casting molten metal according to the DE-A-19821650 comprising a metering container, which is connected via a closable opening with the melting space of a holding furnace in flow communication.
- the dosing is emptied by pressurized gas via a riser, wherein the opening is arranged in the bottom of the dosing and can be closed from the inside by means of a valve body to a valve rod.
- the opening is hemispherical or conical.
- Valve rod and valve body are arranged inside the metering container.
- the level in the dosing tank is determined by means of a level sensor in the dosing tank.
- the melt flows independently up to the predefined working level via the open bottom valve into the dosing tank. After reaching the target level, the opening of the bottom valve by lowering and turning the valve body locked. By means of a defined gas overpressure, the melt leaves the dosing tank through the riser. Reflux in the riser is possible when refilling the dosing tank. As a result, unwanted oxides can be deposited in the riser.
- the DE-A-10034946 discloses a piston pump whose valve unit is used in combination as an inlet and outlet valve. Such a valve is trapped geometrically and therefore can not be dismantled without expensive cleaning of the piston pump.
- a holding furnace, especially for light metal melts is in the JP-A-2001239357 disclosed.
- a separate metering chamber with a closable opening, which opens into a riser pipe to the point of use.
- the outlet is closable by means of a valve rod, wherein the closure elements must cooperate in the metering chamber.
- the invention is based on the object to provide a holding furnace with a metering device for molten metal, in which, while avoiding the disadvantages of the prior art, a precise metering of molten metals, in particular aluminum melt is possible.
- the solution of the issue is based on the features of claim 1.
- Characteristic is a controlled outlet valve of a pneumatically operated metering chamber in conjunction with contact electrodes or alternative level sensors for molten metal.
- the metering chamber is rotatably and tiltably mounted with the delivery pipe in the holding furnace.
- This outlet valve not only prevents the backflow of melt from the riser, but also increases the dosing accuracy, since no inconstant flow obstacles interfere with the pneumatic metering.
- the melt level in the riser can be kept high, close to the outlet. Oxides can only slightly contaminate the riser and the outlet valve.
- a rotatable and tiltable Dosierhunthalterung allows the fixed to the metering chamber connected delivery pipe a much better adaptation to the geometric conditions of the casting chamber to be filled, eg a die casting machine.
- a decoupling of the dosing unit can be achieved by the casting chamber exposed to strong vibrations via a small tilting movement.
- a docking has a positioning aid in the form of a ceramic bushing, in particular of a fiber-reinforced ceramic material.
- This ceramic bushing fits into an opening of the casting chamber, so that an accurate dosing from below is possible.
- the docking is still stored in a dome of the conveyor tube, which still contains a sealing element.
- This arrangement allows both an angle compensation and the compensation of an axial offset up to ⁇ 2 mm.
- the opening is designed as a socket, which is accommodated in a bush made of gray cast iron.
- the conveyor pipe is provided with a heater and a foamed insulation.
- a ceramic sealing ring is arranged, which is still surrounded by a steel ring, which ensures a rapid removal of heat energy at the transition.
- the durability is increased and the handling is simplified.
- a holding furnace 1 for example, aluminum melt consists in a conventional manner from a force-absorbing steel tub 2 with a heat-resistant insulation 3. The heating is done by a not explicitly shown ceiling, immersion or floor heating. The holding furnace 1 is filled to a minimum level 4 with aluminum melt.
- a metering chamber 8 In a further opening of the steel tub 2, a metering chamber 8 is arranged, in which there is a metering device for each pouring amount of molten metal to be metered.
- the metering device contains an outlet valve with a valve rod 11 and a valve seat 12.
- the valve seat 12 establishes the connection to a riser 20.
- the valve rod 11 is held at the upper end in a gas-tight and heat-resistant bellows 18 and guided and driven by pneumatic cylinder 17.
- this valve drive unit may be an analog gas-tight drive unit for the active actuation of two scanning electrodes 16 and 16'befinden.
- molten metal is sucked pneumatically via a bottom valve (passive inlet valve 13) and / or an overflow 14 into the dosing chamber 8.
- a bottom valve Passive inlet valve 13
- an overflow 14 or an active or passive bottom valve 13 prevent or limit the reflux of molten metal from the metering chamber 8 in the holding furnace 1.
- After opening the outlet valve 11,12 molten metal can be pneumatically conveyed via the riser 20 to the casting machine. After reaching the metered amount, the valve rod 11 closes the valve seat 12 and thereby terminates the metering exactly. A possible reflux of molten metal from the riser 20 into the metering chamber 8 is reliably prevented.
- the melt level (melt surface 15) can be easily overflowed, which can increase the dosing accuracy.
- the riser 20 is connectable via a conveyor pipe 21 with an outlet beak 22 and a docking 23 with the casting chamber 24.
- the docking 23 has an angle-independent and laterally displaceable positioning aid in the form of a cap 44.
- a ceramic bushing 41 is used as insulation, which allows accurate metering from below by avoiding solidification.
- a sealing element 45 is installed between the delivery pipe 21 and the cap 44. This arrangement allows both an angle compensation and the compensation of an axial offset up to ⁇ 2 mm.
- the opening 43 of the casting chamber 24 is designed as an exchangeable bushing 42 (welding bushing). It is manufactured in gray cast iron, which allows inexpensive replacement parts with good resistance to melting.
- the delivery pipe 21 is provided with a heater 52 and a foamed insulation 51.
- a ceramic sealing ring 53 is disposed between the conveyor pipe 21 and holding furnace 1, which is still surrounded by a steel ring 54, which ensures a rapid removal of heat energy at the transition.
- the escaping molten metal selectively solidifies in the event of a leak, which ensures good durability of the connection and simplifies handling.
- metering device including conveying tube 21 is rotatably and tiltably inserted into the holding furnace 1.
- a turning and tilting device is a rotary arm 30 in which a tilting ring 31 is used with built-dosing 8.
- the bainauerabstützung 32 is rigidly connected to this tilting ring 31. Forces acting on the conveyor tube 21 are translated as quickly as possible into a movement of the turning and tilting device, which reduces the load on the delivery tube 21 and thereby increases the durability.
- the holding furnace 1 may be arranged on a lifting device in the form of a scissors jack. Since the operating cylinder for the scissor lifter can be arranged laterally on the outside of the steel tub 2, the minimum overall height of the scissors lifter can be kept low.
