Definitions
- the invention relates to a device for introducing metallic ingots into a metal bath, in particular from zinc ingots into a zinc bath, the device having feeding means with which a billet can be fed to the metal bath, and the device having heating means with which the ingot projects and / or heated to a desired temperature during its delivery into the metal bath.
- the strip to be galvanized is passed through a metal bath with a liquid zinc alloy.
- the zinc used for the coating is thereby continuously discharged from the zinc bath. Therefore, zinc must be added to the bath to maintain a constant degree of filling of the zinc bath.
- charging devices are known with which metal billets can be conveyed into the container with the molten metal.
- the temperature of the molten metal is subject to fluctuations with the addition of new ingot material.
- the cold supplied ingot cools the melt in the receptacle, in particular in the region of the addition point, so that the process of the coating can be disturbed.
- JP 1128 1264 A similar solution is known from JP 1128 1264. Again, heat is passed from a melting furnace in the form of hot air to the supplied billets, which are then supplied to the metal bath, if they have a certain temperature.
- the invention is therefore based on the object to remedy this situation and to propose a device for introducing metallic ingots into a metal bath, in which this negative effect can not occur.
- the device should be characterized in that a simpler Prozeßpat- tion is possible and the required process parameters are more accurate and faster controllable.
- the heating means of the device have at least one independently operated heating element, which can be operated independently of other parts of the system with which the device interacts.
- the proposed heating element is not dependent on an energy supply from another part of the plant, the temperature of the supplied billet can be done much faster and more precise, so that the process is easier.
- the heating element may be a gas burner or an electrically operated element; In the latter case, above all, an induction heating element is suitable.
- the supply means may comprise a holding device for at least one ingot, with which the ingot can be held so that it at least partially immersed in the metal bath.
- the holding device is preferably equipped with movement means which it can move between a first position in which the ingot is located outside the metal bath and a second position in which the ingot is located at least partially inside the metal bath.
- the moving means of the holding device can be designed so that they can perform a combined lifting and tilting movement of the holding device.
- the heating means on the supply means are arranged to be movable.
- the heating means are arranged in the region of the supply means in the conveying direction in front of the metal bath stationary.
- the heating means may be arranged in the region of a part of the supply means, on which the ingot is conveyed in the horizontal direction.
- the device preferably has conveying means for preferably automatically conveying bars from a support or storage station to the holding device.
- the conveying means may have a Hubbalken user and / or a sliding mechanism.
- the conveying means can also feed two parallel bars holding devices.
- the proposed device it is possible to quickly and accurately preheat the temperature of the bar to be supplied to the metal bath to a desired temperature, so that optimal process control can take place. Preheating is done in a precise and economical way.
- FIG. 1 shows a perspective view of a zinc ingot charging device according to a first embodiment
- Fig. 2 in perspective view an alternative embodiment of the Zinkbarrenchargiervorraum.
- a device 1 for introducing zinc ingot 2 in a metal bath 3 is shown. From the metal bath 3 projects in a known manner, a furnace trunk 11, in which the metal strip to be coated (not shown) is guided. The feeding of ingot 2 into the metal bath 3 takes place with the feeding means 4 shown.
- a component of the feeding means 4 is a holding device 6, which holds the ingot 2 to be introduced into the metal bath 3 in such a way that it dips into the bath 3 to a desired degree and can thus melt off.
- An essential part of the device 1 is a heating means 5, which has a (not shown in detail) independently operated heating element, which can be operated independently of other parts of the system with which the device 1 cooperates.
- the heating element has its own energy supply, which is not coupled to other parts of the system. In particular, the heat of another furnace is not used to warm the bars 2.
- a heating element As a heating element, a gas burner or an electric heater can be used.
- an induction heater with which a quick heating of the billet 2 is possible, has proven to be useful.
- the heating means 5 are arranged to be movable. As can be seen in the synopsis of the two charging devices 1 of Fig. 1, the heating means 5 makes the (lifting and tilting) movement of the holding device 6 with. Thus, the ingot 2 can be kept exactly tempered until immersed in the metal bath 3. The heating means 5 are thus fixed mitbeweglich on the charging device. The billet 2 can be heated constantly and can also be tempered during the Abschmelzvorgangs itself.
- FIG. 2 Another possibility is shown in Fig. 2.
- the heating means 5 are arranged stationary, in the area over which the ingot 2 is guided horizontally on the feed means 4.
- the ingot 2 can be heated in a waiting position, while the previous ingot melts in the metal bath.
- the thus preheated billet 2 reduced when immersed in the metal bath, the temperature difference that he would cause without preheating.
- FIG. 1 an arrangement is shown in which two charging devices 1 are arranged laterally next to the furnace trunk 11.
- the left or rear Charging device dips just the metal bar 2 in the metal bath 3, so that it can melt.
- the right or front charging device 1 holds the bar 2 in a not yet dipping position.
- the holding device 6 can be moved between two positions, namely between a first position (right or front), in which the metal bar 2 is not yet immersed in the metal bath 3, and a second position (left or rear). in which the ingot 2 dips and melts.
- the holder of the billet 2 is effected by a basket element 10th
- the general handling of the ingot 2 can be seen from the further apparatus configuration according to the figures:
- the input of the zinc ingot 2 is carried out by a forklift at a support or storage station 9, which is located at the end of a lifting beam conveyor 7.
- the bars 2 are preferably abandoned from the operating side on the trained as a step conveyor Hubbalken makeuper 7.
- Hubbalken makeupers 7 By the conveying movement of Hubbalken makeers 7, the zinc ingot 2 are transported to the center of the plant.
- the zinc ingots 2 Once the zinc ingots 2 have arrived at the end of the lifting beam conveyor 7, they are transported on by an associated slide mechanism 8; the zinc ingot 2 is now pushed at a 90 ° angle to the supply conveyor 7 in the direction of the holding device 6.
- a transport surface is a transfer table 12 with a stainless steel plate over which the bar 2 is pushed.
- Between the conveyor 7 and the holding device 6 is still an intermediate position. This serves to bridge the distance between the conveyor 7 and the holding device 6 and as a store in the event of a supply bottleneck in the zinc ingot delivery.
- the stroke of the sliding mechanism 8 transports the bar 2 from the conveyor 7 to the intermediate position and at the same time the bar 2 from the intermediate position in or on the holding device 6.
- the holding device 6 lifts after loading with a bar 2 by not shown moving means the zinc ingot 2 from the transfer table 12 and tilts the bar 2 at the same time Direction metal bath 3.
- the zinc ingot 2 is supported on the basket element 10 from.
- the basket element 10 is immersed with the zinc ingot 2 in the liquid zinc in the metal bath 3.
