Definitions

  • the invention relates to a device for hot dip coating a metal strand, in particular a steel strip, in which the metal strand is passed vertically through a container receiving the molten coating metal and through an upstream guide channel, with at least two on both sides of the metal strand in the region of the guide channel arranged inductors for generating an electromagnetic Field for retaining the coating metal in the container.
  • the belts are introduced from above into the dip-coating bath in a plunger. Since the coating metal is in liquid form and one would like to use the gravitation together with blowers for adjusting the coating thickness, but the subsequent processes prohibit belt contact until complete solidification of the coating metal, the tape in the coating vessel in vertical Direction be redirected. This happens with a roller that runs in liquid metal. Due to the liquid coating metal, this roller is subject to heavy wear and is the cause of downtimes and thus failures in production.
  • EP 0 630 421 B1 provides for a constriction below the guide channel, from which a pipeline leads to a reservoir for molten coating metal. Further details on the design of this designated as a backstop device are not apparent from this document.
  • JP 2000273602 A discloses below the guide channel a collecting trough, which is to receive coating metal, which runs down through the guide channel. This is led to a container, from where it is returned to the coating bath via a pump. Again, no specific and specific information is given as discontinued coating metal to be collected.
  • EP 0 855 450 B1 deals in more detail with the question of how the tightness of the lower region of the guide channel can be ensured.
  • various alternative solutions are disclosed here.
  • two slides which are arranged on both sides of the metal strand, are moved perpendicular thereto to the surface of the metal strand.
  • the sliders act as stoppers and are held in contact with the metal strand as needed to prevent liquid leakage down the guide channel.
  • a relatively complex control of the slide is required to ensure its function.
  • Another embodiment provides that a conveyor belt is used, which promotes exiting coating metal from the area below the guide channel into a collecting container.
  • this solution is very expensive and involves the risk that the band clogged with coating metal over time and thus can no longer perform its function.
  • a third alternative solution for preventing the escape of molten coating metal provides a gas nozzle system.
  • a gas flow is directed from below onto the guide channel, the emerging coating metal tear up and thus seal the opening down.
  • a hot-dip coating installation is known in which it is provided that a barrier is arranged in the bottom area of the coating vessel at the transition into the guide channel. This is to keep the flow in the liquid coating channel from the guide channel; For this purpose, it is provided that it is equipped with aerodynamically designed walls or baffles.
  • the barrier disclosed in this document is not suitable for keeping the liquid coating metal from the region of the guide channel if necessary. In the same way, it is not possible for him to influence the coating process.
  • the invention is therefore based on the object to provide a device for hot dip coating of a metal strand, with which it is possible to perform the coating process optimally and also to ensure reliable operation of the system in critical operating conditions in a simple manner, for example, interrupted when the power supply of the inductors is.
  • the solution of this object by the invention is characterized by a above the guide channel in the bottom region of the container arranged closure means for selectively enabling or interrupting the flow of molten coating metal to the metal strand and / or the guide channel, wherein the closure means is designed as weir, relative to the bottom portion of the Container is movable.
  • the flow of the coating metal in particular, can optionally be released or interrupted, in particular in the case of a malfunction, so that there is no danger of molten metal leaving the coating device via the guide channel.
  • the weir has two cooperating parts which are each movable perpendicular to the surface of the metal strand.
  • the weir is movable in the conveying direction of the metal strand.
  • the weir is formed in one piece and has the shape of a box. In this way, both the production of the weir can be done inexpensively and the operation of the device can be ensured in a particularly simple manner.
  • the weir has cover means in its upper end region facing away from the bottom region of the container.
  • the coating bath in which turbulences are introduced by the electromagnetic excitation by the inductors, calms down.
  • the covering means are designed as wall sections which extend parallel to the bottom region of the container.
  • cover means are formed as a plate having a gap-shaped recess for the passage of the metal strand.
  • the closure means in particular the weir, preferably communicate with manual, pneumatic or hydraulic actuating means; the actuating means may be associated with a plant controller which causes the flow of molten coating metal to release or interrupt the flow of metal to the metal strand and / or guide channel.
  • FIG. 1 schematically shows a hot-dip coating device with a metal strand 1 guided through it.
  • the device has a container 3 which is filled with molten coating metal 2.
  • molten coating metal 2 This may be, for example, zinc or aluminum.
  • To be coated metal strand 1 in the form of a steel strip passes through the container 3 in the conveying direction R vertically upwards. It should be noted at this point that it is also possible in principle that the metal strand 1, the container 3 passes from top to bottom. For the passage of the metal strand 1 through the container 3, this is open in the bottom area; Here is a guide channel. 4
  • the molten coating metal 2 can not flow down through the guide channel 4, located on both sides of the metal strand 1, two electromagnetic inductors 5, which generate a magnetic field, which counteracts the gravitational force of the coating metal 2 and thus seals the guide channel 4 downwards.
  • the inductors 5 are two oppositely disposed alternating field or traveling field inductors, which are operated in the frequency range from 2 Hz to 10 kHz and establish an electromagnetic transverse field perpendicular to the conveying direction R.
  • the preferred frequency range for single-phase systems (AC field inductors) is between 2 kHz and 10 kHz, that for multi-phase systems (eg traveling field inductors) between 2 Hz and 2 kHz.
  • a closure means 7 or 7 'designed in two parts as an embodiment according to FIG. 1 is arranged in the form of a weir.
  • the two parts 7, 7 'of the weir are movable parallel to the bottom of the container 3 in the direction of the double arrow.
  • a movement actuation means 11 are provided, which are illustrated here only schematically as piston-cylinder units; just as any other type of actuator can be used.
  • the weir 7 or 7 ' is presently designed as a divided into two parts box, the two halves 7 and 7' can cooperate so that they seal the region of the guide channel 4 in the bottom portion 6 of the container 3. This situation is sketched in FIG. Consequently, the coating metal 2 can not penetrate to the guide channel 4 or to the metal strand 1.
  • This closed position of the weir 7 or 7 ' is particularly important for two operating cases:
  • this position is taken before the coating system is started up.
  • the metal strand 1 then moves - without that coating metal 2 can approach it - in the conveying direction R up, and the inductors 5 are activated. Only then are the two weir parts 7 or 7 'moved in the direction of the double arrow away from the metal strand 1, so that coating metal 2 can penetrate to the metal strand 1 and into the region of the guide channel 4 through the box opening thereby. Since the inductors 5 are activated, there is no escape of coating metal 2 down through the guide channel 4.
  • the weir 7, 7 'thus encloses first the downwardly open guide channel 4 and thus the passing through this metal strand 1 to an optimized height the bottom portion 6 of the container 3, so that no coating metal 2 can flow in the direction of the guide channel 4. With the start of the coating process, the weir 7, 7 'is then opened, so that the coating metal 2 to the metal strand 1 and thus in the guide channel 4, which is now electromagnetically sealed by the inductors 5, can flow in time and volume optimized.
  • the weir 7, 7 'then has meaning, if there is a power failure and the inductors 5 (eg until the start of an emergency generator) can no longer perform their task, namely the guide channel 4 down through the built-up to seal electromagnetic field.
  • Fig. 2 the weir 7, 7 'again outlined in a perspective view, in the closed state.
  • the double arrows indicate in which direction with respect to the conveying direction R of the metal strand 1, the two weir parts 7, 7 'can be moved, including the actuating means 11, s. Fig. 1, serve. It can be seen that in the bottom area of the weir 7, 7 'a Passage opening for the metal strand 1 is present; in the illustrated closed position of the weir 7, 7 'is nevertheless ensured that no coating metal 2 can enter the metal strand 1 and the guide channel 4.
  • FIG. 7 shows that the weir 7 can also be formed in one piece.
  • the box-shaped weir 7 then sets in the state in which it is closed, on the bottom 6 of the container 3 and thus seals the guide channel 4 from.
  • cover means 9 are provided in the end region 8 of the weir 7, 7 ', with which care is taken that the currents generated by the inductors 5 do not continue to spread in the direction of the bathroom surface.
  • the turbulence caused by the electromagnetic seal in the guide channel 4 or in the container 3 of the liquid coating metal 2 can thus be kept away by the design of the weir 7, 7 'and in particular by the cover 9.
  • the weir 7 is integrally formed, the following is shown in Fig. 5 shown possibility:
  • the weir 7 is provided with a recess 10 in the upper region, which allows passage of the metal strand 1.
  • the currents generated in the coating metal 2 by the inductors 5 are here by the covering means 9, which here almost a complete encapsulation of the inner region of the weir 7 to the rest of the coating bath held held. With this configuration, it is possible to optimally calm the bath surface and thus ensure a high-quality coating.
