Definitions

  • the invention relates to a process 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, wherein for retaining the coating metal in the container in the region of the guide channel an electromagnetic field by means of at least two inductors arranged on either side of the metal strand are produced, and wherein for stabilizing the metal strand in a central position in the guide channel, an electromagnetic field superimposed on the electromagnetic field of the inductors is generated by means of at least two additional coils arranged on both sides of the metal strand. Furthermore, the invention relates to a device for hot dip coating of a metal strand.
  • the tapes are introduced into a dip proboscis from above into the dip coating bath. 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 band contact until complete solidification of the coating metal, the band must be deflected in the coating vessel in the vertical direction. 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.
  • non-ferromagnetic metal bands are thus possible, but problems occur in the substantially ferromagnetic Stahlbändem that they are drawn in the electromagnetic seals by the ferromagnetism to the channel walls and the tape surface is damaged. Furthermore, it is problematic that the coating metal and the metal strip itself are inadmissibly heated by the inductive fields.
  • the position of the passing ferromagnetic steel strip through the guide channel between two traveling field inductors is an unstable equilibrium. Only in the middle of the guide channel is the sum of the magnetic forces of attraction acting on the tape zero. As soon as the steel strip is deflected from its center position, it gets closer to one of the two inductors, while it moves away from the other inductor. Causes of such a deflection may be simple flatness errors of the tape.
  • any kind of tape waves in running direction seen across the width of the tape (Centerbuckles, Quarterbuckles, Randwellen, Flattem, twisting, Crossbow, S-shape, etc.).
  • the magnetic induction which is responsible for the magnetic attraction decreases according to an exponential function with the distance from the inductor in their field strength.
  • the attraction force decreases with the square of the induction field strength with increasing distance from the inductor. For the deflected band, this means that with the deflection in one direction, the attractive force to one inductor expands exponentially, while the restoring force from the other inductor exponentially decreases. Both effects are self-reinforcing, so the balance is unstable.
  • JP 05078802 A A similar concept is also disclosed in JP 05078802 A.
  • the additional coils are positioned in the guide channel below the inductors.
  • the invention is therefore based on the object to provide a method and an associated apparatus for hot dip coating of a metal strand, with which or with which it is possible to overcome the disadvantages mentioned.
  • the efficiency of the control should therefore be improved, which should make it possible in a simpler manner, to keep the metal strand in the middle of the guide channel.
  • the concept of the invention is based on the fact that the three sizes of position of the metal strand in the guide channel, induction current in the inductors and induction current in the auxiliary coils are detected and taken into account in the regulation of the position of the metal strand; the manipulated variable of the control loop is then in turn the induction current in the additional coils.
  • the electromagnetic field generated for sealing is a multi-phase traveling field, which is generated by applying an alternating current with a frequency between 2 Hz and 2 kHz.
  • a single-phase alternating field can be provided, which is generated by applying an alternating current with a frequency between 2 kHz and 10 kHz.
  • the determination of the position of the Metatlstranges in the guide channel is made inductively.
  • the measuring means (the measuring coils) for determining the position of the metal strand thus lies within or outside the range of the electromagnetic elements, by which both the inductor and the additional coils are to be understood.
  • the measuring device prefferably be arranged in front of the additional coil in the region of the extension of the inductor, for the measuring device to be arranged in the region of the extension of the inductor next to the additional coil, or for the measuring device to be arranged outside the region of the extent of the inductor. Combinations of these arrangements are possible.
  • the device according to the invention for hot dip coating a metal strand 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 and with at least two arranged on both sides of the metal strand auxiliary coils for generating a the electromagnetic field of the inductors superimposed electromagnetic Field for stabilizing the metal strand in a central position in the guide channel is characterized by measuring means for measuring the position of the metal strand in the guide channel, the induction current in the inductors and the induction current in the auxiliary coils and by control means for controlling the induction current in the auxiliary coils in dependence measured parameters are suitable to hold the metal strand in a central position in the guide channel, the auxiliary coils in deliberatelyrichtun g of the metal strand seen within the extension of the inductors are arranged.
  • the measuring means for detecting the position of the metal strand in the guide channel is an inductive sensor.
  • the measuring means for detecting the position of the metal strand in the guide channel in the conveying direction of the metal strand is arranged within the extension of the inductors. But it is also possible that the measuring means is arranged outside the extension of the inductors. In both cases, it is possible that the measuring means for detecting the position of the metal strand in the guide channel in the conveying direction of the metal strand is arranged outside the extension of the additional coils. This ensures a precise position detection of the metal strand.
  • a development provides that several measuring means are arranged for detecting the position of the metal strand in the guide channel at different points in the conveying direction of the metal strand.
  • the individual measuring means can be arranged both inside and outside the magnetic fields of inductor or additional coil.
  • FIG. 1 An embodiment of the invention is shown.
  • the single figure shows schematically a hot-dip coating device with a guided through this metal strand.
  • 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 an exaggeratedly large or broad guide channel. 4
  • the molten coating metal 2 can not flow down through the guide channel 4 down, are located on both sides of the metal strand 1, two electromagnetic inductors 5, which generate a magnetic field, which causes buoyancy forces in the liquid coating metal 2, which counteract the gravitational force of the coating metal 2 and thus seal 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.
  • the aim is to keep the metal strand 1 located in the guide channel 4 so that it is defined as possible in a position, preferably in the center plane 11 of the guide channel 4, is located.
  • the metal strand 1 located between the two opposing inductors 5 is generally attracted to the closer inductor upon application of an electromagnetic field between the inductors 5, the attraction increasing as it approaches an inductor, resulting in a highly unstable midband position. This results in the operation of the device, the problem that the metal strand 1 due to the attraction of the inductors 5 can not run freely and centrally through the guide channel 4 between the activated inductors.
  • additional coils 6 are arranged on both sides of the guide channel 4 and der Metallstranges 1. These are controlled by a control means 10 so that the superposition of the magnetic fields of the inductors 5 and the additional coils 6 keeps the metal strand 1 always in the middle in the guide channel 4.
  • the magnetic field of the inductors 5 can be amplified or attenuated depending on the control (superposition principle), without violating the sealing condition (minimum required field strength for the seal). In this way, the position of the metal strand 1 in the guide channel 4 can be influenced.
  • control means 10 are initially supplied with a signal s, s' or s "representing the position of the metal strand 1 in the guide channel 4.
  • the position s, s' or s" is determined by position measuring means 7, 7 'and 7, respectively.
  • the determination of the position of the metal strand 1 between the inductors 5 in the electromagnetic field thus takes place inductively, the feedback effect of the metal strand 1 in the magnetic field being utilized.
  • the control means 10 are further supplied with the determined by current measuring means 8 and 9 induction currents in the inductors 5 - current I Ind - or in the auxiliary coils 6 - current I Korr -vermony.
  • Algorithms are stored in the control means 10, which, starting from the three parameters position s, s' or s "of the metal strand 1 in the guide channel, induction current I Ind in the inductors 5 and induction current I Korr in the auxiliary coils 6, a new control signal in the form of an induction current I Korr to the auxiliary coils 6.
  • the position of the metal strand 1 in the closed loop is maintained so that the positional deviations of the metal strand 1 from the center plane 11 are minimal, ie that the value s, s' or s "zero possible becomes.
  • the position s, s 'or s "of the metal strand 1 in the guide channel 4 by means of the position measuring means 7, 7' and 7" determined, the position measuring means 7 - viewed in-conveying direction R - above the inductors , the position measuring means 7 'are positioned below the inductors 5 and the position measuring means 7 "in the area of the inductors 5.
  • all three position measuring means 7, 7' and 7" are arranged outside the range of the additional coils 6. From the means the position measuring means 7, 7 ', 7 "measured values, an average value can be formed in the control means 10.
  • the position measuring means 7, 7 'and 7 are inductive displacement transducers, the influence of the magnetic fields which are caused by the inductors 5 and the additional coils 6 should remain as small as possible. This is achieved by the arrangement of the position measuring means 7 7 'outside the extension of the inductors 5. However, as can be seen in the figure, a position measuring means (in the present case 7 ”) can be positioned in the region of the inductors 5.
