Definitions

  • the invention relates to a process for the hot dip coating of 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 a preceding guide channel of defined height, wherein for the retention of the coating metal in the container in the region of the guide channel an electromagnetic field is produced by means of at least two inductors arranged on both sides of the metal strand, wherein a predetermined volume flow of coating metal is supplied to the guide channel in the region of its vertical extent. Furthermore, the invention relates to a device for hot dip coating of a metal strand.
  • the belts are immersed in a dip-tube from above into the dip-coating bath introduced. 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.
  • a generic method is also described in EP 0 630 421 B1, in which it is furthermore provided that the coating container accommodating the coating metal is assigned a premelting container which is larger in volume by a multiple than the coating container.
  • the coating container is supplied with coating metal from the pre-melt container when it is discharged from the coating container through the coated metal strand.
  • a hot-dip coating method is known in which melt is removed from the container via a channel extending downwards from the coating container and, after being diverted into the vertical in the region of the guide channel, is supplied thereto.
  • a coating process without the use of electromagnetic inductors is known from JP 63 192853 A. There is provided by means of two pairs of rollers for a closure of a guide channel for the vertical passage of the metal strand to be coated. In the channel melt is entered.
  • the electromagnetic closure used in the above-discussed solutions for sealing the guide channel thus constitutes a magnetic pump which retains the coating metal in the coating container.
  • the invention is therefore based on the object to provide a method and associated apparatus for hot dip coating of a metal strand, with which or with which it is possible to overcome the mentioned disadvantage. It should therefore be ensured that the immersion bath remains quiet when using an electromagnetic shutter, whereby the quality of the coating should be increased.
  • the solution of this object by the invention according to the method is characterized in that the predetermined volume flow coating metal, which is supplied to the guide channel, a part of the required to maintain a desired level height of the coating metal in the container Vietnamesevolumens coating metal per time corresponds.
  • the predetermined volume flow corresponds to the total metal tracking volume required to maintain the level per time.
  • the electromagnet pump performing a seal to seal the guide channel is no longer quasi idle, but receives a volume flow coating metal supplied and promotes.
  • the surprising result is that on the surface of the metal bath, a calming of the bath occurs, which has a very positive influence on the quality of the hot-dip coating.
  • the container in which the coating metal is located with a supply system (supply tank) for coating metal communicates.
  • supply tank supply tank
  • From the supply tank of the bulk discharge is nachge redesignt into the container, which is required to maintain a constant level level in the container, since the metal strand promotes coating metal in its promotion by the coating system from the container.
  • the volume flow coating metal is supplied to the guide channel in a controlled or regulated manner.
  • the apparatus for hot dip coating a metal strand in which the metal strand is passed vertically through the container receiving the molten coating metal and through the upstream guide channel has at least two inductors arranged on both sides of the metal strand in the region of the guide channel for generating an electromagnetic field for retaining the coating metal in the container on. Furthermore, at least one supply line for supplying a predetermined volume flow coating metal is provided, which opens in the region of the vertical extent of the guide channel in this.
  • the device is provided in such a way that the supply lines open into the region of the longitudinal side and into the region of the end face of the guide channel.
  • the width or the diameter of the supply line in relation to the dimension of the longitudinal side of the guide channel is small; this means in particular that the width or the diameter of the supply line is at most 10% of the width of the longitudinal side of the guide channel.
  • the coating container to be connected to a coating metal supply system, from which coating metal is conducted into the supply line or into the supply lines.
  • the device shown in the figures 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.
  • 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.
  • correction coils 13 are further arranged on both sides of the guide channel 4 and der Metallstranges 1. These are controlled by - not shown - control means so that the superposition of the magnetic fields of the inductors 5 and the correction coils 13 keeps the metal strand 1 always in the center of the guide channel 4.
  • the magnetic field of the inductors 5 can be amplified or attenuated depending on the control (superposition principle of the magnetic fields). In this way, the position of the metal strand 1 in the guide channel 4 can be influenced.
  • a supply system 12 supply tank
  • an inlet 16 is supplied.
  • a predetermined volume flow Q coating metal 2 is supplied to the guide channel 4 in the region of its height extension H.
  • two supply lines 6 and 7 in the region of the necessary for the passage of the metal strand 1 passage gap in the guide channel 4, in the region whose height extension H.
  • the width B of the supply lines namely in the region of their exit into the guide channel 4, is small in relation to the width of the longitudinal side 11 of the guide channel 4.
  • the supply lines 6, 7, 8 and 9 are thereby supplied with coating metal 2 by a pump 14 schematically sketched in FIG.
  • the volume flow Q supplied by the pump 14 can make up a part of the volume flow of coating metal which has to be supplied to the bath for maintaining the level height h.
  • the entire amount of coating metal 2 necessary for this purpose is supplied via the pump 14 per time, so that in this case no further pumping takes place via the pump 15.
  • first coating metal 2 is filled into the container 3 and after activating the inductors 5 the tape run is started.
  • a volume flow Q of coating metal is supplied via the supply lines 6, 7, 8 or 9 to the guide channel 4.
