Definitions
- the invention relates to a method for strip stabilization in a system for coating strip-shaped material, in which a metal strip is passed through a container which holds the molten coating material and which has a passage channel below the molten pool level, in which induction currents are induced in the coating material by an electromagnetic traveling field. which, in interaction with the traveling electromagnetic field, produce an electromagnetic force for holding back the coating material.
- the present invention has for its object to find a method and an apparatus for stabilizing the tape in a generic system, with which the tape material in a more or without contact from the outside less symmetrical position is brought so that it does not come into contact with the walls of the coating channel and is damaged.
- the stabilization should be adaptable to different bandwidths, belt thicknesses and material qualities.
- a controllable magnetic field superimposed on the modulation of the electromagnetic traveling field is applied in the area of the feed-through channel, the field strength and / or frequency of which can be set as a function of the sensor-detected strip position in the coating channel.
- the adjustable magnetic field makes it possible to guide the tape in the feed-through channel in such a way that it is introduced into the coating material without touching the walls and without vibrations. There is no need for mechanical guides.
- control of the magnetic field be carried out as a function of the sensor-detected strip position in the coating channel.
- the magnetic field is amplified or weakened or changed on one side so that the tape runs accordingly.
- Another solution is to share the coils for the traveling field for sealing and for band stabilization.
- the control of the coil pair (s) is carried out via thyristors, which are controlled to the extent that a secure seal is achieved.
- thyristors which are controlled to the extent that a secure seal is achieved.
- a device for band stabilization in a generic system is characterized by several on both sides of the band in the area of Coating channel arranged individually switchable or disconnectable magnet coil pairs, the field strength and / or frequency is adjustable.
- the magnetic coils can be arranged, for example, between the coils of the electromagnetic traveling field and the bottom opening of the container on both sides of the band and can be dimensioned according to the width of the band.
- the magnetic coils can be switched on or off individually, the magnetic field can be influenced more sensitively or the magnetic field can be adapted to different bandwidths.
- FIG. 1 shows a roughly schematic representation of a container 1 for molten coating material 2, with a bottom-side opening 3, which continues in a through-channel 4 for the band 5 running vertically through the container 1.
- Coils 6, 7 are arranged around the feed-through channel 4, in which a Electromagnetic traveling field is induced, which causes an electromagnetic force to retain the coating material 2.
- additional magnetic coils 8, 9 and / or 10, 11 are provided on both sides of the band 5 and the feed-through channel 4, which, as shown schematically in FIG 8.9 recognizable, extend over the entire width of the band 5.
- the magnetic coils 8, 9 and 10, 11 can be controlled according to the invention with regard to field strength and / or frequency in order to be able to adapt to different strip materials or strip thicknesses.
- the magnetic coils 8a, 8b, 9a, 9b can be arranged at a distance from one another and aligned with the edge regions of the band 5 and can be displaced in both directions parallel to the band surface.
- the shift can take place hydraulically, pneumatically or by electric motor.
- 4 magnetic coils 8a, 8b, 8c, 8d, 9a, 9b, 9c, 9d are provided on both sides of the band 5, of which, depending on the bandwidth, the outer coils 8a, 9a, 8d, 9d and can be switched off.
- the coils can be divided into one coil above and one below the inductors.
- 4 sensors can be arranged on the belt 5, for example below the feed-through channel, which sensors correspond to the incoming belt 5 in the form of field strength sensors or belt position sensors.
- the tape position detected by the sensors is processed in a computing unit into a signal with which the magnetic coils are controlled.
