Definitions
- the invention relates to a method for strip stabilization in a plant for Coating of strip-like material, in which a metal strip through the melted coating material receiving container is passed through the has a through channel below the melt pool level, in which through a electromagnetic generated by means of a pair of coils or pairs of coils Wanderfeld in the coating material induced induction currents in Interaction with the traveling electromagnetic field an electromagnetic Cause force to retain the coating material, and wherein to Belt stabilization in the area of the feed-through channel additionally a controllable one Magnetic field is applied
- JP-A-6-136 502 is a Method for controlling the coating weight of a belt known, wherein the amplitude of the vibration and torsion through suitably arranged coil pairs of the vertical belt is to be reduced.
- the object of the present invention a method for Stabilize the tape with which to find the tape material without touching it outside in a more or less symmetrical position so that it does not come with comes into contact with the walls of the coating channel and is thereby damaged becomes.
- the stabilization should be at different bandwidths, band thicknesses and Material qualities to be adaptable.
- the solution lies in the shared use of the coils for the traveling field Sealing and for band stabilization.
- the modulation of the or of the coil pairs performed on thyristors, which are driven so far that a secure seal is achieved.
- a device for band stabilization in a generic system is characterized by a plurality of magnet coil pairs which can be switched on or off and are arranged on both sides of the band in the region of the coating channel and whose field strength and / or frequency can be adjusted.
- 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.
- At least individual magnetic coils are provided parallel to the Belt surface slidable to target specific areas of the Influencing the belt surface and adjusting to different belt widths to make.
- Figure 1 shows a rough schematic representation of a container 1 for molten Cover material 2, with a bottom opening 3, which is in a Feed-through channel 4 continues for the band 5 running vertically through the container 1.
- coils 6,7 are arranged, in which a electromagnetic traveling field is induced, which is an electromagnetic force to retain the coating material 2.
- additional magnetic coils 8, 9 and / or 10, 11 on both sides of the Band 5 and the feed-through channel 4 are provided, which, as in Figure 2 schematically in a cross section through the band 5 at the height of the magnet coils 8.9 extend over the entire width of the belt 5.
- Solenoid coils 8, 9 and 10, 11 are controllable according to the invention with respect to field strength and / or frequency in order to Adapt to different strip materials or strip thicknesses can.
- two or more magnetic coils are also conceivable 8a, 8b, 9a, 9b to be provided on both sides of the belt 5, which can be controlled individually in order to an even better influence on the band 5 in the magnetic field according to the invention to provide for stabilization.
- the solenoids 8a, 8b, 9a, 9b can be spaced to each other and to be aligned with the edge regions of the band 5 and be displaceable parallel to the belt surface in both directions. Thereby can be precisely adapted to the respective bandwidth of the band passing through 5 can be made.
- the displacement can be hydraulic, pneumatic or done by electric motor.
- FIG. 5 there are 4 magnetic coils on each side of the band 5 8a, 8b, 8c, 8d, 9a, 9b, 9c, 9d provided, of which, depending on the bandwidth, the outer Coils 8a, 9a, 8d, 9d can be switched on and off.
- the coils can be divided into one coil each above and below the inductors.
- the Through duct 4 sensors can be arranged in the form of field strength sensors or tape position sensors correspond to the incoming tape 5.
- the one from the The position of the tape detected by sensors is processed into a signal in an arithmetic unit, with which the solenoids are controlled.
