Definitions
- the invention relates to a method and a device for stripping excess metal melts, especially zinc melts Hot dip and takes the priority of German patent applications 100 61 869.3 and 101 28 710.0 claim to the content Reference is made.
- metal layers e.g. also zinc layers by means of different Process applied to metal strips. So goes through, for example the strip in hot dip galvanizing first a molten zinc and is then removed upwards. Due to its viscosity, the melt adheres above the metal bath level on the metal band and thus forms a around the metal band freely adhering zinc layer.
- This zinc layer is usually much thicker than needed - so it can partly up to 20 times the required layer thickness amount - and must therefore follow the respective target Layer thickness are returned.
- the excess metal is still in a liquid state outside the bath and above the metal bath level with the help of pneumatic Retain scrapers so that the desired layer thickness results.
- a gap nozzle installed across the entire bandwidth.
- the gas is e.g. Air or nitrogen is used. Due to the high impact impulse of the gas melt is stripped onto the liquid melt layer and flows on Band along back into the bathroom.
- the main disadvantage of this process is that zinc layers of 30 to 40 g / m 2 per strip side can be produced at most, although in some cases even thinner layers are required.
- the slit nozzles can become blocked if the strip hits the nozzles.
- Another disadvantage is that undesirable slag is formed when air is used. There are also problems with noise pollution and the generation of zinc dust.
- inductors with electrical coils are above arranged the melt. However, they can also partially melt plunge.
- the current applied in the coils creates a magnetic field that in turn induces a current in the molten zinc.
- excess Metal is first discharged upwards with the belt and is Magnetically stripped connection to it. The effect created in this way corresponds therefore in principle that of the pneumatic wipers.
- the known electromagnetic stripping processes require a very high magnetizing current and moreover have the particular disadvantage that layers of at least 90 g / m 2 can be produced.
- the invention is therefore based on the object of a method for Stripping of metal melts, in particular for producing thin metal layers To provide the disadvantages of the prior art largely overcomes. Likewise, a device for performing ' Procedure are provided.
- the inventive method is based on the idea that the removal of an object - for example a tape - starting downward melt flow into one of the upward movement accelerate opposite direction and the accelerated Melt flow in the form of a so-called free jet back against the belt to lead.
- the melt flows in countercurrent down to the ascending band. Through this countercurrent the Boundary layer, i.e. the metal layer on the belt is reduced.
- the method according to the invention therefore uses the kinetic energy of Flow for stripping off excess melt. Accordingly, it represents in Dynamic stripping compared to the known methods, while those are more static because there is no flow to the boundary layer, but only volume forces are shaped in the boundary layer.
- the Acceleration of the melt flow and the subsequent exploitation The kinetic energy has the advantage that it is essential allow higher energy densities to be achieved on the belt.
- the generation and acceleration of the melt stream can be done magnetohydrodynamically (magnethydrodynamic Scraper (MHD)).
- MHD magnetohydrodynamic Scraper
- a magnetic field and the Current impressed separately, but only impressed a magnetic field This induces the current in the melt. Act advantageously it is a magnetic rotating field.
- Magnetic hydrodynamic stripping is based on the following principle:
- Inductors can induce stresses in the molten metal and in the strip and thus generate an electric flow field. It can together with the resulting magnetic field, a force field in the metal bath, arise in the metal layer as well as in the band. The direction of force in The area between the inductors essentially points downwards and is opposite to the direction of the ascending band.
- the retention of the metal can thus largely below and above of the metal bath level, the preferred range for the Retention of the metal is at the level of the metal bath level. Play it several sub-processes a role, one below the bath level Circulating flow field in the molten metal directed below can arise, which - in the case of a narrow cross section - a may have increased speed.
- the method according to the invention can accelerate the melt flow in a flow gap (or flow channel) made between one to generate the Rotary field used inductor and a surrounding the inductor Housing lies.
- a flow gap or flow channel
- the melt stream enter the flow gap and then it with high circulation speed relative to the belt speed circulate before leaving the outlet of the gap at the level of the metal bath is fired.
- the Outlet be formed in the form of a slit nozzle.
- the use of a flow channel has the advantage that the melt comes into contact with the ambient air as little as possible and so unwanted slagging can be reduced. For example, if the stripping done on a belt, this arrangement on both sides of the Be attached tape.
- the angle between that from the flow gap against the melt flowing free jet and the belt as small as possible are kept, so that an unwanted vortex formation especially in the critical space, i.e. the space above the impact of the Free jet on the belt is avoided as far as possible.
- This so-called angle of attack is preferably less than 20 degrees.
- the stripping is advantageously carried out by means of the invention Procedure at the point of exit of the object from the molten metal.
- the stripping device can be entirely or partially immerse in the melt.
- the layer thickness of the metal layer remaining on the object varies become.
- the layer thickness can be influenced by a change in the flow angle of the free jet.
- the housing surrounding the inductor can be kept to a minimum and ceramic coated on the outside.
- the housing be ferromagnetic so that there is a magnetic yoke for the rotating field can form. This has the advantage of reducing what is required Magnetizing current.
- the housing can be several variable in the direction of the bandwidth Have additional air gaps in the form of movable segments through which the magnetic reflux can be changed specifically. This leads to an influence the flow rate of the melt at the discharge nozzle (Outlet), so that the thickness of the metal layer over the width of the Can set object.
- the layer thickness at individual width points can therefore about the strength of the magnetic field can be adjusted using the air gaps.
- the inductor preferably has a width that is greater than the respective Bandwidth is. It can be made from a laminated iron package with grooves for one electrical winding exist. According to the invention, the inductors be positioned either horizontally or vertically. The windings of the Inductors should be arranged so that a rotating one Magnetic field (rotating field) arises.
- the band gap can be a few millimeters. If the Consists of an iron package, this can be the so-called yoke represent for the inference of the molten metal.
- the object underlying the invention can also be achieved by a method be solved according to claim 9.
- This solution is based on the idea that the use of high-frequency periodic pressure changes at or near the exit point of the Subject of influencing the flow conditions at the boundary layer the melt can be reached on the belt.
- the pressure changes can in the melt itself or in the surrounding atmosphere be generated. In the latter case, the pressure changes can Continue melting.
- the viscosity of the melt to be changed.
- This so-called dynamic viscosity is in addition to Speed and weight as well as dependent on it Reynold number an essential parameter that depends on the flow conditions in the boundary layer, i.e. for example whether the flow is laminar or is turbulent.
- the method according to the invention are at least at the exit height of the object from the melt two sides several powerful ultrasound transmitters, for example Piezo transmitter attached.
- the transmitters can be partially or completely submerged. You can in a hollow beam must be installed so that it is protected against the melt are. The distance between the transmitter heads and the object can only be a few millimeters be.
- a transversal Pressure wave arise perpendicular to the band, which reflects on the object becomes. Due to the periodic high frequency pressure changes then the viscosity of the melt, especially in the case of cavitation. This reduces the effective viscosity, so that the thickness of the Metal layer can be reduced.
- the arrangement 1 of Fig. 1 consists of two inductors 2 and 3, some of which Immerse in a bath 4 made of molten zinc 5. You are at a height h2 arranged above the bath level.
- the windings of the inductors are arranged such that a rotating one Magnetic field 7 (rotating field) arises, whose direction of force is the direction of travel of the ascending band is opposite.
- the winding 2 consists of a cylindrical ferromagnetic inductor 10, the surface of which is ceramic-coated is. It has a multi-phase winding 20 that extends over its entire length Scope is distributed. The winding receives impressed currents with adjustable Amperage and frequency. The winding creates a rotating magnetic field.
- the inductor is made of an equally cylindrical ferromagnetic Surround housing 30, which is coated on the inside and outside ceramic. It carries radially displaceable housing segments 40 for setting one Additional air gap I.
- a flow gap 50 runs through the housing and the inductor, through which liquid metal melt runs at a high rotational speed relative to the speed V B of the strip.
- the current flows counterclockwise in the picture.
- the flow gap is opened towards the belt via an outlet 60 and an inlet 70.
- the inlet is located close to the belt below the outlet.
- Inlet and outlet have an angle ⁇ E and ⁇ A to the bath mirror 90.
- the free jet 110 emerges from the outlet. It meets the upwardly moving band 80 at the inflow angle and at the outflow velocity V.
