Definitions
- the present invention relates to the technical field of galvanizing iron-based or iron-containing components, in particular steel-based or steel-containing components (steel components), preferably for the automotive or automotive industry, by means of hot dip galvanizing (hot-dip galvanizing).
- the so-called fluxing takes place, the previously defatted and pickled steel surface containing a so-called flux, which is typically an aqueous solution of inorganic chlorides, most often mixed with a mixture of zinc chloride (ZnCl 2 ) and ammonium chloride (NH 4 Cl ).
- a so-called flux typically an aqueous solution of inorganic chlorides, most often mixed with a mixture of zinc chloride (ZnCl 2 ) and ammonium chloride (NH 4 Cl ).
- the flux increases the wettability between the steel surface and the molten zinc.
- drying is usually carried out to produce a solid flux film on the steel surface and to remove adhering water so as to subsequently avoid undesirable reactions (especially the formation of water vapor) in the liquid zinc immersion bath.
- the spray application results in an improved flow behavior of the applied flux due to the defined amount of spray agent applied.
- a sticking of a concentrated solution of the flux at the aforementioned corners and edges can be avoided, but in any case can be reduced. Due to the reduced and in particular uniform application of the flux compared to a dip coating, ultimately no superfluous flux is introduced into the galvanizing bath.
- the distance between the components of the small group attached to the carrier should be at least 10 cm, preferably at least 50 cm and in particular more than 1 m from each other.
- a separation of the component is present within the meaning of the present invention, since with such a distance of the components separated from one another, the accessibility to any area of the components for the automated Spray application is guaranteed.
- the drying device is preferably followed by a drying device.
- This drying device is designed in particular for drying the sprayed-on flux in the separated state of the component. Since a precisely defined application amount of flux is applied to the component by the spray application, the drying step can be carried out relatively quickly and thus relatively inexpensively, which is not possible in comparison with drying after a dipping bath.
- the separating means is designed such that a separated component is immersed in a dip area of the bath, then moved from the immersion area to an adjacent immersion area and subsequently immersed in the replacement area.
- the aforementioned movement can be achieved even when not working with a separating means, but instead the component is fastened in the separated state to the goods carrier and fed to the galvanizing bath via the goods carrier, immersed in the immersion region, moved to the immersion region and immersed there becomes.
- zinc ash is produced on the surface of the immersion area as a reaction product of the flux with the molten zinc.
- the invention provides plant and process according to the United tion during hot dip galvanizing the advantage that zinc noses can be easily avoided.
- a stripping device is provided following the immersion region, wherein in a preferred embodiment of this inventive concept, the conveying device or the separating means is designed such that all components are guided past the stripping device for stripping liquid zinc in an identical manner after emptying.
- the separating means which can also be realized in combination with the stripping device, it is provided that all components are moved in an identical manner after the immersion so that dripping noses of liquid zinc are removed, in particular drip off and / or evenly distributed on the component surfaces.
- the invention makes it possible to guide each individual component not only through the galvanizing bath, but also either in a specific positioning, for example an inclination of the component, and move past one or more scrapers and / or the component by special Rotary and / or steering movements to move after the immersion so that zinc noses are at least substantially avoided.
- a cooling device in particular a quenching device, is provided following the hot-dip galvanizing device, at which point the component is cooled or quenched after hot-dip galvanizing.
- a post-treatment device can be provided in particular following the cooling device.
- the aftertreatment device is used in particular for a passivation, sealing or coloring of the galvanized components.
- the post-treatment stage may also include, for example, the post-processing, in particular the removal of impurities and / or the removal of zinc noses. As has been stated above, however, the post-processing step in the invention is considerably reduced and sometimes even unnecessary in comparison with the method known in the prior art.
- control device is coupled not only with the individual spraying devices but also with the conveying device. This makes it possible, if necessary, to change the transport speed of the individual goods carriers. For example, it is possible to change the transport speed of a goods carrier at least in regions relative to the transport speed of another goods carrier. This makes it possible to adapt certain process steps, which take more time than others, as needed to the respective requirements. As a result, the entire process sequence of the method according to the invention is optimized and thus shortened.
