Definitions

  • the invention relates to a device for coating the surface of steel strip with a metallic coating, in which the material is passed without a reversal of direction through a container which holds the molten coating material and which has a passage channel enclosed by an electric field below the molten pool level, in the opening region of which in the opening region Melt generates an electromagnetic force of equal or greater magnitude proportional to the product of the cross-sectional area of the inlet opening and the metallostatic pressure, vectorially opposed to the metallostatic pressure, and in which the length of stay of the strip in the melt can be controlled independently of the throughput speed of the strip.
  • Plants for coating the surface of strip material are known as so-called hot-dip galvanizing or dip-coating coatings, in which the strip to be coated is introduced obliquely under protective gas from above into the container holding the coating medium and is deflected around a deflection roller within the weld pool.
  • the diverted good usually leaves the molten bath container in a vertical direction by means of suitable devices, where the coating material, for example zinc, adhering to the strip surface is adjusted and evened out in thickness.
  • Such devices e.g. B. in the form of nozzle knives, hold back excess coating material, so that a uniformly thick smooth surface is generated.
  • the known systems have disadvantages.
  • the belt deflection in the melted coating material can lead to unstable belt running and slipping of the belt on the roll and impair the quality of the coated belt.
  • the roller journals and bearings stored in the bathroom wear out quickly and have to be changed frequently, which always leads to downtimes of the entire system.
  • the wear of the pins and bearings can lead to vibrations of the belt and to a change in the distance between the belt and stripping nozzles, which adversely affects the uniformity of the coating over the belt length and width.
  • the deflection of the belt within the container requires a container with a large volume with a correspondingly large amount of coating material. On the one hand, this makes it very difficult to control the dwell time of the strip in the bath, and on the other hand, filling and emptying the container to change the coating material is very time-consuming.
  • Plants for coating strand-like material are also known, in which the material is passed through the molten coating material in a horizontal or vertical direction (FR-A 22 29 782 and EP-B1-00 60 225).
  • Systems of this type in which the strand-like material to be coated is passed through or into the molten coating material in areas below the surface of the molten bath, require corresponding seals which prevent the coating material from leaking out of the coating container.
  • the device described there consists of a container filled with molten coating material with a bottom through opening for the material to be coated, which is sealed by an electromagnetic pump.
  • an immersion body immersed in the molten coating material which also interacts with an electromagnetic pump, the effective height of the molten coating material is regulated and thus the contact time of the continuous strand-like material with the molten coating material is set.
  • the electromagnetic pump immersed in the melt with the immersion body is intended to prevent contact of the surface of the strand-like material to be coated with heavily soiled oxides. Even with short contact with the melt, a qualitatively perfect coating was achieved.
  • the contact time, the intensity of the contact and the temperature of the material to be coated and the molten coating material also determine the formation and the thickness of the intermetallic intermediate layer formed. This is of great importance for the layer adhesion and the layer quality, especially the formability of the coating.
  • the known institutions do not take this into account. Thus, it is not possible with prior art systems to influence the formation of the intermediate layer by means of short-term controlled temperatures of the melt and the material to be coated and short-term changes in the contact times of the material to be coated with the molten coating material.
  • the known systems are very expensive to build, with the melt having relatively high levels of contamination by oxides, by iron or in the case of zinc by light and heavy hard zinc, which affect the coating quality.
  • the present invention is based on the object of improving the conventional coil coating process in order to specifically achieve favorable intermediate layers for good adhesion and good formability of the coating.
  • the surface quality, the layer thickness tolerances and the mechanical properties of the material to be coated should be improved and the contamination of the melt by oxides, iron and hard zinc should be minimized.
  • the coating material to be applied should adhere firmly even to non-optimal surfaces of the steel strip. A significant reduction in energy consumption, production costs, maintenance costs and investment costs is just as possible as a quick change of the coating material.
  • a device for coating continuously cast material e.g. Copper wire is known, the material being passed vertically from below through a coating container without reversing the direction.
  • the coating container is connected to a melting furnace via a connecting pipe.
  • a diving bell is provided in the melting furnace, by means of which the melting bath level in the melting furnace can be adjusted. With this immersion bell, the molten pool level in the coating container can also be adjusted indirectly.
  • a device according to the invention is proposed, both of which, during the passage of the strand-like material, the molten coating material is held in a movement directed against the surface of the strand-like material and is circulated with the exclusion of atmospheric oxygen. It has been shown that particularly good coating results can be achieved if, according to the proposal of the invention, the molten coating material is kept in motion in the contact area with the surface of the material to be coated, by circulating the coating material in a closed system without contact of the melt with the Oxygen in the air is always fed fresh coating material to the belt. The bath movement also minimizes the size of the hard zinc particles.
  • An advantage of the device according to the invention is that the temperatures of the molten coating material and / or the strand-like material can be set at short notice. In this way, the optimal conditions for forming the intermediate layer and for adhering the coating material can be set as required.
  • the molten coating material is cleaned of impurities during the circulation. In this way it can be ensured that the impurities, which deteriorate the coating quality, do not come into contact with the material to be coated in the first place.

  • An adjustment of the liquid column of the molten coating material can be carried out effectively in that the known immersion body, which surrounds the strand-like material with an electromagnetic seal, can be raised and lowered in the inner container. With the aid of this immersion body, the molten coating material is displaced to the desired bath level, the electromagnetic seal keeping the section of the strand-like material to be coated that passes through the immersion body free of coating material.

With the help of this magnetic pump, which can be raised and lowered in the longitudinal direction of the feed channel, the molten material can be removed Feed the coating material from the closed container part of the pre-melting container into the inner container of the treatment container.
  • the open container part of the premelting container is assigned a loading device with which the coating material, for example in block form, can be introduced into the melt, so that the supply of coating material can always be supplemented.

  • This backstop is provided so that in the event of leakages or the need to quickly drain the treatment container, no melt can get into the feed part of the strand-like material to be coated. Melt that penetrates the through opening can be collected at the backstop and returned to the storage container via the discharge channel.
  • the backstop can be closed mechanically, preferably by a slide closure, the slide plate of which is designed as a scissor knife for severing the strand-like material.
