Definitions

  • the invention relates to methods and devices as well as an application of the method for the production of band-like or foil-like products from metallic or metal-oxidic material, wherein metallic or metal-oxide melt is applied from at least one storage container through at least one nozzle opening to the surface of a heat sink moving at a controlled speed.
  • a method and a device for the production of amorphous metal strips is known (EP 00268.12), wherein a metallic melt is pressed out of a storage container through at least one nozzle opening and allowed to solidify on the surface of a heat sink passed in the immediate vicinity of the nozzle opening.
  • the starting point is round nozzles with a diameter of 0.5 to 1 mm, the use of which indicates an optimal relationship between the nozzle opening, the distance of the nozzle opening from the heat sink surface and the speed of the surface of the heat sink for the production of amorphous metal strips. This should enable uniformly formed metal strips to be produced at higher production speeds.
  • Such ribbons can either be completely amorphous or comprise a two-phase mixture of the amorphous and the crystalline state.
  • An amorphous metal alloy is understood to mean an alloy whose molecular structure is at least 50%, preferably at least 80%, amorphous.
  • a method and a device for producing a metal strip are also known (DE-PS 27 46 238), according to which various nozzle shapes for producing "wide” metal strips are proposed, which are complicated to produce in practice.
  • the largest stripe width achieved was 12 mm.
  • this proposal it is also pointed out that it must in principle be possible for a large number of parallel, uniform nozzles to be incident on a moving substrate from a suitable distance in order to form a relatively wide strip.
  • this attempt presents difficulties, particularly since the jet streams do not combine to form a pool, so that it is practically difficult to obtain strips with a uniform cross section.
  • DE-PS 27 46 238 devices with very close to the heat sink surface graduated nozzle shapes have been proposed to overcome such difficulties, with the help of strips with more uniform dimensions in terms of width and thickness and with uniform strength properties up to the range of the width specified above to let.
  • a nozzle body with a curved surface and a slit-like nozzle opening for influencing the flow conditions between the nozzle body and the surface of the heat sink is known (EP-0040069).
  • the tapes produced with this have predominantly an amorphous structure. It will also be the coating described the heat sink surface with different materials, but this only with a view to achieving certain physical surface properties, in particular for the flawless and easy detachment of the tapes produced from the heat sink surface.
  • a drum-shaped heat sink is known from GB-2083455, which contains a circumferential groove. The circumferential groove on the drum serves to a certain extent as a casting mold for a relatively thick strip of material that can later be cut transversely into slices, as are usually used in semiconductor production.
  • Tapes produced according to this method can be used in a particularly advantageous manner for cladding or lining mechanically or chemically stressed parts, for example of pipelines in order to make them corrosion-resistant, or of slide bearings.
  • Such products are easier and cheaper to produce when using tapes or foils produced according to the invention than the products manufactured by traditional methods.
  • the products produced by the proposed method have better technological properties than conventionally manufactured products, for example by a powder metallurgical method.
  • geometrically delimited areas can be defined by segmentation, perforation or profiling of the heat sink surface, so that on the one hand foils with a structured surface and on the other hand those with shape-limited individual areas can be produced. The mass production of small parts from tape or film material is thus possible in a simple and expedient manner.
  • the device for carrying out the process shown schematically in FIG. 1 contains a continuously rotating drum 1 acting as a heat sink, storage container 2, with one or more nozzles 3, for example with a nozzle slot, and an inductive heating device 4 for heating the ones in the storage containers 2 located melt. Any other temperature-stabilizing device can also be used instead of the inductive heating device.

  • the reservoir 2 can also be slightly overpressured from the Gas container 6 may be acted upon.
  • any other devices for generating a pressure difference between the storage container and the nozzle openings can also be provided, for example mechanical or electromagnetic pressure difference generators known per se.

  • the nozzle heads on separate storage containers 2A, 2B, 2C are offset from one another in the direction of movement Y of the drum 1.
  • the areas of action of the nozzles or nozzle groups belonging to the individual storage containers connect seamlessly to one another transversely to the direction of movement Y of the drum 1.
  • different material webs can be produced with areas of different material directly adjoining one another, the transitions between the areas taking place along a sharp dividing line. This is achieved by controlling the process parameters, melt temperature, distance of the nozzles from one another and speed of movement of the drum surface in such a way that a second melt of different composition from the second reservoir 2B is melted directly onto the already solidified melt from the reservoir 2A. This creates a uniform layer of material that can be removed as a whole from the drum surface.

  • curved abutting surfaces are provided between the modules, which allow the through nozzle slot to be self-centered in a particularly advantageous manner.
  • the nozzle modules according to FIG. 8A each contain a slot nozzle and inclined butting surfaces.
  • a module contains several, in the example two staggered slot nozzles, oblique butting surfaces being provided between the modules and the nozzle slots also staggering over the butting points.

  • F ig. 9 B shows an embodiment in which adjacent, inclined nozzle openings each other such overlap, that the bent or flared ends of the nozzle openings overlap üsenmodul in the adjacent D; so no special start and end modules are required.
  • a device according to FIGS. 1 and 2 was used, in which a multiple nozzle arrangement with an overlap G of 1 mm, an offset D of 3 mm, one Nozzle slot width of 0.3 mm and a distance of the nozzles from the substrate surface of 0.3 mm was set.
  • the casting speed is 1.2 km / min.
  • the size of the individual nozzle was 2.0 ⁇ 0.3 ⁇ 35 mm, and the nozzle distance from the substrate surface was 0.3 mm.
  • the casting speed was chosen the same as in the previously mentioned example.
  • composite materials of various types can be produced, for example as a sandwich of different metal alloys, or in the context of the isostatic pressing of fiber materials, strips and the like.
  • films or tapes produced according to the described method pipes or transport lines can also be lined or clad so that, for example, they have a corrosion-resistant surface made of high-quality material, while the carrier material can be a simple and inexpensive mass product.
  • Large-area coatings of this type can be achieved by means of a plurality of material webs abutting one another, the joint areas between the material webs running side by side being able to be treated in an additional process step in such a way that a homogeneous surface of uniform structure results.
  • the additional process step can be carried out, for example, with the aid of "laser glassing".

  • the cooling potential of the surrounding material is sufficient to cover the melted volume with very high cooling rates, e.g. solidify in the range between 10 and 10 5 degrees Celsius per second, so that an amorphous material structure can also be produced there.
  • surfaces of pipes or shafts for example, can be highly tempered, and workpieces with relatively large dimensions can also be provided with a tempered or hardened surface.
  • the device for carrying out the method shown in principle in FIG. 10 contains a continuously rotating drum 1 acting as a heat sink, a storage container 2 with at least one nozzle opening 3 and an inductive heating device 4 for heating the melt located in the storage container 2.
