Definitions

  • the subject of the invention is the production method of a coated wire having a metal core on which a lag of other metal is placed.
  • the invention concerns the method of producing the coated wire in a continuous process on an industrial scale.
  • the materials used for the production the coated wire should have specially chosen features such as a melting temperature and mechanical durability.
  • the wire being the core of the product should be metallurgically homogenuous, not polluted, and made by a drawing technology.
  • the soldering method of producing a coated wire has been known. Steel wire being the core of the product is covered with a thin layer of brass and is placed in a covering of cooper sheet. Next, all is heated up to the temperature in which the layers of metals are joined. It is impossible to get a good quality coated wire using this method. Connecting metals by soldering is not long-lasting and, moreover, adding brass interferes with electrical conductivity.
  • the annealing of a steel wire with a cooper coat takes place in the temperature of about 650 degrees Celsius, which causes the diffusion of cooper atoms into the steel core and iron atoms into cooper.
  • This method requires the selection of materials of specially selected properties.
  • the core wire should be of high purity steel and the coat demands the usage of oxygen-free, vacuum cooper.
  • the process is very complicated and requires many operations such as the roughening of the surface of wire, crimping the outer layer of sheet, welding of seam, drawing and annealing.
  • the electrochemical way of producing a coated wire has been known. This method makes use of the electrolysis and introduces the core wire into the electrolytic bath containing salts of the metal of a coat layer surface.
  • coated wires with a core of alloy steel or alloys of different metals is also possible.
  • the wire before the process of electrolysis, the wire passes through the degreasing, washing and electrolytic pickling baths, and after the process it passes through cleaning, finishing touches, and other similar baths.
  • the main drawback of the known methods is the ability to perform only thin coating.
  • the aim of the invention is to develop a new method of producing a coated wire, enabling making the laggings of any thickness assuring high quality and lower manufacturing costs.
  • the essence in producing a coated wire is putting the wire core into the molten metal, its passage through a crystallizer and exit outside with the wrapping of chilled metal.
  • the method of manufacturing a coated wire enables to produce the wire in a continuous process using industrial methods.
  • this method there is no restriction as to the thickness of the metal lagging neither to the shape and size, which can be optional, of a cross-section of the finished product.
  • the method, according to the invention is environmentally friendly and meets environmental requirements.
  • the method of manufacturing a coated wire is shown in the example of the invention in the device where Figure 1 shows a schematic view of the device and Figure 2 shows a cross-section of the crystallizer.
  • Figure 1 shows a schematic view of the device and Figure 2 shows a cross-section of the crystallizer.
  • the example demonstrates the way of producing a coated wire with a low carbon steel core with copper lagging.
  • Steel wire 1 is being placed by the guidance wheel 11 , the set of straightening rolls 9 and centering head 4 into the furnace chamber 3 with molten copper of a temperature of 10830 degrees Celsius.
  • Steel wire 1 heats up from the molten copper to a plasticity temperature of steel and is centrally directed to crystallizer 5 where it is gradually cooled. During the passage of wire 1 through the molten copper the diffusion of copper atoms to the wire 1 and the diffusion of iron atoms to the created copper lagging takes place. In the upper zone 6 and in the central zone 7 of the crystallizer 5 the turning from the liquid copper into the solid state which creates the lagging of the coated wire takes place.
  • the lower part 8 of the crystallizer 5 is a cooling zone and the coated wire 2 being placed into and having full mechanical strength is pulled outside by a set of pulling wheels 10 .
  • the coated wire 2 is guided by the directing wheel 12 for being wound on a drum.
  • the furnace for melting has an atmosphere of nitrogen protecting molten copper from oxidation.
  • the method of producing the coated wire, according to the invention is particularly useful for wires with low-carbon steel or alloy steel core with cooper, aluminum, tin, silver or gold lagging.
  • High quality coated wires with a smooth surface are good medium for the surface currents at high frequencies.
  • Such wires can be used for electronic transmission of information, in digital transmission networks type LAN, signaling systems, etc.
  • Coated wires with steel core which, as a result, has higher mechanical durability can be applied in power industry and rail transport.
