Definitions

  • the invention is directed to an electrode support arm for electric arc furnaces, which is designed as a, in particular box-shaped, hollow steel profile with an electrode receptacle arranged at its front end, wherein the hollow steel profile has at least in regions an outside wall region formed of copper as a high-conductivity current-carrying material.
  • the invention is directed to a method for producing a Elektrodentragarms for an electric arc furnace with an outside at least partially on a preferably polygonal, especially square, hollow steel profile formed wall portion of copper as a current-carrying material of high conductivity, wherein the hollow steel profile is welded together from cut steel plates or steel sheets.
  • Electrode support arms for electric arc furnaces such as electric arc furnaces, ladle furnaces or reduction furnaces, such as those used in steelmaking, are used to hold electrodes, which are usually cylindrical and made of graphite. These electrodes are held in an electrode receptacle formed at the front end of an electrode arm and moved by height-variable movement of the electrode support arm into the electrode holder respectively retracted desired position within a fitted with these electrodes furnace of the aforementioned type.
  • the brackets are then welded and manufactured from the blanks. Due to the copper (Cu) -plating, welding, which takes place essentially in the corner regions of the respective hollow steel profile, is expensive. For welding, first of all, the copper-clad steel sheet has to be cut off at an angle, before the adjoining corner edge areas are then welded together. The resulting outside of the weld must be smoothed. Thereafter, a copper intermediate piece is applied in a manner covering the steel weld in the region of the resulting corner or edge of the hollow steel profile. To continue the copper cladding of the steel plate or steel sheet used, a copper weld is placed between the copper spacer and the cladding.
  • Cu copper
  • the invention has for its object to provide a solution that makes it possible to produce electrode support arms for electric arc furnaces cheaper and less expensive.
  • this object is achieved in that the wall area is applied as a galvanic copper coating on the hollow steel profile.
  • this object is achieved in that the wall region of copper is applied as a copper plating on the hollow steel profile.
  • the invention is based on the way to manufacture the box-shaped or polygonal hollow steel profiles from simple, unplated steel sheets, which preferably have a thickness of 20 mm, by welding. Thereafter, this part of the electrode support arm, but preferably the complete, also the electrode holder at its front end having electrode in galvanically coated with copper in a galvanic coating system.
  • the outside wall region of the electrode support arm which is to be made current-carrying from a material of high conductivity, is applied as a galvanic copper coating in a layer thickness of 8 mm in particular on the outside of the steel sheet of the hollow steel profile of the electrode support arm.
  • the parts or regions of the steel hollow profile or the electrode support arm that are not to be coated with copper are covered with a conventional coating material, such as a paint or wax or foil, after galvanic copper coating this coating is then peeled off.
  • an electrode support arm according to the invention is less expensive and less expensive to manufacture than in the known prior art.
  • This simple steel hollow section construction is then galvanically coated with copper.
  • the entire steel hollow profile or the entire electrode support arm can be provided with a copper coating in the desired thickness in one operation, in which case in particular the welds are completely completely coated with copper, so that reworking is not necessary here.
  • a uniform copper coating on the outside of the hollow steel profile is formed by this surface coating, which in the application for a uniform and the same electrical conductivity on the surface of the hollow steel profile and thus the Elektrodentragarms care.
  • the invention therefore further provides that the hollow steel profile has all around on all outer and / or on the inner sides of the walls or side surfaces a flat galvanic copper coating.
  • the copper coating is advantageously produced by flowing through the welded hollow steel profile of an electrolyte liquid which is in operative connection with a copper electrode introduced into the hollow steel profile.
  • the hollow steel profile has a polygonal, in particular square, cross section and is welded together from steel plates or steel sheets.
  • the hollow steel profile can also be tubular.
  • the copper coating can be produced galvanically by immersing the hollow steel profile or the electrode support arm in an electrolytic galvanic bath in operative connection with a copper electrode.
  • the invention provides in a further embodiment that the galvanic Copper coating is produced by immersing the welded hollow steel profile in an electrolytically active electroplating bath which is in operative connection with a copper electrode.
  • Coating plants which have the necessary size for coating an electrode support arm and the possibility of coating components of this weight with copper are known from the prior art.
  • coating systems are known in which the coating process is carried out in large pipes, in which the respective electrode support arm or the respective hollow steel profile and one or more copper anodes are introduced.
  • an electrolyte flows through the tube and the coating process starts after a voltage has been applied to the anode and the steel hollow profile or electrode arm to be coated.
  • any other sufficiently large and filled with an electrolyte galvanic basin can be used as a coating system.
  • the method is characterized in that the hollow steel profile for application of the copper coating is immersed in an electrolyte-containing electroplating bath which is in operative connection with a copper electrode.
  • the hollow steel profile is galvanically coated from the inside with copper.
  • the hollow steel profile serves as hollow body through which electrolyte flows, into which one or more copper electrodes are inserted, so that the inner walls of the electrode support arm are galvanically coated with copper for power conduction.
  • a galvanic copper coating in a thickness of 3-15 mm, preferably 6-10 mm, in particular 8 mm is applied.
  • the invention is characterized by the fact that the hollow steel profile is introduced for application of the copper coating in a pipe through which an electrolyte flows.
  • An existing essentially of such a large pipe coating plant is particularly suitable for carrying out the method according to the invention.
  • the FIG. 1 show a consisting of three Elektrodentragarmen 1, 2, 3 Elektrodentragarm set of an electric arc furnace in a schematic perspective view.
  • the individual electrode support arms 1, 2, 3 are each made of a box-shaped profile 4, 5, 6 made of 20 mm thick sheet steel.
  • the individual side walls of each hollow steel profile 4, 5, 6 each consist of a steel plate, wherein the steel plates are welded together at the corner edges of the respective hollow steel profile 4, 5, 6.
  • As outside wall area is at least in each case a side surface 7, 8, 9 of a hollow steel profile 4, 5, 6, but preferably the entire respective hollow steel profile 4, 5, 6, covered with a galvanically applied copper coating.
  • a conventional electrode holder 10, 11, 12 is arranged and formed.
  • the copper coating 7, 8, 9 is formed as a current-carrying layer of high conductivity, so that over it in the electrode holder 10, 11, 12 respectively to be arranged electrodes made of graphite can be acted upon accordingly with current.
  • the coated with a copper coating 7, 8, 9 electrode support arms 1, 2, 3 are used in equipped with electrodes arc furnaces, such as electric arc furnaces, ladle furnaces or reduction furnaces use.
