Definitions

  • the invention relates to a component for a continuous casting mold, such as water tank, adapter plate, etc., to which a copper plate is attached and a method for producing the component.
  • electromagnetic brakes or stirrers are used to influence the flow in the mold, especially in the region of the casting mirror.
  • the electromagnetic brakes or stirrers consist of magnetic cores of a ferromagnetic material, which are wholly or partially wound with magnetic coils. Magnet cores and coils can be arranged in different ways and interconnected to achieve the desired effect on the flow in the mold.
  • the distance between the ferromagnetic core and the melt in the mold to be kept as low as possible, because the strength of the magnetic field decreases disproportionately with the distance.
  • WO 2004/022 264 A1 discloses an electromagnetic brake device for molten steel flowing into a continuous casting mold.
  • This comprises at least one magnetic coil with a ferromagnetic core which can be assigned to the broad side of the mold.
  • the core consists on the one hand of a magnetic coil receiving, movable in the distance to the broad side walls main body, and on the other hand in the Wasserkals- The mold parts fixedly arranged additional parts, wherein the core parts in collapsed operating position U-shaped yokes to form a closed magnetic flux, and result in an extended position, an interruption of the magnetic flux.
  • the brake comprises at least two magnetic cores, which are arranged on one side of a mold and fixed thereto, and a yoke, which is detachably connected to the two magnetic cores and connects them, wherein the yoke at least one winding substantially between the two, magnetic cores, which are connected by the yoke wears.
  • the winding around the yoke is wound such that the central axis of the winding is substantially parallel to a longitudinal side of the mold which extends the central axis of the winding substantially perpendicular to the casting direction in the mold so that the magnetic cores are permanently attached to the mold and that the magnetic cores cover substantially the entire width of the mold except for a central portion of the mold.
  • the ferromag netic cores in the water tank are arranged so that over the mold width, a different strong magnetic field is generated.
  • the performance of induction stirring in the molten metal comprises inducing electromagnetically the stirring of molten metal with an intensity which normally results in turbulence in the molten metal including its free surface, by applying a rotating magnetic field to the molten metal, and applying a second rotating magnetic field generated by a source separate from the source supplying the first magnetic field and at a location upstream of the stirring, the first rotating magnetic field rotating in the same direction as the direction of rotation of the first field to increase the stirring movement in the area of the free surface but exerts a torque on the molten metal which is lower than the torque exerted by the first field.
  • EP 0 820JJ24 B1 discloses a continuous casting machine with a magnetic field formed in the region of the continuous casting mold, wherein each central core of a magnet is enclosed by coil windings and the central cores are connected to one another by a yoke surrounding the mold.
  • each magnet has a central core, which divides kokillen matter in at least one upper core for an upper magnetic field and a lower core for a lower magnetic field, whereby a resulting magnetic field in operation with respect to the continuous casting mold in at least one oes and a lower magnetic field is split.

  • the object of the invention is to design and simplify the known components of a continuous casting mold such as water tank, adapter plate, etc. in such a way that the strength of the magnetic field is increased and the effectiveness of the magnetic field is improved and the abovementioned disadvantages are avoided.
  • a component according to the preamble of claim 1 is formed of at least two different materials, one material is magnetic and the other material is non-magnetic.
  • the invention also relates to a method for producing the component according to the invention.
  • the component is produced according to the invention by welding, by at least one magnetic single element is connected to a non-magnetic single element.
  • the decisive advantage of the method according to the invention is that even thick-walled components made of materials with different magnetic properties can be produced by welding. It is important that during welding, during the subsequent processing of the components and in the casting operation residual stresses do not cause the components to discard. Defects, voids and cracks in the weld must also be avoided.
  • electroslag welding is used.
  • a molten bath is produced between the two individual elements to be welded, which are arranged at a distance of a few mm from one another.
  • the respective surfaces of the individual elements become partially liquid upon contact with the melt.
  • welding wire is fed to the molten bath. According to the amount of the supplied welding wire, the volume between the individual elements is slowly filled from bottom to top. The molten bath solidifies continuously. In the manufacture of the component is welded in the seam longitudinal direction.
