Definitions

  • the invention relates to a method and a plant for the continuous casting of Casting formats close to the final dimensions for further cold forming Non-ferrous metals, especially from strips, bars or tubes Copper or copper alloys.
  • EP 0203867 B1 describes a device for the continuous casting of Metal products known in which the liquid metal from a Pouring ladle into a continuously loaded form and from there one Extractor and secondary cooling device is supplied. After Through solidification, the finished belt is deflected and on one Coiler device wrapped.
  • the device known from this document has neither means for Surface treatment of the belt still for cross division.
  • the invention aims to provide a method and an installation for to create continuous casting of any profiles with the constructively simple means endless casting strands made of copper or Copper alloys with a minimum of metallic losses in the Desired delivery quality and formats for later cold forming to be brought.
  • the strip is continuously cast in a vertical position, the tape being pulled off centrically after it solidifies and directly into a surface treatment machine is threaded. Because of the exact Leading the strand emerging vertically from the mold is the It is not necessary to use a threading machine. With a system with oscillating mold and continuous strand movement are above it Furthermore, no special facilities for adapting the Surface treatment machine required for the strand movement.
  • a special product free of segregation is used when a high-frequency moving vertical mold and more linear Strand withdrawal speed produced.
  • the strip which is free of defects after the removal of surface material can then be treated as desired, for example bent and wound up immediately thereafter.
  • This process is of particular importance in the continuous casting of alloys which tend to segregate, in particular tin-bronze or phosphorus-deoxidized copper.
  • tin bronzes on the strand surface can have brittle phases due to tin accumulations, which lead to the formation of surface cracks. If, for example, such a strip is bent without pretreatment, these cracks are reinforced in the following way: The surface cracks on the outside of the curved band deepen, the cracks on the inside are first compressed, and become particularly wide when bent back later due to the previous upsetting.
  • the surface removal still takes place vertically Area of the tape removed the brittle phase, so that subsequently Band can be deformed as desired.
  • Band quality is u. a. by reducing the mechanical Processing increases yield and by avoiding Surface defects significantly expanded the production program.
  • the system according to the invention requires only one with the foundation connected base frame on which the pulling device, the Surface processing device, the separator and, if necessary, the Belt deflection are arranged.
  • the usually higher ones The investment costs of a vertical system are clear decreased.
  • An arrangement of a quiver offers a particular advantage in the strand take-off direction immediately below the separating device, because with it the production of particularly bend-sensitive material becomes possible.
  • FIG. 1 shows one arranged on a casting platform 53 Casting device, consisting of a distributor 11, a hot-top 12, a mold 13, including an oscillation drive 14 Secondary cooling is connected, which is above one Cooling water distributor 15 is arranged on the guide rollers 16th are provided.
  • the casting device becomes a strand S by means of a pull-out device 22 deducted in the vertical direction.
  • a pull-out device 22 deducted in the vertical direction.
  • a milling machine 23 close in the direction of the tape Surface treatment machine, here a milling machine 23, and one Separating device, here a pair of scissors 24, which together on a the base frame 21 connected to the hut foundation 51 are arranged.
  • the devices for extending 22, for surface treatment 23 and Disconnect 24 are accessible from a work platform 52, which one Has opening 54 through which the connection of the devices 22 to 23 with the base frame 21 permits.
  • the base frame 21 receives a bending device 25 and a conveyor device 41.
  • the strand S is deflected in its conveying direction by the bending device 25 and fed to a strip reel or strip rolling machine 31 arranged on a base frame part 26.
  • the strand S itself can - as above described - deflected by closing the bending device 25 and a reel or reel-in 31 are fed.
