Definitions

  • the invention relates to a method and a system for regenerating or realigning open section steels, preferably sheet piling sections or watertight piles, which are used in engineering and industrial buildings.
  • the object of the invention is to provide a method adapted for the regeneration of profile bars and a corresponding system, which enable the repeated use of deformed open profile steels in use.
  • This object is achieved by a regeneration process for deformed profile steels in that the profile steels are locally preheated to the metal-plasticizing temperature and then pulled through a guide with a corresponding profile opening.
  • a suitable system for carrying out this regeneration process is characterized in that it is aligned directly in front of a housing with an exchangeable guide and a corresponding profile opening with a plurality of burners and is provided with a broaching machine to which the profile steel to be regenerated is connected in a known manner .
  • This system can be equipped with one or more guides, depending on the profile required for the profile steel to be regenerated.
  • the system can also be provided with a sprinkler, which un is arranged indirectly after the profile opening.
  • An advantage of the system according to the invention is that losses of profiles can be avoided, in whole or in part, and that profiles can be used several times without limiting the area of use.
  • the invention is explained in more detail below using an exemplary embodiment with reference to the drawing.
  • the drawing shows schematically a plant for the regeneration of open section steels.
  • the regeneration system consists of a number of adjustable acetylene burners 1, by means of which a section steel 2 to be regenerated is preheated to the appropriate metal-plating temperature, a stationary steel plate 3 with an exchangeable guide 4 with a section opening 5 in the form of the corresponding section, for example for sheet piling steel , a coolant tank 6, sprinkler nozzles 7, a mechanical broaching machine 8 and a steel cable 9, which is equipped with a mandrel 10, which is inserted into a pre-drilled opening 11 in the sheet pile steel.
  • the regeneration system according to the invention works as follows.
  • the profile steel 2 to be regenerated is inserted with the less deformed end into the profile opening 5 of the guide 4, whereupon the mandrel 10 of the steel cable 9, which is wound onto the drum of the mechanical broaching machine 8, is inserted into the correspondingly “predrilled opening 11 of the profile steel 2
  • the section steel 2 is then heated to the plasticizing temperature, after which it is pulled through the section opening 5 of the guide 4.
  • the section steel 2 is cooled with cold water or another liquid from the cooling liquid container 6 with the aid of the sprinkling nozzles 7.
