  • the invention also relates to a plant for treating strands.
  • a furnace is provided with which a strand, in particular a continuous casting rod or a continuous casting bolt before further treatment, for example by a pair of scissors or a press, is heatable to forming temperature.
  • a furnace of the type mentioned is basically made DE 10 2004 020 206 A1 and DE 20 2004 006 551 U1 known. It is a furnace for heat treating continuously cast bars or continuous cast bolts, which can be heated to a forming temperature before shearing the billet and then pressing in a press in the furnace system. In the furnace plant, a plurality of shaft elements for axially transporting continuous casting rods or continuous casting bolts is provided.

  • the invention has recognized that a burner nozzle of the type mentioned, in particular a burner nozzle for a system, in particular for a furnace plant, in particular for a plant for treating strands of the type mentioned in principle, is capable of sufficient heat to treat
  • the heat transfer from the burner nozzle to a strand in a conventional burner nozzle of the type mentioned can have irregularities due to the burner flame.
  • the amount of heat that ultimately acts on a strand can thus be subject to fluctuations and, if necessary, an insufficient amount of heat may temporarily be present.
  • conventional devices of the type mentioned are unreliable and therefore not reliably controllable.
  • the invention is based on the assumption that a reliable heat transfer in the context of flame stabilization of the burner nozzle is feasible.
  • Flame stabilization can be achieved according to the invention in a burner nozzle by swirl generation at the flame downstream of the nozzle insert.
  • the concept of the invention provides for formation of a swirl generation zone downstream of the nozzle insert such that the burner sleeve projects beyond the nozzle head and the nozzle insert has a number of nozzle channels and means for swirl generation are provided. It has been found that this concept enables the stabilization of a burner flame in a particularly advantageous manner.

  • the longitudinal axis of a nozzle channel extends inclined to a radial plane along a longitudinal axis of the burner sleeve.
  • a partial flow of the flow mixture produced in the direction of a specific angle of inclination to the burner sleeve is deflected by the part of the burner sleeve projecting beyond a nozzle insert in the said zone for generating swirl.
  • a twist is imparted to the total flow of the flow mixture, which in a rotary motion, ie swirl movement, of the total flow in itself acts behind an opening of the burner sleeve.

  • the nozzle insert has a taper projecting beyond the annular region downstream, which protrudes into the zone.
  • a flow mixture exiting from a nozzle channel has a substantial profile which can be deflected at least once on an inner side of the burner sleeve.
  • a flow mixture emerging from a nozzle channel has a substantial profile which can be deflected at least twice on an inner side of the burner sleeve. It has surprisingly been found that a total flow despite twice deflection nevertheless has a sufficient overall speed, so that for a heating of a strand, for example in a furnace mentioned above, a sufficient range of the burner flame can be realized in order to realize a sufficient heat transfer.
  • a relatively improved swirl movement is achieved by a two-fold deflection and thus a particularly good stabilization of the burner flame.
  • a second deflection takes place in the region of a mouth stage of the burner sleeve. In the case of a diversion in the area of a mouth stage, a particularly good utilization of the zone for swirl generation takes place.
  • the means for swirl generation is formed by a nozzle channel having a means for spin generation in the flow mixture.
  • the means for spin production can be realized in particular by, for example, helically extending grooves or webs in a nozzle channel and / or by one or more suitable curves of a nozzle channel.

  • a contactless temperature measuring device for a burner nozzle output is arranged in at least one of the control zones. While non-contact temperature measurement has proven to be particularly advantageous in principle, there is often the problem, in particular in the temperature measurement of aluminum bodies, in particular aluminum strands, that the heat emission coefficient is only significant for the body temperature for a short time. In other words, the heat emission number is usually subject to fluctuations or is distorted and therefore proves to be generally not sufficiently constant for a non-contact temperature measurement. This problem has been recognized according to a particularly preferred embodiment of the invention.
