Definitions

  • ABSTRACT Profiled metal products are continuously cast by maintaining a nozzle having an upper cooling zone immersed into a melt to receive and cool the melt.
  • the nozzle is immersed so deep into the melt that the point of solidification of the received melt is below the surface level of the outside melt and the solidified smelt is then pulled upwards while being further cooled.
  • a disadvantage of this process is that, when the nozzle is changed, at least the part of the furnace to which the nozzle has been attached must be freed from the melt, that is, the furnace must be emptied or tilted so that the area concerned is left above the melt surface. This disadvantage is especially noticeable when several nozzles have been attached to the same furnace. Their ages of duration are not the same, but since they all must be changed at the same time, some of them have to be out of use for some time, and some of them will be removed from use too soon. In addition, it is always possible in the process that melt will discharge freely out through the nozzle, in which case the employees and equipment are easily harmed.
  • the nozzle inlet is maintained at such a depth below the melt surface that also the solidification front of the received smelt is below the level of the melt outside the nozzle.
  • FIGURE shows an elevational section of an especially preferred embodiment of the invention.
  • a core 8 has been attached inside the nozzle and centered with the help of a guiding surface 10.
  • the material of these parts is usually solid graphite, but it can also be some other material, for example, sintered alloy of metal and metal oxide.
  • Passages 12 run through the base of the core 8. Melt is conducted through the passages 12 into the solidification area between the nozzle 7 and the core 8.
  • the nozzle 7 has been attached to the metal chill mold 2 by threading shown at 9 so that it conducts heat well. Cooling water runs to the chill mold 2 through pipe A. The water is forced to run to the lower end of the chill mold along the space between the outer pipe 4 and the intermediate pipe 3 and then up along the space between the intermediate pipe 3 and the inner pipe 2 and out through pipe B.
  • the lower end of the chill mold 2 is protected by a fireproof lining 6 which is attached so tightly to the lower end of the nozzle 7 by, for example, a conical surface ll and a nut 5, that melt will not get into contact with the metal chill mold' 2.
  • the basis of the operation of the device is that the chill mold is immersed from above so deep into the melt that teh solidifying front 13 is below the free surface 14 of the melt.
  • the solidified pipe generally indicated by the reference numeral 1 is drawn upward by a drawing apparatus situated above the device and not shown in the figure.
  • the continuation of the inner pipe 2 above the upper surface of the nozzle 7 works as an after-cooler of the already solidified pipe.
  • the inner surface of the forming pipe is determined by the diameter of the core at the solidifying front 13.
  • the device presently described differs from the one described in the U.S. patent application Ser. No. 95,038 in that it is not necessary to use differences of pressure in relation to the open air.
  • the use of underpressure would cause great technological difficulties since the entire cast pipe ought to be in the same pressure.
  • the cutting of the product should also take place without disturbing the underpressure prevailing inside the pipe.
  • the construction of an underpressure chamber is particularly difficult when the purpose is to cast very long pipes, for example, m long.
  • a device according to the invention can be used for the production of casts of unlimited length.
  • the diameter of the cast is determined by the nozzle 7 and the core 8.
  • the advantages of the device are most obvious in casting pipes.
  • a device according to the invention can be used, by removing the core, for the continuous casting of bars and different profiles, plates, etc.
  • An improved apparatus for casting profiled products continuously upwards from a melt having: a support above the melt; a vertical cooler attached to the support, said cooler comprising a plurality of concentric pipes defining a passage therebetween having an inlet and an outlet for coolant medium; and means for pulling solidified product upward through the cooler, the improvement comprising a nozzle coaxially attached to and partially surrounded by the lower end of the cooler to cool the upper portion of the nozzle and a fireproof lining encompassing the nozzle and at least the lower part of the cooler.
  • the nozzle has an outer surface which expands conically toward the lower end of the nozzle and the lower end of the lining has an inner surface mating with and resting on said conical outer nozzle surface, the upper end of the lining being fixed to the cooler by means of a nut.
  • a device for immersion into molten metal for upward casting of elongate elements from the molten metal including a nozzle, a cooler surrounding only an upper part of the nozzle to provide a cooling zone within the upper part of the nozzle for continuously cooling molten metal within the nozzle to form a solidified product below the surface level of molten metal into which the device is immersed, and a fireproof sheath surrounding the nozzle and also surrounding at least a lower part of said cooler.
