Definitions

  • the invention relates to a multiple mold for the vertical continuous casting of non-ferrous metals, which consists of a closed mold frame serving at the same time for the cooling water supply and several individual molds, which in turn have an integrated water chamber and an annular spray gap or a spray hole rim. This is a state of the art known to the applicant and not recorded in printed form.
  • multiple block molds that have a coherent, common water chamber
  • those in which single molds sprinkled from the outside are used
  • International Metals Reviews, London / Metals Park, June 1976, vol. 21, p.84, Fig. 14 / a, c and d and DE-C-1 758 574 are not the subject of the invention.
  • the continuous casting mold having an integrated water chamber is superior to the mold sprinkled from the outside. Because it has a precisely defined and directed water outlet opening - annular gap or ring of holes - this so-called gap or ring of chill mold can fulfill its task, namely the uniform cooling of the strand, better than the mold sprinkled from the outside.
  • the externally sprinkled continuous casting mold is more sensitive to pressure fluctuations in the water supply network than the split or perforated ring mold and cannot produce a similarly uniform and intact water curtain as e.g. B. a well-designed split mold.
  • the mold sprinkled from the outside has become more and more important as a component of a multiple mold in recent times because it is much simpler and cheaper than the split or perforated ring mold, and because the format change can be carried out quickly and easily with replaceable mold sleeves, which is very important in modern large systems.
  • a mold frame is used according to the prior art, on which the individual molds are firmly mounted.
  • the mold frame which also serves to supply the cooling water, is designed as a water pressure chamber to which each individual mold is connected by one or more lines.
  • the main difficulty in the construction of a continuous casting mold having an integrated water chamber is that the cooling water introduced laterally into the mold through only one or a few lines must be distributed within the mold chamber in such a way that the mold wall is cooled uniformly along its circumference on the one hand, and on the other hand the cooling water flows down in the direction of movement of the strand with the exclusion of any significant transverse movement along the surface of the strand.
  • the invention has for its object to provide a multiple mold of the type described, which does not have the shortcomings of the known multiple molds, d. H. It is simple and inexpensive to manufacture, enables a quick change of format, takes up little space, is easy to clean and, above all, ensures uniform mold wall cooling and a perfect splash-water veil free of cross currents. In the multiple mold according to the invention, it should also be possible to move and / or lift the individual molds on the mold frame.
  • the multiple mold according to the invention thus consists of a box-shaped, closed mold frame, which acts as a water pressure chamber is designed and the holder and water supply for the individual molds, as well as from several individual molds, which in turn have an integrated water chamber and either an annular spray gap or a spray hole ring.
  • To transfer the cooling water from the mold frame into the individual molds as many openings are formed on the upper side of the mold frame as the multiple mold must accommodate on individual molds.
  • the individual molds in turn have water inlet openings arranged on the lower side of the openings of the mold frame.
  • the individual molds are placed on the mold frame and pressed against the upper side of the mold frame by their own weight or also by additional contact pressure. This creates a connection between the water pressure chamber of the mold frame and the water chambers of the individual molds, and a complex multiple mold is formed from the mold frame and the individual molds.
  • the water transfer openings of the mold frame, or the individual molds are selected so that either the mold frame has annular slots and the individual mold holes. wreaths or vice versa, or have both perforated wreaths.
  • the individual molds can have either an annular spray gap or a spray hole rim. If, however, the openings of the mold frame are designed in the form of perforated rings, the individual molds can accordingly only have one spray hole ring as the water outlet opening. This design enables the single molds to be formed from one piece using the casting process.
  • both the mold frame and the individual molds have perforated rings, the holes in the perforated rings of both parts are arranged in the same way, so that when the single-molds are placed on the mold frame, there is a hole.
  • This version is suitable for rectangular molds, where the mold cannot be rotated on the mold frame.
  • the cooling water rinses the outer wall of the molds, then the surface of the solidified ingots emerging from the molds.
  • the annular water chamber of the individual molds in contrast to the known continuous casting molds, is designed to be quite low in the multiple mold according to the invention, since it practically only has the task here of transferring the cooling water from the mold frame to the water outlet openings of the mold in the shortest possible way.
  • this cooling water system the occurrence of cross currents in the water chamber or even in the splash water curtain of the individual molds is ruled out, because the flow lines, starting from the closely spaced vertical transfer holes of the sieve-like row of holes, are of the same length and naturally only run in vertical planes.
  • the water transfer openings (annular slots or perforated rings) of the mold frame or the individual molds are preferably of different widths, so that the full water transfer cross-section is retained even when the individual molds are moved or inaccurately placed.
  • the water transfer openings of the mold frame and the individual molds can be interrupted according to the invention in the corner regions of a rectangular individual mold.
  • a shallow depression can be formed on the upper side of the mold frame for each individual mold, the contour of which runs parallel to the outline of the individual molds and whose circumference is equal to or greater than the extent of the individual molds. wherein the play of the individual molds in the shallow depressions is smaller than the play between the water transfer openings in the mold frame or in the individual molds. These recesses serve as seats for the individual molds.
  • the individual molds can be placed on the mold frame either without or with the interposition of seals. If no seals are used, leakage water can escape at the connection points.
  • an annular groove can be formed on the side wall of each recess, from which the leakage water is discharged into the casting pit through vertical drainage pipes starting from the groove and fastened in the mold frame.
  • the individual molds In the event that the weight of the individual molds is not sufficient to hold them on the mold frame, they can be pressed against the upper side of the mold frame by spring-loaded pressure elements arranged on the metal distributor. When the metal distributor is lifted off the mold frame, the individual molds lie loosely on the mold frame and can be checked, cleaned or replaced.
  • the individual molds can be clamped to the mold frame by clamping elements arranged on the mold frame.
  • the mold frame 1 is designed as a box-shaped water pressure chamber which has openings 2, 4, 5 or 5, which are designed in accordance with the cross section of the individual molds, and is closed at the side.
  • the single mold 3 is designed as a two-part injection gap mold. It has an integrated, low water chamber 9, on its lower side 15 a ring of holes 10 as a water inlet opening and an oblique, annular spray gap 11 as a water outlet opening.
  • the mold parts 3a and 3b are screwed together (the screws are only indicated by their center lines).
  • the single mold 4 is designed as a two-part spray hole ring mold. It also has an integrated, low water chamber 9, on its lower side 15 a ring of holes 10 as a water inlet opening and an oblique spray hole ring 12 as a water outlet opening.
  • the mold parts 4a and 4b are also screwed together (the screws are only indicated by their center lines).
  • the single mold 5 is a one-piece spray hole ring mold. Your integrated, low water chamber 9 is formed in the casting process and opens down into an annular slot 13 as a water inlet opening. It also has an oblique spray hole rim 12 as a water outlet opening.
  • the annular slots 6 and perforated rings 7 of the mold frame 1, the perforated rings 10 of the individual molds 3 or 4 and the annular slot 13 of the individual mold 5 can be interrupted in the corner regions of a rectangular individual mold 14 in order to prevent excessive cooling of the ingot corner regions (FIG . 7).
  • annular groove 18 is formed on the side wall 17 of the depression 8 to catch the small amount of leakage water.
  • the leakage water is drained from the groove 18 through the drainage pipes 19 fastened in the mold frame 1 into the casting pit.
  • the weight of the individual molds 3, 4 or 5 is sufficient to hold them on the mold frame 1, because the cooling water pressure at the water transfer points is very low.
  • the individual molds 3, 4 or 5 are seated in the recesses 8 with a play of displacement (FIG. 1), it is advisable to press them against the upper side 16 of the mold frame for the time of casting.
  • spring-loaded pressure elements 20 are provided, which are attached to the distribution channel 22. The claws 21 of the pressure elements 20 hold the individual molds 3, 4 or 5 in place during the casting process.
  • the distributor channel 22 is lifted off the mold frame 1, and the individual molds 3, 4 or 5 are again loosely in the depressions 8.
  • seals 24 are inserted between the connection surfaces 15 and 16 of the individual molds 3, 4 or 5, or the mold frame 1, which are preferably located in grooves in the mold frame 1.
  • the individual molds 3, 4 or 5 are simultaneously clamped to the mold frame 1 by claws 21 and nuts 23.
  • the multiple mold according to the invention combines the advantages of the known gap or Punch ring molds as well as the well-known, externally sprinkled molds, without having their disadvantages, and also offers other advantages.
  • the individual molds of different formats can now be used in a single mold frame without the cooling of the mold used in each case being impaired.
  • the individual molds of different formats always have the same size and the same water inlet opening. They differ only in their clear cross-section and thus in the width of their ring-shaped water chamber. Regardless of their cross-section, they always have a precisely defined and directed water outlet opening that is adapted to the cross-section, namely a spray gap or a spray hole rim. Due to the special water flow, the water distribution within the mold frame and each individual mold is optimal, and therefore all bars can be cooled evenly.
  • the format change can be carried out quickly and easily.
  • the single mold used up to that point is simply removed from its seat, and a single mold of another format is inserted into the seat.
  • both the mold frame and the individual molds are simple.
  • the single molds consist of at most two simple parts, are cheap to manufacture, easy to clean and take up little space.
  • the field of application of the multiple mold according to the invention is of course not limited to conventional continuous casting with nozzles and floats. It can also be used as a component of multiple hot-head molds (hot-top process) or as a cooling device for multiple electromagnetic continuous casting molds.
