Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the melting plate has the same thickness everywhere and is melted completely by the melting material within a short time (DE-A-2 632 253).
  • non-meltable closure body from a meltable material, the melting point of which is preferably lower than the melting point of the cast metal and lower than the temperature of the material surrounding the opening. If a closure effect is to be maintained for a predetermined time, a closure body consisting of several parts is used, the upper part facing the melting material made of meltable material and the lower part of which has a supporting function and which can later be removed (CH -A-448 396).
  • the present invention has for its object to provide a device of the generic type, in which a certain part of the meltable melting plate melts before the remaining part of the melting plate melts.
  • This object is achieved according to the invention by the features in the characterizing part of claim 1.
  • This makes it possible to initially weld a smaller cross-section, determined by the dimensions of the target melting point, than the cross-section covered by the melting plate, and at least initially to allow a smaller flow of material, caused by the cross-section of the target melting point, to flow into the mold.
  • the thickness of the target melting point and the melting plate can be adapted to the respectively desired temperature of the molten material and the cross section of the mold.
  • a furnace jacket 1 is welded together from heavy plate and lined with refractory bricks 2 and a layer 3 of a refractory mass.
  • the holding furnace has a pouring opening 22 on one side.
  • the pouring opening 22 passes through a cast iron front plate 4 fastened to the furnace casing 1.
  • An intermediate flange 5 (FIG. 2) with a mold 6 and a cooler 7 associated therewith is fastened thereon.
  • a flange 8 is welded to the furnace jacket for attaching an inductor 9.
  • a removable cover 10 is arranged, which is filled with a refractory mass 11 and has a burner block 12 for receiving a burner, not shown.
  • a temperature measuring point 13 is provided, which has a thermocouple 14.
  • the position of the intermediate flange 5 on the front plate 4 is precisely determined by means of dowel pins.
  • the area between the mold 6 and the layer 3 covering the stones 2 is bridged by a feed hopper 17 surrounded by an insulating body 16.
  • the insulating body 16 consists of an insulating compound and the feed funnel 17 consists of a refractory compound.
  • the clear recesses are each the same.
  • a melting plate 25 is used, which fills the pouring opening 22 and is held by the feed hopper 17.
  • the melting plate 25 has a predetermined melting point 26 of reduced thickness on the underside.
  • the material of the melting plate 25, its thickness and the thickness of the target melting point is adapted to the temperatures and the cross sections of the mold 6, respectively, which have the molten material.
  • a seal 19 in the form of an asbestos plate or the like is provided between the front plate 4 and the intermediate flange 5.
  • the cooler 7 surrounding the mold 6 is releasably attached with its flange to a retaining ring 20 by means of screws, which in turn is also releasably attached to the intermediate flange 5 by means of screws.
  • To align the mold 7 slots can be provided on the mounting flange of the cooler. It is possible to arrange several molds 6 on the intermediate flange 5.
  • the pouring opening 22 is designed in such a way that no contaminants get caught in it when the holding furnace is being filled and these are carried along by the molten material exceeding the pouring opening 22.
  • the target melting point 26 and the melting plate 25 each melt after a predetermined time.
