Definitions

  • the invention relates to a mold for casting metals, a method for producing such a mold, and a use of this mold.
  • the choice of material, coating, dimensions and temperature of the mold significantly influences the rate of solidification and thus the quality of the casting.
  • the rate of solidification can be controlled before or during casting by regulating the thickness of the insulating coating and the intensity of the mold cooling. This regulation takes place according to the experience of the founder or according to the periodic or permanent determination of the heat balance of the mold.
  • an accurate determination of the heat balance that is responsive to changes requires undisturbed temperature measurements in places that are often difficult to access and cannot be carried out satisfactorily in the conventional molds.
  • the inventor has therefore set himself the task of developing a mold and a method for its production, in which the heat flow can be determined quickly and in an unadulterated manner through its surface facing the melt.
  • thermocouple forming Drumble at least one point of the mold in each case two - te are so embedded in the mold, that the first contact point connected to the two loop Wires of the thermocouple lies outside the mold on the side facing away from the melt and that the other ends of the two wires are separated from the surface of the mold facing the melt only by a metallic cover layer which is at most 100 ⁇ m thick and connects these wire ends.
  • the invention When producing such a mold, the invention provides for the metallic cover layer to be applied galvanically to the wire ends.
  • the processes of plasma spraying, vapor deposition or sputtering are provided as a further type of production of the metallic cover layer.
  • This cover layer is advantageously made of silver.
  • thermocouples in the manner according to the invention allow temperature measurements directly below the surface, on the basis of which an exact heat balance image of the mold can be created, in particular if thermocouples in the manner according to the invention are attached to different locations of the mold. Thanks to the low mass of the elements and thanks to the exclusively metallic connections between the mold surface and the wire connection point, the short response time of the thermocouples allows up to 5000 individual measurements per second. With this amount and speed of information, mold cooling can be regulated efficiently. Likewise, the thickness of the heat-insulating layer can be regulated, for example, by metering the casting powder to be applied to the mold surface.
  • a mold has proven to be particularly expedient, which has at least one continuous cylindrical bore which perpendicularly penetrates the surface of the mold facing the melt.
  • a body consisting essentially of the same substance as the mold is inserted seamlessly into this bore.
  • the side facing the melt surface of this K OER pers constitutes, pierced through the bore, a mold surface continued steadily.
  • the body has an axial bore in which the thermocouple wires are insulated.
  • the above-mentioned cover layer connecting the wire ends forms part of the surface of the body used.
  • the heat flow inside the mold is only very slightly influenced by this body. Mold repairs are made easier thanks to the easy removability of this body.
  • the mold according to the invention can be used in all metal casting processes, such as continuous casting and molding.
  • the mold is particularly advantageously used in a continuously operating strip caster, in particular for the casting of aluminum strips, with moving, cooled caterpillars.
  • Such a strip caster requires rapid measurements due to the high casting speed.
  • the volume-related large surface area of the cast strip is not affected by the use of the mold according to the invention.
  • the copper mold 9 of Figure 1 is provided as a continuous strip casting plant with a part Kokillenbarren R au- penkokillen (CASTRR II). Perpendicular to its surface 1, which faces the melt (not shown), the mold 9 has a continuous cylindrical bore 10, into which a copper body 2 of 10 mm diameter is inserted seamlessly in such a way that its surface 11 and surface 1 are in the same plane lie.
  • the body 2 has an axial bore 3, which is closed at one end by a silver cover layer 4.
  • the cover layer 4 is part of the surface 11.
  • the axial bore 3 is covered by an aluminum oxide plate 5.
  • FIG. 2 In the axial bore 3, two 100 um thick conductor wires made of Chromel 6 and Alumel 7 are drawn in (FIG. 2), between which and against the copper cladding of the body 2, insulating layers 8 made of 10 um thick mica are arranged.
  • the conductors 6 and 7 are connected to one another via the 50 ⁇ m (d) thick, galvanically applied layer 4 and penetrate the aluminum oxide plate 5 at the other end.
  • the continuous belt caster has several mold bars of the mold 9 type on both tracks.
