Definitions

  • the invention relates to a casting wheel with a casting ring rotatably mounted on the inside on rollers for a strip casting machine.
  • the invention has for its object to provide a casting wheel of the type mentioned, in which the position of the casting ring in the pouring position remains unchanged even during the casting operation.
  • roller (s) in the region of the sprue position on one or more support element (s) radially rigid and the opposite roller (s) are supported on one or more additional support element (s) in a radially adjustable manner.
  • the roller (s) and / or the respectively assigned support element can be elastically mounted for the radial adjustability of the roller (s).
  • the support element can also be acted upon hydraulically, while the rollers are mounted elastically.
  • each roller supported on the further support element in a radially adjustable manner can be pivoted to the axis of the casting ring.
  • the support elements are preferably arranged on a common rigid support axis. To the rollers with their Bring support elements into the sprue position, the support axis should be rotatable.
  • a roller is sufficient to support the pouring ring in the area of the sprue position.
  • at least two rollers which are offset with respect to one another in the circumferential direction of the casting ring are preferably provided.
  • the rollers do not need to have a jacket extending over the entire width of the race, but can be composed of a plurality of impellers which are arranged at a distance from one another. So that the wheels can be equipped with casting rings of different widths, it is provided according to a further embodiment of the invention that the distance between the wheels of each roller is adjustable.
  • the radially adjustable castors each consist of several impellers, it is advantageous if they can be adjusted independently of one another in order to be able to be adapted to a conical deformation of the race. This can be achieved in various ways, for example in that each impeller is assigned its own support element or in that the impellers of a roller are mounted on a common pivotable axis.
  • rollers or wheels can have the same diameter. However, it can be useful in certain cases if the impellers have a different diameter.
  • At least one guide track for the roller provided in the region of the sprue position can be provided on the inside be provided.
  • a guide acting externally on the casting ring can also be provided.
  • the rollers are preferably freely rotatable and the casting ring is driven externally. In terms of design, this can be achieved with a transmission element arranged on the end face and a drive wheel carried by it. This type of drive is much simpler in comparison to driven rollers and reduces the risk of the casting ring slipping against the drive.
  • the casting ring can be closed on both ends by a plate, the support shaft being sealed off on the bushing by the plate.
  • coolant can be selectively supplied to and removed from the interior of the interior thus formed. This can e.g. happen in such a way that the coolant spray nozzles distributed in the upper area of the casting wheel are sprayed onto the inside of the casting ring with nozzles distributed and are collected in the lower area of the inner cavity and are discharged from here via a line. The coolant therefore remains inside the casting wheel.
  • the special advantages of the invention in addition to the guaranteed constant maintenance of the passage gap formed by the casting ring and a casting nozzle or a tundish or a second casting wheel, and the improved drive of the casting ring, are the easy interchangeability of the casting ring and the possibility of surface treatment of the casting ring in the strip casting machine by means of a Twisting device, which in the pouring position is brought or in the position of which the pouring ring is brought by turning the rigid support.
  • a belt casting machine consists of a casting vessel 1, 2, in which molten metal is contained, and of two casting wheels 3-6, which can have different or the same diameter.
  • the casting wheel 3 which is smaller in diameter, can be a massive roller.
  • the casting wheels 4-6 have the structure according to the invention, which will be described in detail below.
  • the two casting wheels 3-6 close the outlet of the casting vessel except for a passage gap, through which molten metal forms a band 7,8 can leak.
  • the casting wheels 3-6 are preferably cooled so that the band 7, 8 leaving the casting wheels 3-6 has solidified.
  • a tundish or a casting nozzle can also be assigned to the casting wheel 4 and form the exit gap for the molten metal with it.
  • a pouring ring 10 forms a passage gap for molten metal, which is applied to the outside of the pouring ring 10 and solidifies on rotation of the pouring ring 10 on it, so that it can be pulled off it as a band.
  • the pouring ring 10 is supported on the inside on two wheels 11a, 11b forming rollers. This roller 11a, 11b is rigidly supported in the radial direction of the casting ring 10 by a support element 12 such that the outlet gap between the casting ring 10 and the tundish or the pouring nozzle 9 remains unchanged.
  • a roller 13a, 13b Opposed to the roller 11a, 11b is a roller 13a, 13b in the form of two wheels 13a, 13b, on which the casting ring 10 is also supported on the inside.
  • This roller 13a, 13b is supported in a radially adjustable manner on a preferably hydraulic support element 14 and, for example, can also be pivoted against the force of a spring 15.
  • Fig. 1 shows on the left the condition of the cold pouring ring 10 and on the right the condition of the warm pouring ring 10, which has expanded on one side due to the one-sided exposure to the molten metal.
  • the radially adjustable and pivotable impellers 13a, 13b absorb deformation, so that the position of the casting ring 10 in the region of the pouring position of the tundish 9 is held in contact with the rollers 11a, 11b, so that the outlet gap does not remain despite the expansion of the casting ring 10 changes.
  • This basic structure can be implemented constructively, as shown in the exemplary embodiments 2 to 7.
  • the casting ring 20, 30, 40, 50 carries a drive element 20b, 30b, 40b, 50b on at least one end face via a driving plate 20a, 30a, 40a, 50a, via which the casting ring 20, 30, 40, 50 can be driven externally is.
  • each casting wheel has a rigid support axle 26, 36, 46, 56 on which upper support elements 22, 24, 32, 34a, 34b, 42, 44, 52, 54 impellers 21, 22, 31a, 31b, 33a, 33b, 41a-41c, 43a-43c, 51a-51c, 53 are supported.
  • the casting rings 20, 30, 40, 50 are supported and supported on the inside at least at two, but preferably at three or more, locations.
  • the wheels 21, 31a, 31b, 41a, 41b, 41c, 51a, 51b, 51c, 51d are rigidly arranged on the rigid support shaft 26, 36, 46, 56 via their support elements 22, 32, 42, 52, while the opposite wheels 23, 33a, 33b, 43a, 43b, 43c, 53 can preferably be adjusted hydraulically radially via their support elements 24, 34a, 34b, 44.54.
  • a radially adjustable roller is formed by a plurality of wheels 33a, 33b, 43a, 43b, 43c, the wheels 33a, 33b, 43a, 43b, 43c are independently radially adjustable. According to FIG. 3, this can be achieved by individual support elements 34a, 34b or, according to FIG. 4, by a pivot bearing 47.
  • a guide track 29, 39 a, 49 a, 59 in the form of an annular groove is preferably provided in the inside of each casting ring 20, 30, 40, 50 engages at least one set of rollers 21,23,31a, 33a, 41a, 41c, 43a, 43c. If a plurality of rollers, in particular those that are adjustable in their mutual spacing, are arranged next to one another, a second recess 39b, 49b can be provided, which, however, has no guiding functions and is therefore wider than the associated impeller 31b.
  • the casting ring 20, 30, 40, 50 can also be guided axially by means of external guide elements.
  • impellers can be arranged next to one another on the rigid support axis 26, 36, 46, 56, but the impellers can also be arranged such that their spacing from one another is adjustable, as in the initial example in FIG. 3 by the double arrow of the impeller 31b is indicated.
  • the end faces of the casting ring 20, 30, 40, 50 are closed by two plates 20a, 20a *, 30a, 30a *, 40a, 40a *, 50a, 50a *, of which the first plate simultaneously serves as the driving plate for the drive elements, for example the V-belt pulley, forms.
  • a seal can be provided on the passage of the support shaft 26, 36, 46, 56 through the plate 20a, 30a, 40a, 50a.
  • a targeted supply of the coolant into the cavity thus formed takes place via spray nozzles distributed in the upper region of the casting wheel and distributed in the circumferential direction.
  • the double-sided plates 20a, 20a *, 30a, 30a *, 40a, 40a *, 50a, 50a * prevent coolant from escaping to the outside.
  • the coolant is collected in the lower area of the cooling wheel and discharged from here via lines.
