Definitions

  • the invention relates to a device according to the preamble of claims 1 to 16 and a method according to claims 17 and 18.
  • Adjustable continuous casting molds for vertical casting machines are known. With these continuous casting machines, however, there are no sealing problems in the area between the storage container and the mold, which would be comparable to those of horizontal continuous casting machines for metals.
  • a horizontal continuous casting machine for metals which has a clamping device which is connected on the one hand to the mold and on the other hand directly to a liquid metal line, a device for controlling the contact pressure of the liquid metal line is provided on the mold to ensure a tight metal-impermeable joint. It is not known from this document to change the cross section of the mold. With regard to the sealing possibility, the device known from this document has the disadvantage that the holder which fixes the rigid mold at one end is supported at the other end on the liquid metal line. To absorb the forces between the liquid metal line and the storage container, the rigid mold is connected via a complex device, namely the foundation, base plate, support frame and displacement device. The large number of elements and the large number of external influences do not allow the short distances and exact force settings required in the area of the sealing surface in the case of an adjusting mold.
  • a casting stop means that solidified remnants remain in the mold and can only be removed with special effort.
  • JP-A-62 240 145 a horizontal continuous casting device for metals is described, in which the continuous casting mold in its passage cross-section can be changed and in which adjustment elements are provided with which the position of side plates can be adjusted, with at least one side plate being perpendicular to Center axis of the outflow opening is movable.
  • the invention had for its object to improve the adjustability of the mold and to provide a method and a device of an adjustable continuous casting mold for horizontal continuous casting machines, which enables a safe change in the passage cross section of the mold before, during and after the casting process in a structurally simple manner.
  • the change in position of the displaceable side surfaces is timed in such a way that the most heavily loaded sealing surface is the first to be relaxed in the area of the release ring.
  • the displacement force is applied in a pulsating manner.
  • adjusters can be used with energy-storing (e.g. springs) or self-locking (e.g. spindles) elements.
  • the horizontal continuous casting device only requires a small mold park, since the adjustable mold covers entire cross-sectional areas. Before casting, the "Thickness" or “Width” variation can be selected using the appropriate mold.
  • the adjustment mold according to the invention allows the mold not only to be adapted to a different casting quality, but also to a different casting speed. This adjustment is possible during the casting by adjusting the passage cross-section while adjusting the conicity even during the casting process. This is important, especially for the start and end of casting.
  • the process is particularly suitable for thin cast products (less than 50 mm thick) because the start-up process is defused. This is possible because, for safety reasons, a larger starting thickness can be selected during the starting process, which can be corrected again during the casting process. Only one start-up head is needed for different casting cross-sections. In addition, the process of filling the mold over time makes this process safer overall.
  • the already high level of tightness through the use of the proposed adjustment elements can also be increased by the shape of the sealing surfaces.
  • High sealing results are achieved in the configuration of the end face of the side plates as elements that can be compressed in the area of the sealing surface and have a high restoring force, as a result of the proposed lip-shaped configuration of the end faces.
  • Good results are also achieved by the combination of a straight end face and a seal that is operatively connected to it, e.g. B. a squeezable metallic seal.
  • a conical sealing surface of the release ring in the region of the displaceable side plate is proposed as a further advantageous seal.
  • the side plate is pressed against the "higher" conical part of the release ring depending on the predetermined relaxation.
  • Figure 1 shows the reservoir 10 with the outflow opening 11, in which the nozzle block 12 is arranged.
  • the releasing ring 20 Arranged on the nozzle block 12 in the outflow direction is the releasing ring 20, against which the continuous casting mold 30 (here broadside above 31 and broadside below 32) is based.
  • the continuous casting mold 30 forms the strand 60.
  • the base plate 50 is releasably attached to the storage container 10.
  • the adjusting elements 40 (perpendicular to the central axis 42 and in the direction of the central axis 43) are arranged between the base plate 50 and the continuous casting mold 30.
  • FIG. 2 shows a mold with four adjustable side walls 31 to 34 in the upper part.
  • the side plates 31 to 34 form the passage cross section A, which is discharged in the direction of the central axis I.
  • Each side wall 31 to 34 leans with its end face 38 against a neighboring wall and is held in this position by an adjusting element 41.
  • the adjustment elements 42 and 43 are provided for adjusting the side walls 31 to 34 perpendicular to the center axis and in the direction of the center axis.
  • FIG. 2 shows a continuous casting mold 30 in which three side walls 31, 32, 33 are intimately connected to form a U-shaped component and the side wall 34 is arranged to be adjustable.
  • the narrow side 34 is moved by the adjusting element 42.
  • the U-shaped component is moved on one leg (broad side 31) by the adjusting element 42, which is supported on the base plate 50.
  • the adjustment elements 43 serve for the non-positive connection of the side surfaces 31 to 34 to the release ring (not shown).
  • FIG. 3 shows a continuous casting mold 30 with two adjustable narrow sides 33 and 34.
  • the broad side 32 is locked on the foundation plate 50.
  • the broad side 31 is held non-positively against the side surfaces 33 and 34 by the adjusting elements 42.
  • the narrow sides 33 and 34 are changed in their position by the adjusting elements 42, which are supported on the base plate 50. All mold sides are pressed by adjusting elements 43 against the release ring (not shown).
  • view B-B is shown through the continuous casting mold.
  • the broad side 32 and the narrow sides 33 and 34 are pressed against the release ring 20 in the direction of the central axis I by the adjusting elements 43 supported on the base plate 50.
  • FIG. 4 shows a continuous casting mold 30 in which two side surfaces 31, 33 and 32, 34 are connected in an L-shape. Both L-shaped components 31, 33 and 32, 34 are mutually displaceable and thus change the passage cross-section A.
  • the adjustment elements 41, 42, 43 are provided, which are supported on the base plate 50.
  • a mold with L-shaped components is shown, in which an L-shaped component is fixed.
  • FIG. 5 shows with the view “C” a detail from the detail in FIG. 3, lower part.
  • the detail shows part of a mold side 33, 34 with the water guiding chamber 39.
  • the lip 36 is shown in the upper part of FIG. The lip 36 points in the direction of the release ring and at the same time in the direction of the central axis I.
  • the end face 35 leans against the release ring 20 with a part which faces the center axis I.
  • the part of the end face 35 which faces away from the center axis is spaced apart from the release ring.
  • a squeezable sealing element 37 is arranged in the space between the detaching ring 20 and the end face 35. The sealing element 37 ensures a higher tightness of the sealing surface.
  • FIGS. 6 and 7 each show two sections through the detachment ring 20 and the continuous casting mold 30 with the strand 60, namely the broad sides 31, 32 in the upper part of the picture and the narrow side 33 in the lower part of the picture.
  • the side surface 21 of the release ring 20 is perpendicular to the outflow opening 11.
  • the broad sides lean against the outwardly facing side surface 21 of the detachment ring 20 approximately parallel to the outflow opening 11.
  • the narrow side 33 has the conical side surface 22 as the sealing surface.
  • the wall thickness of the detaching ring 20 increases as the distance from the outflow opening 11 increases.
