Definitions

  • the invention relates to a mold device for producing endless strands of metal, in particular of steel slabs, with copper plates for the broad sides of the mold, which can be cooled Support the support plates with between the broad sides pinchable narrow sides and with one with the Support plates connected oscillation device.
  • the mold device known from this document has no electromagnetic device on.
  • DE 31 12 039 C2 is a continuous casting mold known with stirring coil for rectangular strands, in the four Support plates clamped together and assembled Condition of two braced by draw bolts Sides are held in which the Stirring devices are provided.
  • this stirring device designed for continuous steel casting molds is a stirring coil chamber on one the upper part of the cooling box.
  • this stirring device is the stirring winding in one piece with the mounting plate in the cooler freely installable and removable.
  • the mounting plate is used here as a lid to close the opening of the Stirring winding chamber and forms at the same time Back wall.
  • a mold device is known from EP 0 577 831 A1 known for producing slabs, with copper plates for the broad sides of the mold, which can be cooled Support the support plates with between the broad sides pinchable narrow sides and with one with the Support plates, connected oscillation device. Andes outer rarities of the support plates are water boxes arranged that leave a central opening in the - When assembling the mold device - from core and coil formed electromagnetic components are used. To remove the mold, they must be in operation electromagnetic ones supported on supporting frames Components are removed together with the mold.
  • WO 94/16844 is a mold device known in which also electromagnetic components are provided. But these have split cores, so that part of the keme when expanding the mold be expanded with this as they are in the water tanks are integrated.
  • This structure of the stirring chamber is complex Way when changing the cooling elements always dismantle the stirring coil.
  • the invention pursues the goal of a mold device according to the preamble of claim 1 to create a compact and low-torsion Has structure that is easy to change and that without increasing by the oscillation device moving mass using an electromagnetic Component.
  • the support plates are trough-shaped educated. This configuration does not only high rigidity in the copper Broad sides of the mold supporting support plates reached, it is also used in addition to the targeted guidance of the cooling medium created a freely usable space in which a electromagnetic stirring or braking device can be introduced is.
  • the possibility is opened regardless of the oscillating mass of the mold the electromagnetic device vertically to move to the strand conveying direction. hereby the possibility is opened with extremely simple means the support plates for disassembly from the mold release. In addition, the facility arbitrarily and without any further effort with or can be operated without a stirrer or braking device.
  • the electromagnetic device can affect the oscillating Crowds the electromagnetic device are moved parallel to the strand conveying direction an optimal setting even during operation to reach the stirring or braking device.
  • the trough-shaped structure of the support plates draws is characterized by a special rigidity. For further Increasing this stiffness are in the free space Bridges or ribs can be inserted.
  • the support plates have in their design with the overhangs supported on the yokes the constructive advantage, particularly simple to be put together. This will not only Installation time minimized, the possibility is also opened Pre-assemble the mold with simple means.
  • the fixation of the electromagnetic device as a stirring coil happens in a simple manner characterized in that up to a drive of the coil core is moved to the bottom of the trough.
  • the coil core surrounding coil is also in the direction of the support plate procedure and and just before the outer edge of the Support plate stopped. For safe positioning the coil core is clamped.
  • the individual coil cores are supported a common coil yoke, which is coil yoke designed in a ring and around the support plates led around.
  • the individual support plates have a head end Cantilevers, each on supporting yokes support. These support yokes are designed so that that they include the narrow side adjustment and in a simple way without any hindrance together with the support plate they carry the system are removable.
  • the support yoke water guides have to the water supply or. removal with to connect the support plates.
  • the support yokes elastic elements provided a horizontal adjustment of the Broad sides to each other without obstructing the water flow enable.
  • the support yokes are constructively so designed to hold the support plates and theirs enable horizontal fixation to each other.
  • FIG. 1 shows a section through the mold device, namely A, B of Figure 2.
  • the figure is a support frame 31 with its longitudinal extension and a support frame 33 with its transverse extent shown.
  • the support frame 31, 33 is based on the mold table 39 from.
  • a narrow side bracket 14 is appropriate.
  • This drive-side narrow side bracket 14 is connected to an oscillator 41 which in turn on the support frame 33, which in turn stands on the mold table 39.
  • the narrow side bracket is - not here further illustrated - with the narrow side 13 in connection.
  • the narrow side 13 is between the broad sides 11 pinched.
  • the broad sides 11 are on support plates 21 attached.
  • a coolant supply 51 is provided via an elastic element 54 with one in a support yoke 36 introduced water guide 53 in connection stands.
  • the elastic element 54 is like this designed that it is the oscillatory movement of the The mold can hold and safely the cooling medium leads.
  • On the support yoke support 36 is based in the area the water guide 53 from a support yoke 35, which over a flexible element 57 connected to the support plate 21 is.
  • the support yoke 35 is in its central area fork-shaped and encompasses the narrow side bracket 14.
  • the two-armed support yoke has both ends Arms 37 on which broadside brackets 38 are provided with which the support plates 21 in their assignment to each other with regard to the strand width are adjustable.
  • the support plate 21, on the outside of which Broadside 11 is attached, is trough-shaped.
  • the opening of which from the broad sides 11 has turned away, protrudes against the trough bottom 24 leaning against a coil core 65 of a stirring coil 61
  • Coil core 65 is encompassed by a coil 67 which is up to in the vicinity of the outer wall 27 of the support plate 21 feasible is.
  • the coil core 65 is supported on a coil yoke 66, which is designed as a ring.
  • the Coil yoke 66 is adjustable in height.
  • the coil core 65 is on a drive 64 connected and can be moved horizontally so far, that he headed out of the trough space 23 the Support plate 21 can be pulled out. To fix the a respective clamping device 63 is provided.
  • FIG. 2 shows the top view of the mold device.
  • the broad sides 11 provided support plates 21 shown between which the narrow sides 13 are clamped are.
  • the narrow sides 13 are via a narrow side bracket 16, over gripping elements 15 and over Narrow side brackets 14 on which spring elements 44 are attached to the support frame 31.
  • a transmission linkage is on the support frame 31 43 rotatably supported, one arm with one oscillation device 41 and the other Arm is connected to the narrow side bracket 14.
  • the narrow side bracket 14 is also coupled with a narrow side drive 17.
  • the support yoke is supported on the support yoke support 36 35 from.
  • the support yoke 35 has arms 37 which over Width brackets 38 fix the support plates 21.
  • the left part of Figure 2 shows a partial section through the support plate 21.
  • the coil core 65 is one Gripped coil 67.
  • the coil 67 close to the outer edge 27 of the Support plate 21.
