Definitions

  • the invention relates to a horizontal continuous casting installation, in particular for continuous steel casting, with a distributor vessel for receiving the melt and at least one continuous mold attached to the distributor vessel, the distributor vessel, together with the mold, being able to be brought into or out of this position in a position aligned with a stationary strand guide path is movable away.
  • the mold forms a unit with the vertgiler (cf. Stahl und Eisen, 101, 1961, “Status of the development of horizontal continuous casting of stainless steel at Böhler AG”; “Horizontal continuous casting plants for the fully continuous production of press bolts from copper and copper alloys “from metal science and technology, 33rd year, issue 12).
  • the distributor vessel, to which the mold is attached can usually be moved or swiveled on rails transversely to the longitudinal axis of the continuous casting installation, so that it and the mold can be brought into or out of this position from the outside of the installation into a position aligned with a stationary strand guide path the maintenance or replacement of the vessel and / or the mold is movable.
  • the strand In the case of horizontal continuous casting machines, the strand is withdrawn from the mold discontinuously, with gradual extraction being used. After each pulling step, the strand is pushed back into the mold by a fraction of the length of a pulling step.
  • This method of operation prevents the strand shell from getting caught on the mold attached to the distributor vessel.
  • the mold can partially oscillate along with the strand, so that for this reason too, the relative movement between the strand shell and the mold when pulling and pushing back does not exactly produce the desired one Has size.
  • the invention aims to avoid these difficulties and disadvantages and has as its object to create a continuous casting installation in which the relative movement between the continuous shell and the mold has exactly the desired profile and the desired size.
  • the continuous mold can be fixed without play in the longitudinal direction of its mold cavity relative to the foundation.
  • the mold can expediently be fixed relative to the foundation by means of at least one wedge which can be inserted between a support plate on the mold and a stationary support plate.
  • a wedge here has the particular advantage that the mold, regardless of its position in space, .u.zw. Regardless of whether it is closer or farther away from the stationary strand guide (depending on the play of the chassis of the distribution vessel), it can be fixed to the stationary support surface.
  • the fixed support plate is advantageously directed at right angles to the strand path axis, whereas the support plate on the mold is arranged inclined to the strand path axis, which results in a particularly favorable introduction of force into the mold.
  • the support plate on the mold and the stationary support plate are of split design, the parts of the support plates each being symmetrical to the strand axis.
  • the support plate on the mold is as small as possible, i.e. dimensioned according to the maximum permissible surface pressure.
  • the wedge is advantageously also designed to be divided, each part of the wedge being able to be brought into contact with a part of the support plate of the mold and a part of the stationary support plate independently of the other part.
  • a simple, quickly detachable connection between the mold and the fixed support surface is characterized in that the fixed support plate is arranged on a bracket fastened to the foundation, the console being connectable to the mold by means of at least one tie rod arranged in the direction of the strand path axis, and wherein furthermore, the tie rod is pivotally attached to the console.
  • a further preferred embodiment is characterized in that the mold can be tensioned relative to the foundation by means of a rotating wedge, in particular an eccentric cam.
  • Two counter-rotating wedges are advantageously provided, between which a support plate mounted on the mold can be inserted, both rotary wedges being clampable against the support plate.
  • FIG. 1 shows a partially sectioned side view of a horizontal continuous casting plant
  • FIG. 2 shows a detail of this plant on an enlarged scale
  • FIG. 3 shows a view according to arrow 111 in FIG. 2.
  • 4 is another Embodiment of a horizontal caster according to the invention illustrated.
  • FIG. 5 shows a third embodiment in a representation analogous to FIG. 2.
  • FIG. 6 is a view in the direction of arrow VI of FIG. 5.
  • a continuous continuous casting mold 4 is fastened to an intermediate vessel 2 which can be moved horizontally on rails 1 in the region of the pouring opening 3 by means of screws 5.
  • the continuous casting mold 4 has a hollow frame 6 through which a coolant flows and which is provided with flange plates 7 on the inlet and outlet sides of the mold.
  • the inlet-side flange plate is attached to the intermediate vessel 2, two aftercoolers 8 are mounted on the outlet-side flange plate.
  • a bracket 10 is mounted on the foundation, which has two support plates 11, 12 located laterally at a distance from the strand axis 13 and thus allows a strand to pass through.
  • the ends of these support plates 16 lying in the strand pull-out direction 14 17 are beveled in a wedge shape and each carry a support plate 19 at the level of the strand path axis 13.
  • a tie rod 22 is pivotally mounted on the outside, which can be pivoted from a waiting position, in which it is held by means of a stop 23, into a position parallel to the strand axis 13.
  • a nut 24 is provided, which engages behind a tensioning tab 25 of the support plates 16, 17 when the tie rod is pivoted toward the mold. By tightening these nuts 24, the mold 4 can be fixed on the console.
  • the wedge angle 26 of the wedge is chosen so small that self-locking occurs, i.e. that the wedge cannot be released by forces acting in the direction of the strand axis 13.
  • the support surface for the wedge 21 on the bracket 10 is larger than the wedge itself and is arranged vertically and the support plate 19 for the wedge 21 on the mold side is made as small as possible (corresponding to the maximum permissible surface pressure) and is provided at the level of the strand path axis, a central one is provided Force introduction of the supporting forces into the mold 4, regardless of the elevation and axial inclination of the mold 4 to the console 10, is ensured.
  • the wedge 21 is appropriately divided, i.e. a separate wedge piece is provided for each pair of support plates 16, 11 and 17, 12, as a result of which bending stresses are kept away from the mold construction. It is also possible to design the support surface of the wedge on the mold side as well as the fixed support surface of the wedge on the console divided in the vertical direction, the parts of the support surfaces each being symmetrical to the strand axis.
  • the strand guide track is represented by rollers 27, a driver pair 2 being provided in the strand guide track, with which the strand is pulled out of the mold in an oscillating manner.
  • the bracket 10 is not mounted on the foundation 9, but is only supported on the foundation in the vertical direction. In the horizontal direction, i.e. in the direction of the strand axis 13, the bracket 10 is fixed by means of struts 29 on the frame 30 carrying the driver pair 28.
  • the embodiment according to FIGS. 5 and 6 has two wedges designed as rotary wedges 31 which are pivotably mounted about an axis 32 on a stationary housing 33.
  • the rotary wedges can be pressed against a support plate 35 of the mold 4 by means of a self-locking worm gear 34.
  • a gear 36 with a motor 37 is provided for each rotary wedge.
  • the rotary wedges act against each other, and the support plate 35, against which they act, lies between the rotary wedges 31.
  • the rotary wedges are expediently arranged such that the lines of contact 38 of the rotary wedges the support plate of the mold are at the level of the strand axis, as illustrated in FIG. 5. It is advantageous if two further rotary wedges, as seen from above, are arranged symmetrically to the strand path axis, so that bending stresses on the mold construction are largely avoided.
