Definitions

  • the invention relates to a mold for the continuous casting of billets, slabs or billets according to the preamble of claim 1.
  • Continuous casting molds are known to be subject to significant thermal stresses during operation due to the solidified in Kokillenhohlraum liquid metal. The latter consequently cause thermal expansions of the mold walls and thus lead to deformations of the precisely produced mold cavity. Particularly undesirable are deformations transverse to the casting direction, because they change the important for the solidification Kokillenkonizmaschine. It is therefore necessary to take special measures to stabilize the mold walls in their position.
  • EP-A-1 468 760 is known to arrange the mold cavity forming mold tube made of copper a support jacket on which the mold tube is supported on extending in its longitudinal direction and distributed over the circumference support profiles.
  • the mold tube is positively connected to the support jacket via longitudinally extending connection profiles, wherein between the mold tube and the support jacket cooling channels are arranged for guiding cooling water, which are limited by the support profiles and / or the connection profiles.
  • the connection profiles are formed, for example, as dovetail or T-profiles, which engage in corresponding grooves of the support jacket. Inserted into the grooves they are in the longitudinal direction of the mold. This assembly is not always easy because it causes friction between the mold walls and provided the support shell sealing elements.
  • the mold tube walls are each not only held in the direction perpendicular to the casting axis, but also prevented from thermal expansion in the wall or support plane, transverse to the casting axis. The latter can lead to tensions and permanent deformations and fatigue cracks of the mold tube.
  • EP-A-1 025 929 is a mold plate of a mold of copper provided with milled cooling channels.
  • the webs between the Ktihlkanälen represent support profiles relative to the adapter plate, which limit cooling channels for guiding cooling water.
  • C-shaped mounting rails are screwed onto the mold plate by means of fastening screws on widened webs between the cooling channels.
  • the cooling can not be uniform, especially since the C-krnügen mounting rails are screwed on widened webs between cooling channels of the copper plate with mounting screws.
  • the present invention has for its object to provide a mold of the type mentioned above, which has a high dimensional stability in the casting operation, and in which nevertheless caused by thermal expansion of the mold walls deformations can be largely avoided.
  • connection profiles are in each case designed as two profiled strips protruding inwards from the outer circumference of the mold tube and projecting inwardly from the inner circumference of the support casing, which interlock in such a way that a clearance is present in the circumferential direction of the mold.
  • a mold 1 for continuous casting of rectangular cross-section blooms, slabs or billets which has a mold tube 2 made of copper, which forms a mold cavity 3, and a surrounding the mold tube 2 support jacket 4.
  • the support shell 4 is composed of four support plates 5, 5 ', which are connected to each other by means of screws 6.
  • cooling channels 10 are provided for guiding cooling water, which form part of a water circulation cooling for the copper pipe, form ferrohr, and which are distributed over the entire circumference and substantially over the entire length of the mold tube 2 (see, in particular Fig. 2 and 4 ).
  • the support plates 5, 5 ' are provided in the upper and in the lower region with connected to the cooling channels 10 inlets and outlets 11, 12 for the cooling water.
  • the cooling channels 10 are embedded in the outer peripheral surface of the mold tube 2, for example milled.
  • the mold tube 2 is supported, on the one hand, by supporting profiles 15 extending in the longitudinal direction L and distributed over the circumference on the support jacket 4 or on the support plates 5, 5 ', and on the other hand is in contact with these support plates 5, 5' via connecting profiles 20 extending in the longitudinal direction in a detachable, positive connection.
  • the cooling channels 10 are bounded laterally by the support profiles 15 and / or the connection profiles 20.
  • connection profiles 20 are designed in each case as two profiled strips 21, 22 protruding inwardly from the outer circumference of the mold tube 2 and projecting inwards from the inner circumference of the support jacket 4. They are distributed over the respective Kokillenseite, wherein their number per page depends on the mold size.
  • the cross-sectionally rectangular mold 1 are for example according to Fig. 2 the wider support plates 5, each with four and the narrower support plates 5 ', each equipped with two connecting profiles 20.
  • the profiled strips 21, 22 are preferably nose-shaped in cross-section (as described below with reference to FIG Fig. 8a, 8b and 9a, 9b will be described) and interlock such that in the circumferential direction of the mold 1 a game is present.
  • the mold walls are in the on the held the support plates 5, 5 'adjacent position in the direction perpendicular to the casting axis, but it is possible due to thermal expansion mutual displacement along the mold wall possible, especially in Kokillenlnaturescardi L, but also in the context of the proposed game across it, in the circumferential direction of mold.
  • the mold tube 2 is held in its corner regions with a corresponding clearance relative to the support jacket 4.
  • Each of the support plates 5, 5 ' is advantageously equipped in its peripheral region with a cooling zone sealing the sealing ring 23, 23', in a Fig. 5 showing the support plate 5, shown channel 24 is inserted.
  • smaller mold 1 'square cross-section is only one of two interlocking profile strips existing connection profile 20' per mold side (and a plurality of support profiles 15 ') are present.
  • the connecting profiles 20 'connecting the mold tube 2' to the support jacket 4 ' are each arranged in the middle region of the respective mold wall.
  • FIGS. 6 and 7a . 7b, 7c If the respective support plate 5 "during assembly must be moved laterally relative to the Kokillenrohrwand until the engagement of the profile strips 21", 22 ".Also in the presence of sealing rings, the assembly is much easier than in the case of EP-B1-1 468 760 known molds, the lateral displacement in the novel mold is not to be compared in size with the longitudinal displacement during assembly according to the EP-B1-1 468 760 , In addition, the respective support plate 5 "can be set slightly inclined until it engages, thereby avoiding the friction on the sealing ring.
  • FIG. 8a, 8b and 9a, 9b Particularly advantageous cross-sectional shapes of the profile strips 21, 22 are made Fig. 8a, 8b and 9a, 9b seen.
  • the cross-sectional nose-shaped profiled strips 21, 22 project by an amount a from a base surface 27 or 28 of the mold tube 2 and the support plate 5, respectively.
  • the profile strip 21 of the Ko-21 of the mold tube 2 has a support surface 29, with which it rests in the assembled state on the base surface 28 of the support plate 5 and vice versa, the support plate 5 comes with a support surface 30 on the base 27 of the mold tube 2 to the plant.
  • the profiled strips 21, 22 each have a directed in the circumferential direction of the mold, rounded nose 31 and 32 with a radius r 1 , which is engaged by a likewise rounded, the nose in the circumferential direction opposite recess 33 and 34 with a radius r 2 ,
  • the Radis r 2 of the recesses 33, 34 is slightly larger than the radius r 1 of the two lugs 31, 32.
  • the nose engages the one in the recess of the other profile strip, with a lateral clearance of, for example, ⁇ 0.1 mm, which results from the difference between the two radii r 1 , r 2 , so that in the context of this game, a thermal expansion caused by mutual displacement along the mold wall in the circumferential direction of the mold can take place.
  • the mold size is crucial. For larger molds, a larger game must be guaranteed.
  • a possible cross-sectional shape of the nose-shaped profiled strips 21, 22 for larger molds is in Fig. 9a, 9b shown, where the nose 31 'and 32' of a profile strip 21 and 22, respectively in the recess 34 'and 33' of the other profile strip 22 and 21 with a larger game in the circumferential direction Richrich can intervene.
  • mold tube 2 or 2 'or 2 " it is also possible and quite usual to assemble the mold cavity forming the mold cavity as a plate mold with individual copper plates or otherwise shaped mold tube walls associated with a plurality of support plates which form the support shell around the plate mold around.
  • Fig. 10 shows as an example a mold plate 42 a plate mold for continuous casting of thin slabs.
  • the long sides of such molds are 1 to 2 m and the narrow sides only 50 to 10 mm wide.
  • the long-side mold plates 42 are provided in the upper region with a bulge 50 for the dip tube, ie the mold tube wall is not straight everywhere.
  • the mold plate 42 associated with the support plate 45 is provided on the inside with a corresponding recess 51.
  • the cooling channels 10 are provided, which are bounded by the support profiles 10 and / or the connection profiles 20.
  • the connecting profiles 20 are again designed as two interlocking profiled strips 21, 22 with lugs 31, 32 which engage in the circumferential direction of the chill and intermesh with play.
  • the bulge 50 and the recess 51 and the lugs 31, 32 are directed obliquely, parallel to the Kokilleninnen Chemistry 50 a, 50 b.
  • FIG. 5 illustrates a copper mold tube wall 52 of a plate mold for continuous casting of double T pre-profiles, which has a web part 52a, two flange parts 52b, and an oblique part 52c connecting the web part 52a to the respective flange part 52b.
  • the web portion 52a is associated with a support plate 55a.
  • the flange 52b are each equipped with a support plate 55b. Between the support plate 55a for the web portion 52a and the support plate 55b for the flange portions 52b, a support plate 55c extending along the inclined portions 52c is disposed and overlapped by the adjacent support plates 55a, 55b.
