    The invention relates to a device for continuous casting with a revolving mold, which is provided with at least one rotating mold.
    With the strand to be cast mitlaufende molds not only have molds in the form of two rotating plate chains with form elements that complement each other to form a cross-section of the cast strand defining, circumferentially closed mold space, but also molds with a circumferential, substantially horizontal steel strip on which is poured for the continuous casting of metal strips the molten metal. The lateral outflow of molten metal is prevented by lateral block chains of copper, resulting in difficulties in sealing between the steel strip and the block chains, because there is a risk that the thin steel strip under the high temperature load on the one hand by the molten metal and on the other hand by the spray water cooling warps, which is required to solidify the strip-shaped strand during its promotion on the rotating steel strip. The associated thermo-mechanical stress of such molds is therefore very large and leads to relatively short service life.
    The invention is therefore an object of the invention to provide molds whose molds can be acted upon with a spray water cooling, without running the risk of having to accept a thermal overload and thus an unacceptable deformation of the molds in purchasing. 2/11 2
    Starting from a device for continuous casting of the type described above, the invention solves the problem set by the fact that the rotating mold has a plate chain of individual mutually articulated plates, which are composed of the outer peripheral shape of the strand sections determining shell molds made of copper and steel straps which form along the joints between the shell molds, mutually hingedly connected legs that the shell molds have on opposing abutment surfaces a groove and a groove engaging in the groove.
    The replacement of, for example, a steel strip with a plate chain, which forms copper mold shells as mold elements, initially has the advantage that no separate block chains or the like must be used for laterally guiding the molten metal poured onto the shell molds guided in the horizontal direction, because the Shapeshells themselves form a corresponding side wall. The formation of the shell molds made of copper as a good conductor of heat allows intensive cooling of cast onto the mold shells strand, the strength of the plates of the plate chain is achieved by running along the joints between the shell molds, hinged together legs of the steel support, in the conventional Art can be supported on guide rails, for example via rollers. The exposure of the mold shells made of copper with water spray for intensive cooling of the cast strand is freely possible between the legs of the steel beam. However, it must be ensured that no splash water gets to the molten metal. For this reason, the joints between the shell molds are secured by grooves in one abutting surface and in these grooves springs on the opposite abutment surface of adjacent shell molds in the manner of a labyrinth seal against the ingress of spray into the mold cavity of the shell molds.
    The tightness of the plate chain against splashing water can be supported in special cases, that the shock of the closely adjacent leg of 3/11 3 steel support adjacent plates opposite the impact of the associated shell molds offset in the chain longitudinal direction, which brings an additional deflection for the water with it so that the formed by the shell molds of the plate chain, the molten metal receiving mold cavity can also be sealed under the harsh operating conditions during continuous casting against the ingress of spray water.
    The advantage of the guided, against spray water sealed, circumferential molds can also be used for co-rotating molds that form a circumferentially closed mold space, so that even with these molds simple spray water cooling can be performed. The mold only needs to have for this purpose only at least two peripheral molds, the plate chains are provided with complementary to form a circumferentially closed mold cavity shell molds.
    To support the cooling in the region of the legs of the steel supports, the shell molds in the region of the steel legs in the chain longitudinal direction extending, against the legs have open through recesses for cooling liquid, so that the shell molds made of copper can be applied in the region of these steel support with water spray.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a mold according to the invention fragmentary in a schematic section perpendicular to the chain longitudinal direction,
    2 shows a section along the line II-II of FIG. 1 on a smaller scale,
    3 shows a section along the line III-III of FIG. 2 on a larger scale,
    Fig. 4 is a representation corresponding to FIG. 1 of a design variant of a mold with two complementary to a circumferentially closed mold space plate chains and
    Fig. 5 is a section on the line V-V of Fig. 4 on a smaller scale. 4/11 4
    The mold according to FIGS. 1 to 3 has an encircling molding tool in the form of a plate chain 1, which is composed of individual plates 2 connected to one another in an articulated manner. The plates 2 are formed by shell molds 3 made of copper and steel supports with legs 4, 5 which extend along the joints 6 between the shell molds 3. The closely adjacent legs 4, 5 of the steel support adjacent plates 2 are hinged together, the hinge pins 7 also serve as bearing axles for rollers 8, which are supported on the chain length on guides 9, as shown in FIG. 2 can be removed. The shell molds 3 are provided with a groove 10 and a spring 11 on opposing abutment surfaces, so that there is a tongue and groove connection between the individual shell molds 3, as can also be seen from FIG. 2. Since the joints 12 between the articulated legs 4, 5 are preferably offset relative to the joints 6 between the shell molds 3 in the longitudinal direction of the chain, there is a relation to splashing particularly dense connection between the individual plates 2 of the plate chain 1, thus by an act of Shells 3 can be cooled intensively with spray water.
    The shell molds 3 are provided with raised side walls 13 for lateral delimitation of the strip-shaped strand. The shell molds 3 thus determine the outer peripheral shape of the belt-shaped strand to be cast, which is poured into the upwardly open mold space 14 of the shell molds 3 and cooled during its promotion in the running mold, in order to deduct a solidified band of the mold can.
    From Fig. 3 it can be seen that the connection of the shell molds 3 made of copper with the legs 4, 5 of the steel support can be done in a simple manner via cap screws 15 in the undercut grooves 16 on the side facing away from the mold space 14 of the shell molds. 3 provided in the chain longitudinal direction. These grooves 16 also form passage recesses 17 for cooling fluid, so that in a spray water cooling the spray can also reach in the region of the legs 4, 5 to the shell molds 3. 5/11 5
    According to the embodiment of FIGS. 4 and 5, the mold comprises two peripheral molds, each with a plate chain 1, wherein the plates 2 of the two plate chains form 1 shell molds 3, which face each other and complement each other to form a circumferentially closed mold space 14, as in the Fig. 4 is indicated. The two plate chains 1 are constructed analogously to the plate chain 1 according to FIGS. 1 to 3, wherein, however, results in a co-moving mold for vertical casting, as Fig. 4 illustrates. Also in this case, the advantages of the revolving plate chains 1 with respect to the watertight execution of the between the shell molds 3 opposite plates 2 of the plate chains 1 resulting mold space 14 can be utilized. 6/11
