    专利说明:

    The invention relates to a sliding closure for a container containing molten metal, with a fastened to this housing part and a longitudinally displaceable relative to him slide unit, in each of which a refractory slide plate is used, wherein the slide unit of a plurality of perpendicular to her on the housing part fasteners longitudinally displaceable is held.
    Sliding closures of this type are known to be used in continuous casting for opening and closing the spout opening of a metallurgical vessel. In operation, high temperatures are caused by the molten steel, which are also transferred to the slide housing in the vicinity of the refractory slide plates. In the outer area of the housing, on the other hand, much lower temperatures prevail, for example near room temperature in the environment. The slider housing must still be stable in this area for the attachment of the holding means for the slide unit.
    A sliding closure of the type mentioned is disclosed in EP-A-1 119 428, in which the housing part extends in the direction of displacement over the entire length and laterally to outside the holding means, so that these holding means in the region between the slide plates and the longitudinal walls of the housing part are placed. Although this makes it possible to achieve a high rigidity of the valve housing, there is at the same time an increased susceptibility to cracking, since the large temperature gradient between the inner and the outer region of the housing causes different thermal expansions and thus very high stresses in the transition zone between the two areas.
    In addition, the holding means fixed in the housing part are connected to each other on both sides of the closure plates by a connecting rod. This has the effect that the slide unit can only be released from the housing part if it can be displaced into this position lying outside the open and closed positions, in which case the spring elements are relaxed.
    The invention has for its object to avoid these disadvantages and to provide a sliding closure of the type mentioned, which can be opened in a fault, especially when the slide unit is no longer movable. In this case, the housing part should not be susceptible to cracking and, as it were strength-wise stable enough, so that the holding means which hold the slide unit to him, are properly stored.
    This object is achieved by the features of claim 1 and 6 according to the invention.
    Due to the releasable individual attachment of the retaining means on the housing part, such that they can be solved in the clamped state of the sliding closure approximately in any position of the slide unit of the housing part, a significant advantage in the operation of a sliding closure, because thus at the off and To occur disturbances opening the same is often possible without the holding means and / or other parts must be destroyed.
    Very advantageously, the housing part of the sliding closure in the longitudinal direction relatively close to the slide plates extending walls with lateral projections, which are provided with bearings for the individual holding means of the slide unit.
    In this way, the otherwise resulting in the housing part voltages can be largely eliminated, because in operation, the eye-shaped bearings can independently adjust the heating, even if there are significant temperature differences.
    The required stiffness of the housing is still sufficient for the safe storage of the holding means for the slide unit in the eye-shaped bearings of the housing rests and it is thus achieved an improved straight-lasting disc support.
    The invention also provides that the housing part has on both sides two lateral projections, whose bearings are arranged in the housing part symmetrically to the spout opening of the slide closure. This symmetrical arrangement allows optimum transmission of force of the holding means on the slide unit and thus on the against each other to be pressed slide plates of the closure.
    The invention further provides that the holding means are provided with guide rails of the slider unit parallel to the working plane of the sliding shutter sliding rollers, which are acted upon by the guideways arranged in the bearings spring members. In this way, any deformations of the eye-shaped bearings are compensated, without affecting the leadership of the slide unit along its guideways.
    It is expedient in terms of a simple construction of the holding means, if they have a guided in their camps bolt-shaped connecting member and a preferably releasably connected thereto carrier for at least one sliding role.
    It is also constructive and assembly technically useful if the eye-shaped bearings are designed as bearing bushes and these receiving approaches are provided with a bush diameter adapted semi-circular end portion, preferably in the form of a front end semi-shell.
    The invention also provides that the slide unit is hinged to the housing part by means of a hinge connection, the hinge wings are attached on the one hand to the slide unit and on the other hand directly to the one longitudinal wall of the housing part. As a result, the hinge wings are securely fastened to the housing part.
    The invention and further advantages are explained below with reference to an embodiment with reference to the drawings. It shows:<Tb> FIG. 1 <SEP> a sliding closure according to the invention, in the unfolded position and in perspective; and<Tb> FIG. 2 <SEP> shown the slide closure of Figure 1 in section and in the closed position.<Tb> FIG. 3 is a perspective view of the sliding closure according to FIG. 1 in the case of the slide unit released according to the invention from the housing part;<Tb> FIG. FIG. 4 shows a plan view of a projection on the housing part of the sliding closure according to FIG. 1 with the retaining means fixed, and FIG<Tb> FIG. 5 <SEP> a plan view of the approach with dissolved holding means.
    The sliding closure 10 according to Fig. 1 and Fig. 2 is suitable as a closure member in a casting ladle not shown in detail or a similar metal melt containing container, as these are used in particular in continuous casting of steel. Of course, it is also suitable as a closure member, for example, foundries in non-ferrous metal area.
    This sliding closure 10 consists essentially of a housing part 1 and a longitudinally displaceable to this slide unit 2, which is articulated longitudinally on the housing part 1 with a hinge connection 3. In the housing part 1, an upper refractory bottom plate 4 is fixed to the folded state, a lower refractory slide plate 5 of the slider unit 2 is pressed, the latter of several perpendicular to her on the housing part 1 fixed holding means 6a, 6b and 7a, 7b is held longitudinally displaceable.
    The normally cast housing part 1 has in the longitudinal direction relatively close to the plates 4, 5 extending outer walls 8, 9 with lateral projections 10a, 10b and 11a, 11b, preferably with eye-shaped bearings 12 for the individual holding means 6a, 6b and 7a, 7b of the slider unit 2 are provided.
    These lateral walls 8, 9 of the housing part 1 are each dimensioned at a distance of approximately one to several centimeters to the outer sides of the plates 4, 5, so that this housing part has an approximately uniform temperature distribution in the operating state when casting.
    The holding means 6a, 6b and 7a, 7b are in turn provided parallel to the working plane of the slide fastener 10 with guide rails 13a, 13b of the slide unit 2 sliding rollers 14 which act against the guide tracks 13a, 13b installed in the bearings 12 spring members 15 are. These guideways 13a, 13b are in turn divided in a conventional manner by an opening 34 for the release of a respective sliding roller 14 and provided at the ends with ramps 33 to brace the holding means and with them the spring members or relax, as described in the document EP-A-1 119 428 is explained in detail.
    The bearings 12 of the holding means 6a, 6b, 7a, 7b are formed as bearing bushes, wherein they receiving lugs 10a, 10b; 11a, 11b are provided with a sleeve diameter adapted semi-circular end portion in the form of a front end of the final half-shell.
    As can be seen from Fig. 1, the housing part 1 on both sides of two lateral projections 10a, 10b and 11a, 11b, the bearings 12 are placed in the housing part 1 symmetrically to the spout opening 16 of the slide fastener 10. This arrangement enables optimum power transmission from the holding means 6a, 6b; 7a, 7b on the slide unit 2 and thus on the pressed against each other in the closed state plates 4, 5th
    The individual holding means 6a, 6b; 7a, 7b consist of a guided in the bearings 12 bolt-shaped connecting member 17 and a releasably connected thereto for ease of assembly support 18 for the mounted thereon roller. Alternatively, the carrier 18 may be provided on both sides with sliding along their own guideways casters. Instead of sliding rollers and sliding blocks and similar sliding elements are used.
    According to the invention, these holding means 6a, 6b; 7a, 7b so individually on the housing part 1 releasably secured, that they can be solved in the clamped state of the sliding closure 10 approximately in each position of the slide unit 2 of the housing part. This is particularly important in a fault, if the slide unit can not be moved primarily in a breakthrough because of welded molten steel.
    Fig. 3 shows the invention solved by the housing part 1 slider unit 2. There are with the slide unit, the bearings 12 of the holding means 6a, 6b; 7a, 7b each bayonet-like by twisting away from the housing part 1 perpendicular to this. The bearings 12 and with them the holding means 6a, 6b; 7a, 7b are each rotated by a certain angle, thereby also the associated with these rollers 14 are pivoted, which bear against the guideways 13a, 13b of the slide unit 2. The holding means 6a, 6b; 7a, 7b with the bearings 12 can then be taken away from the slide unit 2 and, depending on which, are fastened again in the housing part 1.
    Conveniently, the bearings 12 of the holding means 6a, 6b; 7a, 7b are each formed with longitudinal guides 12 which run uniformly parallel to the circumference on their outer side and which in each case like a bayonet in corresponding grooves 10, 11 of an opening 10, 11 in the projection 10a, 10b or 11a. 11b of the housing part 1 inserted and then secured by a twisting and fixing means of a locking means 26 therein. These openings 10, 11 are provided with a cylindrical part in which a respective bearing 12 can be rotated and positioned.
    Fig. 4 shows the one approach 10a of the housing part 1 and fixed therein by the locking means 26 bearing 12 of a holding means. The bearing 12 is in the respective opening 10, 11 so twisted until its longitudinal guides 12 over those of the openings 10, 11 rest.
    In contrast, in Fig. 5, the position of the bearing 12 with remote locking means 26 and rotated position in the opening 10, 11 illustrates, in which the bearing 12 is moved with its longitudinal guides 12 through the grooves 10 and from Housing part 1 can be removed. The inner wall of the opening 10, 11 are each associated with corresponding longitudinal guides 27 to those of the bearing 12, between which the grooves 10 extend.
    To attach the sliding closure to the ladle serve not shown fixing screws, which are in corner flaps 19 of the housing part 1 swiveled and then tightened against it.
    The actuation of the slide unit 2 is effected in turn by a likewise not illustrated drive member in the form of a hydraulic cylinder, the push rod with a coupling claw 20 of the slide unit is connectable.
    In order to enable the opening and closing of the sliding closure, the slide unit 2 is hinged in a conventional manner to the housing part 1 by means of the hinge connection 3, wherein the hinge wings 21, 22 on the one hand to the slide unit 2 and on the other hand directly to the one longitudinal wall 9 of the housing part 1 are attached.
    The inventive construction of the housing part 1 is also suitable for a sliding closure, the retaining means 7a, 7b; 8a, 8b are formed differently than described above, as far as they have a storage of the holding means in the lugs 10a, 10b; 11a 11b of the slide unit 2 is possible.
    The invention is sufficiently demonstrated with the illustrated embodiment. But it could still be illustrated by other variants. So it could also be a three-plate sliding closure, in which between the housing part and the slider unit, a slide plate would be slidably disposed in an additional frame in a conventional manner. The housing part would then be formed in the same way as in the variant of FIG. 1 with the inventive advantages, in which case the slider unit would be guided only for automatic clamping of the shutter slidably.
    The holding means could be releasably attached differently than bayonet-like on the housing part, such as by a kind of screw connection or a snap-in coupling or the like.
