Definitions
- the present invention relates to a mold wall Continuous casting mold consisting of an inner mold plate and a connected to the inner mold plate via screw connections There is a water tank, the inner mold plate on their side facing the water tank, there are webs in between has extending grooves with a groove width in which Filling pieces are arranged.
- Such a mold wall is generally known.
- the grooves serve as cooling channels for a coolant in the Rule water.
- the fillers serve to reduce the channel cross-section, so that the flow rate of the Coolant in the cooling channel increased. But you don't have any Supporting function.
- the attachment of the inner mold wall with the Water box is made using a variety of screws, which at least partially penetrate the water tank and the in Threaded pieces are screwed into the inner wall of the mold are arranged.
- the prior art mold wall has several disadvantages on.
- the introduction of the threaded pieces very expensive in the mold inner plate.
- the inner mold plate is usually made of copper, whereas the threaded pieces are made of steel. When replacing a worn one The inner mold plate thus falls a large amount contaminated copper, which is difficult to recycle can be supplied.
- the object of the present invention is a To create the mold wall of a continuous casting mold, which the Avoids disadvantages of the prior art.
- the wearing part of the mold inner plate only has to have the webs for forming the cooling channels. Further processing of the inner mold plate, in particular the introduction of screw connections into the inner mold plate, is not necessary. When dismantling the wearing part When the connecting elements are loosened, the inner mold plate automatically separates the inner copper plate from the steel parts. The inner mold plate is therefore easier to recycle.
- the connecting elements are special easy to insert into the undercuts.
- the connecting elements are free of play insertable into the undercuts.
- the connecting elements extendable from the filler pieces the filler pieces are particularly easy with the grooves connectable.
- the pivot elements in the swivel plane for example, a rectangular one have an elliptical or oval cross section.
- connecting elements have spreading plates, which can be extended into the undercuts by means of screws are.
- the spreading plates can be spread, for example, by means of conical spreading disks are made between the Screws and the expansion plates are arranged.
- the screws can at least in one section be conically tapered.
- Figure 1 there is a mold wall of a continuous casting mold from an inner mold plate 1 and a water tank 2.
- the inner mold plate 1 has an inner side 3 and one Outside 4 on.
- the outside 4 is in operation of the continuous casting mold the liquid metal to be cast, in particular Steel, facing.
- the inside 3, however, is the water tank 2 facing.
- the inner mold plate 1 is with the water tank 2 connected via screw connections. The screw connections are in Figure 1 by the dashed lines indicated.
- the inner mold plate 1 faces vertically extending webs 5. Run between the webs 5 consequently grooves 6 with a groove width a. How special can be clearly seen from Figure 2, the grooves 6 have undercuts 6 'with an undercut thickness b.
- the grooves 6 In the grooves 6, filler pieces 7 are arranged. On the fillers 7 threaded bolts 8 are welded, by means of which the filler pieces 7 and thus also the inner mold plate 1 with the Water box 2 are screwed. The screw connections between the inner mold plate 1 and the water tank 2 are thus arranged between the filler pieces 7 and the water tank 2.
- the connection between the filler pieces 7 and the inner mold plate can be seen from Figures 3 and 4.
- the connecting elements 9 have a connecting element thickness c on.
- the connecting elements 9 engage Swivel elements 10 releasably into the undercuts 6 '.
- the pivot elements 10 are pivotable about pivot axes 11. In swivel planes standing perpendicular to the swivel axes 11 12, the pivot elements 10 have a maximum length d and a maximum width e.
- the maximum length d is greater than the groove width a.
- the maximum width e is according to the embodiment smaller than the groove width a. But it could also be as large as the groove width a.
- the connecting elements 9 By pivoting the pivot elements 10 in their pivot plane 12 are the connecting elements 9 from the filler pieces 7 extendable.
- the connecting elements 9 thereby releasably engage in the undercuts 6 '.
- the fillers 7 are can thus be positively connected to the inner mold plate 1.
- the pivot elements 10 have in the pivot plane 12 has a rectangular cross section.
- the cross section but can also be designed differently, e.g. B. elliptical or oval.
- the connecting element thickness c is less than the undercut thickness b.
- the swivel elements 10 particularly easy to insert into the undercuts 6 '.
- the connecting elements 9 and / or the undercuts 6 ' are also conical his.
- the connecting elements 9 can be pivoted according to FIG Figure 5 also have tapered expansion plates 13.
- the spreading plates 13 are by means of screws 14 in the undercuts 6 'extendable. Extending the spreading plates 13, as shown in FIG. 5, can be done by that between the screws 14 tapered spreading washers 15 are arranged. Alternatively or in addition the screws 14 also - at least in one section - be conically tapered.
- the connecting elements 9 are the connecting elements 9 according to Figures 5 and 6 spring elements 16 assigned.
- the Spring elements 16 as O-rings made of a permanently elastic material trained, which occurs during continuous casting Resists temperatures and has a sufficient thickness.
