Definitions
- the invention relates to a mold for multi-strand casting of wires and strands with small cross-sections made of metal, in particular of copper and copper alloys, the mold cavities of which are arranged in a row and which consist of graphite and have walls cooled by means of a cooling circuit.
- Hitherto known molds for multiple strand casting either have a water-cooled graphite block, into which holes that are effective as mold cavities are machined according to the desired number of strands, or graphite tubes arranged in a row, which receive a cooling jacket made of copper tube with its own water cooling.
- Both known types of molds for multiple continuous casting have considerable cache parts on.
- the graphite block containing all the bores, for example must already be replaced when only one bore no longer works properly.
- the disadvantage of the second design is essentially that its space requirement - due to the complex structure of the cooling devices assigned to the individual molds - is relatively large; moreover, it is time-consuming and not very easy to install and remove the graphite tubes, each enclosed by a cooling jacket.
- the invention has for its object to develop a mold for multi-strand casting of wires and strands with small cross sections, which is simple in construction and therefore inexpensive and can be adapted to different operating conditions with little time and technical effort.
- the newly proposed mold should in particular also be constructed in such a way that the individual mold cavities can be replaced without great effort.
- the object is achieved by a mold, which essentially has the features of claim 1.
- the concept of the solution on which the invention is based essentially consists in closing the mold from mutually independent components - namely cooling elements and mold-carrying elements to assemble, which each form self-contained units and are arranged alternately touching in a row next to each other or possibly also one above the other.
- the mold support elements containing the mold cavities are freely movable with respect to the cooling elements adjacent to them and can therefore be installed and removed without difficulty regardless of these.
- the construction of the mold from side by side or one above the other, structurally independent cooling elements and mold support elements also has the advantage that the length of the mold cavities can be changed over a wide range without removing the cooling elements; it is only necessary to replace the previously used mold support elements with those of greater or shorter length.
- the cooling elements and the mold support elements are expediently cuboid (claim 2).
- Components designed in this way are easy to produce, can be combined into a package by means of simple devices and can be removed parallel or perpendicular to their longitudinal axis by linear displacement.
- the cooling elements and the mold support elements preferably consist of copper or copper alloys.
- Each cooling element preferably has a U-shaped bore which lies in a plane perpendicular to the central plane extending through the central axes of the mold cavities (claim 4).
- the inlet and the outlet opening of the U-shaped bore preferably lies in one and the same end face of each cooling element.
- each cooling element is preferably arranged with respect to the two adjacent mold support elements in such a way that they are equidistant from the central axis of the mold cavity in question (claim 5).
- heat-conducting paste is applied to at least one of the outer surfaces via which the cooling elements and the support elements are in contact with one another (claim 6).
- Silicone paste is particularly suitable as thermal paste.
- the cooling elements are transverse to the center axis of the
- Mold cavities narrower than the mold support elements (claim 7).
- the width of the cooling elements is expediently chosen so that, with sufficient strength, the cooling bores and possibly the associated he required fittings can accommodate.
- the width of the mold support elements forms an integral multiple of the width of the cooling elements / in particular, the mold support elements are twice as wide as the cooling elements.
- the above-mentioned components lie together on a table plate (claim 8).
- the adjustable stop (s) can in particular be part of a locking screw held in a bracket.
- the mold support elements are fastened in the longitudinal direction by means of a pressure unit which is held on the table top so as to be displaceable transversely to the central axis of the mold cavity in question (claim 10).
- a particularly simple pressure unit consists of a locking screw contained in a console; the console itself is equipped with several elongated holes into which fastening and guide elements in the form of fastening screws or guide pins engage. So that the amount of cooling liquid of each cooling element can be adjusted individually, it is equipped with a flow control valve (claim 11).
- the mold can be advantageously designed in such a way that the cooling elements can be supported on the wall of a metal container serving as the metal feeder by means of the graphite inserts which protrude beyond the rear side (claim 12).
- the rear end face of the graphite inserts thus serves at the same time to fix the cooling elements and to seal them with the upstream metal container.
- Figure 2 shows a longitudinal section along the line
- Figure 3 shows a section along line III - III in Figure 2 (without upstream metal container) and
- Figure 4 shows a section along line IV - IV in Figure 1 by a cooling element.
- the mold forming the subject of the application has as essential components quaderför shaped cooling elements 1 and cuboid mold support elements 2, which are alternately lined up on the guide surface 3 'of a table top 3.
- the order of the components 1 and 2 - which are supported against one another via their outer surfaces 1 'and 2' - is chosen so that two cooling elements 1 are adjacent to each mold support element 2 (FIG. 1).
- the table top 3 has at least one console 4 with at least one locking screw 5.
- the position of this locking screw - which is equipped with a pivotable stop 6 on the side facing the cooling element 1 - is secured by a lock nut 7.
- the foririte support elements 2 each contain a tubular graphite insert 9 in the center, which encloses a mold cavity 10; in the exemplary embodiment shown, this has a circular cross section.
- the central axis of the mold support element 2 - and thus the central axis of the mold cavity 10 - is designated 10 '(see FIG. 2).
- the graphite insert 9 is provided in the region of its rear end section with a shoulder 9 ', by means of which it is supported on the mold support element 2 in the direction of the central axis 10'.
- a pressure unit 12 is arranged in front of each mold support element, as seen in the casting direction (arrow 11 in FIG. 2). This consists of a bracket 13, in each of which at least one locking screw 14 with the associated lock nut 15 is movably held.
- the console 13 is expediently attached to a foot 16, which in turn is releasably connected to the table top 3.
- the foot 16 expediently has elongated holes (not shown) into which suitable fastening screws engage; these are indicated schematically in FIG. 2 by a dash-dotted line 17.
- the associated mold-supporting element 2 can be supported against the wall of an upstream metal container 18 in the opposite direction to the pouring direction and thus be in position be secured.
- the mold support element 2 is supported via the rear end face 9 ′′ of the graphite insert 9.
- the end face mentioned lies against the wall 18 ′ of the metal container 18 in the region of the conical outlet opening 20 with the interposition of a sealing ring 19 (see FIG. 2).
- the mold support element 2 consists of copper.
- the cooling elements 1 each have their own U-shaped cooling bore 21 which can be connected to a cooling circuit via corner connections 22, 23 and a supply line 24 and drain line 25.
- the direction of movement of the cooling liquid through the U-shaped cooling bore 21 is identified by two arrows 26 and 26 '.
- the cooling bore - consisting of two longitudinal bores 21 'and a transverse bore 21 "- lies in a plane 27 (cf. FIG. 1) perpendicular to the central plane 28 running through the central axes 10' of the mold cavities 10.
- the longitudinal bores 21 ' run parallel to the longitudinal axis 1 "or to the central axis 10", the transverse bore 21 "sealed by means of a screw plug 29 perpendicular to it.
- the cooling elements 1 are made of copper.
- the longitudinal bores 21 ′ of the cooling element 1 are arranged symmetrically with respect to the associated longitudinal axis 1 "and with respect to the central axes 10 'of the adjacent mold support elements 10; they are therefore at the same distance with respect to the axes 1" and 10'.
- silicone paste can additionally be provided between the mutually facing outer surfaces 1 'and 2' (see FIG. 1); this compensates for unevenness or operational deformations and the resulting gaps between the outer surfaces 1 'and 2'.
- a sufficient cooling effect of the cooling elements 2 is ensured by the use of silicone paste even if the outer surfaces 1 'and 2' are produced less precisely and with a lower surface quality.
- the cooling elements 1 are each formed so narrow that, with sufficient strength, they can accommodate the cooling bore 21 and possibly the associated corner connections 22 and 23; the latter are each arranged on the front face of the cooling elements 1 lying in the casting direction.
- the cooling elements 1 have a width transversely to the central axis 10 ′ of the mold cavities 10, which is exactly half the width of the support elements 2. With a diameter of the mold cavity 10 of 18 mm and a diameter of the graphite insert of 30 mm, the width of the mold support elements is 50 mm; the latter are 110 mm high and 210 mm long. The graphite inserts 9 protrude 10 mm beyond the mold support elements 2.
- the length of the cooling elements 1 is preferably less than that of the mold support elements 2; it is, for example, 200 mm in the illustrated embodiment.
- the advantages of the mold forming the subject of the application consist, in particular, in that it is composed of only two simple, mutually identical components in the manner of a modular system, in particular the wear parts - i. H. after releasing the respective clamping unit 12, the mold support elements can be removed from the assembly of the other components and exchanged.
- the number of wires or strands to be cast at the same time can be influenced as desired by changing the number of components lined up next to one another or one above the other. The same applies to the length of the mold.
- mold support elements with different lengths can be used without the existing cooling elements having to be replaced.
- the mold support elements are individually by means of the associated clamping unit on the pre switched metal container, ie can be placed on a casting pot or a holding oven. If the cooling elements are each equipped with a flow control valve, the amount of cooling liquid flowing through them can be individually adjusted or controlled.
