BRIEF SUMMARY
FIELD OF THE INVENTION
This is a national phase application corresponding to PCT/DE81/0074 filed May 21, 1981.
The invention relates to a chill mold for multiple continuous casting of wires and strands of small cross-section from metal, in particular copper and copper alloys, where the mold cavities are disposed in a row and have walls of graphite cooled by a coolant cycle.
BACKGROUND OF THE INVENTION
Based on the small casting output of wire chill molds and chill molds for casting strands of small cross-section such horizontal strand casting plants operate according to the multiple continuous casting principle, that is at the same time, for example, four to ten wires or casting strands are produced.
The chill molds known to date for multiple continuous casting comprise either a water-cooled block of graphite having bores acting as mold cavities or graphite tubes disposed in a row, having a cooling jacket from copper tubing with their own water cooling. Considerable disadvantages are associated with each of these two known constructions of chill molds for multiple continuous casting. In the construction first mentioned for example the graphite block containing all bores must be replaced even when only one of the bores does not work properly. The disadvantage of the second construction comprises essentially that its spatial requirements are comparatively large because of the cooling devices coordinated to the individual chill molds. In addition, it is time consuming and not simple to mount and to dismount the graphite tubes when they are, in each case surrounded by a cooling jacket.
OBJECTS OF THE INVENTION
It is an object of the invention to provide a chill mold for multiple continuous of wires and casting strands of small cross-section, which is simple, of low cost and adaptable to different operating conditions. Another object is to provide a chill mold such that the individual mold cavities can be replaces without complicated requirements.
SUMMARY OF THE INVENTION
The object is achieved with a chill mold cavities which alternate with cooling elements each of which has its own cooling bore connectable to the coolant cycle. The cavities each have a graphite insert in a mold support elements forming a row such that for each support element at least two cooling elements are disposed on the sides. Each mold support element individually can be pressed opposite to the casting direction against a stop surface (18') and the cooling elements and the mold support elements can be fastened to each other transverse to the casting direction. The idea on which the invention is based is to compose the chill mold from independent building blocks, that is cooling elements and mold support elements, which in each case form units complete within themselves and which are stacked alternatingly in contact in a row next to each other or possibly on top of each other. The mold support elements containing the mold hollow spaces are freely movable relative to the cooling elements adjacent to them and they can be mounted and dismounted independently from the cooling elements without difficulty. This has the advantage that the mold hollow spaces can be changed in length over a wide range without dismounting of the cooling elements, it is only required that the presently employed mold support elements be replaced by others having a greater or lesser length.
Advantageously the cooling elements and the mold support elements are constructed as parallelepipeds. Building blocks of such shape can be easily produced, they can be combined with simple provisions to a packet or stack and they can be dismounted by straight line shifting parallel to or perpendicular to their longitudinal axis.
In order to increase the cooling effect of the cooling elements on the mold support elements the two cited building blocks are formed from a metal having good thermal conductivity with the exception of the graphite insert. Preferably the cooling elements and the form support elements are constructed from copper or copper alloys.
