Definitions
- the invention relates to a method for producing molds for ingot casting plants, copper or a copper alloy as the starting material is taken.
- the invention also relates to a device for carrying it out of the procedure.
- Such pigs have a weight of typically 6 kg.
- four ingots are poured into a mold, whereby the liquid pig iron solidifies in the mold and both Both the ingot and the mold can be cooled by water spray.
- the ingot molds or molds of known ingot casting machines are usually made of Cast iron made. They are subject to comparatively high wear and must therefore be replaced again and again according to the wear.
- DE 42 33 522 A1 describes a method for producing a wide mold side wall for a thin slab caster, which with the entrance mentioned genre does not match.
- a method for producing a broad side wall is claimed there a thin slab caster, which starts from the top edge the sides and downward expansion area.
- DE 42 33 739 A1 discloses a non-generic device for precise, rational production of a broad side wall for the continuous mold a thin slab caster with one starting from the upper edge the sides and downward extension area.
- a die plate which has a molding surface for Includes a mold broad side wall, the working side of one assigned a plurality of individually adjustable sub-areas formed pressure area is.
- From document DE-C-927 503 is an adjustable deep-drawing device for Manufacture of membranes or other profiled sheets known from a press tool with a press ram and a die for cold forming the sheets exist.
- the die has concave depressions on and the form or press die cooperating with the die shows oppositely shaped and raised form elements.
- a manufacturing process This document does not allow mold shapes, especially those made of copper remove.
- a press device for Manufacture of profiled sheets known for the automotive industry consists of a press ram and a die. Press stamp and Die have oppositely designed and raised form elements to make the To give sheet metal the desired shape. What is claimed in this document Process refers to the production of especially flanged Sheets. A method of making molds, in particular made of copper, does not state this document.
- the object of the invention based, a method and an apparatus for producing molds for ingot casting systems to be specified using circuit boards the difficulties of copper or copper alloys as a starting material and technical limits when cold-forming them into ingot molds overcome by train forming / train pressure forming and which a crack-free and economical production of the ingot molds.
- a strain-hardened circuit board made of a copper alloy is soft-annealed before being used for the first forming step.
- the copper board achieves one Elongation at break of at least 35% and you are in the Able to realize comparatively large changes in shape without crack formation.
- a further development of the method provides that in as a starting material copper board used one or more integrally connected, preferably four, molds can be molded.
- an embodiment of the method according to the invention provides that the raised form elements of the die and the concave formed with these co-operating recesses of the die congruent shape contours form. This results in an approximately constant thickness of the deforming material area reached.
- Essential to the invention is the measure that both in the form stamp as well as with the die, all shape contours with radii are constantly interlocking pass. Edges and sharp corners must be avoided completely in order to give the material an opportunity to relieve tension caused by cold Mine material. Sharp edges would prevent this and therefore Initiate crack formation.
- the copper board by means of a detonation force, for example triggered by explosives, on a concave shaped die is deformed, the thickness of the copper plate corresponds to the wall thickness of the mold.
- a preferred alternative development of the invention is that the Copper plate by means of hydroforming, triggered by high water pressure a concave shaped die is deformed, the thickness of the copper board corresponds to the wall thickness of the mold.
- a device for the production of molds for ingot casting plants Production of ingots is characterized in that at least between one with a concave mold shape and a counter the die clamped reaction stamp a hydraulic pressure chamber with high pressure water connection is arranged and the circuit board made of copper or made of a copper alloy seal-proof at the edge, i.e. about a flameproof Seal between reaction stamp and die is clamped.
- the circuit board 2 made of copper or a copper alloy shown in plan view in FIG. 1a has four adjacent, similar mold shapes 1 in the manner of trough-shaped depressions. Like the side view 1b shows, the depressions of the mold shapes have, for example, one upper width B and a depth T a width / depth ratio> 1.
- the pressing tool 9 shown in FIG. 2 has a solid die 4 with likewise concave, egg-cup-shaped cross-section, the molds 1 forming depressions 6, whereas the one with the die 4 interactable mold or press rams 3 counter-shaped, raised Has shaped elements 5. Between them is the board to be deformed 2 with a thickness between 50 and 85 mm pressed into the mold.
- Board material is copper or a copper alloy, e.g. CuAg, CuCrZr or CuNiBe provided.
- the pressing tool 9 molding means namely Form stamp 3, shaped element 5, recess 6 and contour 7 for the at a pressing process simultaneous configuration of at least one, preferably of has four mold troughs.
- the pressing tool 9 can be seen for the forming process extremely high pressing forces required, for example in the order of a few can lie a thousand tons and with a correspondingly strong, preferred hydraulic press 13 with a uniformly slow penetration speed must be applied.
- Fig. 2 shows that the pressing tool 9 guide elements 10, 11th has, which assigned the pressure stamp 3 and the die 4 together are.
- the edge areas 8 of the circuit board 2 are known per se Way, for example in conventional deep-drawing processes, hold-down device 12 provided, which prevent inadmissible deformation of these edge regions 8 and hold the board in position and in tension during the deformation.
- the board can be made of pure copper, copper alloys or solidified Copper alloys are used.
- FIG 3 shows an alternative device for producing molds for Ingot casting machines for the production of ingots with a hydroforming Copper board is made.
- This device has at least one with a concave mold 1 formed die 4 and a against the die 4 clamped reaction stamp 14 a hydraulic pressure chamber 15 on.
- This hydraulic pressure chamber 15 is with a connection for high water pressure connected.
- the board 2 to be deformed made of copper or a copper alloy is on the edge and on all sides between the reaction stamp 14 and the Die 4 clamped, as is also indicated in Fig. 2.
- the sublime The edge of the reaction stamp 13 lies on the edge areas 8 of the copper plate seal-tight, so that the water pressure in the hydraulic pressure chamber without Pressure drop can act on the copper plate and this in the mold 1 can be molded into the die 4.
- This device is also possible All shape contours 7 are provided with radii that continuously merge into one another.
