Definitions
- the invention relates to a method and a device for carrying out the method for producing rolling stock from oxygen-free copper, in particular wire in a casting and rolling plant, consisting of a melting plant, a casting plant and a downstream continuous rolling mill.
- a method and a device corresponding to this type can be found in US-A-4290823.
- the aim of the present invention is to provide a method and a device for carrying out the method, with which it is possible to produce oxygen-free copper wire in-line in a casting and rolling plant of the generic type.
- the basis of the invention is the knowledge that the phenomenon of hydrogen disease known in the art is not relevant to oxygen-free copper.
- the present invention proposes that, starting from the method according to the preamble of claim 1, the ingot leaving the casting plant in a straight line the horizontal is bent after it has been reduced in at least one deformation stitch, the deformation stitch of the ingot and the melting and casting process taking place in a protective gas atmosphere.
- the invention therefore consists in reducing the grain sizes of the copper by deforming the copper ingot immediately behind the mold and thereby preventing larger hydrogen bubbles from forming at the grain boundaries.
- the fine structure largely prevents the deep penetration of the hydrogen and thus represents an effective remedy against the crack and fracture sensitivity of the copper bar.
- the first deformation stitch is preferably carried out close behind the casting installation.
- the bending of the copper ingot after the first or, if necessary, several reduction stitches in a protective gas atmosphere is harmless due to the reduced grain size and no longer leads to the cracks that could not previously be prevented.
- a casting and rolling plant for carrying out the method according to the invention is characterized by the combination of features according to claim 4.
- the deformation unit arranged close to the casting machine is thus arranged at the same inclination as the casting system, it being possible, if appropriate, to provide further devices for preparing the ingot (edge milling device, driver, etc.) between the casting system and the first deformation framework.
- the single drawing figure shows a schematic representation of a casting and rolling plant according to the invention. It consists of the melting furnace 1, the holding furnace 2, the pouring channel 3, the tundish 4, the pouring spout 5 of which protrudes into the area of the strip casting mold 6, the driver 7, the edge processing device 8 and the deformation frame 9.
- the melt in the melting furnace 1 and also in the holding furnace 2 is covered with charcoal to avoid oxygen absorption.
- the invention also provides for the melting furnace 1, the holding furnace 2, the casting trough 3 and the casting trough 4 to be housed and these units to be operated in a protective gas atmosphere.
- the housing is marked with H. All facilities are as tight as possible and - contrary to the usual gas heating - are inductively heated.
- the Nitrogen is preferably blown in the direction of the material flow and flows towards the tundish, where it emerges together with the molten copper.
- the nitrogen flowing out of the tundish 4 protects the inlet area of the belt casting mold 6 against oxygen absorption due to its specific weight against air.
- mudguard structures on the side can cause the nitrogen to have a longer dwell time in this area and thus offer protection from oxygen.
- the housings continue behind the belt casting mold 6; they include driver 7, edge processing device 8 and deformation stand 9 and possibly also the bending area 10. Following the deformation stand 9, the ingot in the turning area 10 is diverted from the casting direction into the horizontal, as is in accordance with the teaching of the invention.
- the system works as follows: The copper melt located in the melting furnace 1 is temporarily stored in the holding furnace 2 and passed through the trough 3 into the tundish 4. All units are sealed in a housing H, a protective gas atmosphere is created inside the housing H. From the tundish 4, through which nitrogen flows, the copper melt reaches the strip casting mold, in which a copper ingot is poured between the strip-shaped mold sides, which leaves the strip casting mold 6 in the casting direction after solidification.
- the copper bar which has a temperature of 980 to 1000 ° C., is driven into the Edge processing device 8, a milling machine, introduced where the edges of the billet are chamfered.
- the copper bar prepared in this way is then introduced into the forming frame.
- the construction of the deformation stand must have features which are unusual in the case of roughing stands in copper wire systems.
- the tip of the copper bar, on which the starting piece is still located, must be able to pass through the deformation frame 9 without deformation. Therefore, the rollers of the deformation stand 9 are first opened. When the desired strand speed is reached, the rolls are automatically closed until the preselected reduction is reached. For this purpose it is necessary that the speed of the rollers is determined and regulated depending on the respective deformation. This can be achieved by measuring the speed and current consumption of the driver 7.
- a reduction in the stitch of approx. 35% takes place in the deformation stand 9.
- the reduced copper ingot in the bending area 10 of the system is moved horizontally on a roller table and reduced to wire in further rolling stands of the continuous rolling mill 11. This copper wire produced in this way is bundled at the end (not shown) of the casting and rolling system.
