- a molten metal having conductivity that is, a molten metal of non-ferrous metal (for example, Al, Cu, Zn or Si, or at least two alloys of them, Mg alloy, etc.) or non-ferrous metal
- Nonferrous metal products or other metal products are produced by casting from molten metals other than the above.
- As an initial step of the steps there are the steps of dissolution and component adjustment.
- scrap recycling has also become popular.
- metals obtained from scrap contain impurities. That is, first, the scrap as a raw material originally contains impurities.
- impurities are generated at the time of scrap melting work and melt into the molten metal. For this reason, it is not avoidable that impurities are contained in the molten metal from which the scrap is reused. If non-ferrous metal products or other metal products are produced from such molten metal, the products contain impurities, which lowers the quality and performance of the products. From this point of view, it is extremely important to remove impurities from the molten metal from scraps. Therefore, conventionally, impurities have been removed from the molten metal by various methods. For example, it has been practiced to filter out and remove impurities in the molten metal using a filter.
- the impurities can be removed to some extent from the molten metal also by the method using the above-mentioned flux or gas. However, even this method can not sufficiently remove impurities. Furthermore, even if the molten metal from which impurities have been removed using flux or gas is further filtered by a filter, the impurities in the molten metal can not be sufficiently removed.
- the present invention has been uniquely made only by the present inventor based on the above-mentioned present inventor's unique awareness of the problem, and the purpose is to make the impurity more accurately from the melt of non-ferrous metals including impurities and other metals. Attempt to provide an apparatus and method for making it possible to obtain a high purity molten metal and to obtain high purity non-metallic products and other metal products from the high purity molten metal by making is there.
- the present inventors previously disclosed another invention different from the present invention in Patents 5669504 and 5431438.
- the technical ideas described in these publications are intended to improve product quality by reliably rotating the melt as fast as possible with a large stirring force, and are not intended to remove impurities from the melt. Therefore, the present invention is another invention which is completely unrelated to the invention of the above-mentioned publication and which is completely unrelated to the technical idea, and is not an invention which can be made from the invention of the above-mentioned publication.

- the present invention was made for the purpose of solving the above-mentioned technical problem unique to the inventor, that is, the problem of obtaining high-quality products from molten metal containing impurities. . That is, the present invention is based on the results of a plurality of experiments conducted independently by the present inventor in an attempt to solve this technical task, and the present inventors have been compared to the present inventor for solving such a technical task. It is an invention that is virtually impossible for other engineers who are not forward-looking and who have not conducted multiple experiments independently.
- the inventor of the present invention continuously conducts technical research to obtain a melt of higher purity nonferrous metal and other ferrous metal suitable for producing higher quality nonmetal products and other metal products. I was going. In the process, other engineers, who remove the impurities themselves from the recycled molten metal containing a large amount of impurities, are uniquely motivated to solve technical problems that are not very positive.
- the present inventor noticed that the nonferrous metal containing an impurity and the molten metal of other iron metals could be grasped as what is called a multiphase fluid. That is, it has come to be thought that it can be grasped as a multiphase fluid of a nonferrous metal as a base and a molten metal of other ferrous metals and a molten metal of an impurity dissolved therein.
- the multi-phase fluid is a multi-phase fluid in terms of Archimedes' Electromagnetic Force
- the fluid as the base and the fluid (particles) of the impurities dissolved in it It should be comprehensible.
- the melt of nonferrous metals and other ferrous metals containing impurities is a multiphase fluid in Archimedes 'electromagnetic force
- pressure gradient to the melt of nonferrous metals and other ferrous metals as base by Archimedes' electromagnetic force Should be able to move the impurities in the melt of nonferrous metals and other ferrous metals according to the pressure gradient, thereby separating the base and the impurities.
- FIGS. 24 to 26 are diagrams showing the distribution of the impurity (Al 3 Fe) obtained from the color photograph of the end face of the product. As can be seen from these figures, it was possible to collect impurities (Al 3 Fe) in the peripheral part of high-purity aluminum in the central part.
- the removal processing of the impurities to be performed later can be performed while visually confirming the removal operation of the impurities while looking at the end face, or This can be done after visually checking in advance and obtaining the location of the impurities, so that the impurities can be easily and surely removed from the product.
- the present invention was made based on the discovery obtained by the experiment conducted by the inventor independently, and is an invention that only the inventor who conducted the experiment could do, the experiment described above. Another person skilled in the art who did not do this is an invention that could never be done. In particular, it is considered that only the present inventors could do to make the impurities gather around the product rather than above and below it.

- the pressure resistance is provided between the container body 5 and the end plates 6 and 7 in order to maintain the internal high pressure state even when the internal pressure of the container 1 becomes high.
- the electrodes 8 and 9 are detachably attached to the end plates 6 and 7. Thereby, the electrodes 8 and 9 can be replaced with another one at the time of wear.
- the container main body 5 can have various configurations so that the product P in which the molten metal M is solidified can be easily taken out. For example, it can be divided into two. Also, the inside can be tapered.
- FIG. 2 as a plan view of the device 100, etc., an annular magnetic field device 2 constituted by permanent magnets is arranged at the outer peripheral position of the container body 5.
- the N pole of one magnet (magnet body) 2 a and the other magnet (magnet body) 2 b are horizontally opposed.
- the south pole of one magnet 2a and the north pole of the other magnet 2b may be opposed.

- the magnetic field device 2 is also removable from the device 100.
- the metal product manufacturing apparatus 100 has a magnetic field device 2 as can be seen from FIGS. For this reason, when the current I flows through the molten metal M in the operating state of the magnetic field device 2, the first Lorentz force (electromagnetic force) and the second Lorentz force (electromagnetic force) simultaneously work. However, as described later, when there is no magnetic field device 2 or in a non-operating state, only the first Lorentz force acts.
- the first Lorentz force is an electromagnetic force due to the crossing of the current I and the magnetic field based on the current I.
- the second Lorentz force is an electromagnetic force due to the crossing of the current I and the externally applied magnetic field.
- the first Lorentz force is a force toward the center of the molten metal M, whereby a pressure gradient is created in the molten metal M, and the electromagnetic force of Archimedes acts on the impurities in the molten metal M, and the impurities move around the molten metal M Do.
- the second Lorentz force is applied to the molten metal M in the direction to drive it laterally. That is, the current I flowing in the molten metal M intersects with the magnetic field from the magnetic field device 2 to generate a second Lorentz force, which is applied to the molten metal M.
- the molten metal M of non-ferrous metal or ferrous metal is accommodated in the container 1, and in this state, current flows downward from FIG. 9 to the lower electrode 9 from the upper electrode 8 through the molten metal M.

- This current distribution is obtained from the knowledge obtained based on the experience that the inventor has dealt with the technology of the technical field of the present invention for a long time. And, the fact that this current distribution is technically correct is supported by the fact that according to the present invention, as described above, the products shown in FIGS.
- the current density is high in the vicinity of the electrodes 8 and 9, and the current density is low in the position away from the electrodes 8 and 9.
- the current I flowing between the pair of electrodes 8 and 9 is simulated as a collection of a plurality of unit currents Iu via the molten metal M. It is illustrated in a rough and dense state.

Thereby, the molten metal M vibrates in small steps. By this small vibration being applied to the molten metal M, impurities are accumulated in the peripheral portion PP of the product by Archimedes' electromagnetic force as shown in FIG. 14 in the process of changing the molten metal from liquid phase to solid phase by cooling. Finally, a product P as shown in FIG. 14 is obtained.
- an alternating current for example, 1 to 10 Hz etc.
- this product P if the impurities IM in the peripheral part PP are removed by a desired method, a metal product with high accuracy can be obtained. As described above, this impurity removal operation can be performed easily and reliably because the impurities are accumulated around the product P and it is easy to grasp visually, and non-ferrous metals and other metals with higher precision can be performed. Product P can be obtained with certainty.
- the metal product manufacturing apparatus 100 of the present invention can have various configurations and usage modes. For example, the following aspects can be taken.
- a magnetic field The device 2 can also be removed or deactivated. This is due to the following reasons.
- the magnetic field generated by the alternating current changes in the N and S directions.
- the external magnetic field is a static magnetic field.
- the static magnetic field and the external magnetic field cancel each other. Therefore, when an alternating current flows, it is preferable to remove the external magnetic field.
- the direct current was flowed in the state which applied the magnetic field by the magnetic field apparatus 2.
- the container 1 is removed from the metal product manufacturing apparatus 100, and the state shown in FIG. 1A is obtained. Then, in the removed container 1, as shown in FIG. 8, the upper end plate 6 is removed, and solid non-ferrous metal containing impurities or other metal as a raw material is accommodated in the container 1. The upper end plate 6 is then sealingly attached to the container body 5.
- the raw material for example, non-ferrous metals containing impurities or other metals selected from scrap and the like can be used.
- the quantity of the said raw material selects the quantity electrically conducted with a pair of electrodes 8 and 9, when it melts
- the container 1 is put in a heating furnace (not shown) such as an electric furnace and heated to melt the raw material in the container 1, that is, non-ferrous metals or other metals, to form a molten metal M.
- a heating furnace such as an electric furnace and heated to melt the raw material in the container 1, that is, non-ferrous metals or other metals, to form a molten metal M.
- the vessel 1 is taken out of the melting furnace and it is incorporated into the apparatus 100 as shown in FIG.
- the molten metal M in the container 1 can be supplied with the current I by the pair of electrodes 8 and 9, and the magnetic field device 2 can apply a magnetic field to the molten metal M.
- the metal product manufacturing apparatus 100 is cooled in a state where a direct current I flows.
- the solidified nonferrous metal or other metal product P is removed from the container 1.
- the end face of the billet-like product P thus obtained is shown, for example, in FIG. That is, the product P is obtained as having a large amount of impurities in the peripheral portion PP and almost no impurities in the inner portion IP. Thereafter, the peripheral portion PP of the product P is removed by a desired means to obtain a final product. In order to mass-produce the product P, a plurality of metal product manufacturing apparatuses 100 may be provided.
- the magnetic pole is switched at a predetermined cycle (1 Hz to 10 Hz etc.) using the electromagnet as the magnetic field device 2, and the magnetic field line ML runs from right to left as shown in FIG. It is also possible to switch between running from left to right. In this case, a direct current may be supplied as the current I.
- the container 1 is cylindrical and the billet is obtained as the product P is exemplified, but the container 1 is made as a rectangular cylinder and the slab is obtained as the product P You can also
- the container body 5 was made of a mullite tube. In this, as a non-ferrous metal containing impurities as a raw material, -1018 mm ⁇ length 50 mm of Al-10 mass% Fe was housed. Graphite electrodes were used for the pair of electrodes 8 and 9.
- the container 1 containing the molten metal at about 1000 ° C. is incorporated into the metal product manufacturing apparatus 100, a magnetic field (0.54 T) is applied by the magnetic field device 2, and direct current of various values as the current I between the pair of electrodes 8 and 9 Cool while flowing
- the value of the current I was appropriately selected from the range of 20A-100A.
- the voltage applied at this time may be adjusted so that the current has a desired value.
- the product P (prototype) obtained by this was verified as follows. That is, the end face of the obtained product P was rough-polished by a known means and then buffed. The observation of the macrostructure of this end face and the organization observation by an optical microscope were performed. 22 to 26 were obtained based on the color photographs of the macroscopic structure obtained at this time. These FIGS. 22 to 26 selectively show Al 3 Fe as an impurity which causes deterioration of the quality particularly in aluminum. 22 to FIG. 26 respectively indicate the value of the current flowed and the dimensions of the product.
- the impurity Al 3 Fe could be accumulated in the peripheral portion PP of the product P.
- Al 3 Fe is more concentrated in the peripheral part PP when a current of 100 A or less is applied. Considering this, when the current is large, it is inferred that the electromagnetic forces F11, F21, F12, and F22 are too large and dispersion of Al 3 Fe occurs in the base. From this, it appears that optimum values exist for the values of the strength of the magnetic field of the magnetic field device 2 and the magnitude of the current.
- the optimum value depends on various parameters such as the type of nonferrous metal or other metal (type of molten metal), various dimensions, temperature, magnetic field strength, current value and other values. Seem.
- the product which the impurity accumulated on the periphery was not able to be obtained.
- the reason is considered to be that the molten metal is more strongly stirred, and impurities that are to be collected around by Archimedes' electromagnetic force are distributed in the molten metal.
- the current density is preferably set to about 10-40 A / cm 2 . Therefore, the amount of current to flow may be changed according to the diameter of the product P.
