号）。 The present applicant previously proposed an aluminum refining method that utilizes the principle of segregation solidification in order to produce high-purity aluminum. In this refining method, after the aluminum to be purified is melted, the molten aluminum is always heated and maintained at a temperature exceeding its solidification temperature, and a cooling body is immersed in the heated molten aluminum. By maintaining the surface temperature below the solidification temperature and rotating this cooling body to disperse and mix the impurities discharged near the solidification interface, the thickness of the impurity concentrated layer near the solidification interface in the liquid phase can be reduced. It is characterized by crystallizing high-purity aluminum on the surface of the cooling body while making the cooling body thinner and thereby steepening the temperature gradient in the liquid phase in the impurity-concentrated layer (Japanese Patent Laid-Open No. 57-82437).

は一層向上する。 The continuous manufacturing apparatus for high-purity aluminum according to the present invention includes a melting furnace for melting aluminum and a plurality of crucibles arranged in a row, one crucible being placed in each crucible, and movable up and down. Adjacent crucibles are connected in a continuous manner by a connecting gutter at the upper end, and the molten metal is placed at the upper end of the crucible farthest from the melting furnace. A discharge gutter is installed, and all connecting gutter and molten metal discharge gutter are located on a straight line parallel to the line connecting the centers of the crucibles when viewed from the plane, so that the molten aluminum is discharged from the melting furnace to the crucible closest to the melting furnace. It is designed to be sent. The rotary cooling body is used to crystallize high-purity aluminum on its circumferential surface. That is, after the molten metal is put into each crucible, the rotary cooling body is lowered and immersed in the molten metal, and when it is rotated, high-purity primary aluminum crystallizes on the circumferential surface of the rotary cooling body, and impurities are removed. The impurities are discharged into the liquid phase, but when the rotary cooling body is rotated, relative movement occurs between the solid phase and the liquid phase, and the impurity concentrated layer formed near the solidification interface by the discharged impurities. Stirring and mixing with most of the other liquid phases is performed effectively, and the impurities in the impurity concentrated layer are dispersed throughout the liquid phase, resulting in a very thin impurity concentrated layer. Become. Therefore,
Refining efficiency increases and high purity aluminum can be obtained. As this rotary cooling body, a cylindrical one or a tapered cylindrical one whose diameter is gradually reduced toward the bottom are used. It is more preferable to use a tapered cylindrical cooling body as this makes it easier to recover high-purity aluminum crystallized on the circumferential surface of the cooling body. The cooling body is cooled by feeding a cooling body such as air, argon gas, nitrogen gas, or a mixed liquid of air and water into the cooling body. If the amount of heat supplied to the molten aluminum in the crucible is increased by heating from an external heat source, and if a large amount of heat is removed by cooling the molten aluminum with a cooling body, the solidification rate will decrease, and the cooling body and molten aluminum will be The heat flow between aluminum and aluminum increases, and the temperature gradient in the liquid phase near the solidification interface increases. Therefore, the effect of the rotation of the cooling body described above, that is, the effect of obtaining high-purity aluminum is further improved.

る。 When the molten aluminum advances forward and the rotary cooling body is rotated clockwise when viewed from the plane, the connection gutter and the discharge gutter are placed in positions that are biased to the left of the straight line connecting the centers of the crucibles, and the rotation When the cooling body is rotated counterclockwise when viewed from above, it is placed in a position that is biased to the right end of the line connecting the centers of the crucibles. Therefore, the aluminum oxide generated during the production of high-purity aluminum due to the centrifugal force generated by the rotation of the rotary cooling body flows through the connecting gutter to the crucible in front, and is smoothly removed through the discharge gutter.

とができる。 In such high-purity aluminum production equipment, the cooling body is raised in advance, molten aluminum is supplied from the melting furnace to the crucibles, and after the amount of molten metal in each crucible is equalized, the cooling body is lowered to fill the molten metal. Dip and rotate. Then, the amount of molten metal supplied and discharged is adjusted so that the amount of molten metal in each crucible remains unchanged during operation, and the amount of aluminum crystallized on the circumferential surface of each cooling body is adjusted to be equal. The amount of aluminum crystallized on the circumferential surface of the cooling body can be changed as appropriate depending on the temperature of the molten metal, the rotation speed of the cooling body, the cooling capacity, and the immersion time. The impurity concentration in the molten metal in each crucible increases sequentially from the one closest to the melting furnace to the one farther away. The average impurity concentration in all aluminum obtained by changing the ratio of the total amount of aluminum recovered by each cooling body to the total amount of molten metal supplied (hereinafter, this ratio is referred to as recovery rate) can be changed, and the smaller the recovery rate, the lower the above average impurity concentration. Therefore, by setting the recovery rate to a predetermined value, it is possible to obtain aluminum of higher purity than the original aluminum to be purified supplied from the melting furnace. Moreover, when the recovery rate is kept constant, the more crucibles there are, the more highly purified aluminum can be obtained.

る。 As described above, according to the continuous manufacturing apparatus for high-purity aluminum of the present invention, all the connecting troughs and the molten metal discharge troughs are located on a straight line parallel to the straight line connecting the centers of the crucibles when viewed from above. Therefore, the aluminum oxide generated in the molten aluminum in each crucible during the refining process can be smoothly removed through the connecting gutter and discharge gutter by the centrifugal force generated by the rotation of the rotary cooling body. . If the connecting gutter and discharge gutter are on a straight line connecting the centers of the crucibles, the aluminum oxide will not flow forward smoothly, and if the connecting gutter is on a tangent line common to two adjacent crucibles when viewed from the plane. In some cases, there is a risk that what has flowed into the crucible at one end forward will flow back. According to the device of the present invention, the molten aluminum melted in the melting furnace and supplied to the crucible at the rear end can be smoothly sent to the crucible at the front by the centrifugal force generated by the rotation of the cooling body of the rotor. This makes it possible to continuously and efficiently produce high-purity aluminum.

and a rotary cooling body 4 for crystallizing high-purity aluminum, which is disposed in each crucible 2B to 2E and is movable up and down, so that adjacent crucibles 2B to 2E are The upper end of the crucible 2E is connected in communication with the connecting gutter 5, and the molten metal discharge gutter 7 is attached to the upper end of the crucible 2E that is farthest from the melting furnace 1. A series of high-purity aluminum is placed on a straight line parallel to the straight line connecting the centers of the crucibles 2B to 2E, and molten aluminum is fed from the melting furnace 1 to the crucible 2B closest to the melting furnace 1. Manufacturing equipment.
