Description

TECHNICAL FIELD The present invention relates to a casting mold leveling jig for obtaining an anode having a good shape capable of stabilizing an electrolysis process in an anode casting process for copper electrolysis in a copper smelting operation.

The anode of about 98% of copper grade cast in the anode casting process for copper electrolysis in the copper smelting operation is finished into electrolytic copper of about 99.99% copper grade in the electrolytic process of the next step, and is made into a product. It is known that the shape of the anode produced in the casting process has a great influence on the stability of the operation in the electrolysis process.

The shape of the anode required to stably operate the electrolysis process is that the thickness is uniform, the surface is smooth, the outer edge of the anode is not cast or bulged, etc. For the reason shown in

1 and 2 are schematic views showing an anode and a cathode charged in an electrolytic cell. As shown in FIG. 1, in the electrolysis process, the anode 1 and the cathode 2 are alternately inserted into an electrolytic cell (not shown), and electrolytic smelting is performed. The copper that has melted from the anode 1 is electrodeposited on the cathode 2, and then the cathode 2 that has been subjected to electrolytic smelting is lifted from the electrolytic cell, washed, bound to a predetermined number, and stored as a product.

The ideal positional relationship between the anode 1 and the cathode 2 during electrolytic smelting is that the anode 1 and the cathode 2 referred to as the interelectrode distance 3 in a state of being suspended vertically in the electrolytic cell as shown in FIG. Is equally adjusted on any face of the anode 1 and cathode 2 facing each other. This is because if the anode 1 and the cathode 2 maintain the above-described ideal positional relationship, the local electric resistance can be prevented from being lowered or short-circuited, so that the electrolysis process can be stably operated. .

Therefore, in order to make the inter-electrode distance 3 equal, as described above, the anode 1 is uniform in thickness, the surface thereof is smooth, and the outer edge portion of the anode 1 is cast into a shape without casting or swelling. There is a need.

Among the required anode shapes listed above, the smooth surface and the absence of casting or swelling at the outer edge of the anode are not suitable even after the anode casting process, even if an anode with an unfavorable shape is cast. The shape can be corrected by relatively light grinding or the like. In addition, for example, Patent Document 1 discloses a method of suppressing the occurrence of casting by providing a stainless steel plate at the top of the anode mold. Is published. Further, for example, Patent Document 2 discloses a method for suppressing the occurrence of blistering by measuring the anode surface temperature distribution, and Patent Document 3 refers to waist folding by sufficiently cooling the anode. A method for suppressing the occurrence of bending of the anode is disclosed.

On the other hand, regarding the required shape of the anode, regarding the uniform thickness, when an anode with an unfavorable shape has been cast, it is necessary to modify the shape by relatively heavy grinding over the entire surface of the anode. Therefore, it becomes difficult to correct both in terms of efficiency and cost. Therefore, in the anode casting process, casting an anode having a uniform thickness is very important for stable operation of the electrolysis process.

FIG. 3 is a schematic view showing an anode casting facility. The anode casting equipment used in the anode casting process is that a plurality of copper molds 5 are placed on a turntable 4 which is a mold conveying equipment, and the mold 5 is rotated while rotating the turntable 4 in a predetermined rotation direction 6. Conveyed continuously, the molten copper is cast into the mold 5 from the rod 7, the molten copper is solidified by the cooling device 8 to cast the anode 1, and then the anode 1 is stripped by the stripper 9. . For simplification, the number of molds is 6 in FIG. 3, but the number of molds is usually about 18.

In the anode casting process, in order to produce an anode having a uniform thickness, it is necessary to keep the mold horizontal and make the depth from the molten metal surface to the casting surface the same at any position of the mold. A leveling jig is used for leveling.

FIG. 4 is a schematic view showing a state in which the mold 5 is horizontally adjusted using a conventional casting mold leveling jig 12. In FIG. 4, the mold 5 is set on a gantry 11 fixed on the turntable body 10, and an iron plate-like leveling jig 12 is sandwiched between the bottom of the mold 5 and the gantry 11 on the right side in the figure. The anode 5 having a uniform thickness is manufactured by horizontally adjusting the mold 5 and holding the mold 5 horizontally.

However, when the rotational movement on the turntable 4 or when the anode 1 is peeled off, the mold 5 vibrates, and the leveling jig 12 may be displaced or detached, and the levelness may be lost. Therefore, there has been a demand for an adjustment jig that can be corrected to the above and can stably maintain the state in which the mold 5 is horizontally adjusted.
