DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying a product number of an ingot for displaying a product number or other product on an ingot such as a billet or a slab, which is a material such as an extruded aluminum material, and a display structure thereof.

[0002]

2. Description of the Related Art Product labeling of this type of ingot serves as an index for production control of ingots, and particularly reaches hundreds of ingots per day.
Also, under a production management system using a computer, the importance of this product display is high, and it is important that the product be displayed accurately and easily so that it can be easily recognized.

[0003] Conventionally, such a product display, for example, in the case of a billet (cylindrical ingot), is directly handwritten on the bottom surface with ink or the like, or directly stamped using a punch or a simple automatic marking machine. I went there.

[0004]

However, when handwriting is performed with ink or the like, the work is not so troublesome, but it may disappear due to friction or the like unless the handling is particularly careful. In some cases there was a problem.

[0005] In the case of stamping with a punch, although it is unlikely to disappear due to friction, it takes time and labor, and even if the stamping is carried out, the stamping must be repeated due to irregularities in the stamping or partial strength of the stamping. In some cases, there was considerable work burden.

[0006] In the case of an automatic stamping machine, the above-mentioned friction is less likely to disappear, and it does not take much time. Depending on the state, there is also a problem that the strength of the engraving appears, making it difficult to recognize. Also,
In either case, the above-mentioned defect is likely to occur, so that the engraved number is likely to be wrong.

Therefore, the present inventor has proposed a method in which a product is indicated by a separate member instead of directly drawing or engraving on the ingot surface as described above which has been performed for a long time until now. Another object of the present invention is to provide a method of displaying a product display of an ingot and a display structure thereof, which can easily and accurately display a display that is easy to recognize.

[0008]

In order to solve the above-mentioned problems, a product display of an ingot according to the present invention is provided such that a display surface of a member in which a product display is made in advance contacts a bottom surface or a side wall surface of an ingot casting mold. By disposing the member at a predetermined position of the mold, pouring the molten metal into the mold, cooling, and casting, the product can be displayed as an ingot.

[0009] The display structure of the ingot, which can be displayed by the above-described display method, is such that a member having a melting point higher than that of the metal and at least a product label is displayed on the ingot surface of the metal ingot. Is embedded and mounted such that the display surface is exposed.

[0010]

A desired object can be achieved by arranging a member indicating a product of an ingot in a mold and performing casting.

[0011]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an example of a method for displaying a product of an ingot according to the present invention;

As shown in FIG. 1, an aluminum billet 1 having an ingot product display structure according to the present invention comprises a plate 4 on which a product display 3 is engraved in advance, and a product display 3 side abutting against a bottom surface of a mold. It can be manufactured by placing it in place and pouring molten aluminum into the mold, then cooling and casting. The billet 1 manufactured in this manner can have a configuration in which the plate 4 is embedded and mounted on the bottom surface 2 and only the product display 3 is exposed.

Incidentally, instead of the bottom surface as described above, it is also possible to arrange the product display 3 side in contact with the side wall surface. Further, when the plate 4 is disposed on the mold, the final confirmation of the product display 3 can be performed by confirming the product display 3.

The shape of the plate 4 is not limited to a rectangular shape, and may be any shape such as a circular shape or an elliptical shape. As shown in FIG. In the case of a billet 1 as shown in FIG. 3, if at least the thickness of the opposing side surface is a tapered end surface shape whose inner side is larger than the engraved side, as shown in FIG.
It is preferable that the plate 4 does not fall off the plate.

The material of the plate 4 is a member having a melting point higher than at least the melting point of the cast metal, ie, aluminum, and may be a member having a hardness such that it can be easily engraved. In the case of product display, aluminum is preferred.

The product display 3 is a character, a symbol, a number, or a combination thereof, such as a product number, a production date, or a production factory name, for which production management can be suitably performed, and a product recognition display such as a bar code. It is possible. The indication can be stamped on one side of the plate 4 by hand using a punch or by an automatic stamping machine. This engraving operation can be performed on a desk, but can be performed while checking the process in a process independent of the casting process.

This structure is the same not only for aluminum billets, but also for plate-like ingots (slabs) and other metals.

[0018]

According to the present invention, as described above, the product can be clearly displayed as in the case of ingot production. Since it can be performed in a process separate from the production work of product display members and casting of ingots, and also on a desk, work can be performed at the most efficient time considering work efficiency, and the work itself is easy to do In addition, since it is possible to work more carefully, a display that is more easily recognizable is possible.

Further, since the product display can be repeatedly confirmed during the casting manufacturing process, the product display without error can be performed.
