Abstract

A device for forming a molten solidified body by receiving a molten material discharged from a vitrification device or the like on a lower mold, and a method for forming a molten solidified body and, particularly, to a mold supporting device for forming a uniform molten solidified body such that a height deviation on a mold of a dropping molten material is reduced by providing movement to the mold, and a method for forming an uniform molten solidified body. The mold supporting device and the method for forming a uniform molten solidified body to prevent the formation of a high columnar shape at a specific position by the molten effluent not being uniformly contained in the mold due to the high viscosity thereof, thereby forming a uniform solidified body.

First claim

The invention claimed is:

1. A mold supporting device for forming a molten solidified body, comprising:
a molten solidified body mold, which receives a molten effluent at a lower part of a melt discharge outlet of a melting furnace and forms a solidified body;
a horizontal mold movement part for providing the mold with horizontal movement within a certain range, the horizontal mold movement part being disposed on a lower part of the molten solidified body mold and comprising an X axis movement part and a Y axis movement part that are moved in combination so that a position of the molten solidified body mold is altered freely within a predetermined range on a horizontal plane, wherein, when the molten effluent is discharged, the horizontal mold movement part is configured to shift the mold in a horizontal positional direction such that a position onto which the molten effluent drops varies; a mold supporting part, which supports the molten solidified body mold from the lower part of the molten solidified body mold; and
a vertical mold movement part comprising a Z axis movement part, wherein:
the Z axis movement part is configured to, when the molten effluent is discharged, shift the mold in a vertical positional direction such that a height of the mold relative to the lower part of the melt discharge outlet varies, and
the mold is configured to adjust the position onto which the molten effluent drops such that the position is located at a height lower than a height of a previously-discharged molten effluent.

2. The mold supporting device of claim 1 , further comprising a rotational movement part that rotates the molten solidified body mold.

3. The mold supporting device of claim 1 , comprising a mold movement control part that controls the movement of the horizontal mold movement part such that a height of the molten effluent from the melting furnace becomes uniform.

4. The mold supporting device of claim 1 , wherein the mold supporting device is configured to use at least one of the horizontal mold movement part and the vertical mold movement part to effect at least one of the horizontal position shift of the mold and the vertical position shift of the mold such that a movement route of the discharging of the molten effluent does not result in deposition of the effluent on a highest point of the previously-discharged molten effluent.

5. The mold supporting device of claim 3 , wherein the mold supporting device is configured to measure the height of the previously-discharged molten effluent to control the movement of the horizontal mold movement part.

6. The mold supporting device of claim 5 , wherein the mold supporting device is configured to measure the height at a number of measurement positions of the previously-discharged molten effluent, wherein the number of measurement positions is at least two.

7. The mold supporting device of claim 6 , wherein the mold supporting device is configured to cause the mold to drop the molten effluent onto a lowest position of the measurement positions.

8. The mold supporting device of claim 6 , wherein the mold supporting device is configured to implement a movement route of the mold to avoid a highest position of the measurement positions.
