Abstract

A container does not need a member such as a stoke and the like that are exposed to the molten metal therein, thus the necessity to replace the parts such as the stoke and the like can be eliminated. In addition, there is no structure like the stoke in the container, the operability for the preheating is improved thus the preheating can be performed effectively. In addition, since a flow passage is formed inside the lining with high heat conductivity, inner heat of the container is easily conducted to the flow passage. Thus, the decrease in temperature of the molten metal that flows inside the flow passage can be suppressed to the utmost.

Claims

1. A container for introducing molten metal to an inside of the container, for transporting the molten metal to a use point by a delivery vehicle, and for supplying the molten metal to an outside of the container at a use point by using a pressure difference, the container comprising:

a frame;

a first lining disposed inside the frame, having a passage capable of flowing the molten metal, the first lining having a first thermal conductivity, the passage is formed in the first lining from a position close to a bottom portion of the container to an upper portion of the container;

a second lining disposed between the frame and the first lining, the second lining having a second thermal conductivity lower than the first thermal conductivity; and

a cylindrical pipe having a first end and a second end, the first end of the pipe being

connected to an upper portion of the passage, the cylindrical pipe being bent so that the second end of the cylindrical pipe is directed downwardly.

2. A container according to claim 1, wherein an inner diameter of the passage is approximately 65 mm to approximately 85 mm.

3. A container according to claim 2,

wherein the container has a first opening disposed at an upper portion thereof,

wherein the container further comprises a lid detachably disposed to cover the first opening of the container, the lid having a second opening with a diameter smaller than that of the first opening, and

wherein the container further comprises a hatch disposed over an upper surface of the lid, the hatch being capable of opened and closed, the hatch covering the second opening, the hatch having a through hole by which the

inside of the container communicates with the outside of the container, the through hole being for adjusting an inner pressure of the container.

9. A container according to claim 1, wherein the passage capable of flowing the molten metal is cylindrical.

10. A container according to claim 1, wherein the second end of the cylindrical pipe is capable of discharging the molten metal.

4. A container for introducing molten metal to an inside of the container, for transporting the molten metal to a use point by a delivery vehicle, and for supplying the molten metal to an outside of the container at theuse point by using a pressure difference, the container comprising:

a frame made of metal, covering outer circumference of the container;

a storing room for storing the molten metal;

an interface portion as a passage for the molten metal between the storing room and the outside of the container, the interface portion having a communicating opening at a lower portion of the interface portion for communicating with a lower portion of the storing room;

a wall partitioning the storing room and the interface portion; and

a cylindrical pipe connected to an upper portion of the interface portion,

wherein a first lining and a second lining are layered between a region of the storing room and the interface portion and the frame with the first lining being inward, the first lining having a first thermal conductivity, the second lining having a second thermal conductivity lower than the first conductivity, and

wherein the wall has a zone filled with the first lining from the communicating opening to the upper portion of the interface portion such that the interface portion is kept warm by the second lining disposed between the interface portion and the frame, and that the thermal conduction from the molten metal stored in the storing room to the interface portion is promoted via the zone, and

wherein the cylindrical pipe is bent so that one end of the cylindrical pipe is directed downwardly.

5. A container according to claim 4, wherein an inner diameter of the interface portion as the passage is approximately 65 mm to approximately 85 mm.

6. A container according to claim 5,

wherein the container has a first opening disposed at an upper portion thereof,

wherein the container further comprises a lid detachably disposed to cover the first opening of the container, the lid having a second opening with a diameter smaller than that of the first opening, and

wherein the container further comprises a hatch disposed over an upper surface of the lid, the hatch being capable of opened and closed, the hatch covering the second opening, the hatch having a through hole by which the inside of the container communicates with an outside of the container, the through hole being for adjusting an inner pressure of the container.

11. A container according to claim 4, wherein the end of the cylindrical pipe opposite the end connected to the interface portion is directed downwardly and is capable of discharging the molten metal.

7. A container for storing a molten metal and for introducing the molten metal to an inside of the container or for supplying the molten metal to an outside of the container by using a pressure difference, the container being delivered to a use point by a delivery vehicle, the container comprising:

a frame;

a lining inside the frame, having a communicating opening close to a bottom portion of the container, the lining having therein a passage from the communicating opening to a pipe mounting portion disposed at an upper portion of the container, an inner diameter of the passage being approximately 65 mm to approximately 85 mm; and

a pipe mounted at the pipe mounting portion for communicating with the passage.

8. A container according to claim 7,

wherein the container has a first opening disposed at an upper portion thereof,

wherein the container further comprises a lid detachably disposed to cover the first opening of the container, the lid having a second opening with a diameter smaller than that of the first opening, and

wherein the container further comprises a hatch disposed over an upper surface of the lid, the hatch being capable of opened and closed, the hatch covering the second opening, the hatch having a through hole by which the inside of the container communicates with the outside of the container, the through hole being for adjusting an inner pressure of the container.

12. A container according to claim 7, wherein the passage is cylindrical.

13. A container according to claim 7, wherein the pipe mounted at the pipe mounting portion is cylindrical.

14. A container according to claim 7, wherein the pipe is capable of discharging the molten metal.
