Abstract
A metal product manufacturing device is provided to remove, with higher accuracy, impurities from a molten metal of a non-ferrous metal or another metal containing the impurities, obtain the molten metal having higher purity, and obtain a high-purity non-metal product or another metal product from the high-purity molten metal.
Claims11
A metal product manufacturing device including a container that stores a molten metal having a conductive property, the metal product manufacturing device comprising:
- a cylindrical container body portion;
- an upper end plate and a lower end plate configured to close both ends of the container body portion in a sealed state;
- an upper electrode fixed to the upper end plate in a state of passing through the upper end plate, and having an inner end electrically connectable to the molten metal;
- and
- a lower electrode fixed to the lower end plate in a state of passing through the lower end plate, and having an inner end electrically connectable to the molten metal, wherein
- at least the upper end plate is detachable from the container body portion,
- the upper electrode is fixed to a substantially central portion of the upper end plate in the state of passing through the upper end plate in a thickness direction,
- the lower electrode is fixed to a substantially central portion of the lower end plate in the state of passing through the lower end plate in a thickness direction, and
- the upper electrode and the lower electrode are located on a substantially vertical straight line in an upper-lower direction.
A metal product manufacturing method of manufacturing a metal product from a molten metal having a conductive property, the metal product manufacturing method comprising:
- preparing a container that includes:
- a cylindrical container body portion;
- an upper end plate and a lower end plate configured to close both ends of the container body portion in a sealed state;
- an upper electrode fixed to the upper end plate in a state of passing through the upper end plate, and having an inner end electrically connectable to the molten metal;
- and
- a lower electrode fixed to the lower end plate in a state of passing through the lower end plate, and having an inner end electrically connectable to the molten metal, wherein
- at least the upper end plate is detachable from the container body portion,
- the upper electrode is fixed to a substantially central portion of the upper end plate in the state of passing through the upper end plate in a thickness direction,
- the lower electrode is fixed to a substantially central portion of the lower end plate in the state of passing through the lower end plate in a thickness direction, and
- the upper electrode and the lower electrode are located on a straight line in an upper-lower direction;
- making the metal having the conductive property and stored inside the container into a state of a molten metal while the container is sealed by the upper end plate and the lower end plate;
- electrically connecting the inner ends of the pair of electrodes to the molten metal having the conductive property;
- and
- applying a current between the pair of electrodes in this state.
