Abstract
Metals are smelted properly. An electrolytic smelting furnace includes a furnace body, a furnace bottom electrode provided at a bottom part in the furnace body, and an upper electrode provided above the furnace bottom electrode in the furnace body, and the upper electrode includes a conductive compound with a spinel-type structure.
Claims22
An electrolytic smelting furnace comprising:
- a furnace body;
- a furnace bottom electrode provided at a bottom part in the furnace body;
- and
- an upper electrode provided above the furnace bottom electrode in the furnace body, the upper electrode including a conductive compound with a spinel-type structure.

An electrolytic smelting furnace comprising:
- a furnace body;
- a furnace bottom electrode provided at a bottom part in the furnace body;
- an upper electrode provided above the furnace bottom electrode in the furnace body;
- a power supply unit that applies voltage between the furnace bottom electrode and the upper electrode;
- and
- a voltage control unit that controls the voltage applied by the power supply unit, the voltage control unit setting a value of the voltage based on a type of an object to be smelted.
3 more elements
An electrolytic smelting furnace comprising:
- a furnace body in which an electrolytic solution is stored;
- a furnace bottom electrode provided at a bottom part in the furnace body;
- an upper electrode provided above the furnace bottom electrode in the furnace body;
- a heating unit that heats and melts a smelted object;
- and
- a moving mechanism that moves the upper electrode, wherein when the smelted object is heated by the heating unit, the moving mechanism places the upper electrode at a position where the upper electrode is not immersed in the electrolytic solution.
