Transfer type plasma heating anode

A transferred plasma heating anode for heating a molten metal in a container by applying an Ar plasma generated by passing a direct current through the molten metal, the transferred plasma heating anode comprising;

• an anode, composed of a conductive metal, that has an internal cooling structure,
• a metal protector having an internal cooling structure that is placed outside the anode with a constant gap between the anode and the protector, and
• a gas supply means that supplies an Ar-containing gas to the gap, is characterized by,
• the whole of the external surface of the anode tip end being inwardly recessed.

• an anode, composed of a conductive metal, that has an internal cooling structure,
• a metal protector having an internal cooling structure that is placed outside the anode with a constant gap between the anode and the protector,
• a first gas supply means that supplies an Ar-containing gas to the gap therebetween, and
• a second gas supply means in the interior of the anode, is characterized by,
• the second gas supply means having a function of blowing a gas from the external surface of the anode tip end.
