ABSTRACT:
Systems, methods and apparatus for facilitating removal of molten metal from an electrolysis cell are provided. In one embodiment, a system includes a container and an electrical source coupled to the container. The electrical source may be configured to provide complementary current to a spout of the container. This complementary current may create a complementary electromagnetic field at least proximal a tip portion of the spout. When the spout of the container receives the complementary current, and when the spout is in liquid communication with the molten liquid of the electrolysis cell, the complementary electromagnetic field of the complementary current may at least partially assist to increase the flow of molten metal into the spout of the container.
