Abstract

Skimming molten metal (5) from objects comprises immersing the object into a molten metal; moving the object upward from the melt; accelerating a melt stream flowing downward onto the object in an opposite direction to the upward direction of the object; and blasting the melt stream against the object. An independent claim is also included for a device for skimming molten metal from an object comprising inductors (2, 3), in which at least one inductor is immersed in the melt. Preferred Features: The melt stream is passed through a flow gap. The speed of the melt stream in the gap is regulated using different air gaps.
