Abstract
A device and a method for changing at least one electrode of a melt-metallurgical vessel which has a receiving device for molten metal and a vessel cover with one opening per electrode for covering the receiving device. The at least one electrode can be positioned by means of at least one electrode support. The electrode and its support, and optionally the vessel cover can be lifted and laterally pivoted about a perpendicular rotational axis by a lifting and pivoting device. At least two electrode changing stations next to the receiving device are either adjacent to each other on a circular path about the rotational axis in a pivot range of the lifting and pivoting device or can be alternately brought onto the circular path about the rotational axis in the pivot range.
