ABSTRACT:
A ladle covered by a lid suitable for carrying out metallurgical reactions, particularly desulphurization, characterized by the fact that the lid is spaced above the ladle so that the edge of the lid overlaps the edge of the ladle, thereby forming an annular slot. A collar open at the top and bottom is inserted in the ladle and is attached to the lid to form outlets for ambient air.
