Abstract

The invention relates to a process for incorporating additives in molten metal by bottom addition so as to ensure exposure of the additive to the molten metal at a predetermined time and to avoid premature and possibly dangerously violent reaction between the metal and the additive. The additive is placed in the bottom of the ladle which is to contain the metal and is covered with a layer of an inert material which protects the additive until the cover is disturbed.
