    A method and a device are proposed which are used in steel works for casting lead-bearing steel. Lead is used to a large extent in the production of high-speed steel, the consumption of which has steadily increased in recent decades. Two factors have in the meantime led to problems in the production of steel of this type: the low solubility of the metal in the molten pool and the outflow of poisonous gases during the casting of ingots. The use of a distributor is proposed which consists of two parts or chambers. The first chamber, which receives the molten metal directly from the ladle, is designated as feeding chamber (1), open or not open. The second chamber is connected to the first, is closed and sealed off, is cylindrical/conical, is not fed radially and is designated as emptying chamber (2). The lead is added to the metal pool in the emptying chamber (2). The rotary movement of the molten mass, which rotary movement is assisted by the cylindrical/conical form of the emptying chamber (2), results in a uniform distribution of the lead (Pb) in the molten steel. The chamber bases are provided with a slope in order to avoid the formation of solidified deposits at the end of the respective melting charge.
