Abstract
Apparatus and method for alloying continuously cast steel products wherein a wire of alloying material, e.g. lead, is fed through the center of the stopper rod to its nose where the wire melts and dissolves into the stream of liquid steel flowing out of the tundish. The guide passage for the wire and a cooperating hole in the nose of the stopper rod are temporarily closed by heat meltable means which prevents steel from entering and clogging the hole in the passage before a steady-state flow condition is achieved.
