ABSTRACT:
Method for the charging and controlled addition of prealloys to molten alloys of metals reactive and nonreactive at room temperature which are held in a crucible. To permit pre-alloys with a high percentage of reactive metal to be worked more easily, a casting is produced from the reactive and nonreactive metals by a casting process followed by solidification. This casting is nonreactive at its surface at room temperature and its average content of reactive metal is equal to or greater than the reactive metal content in the crucible. Such castings are added to the crucible according to the need for the reactive metal. In an especially advantageous manner, a casting produced in a casting mold in a nonreactive atmosphere has at least at its surface such a content of nonreactive metal that it is stable at room temperature.
