摘要： 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.

摘要： A process and charge material prepared thereof for metallugical fusion processes is disclosed. In the process, at least two alloy components are combined in a nonreactive atmosphere. A support is provided which is made of at least one of the components and the other component is condensed from a vapor phase onto the support to form a condensate. The support is positioned in a holding means in the vapor phase of the alloy component and may be either a plurality of hollow tubes or a foil rolled through the vapor phase from a supply roll to a take-up roll.
