Abstract
There are provided an apparatus and a method for manufacturing a copper-base alloy. The apparatus includes an alloying spout, at least one feeder and a tundish. The tundish is inclined downwardly from one end toward the other end for flowing a molten copper therethrough. The feeder is connected to the alloying spout for introducing at least one solid solute constituent into the alloying spout. The method includes the steps of providing the above apparatus, continuously introducing the molten copper from the inlet into the passageway of the alloying spout and causing the molten copper to flow downwardly through the passageway to the outlet, and continuously introducing the solid solute constitutent into the passageway of the alloying spout through the feeder to mix the solute constituent with the molten copper to produce the copper-base alloy.
