Abstract (en)

Systems for centrifugally casting a highly reactive titanium metal including a cold wall induction crucible for containing a titanium metal charge, the induction crucible having a plurality of induction coils and a removable bottom plate, a power source to heat the titanium metal charge in the induction crucible to obtain a molten metal, a preheated secondary crucible for catching the molten metal as it falls from the induction crucible after the removable bottom plate has been withdrawn and the power source turned off, and a centrifugal casting machine for holding and accelerating the secondary crucible to centrifugally force the molten metal into a casting mold and produce a cast component.
