摘要： Precision casting of titanium or titanium alloy includes establishing molten metal by induction heating in an assembly formed with water cooled copper segments disposed circlewise on the inside of an induction coil in a state insulated from each other and casting the molten metal into a permeable mold by vacuum casting. The precision casting method uses apparatus including an induction coil, an assembly formed with the aforementioned copper segments, an arrangement for feeding a base metal from the under side thereof and a permeable mold into which the molten base metal in the assembly is transferred by vacuum casting. It is possible to obtain precision castings of metal having high melting points and high actvitiy such as titanium, titanium alloy or the like.
