- Design and Installation of Plasma Arc Melting Apparatus.
説明
Plasma arc melting apparatus having very low leak rate was designed and installed for melting and casting of reactive metal based intermetallic compound such as TiAI or Nb 3A1.<BR>It is equipped with one plasma torch of maximum output of 20 kW in continual operation and can be operated under adjusted pressure ranged from 6, 000 to 101, 325Pa using inert gas such as Ar or Ar-He mixture.<BR>To verify the leak rate of this apparatus, titanium is melted and the contents of oxygen and nitrogen in titanium was monitored.<BR>Approximate 80g of titanium was melted on the copper crucible under 70V of plasma arc voltage, 130A of arc current and 60 kPa of high purity argon gas.<BR>The increasing rate of nitrogen in titanium determined by chemical analysis was 0.05ppm/s and agreed with that calculated from the leak rate measured.
