抄録

An industrial scale new melting process, named Plasma Progressive Casting Furnace (PPC-F) was designed and constructed by Daido Steel Co., in Daido's Hoshizaki Plant. This process is suitable for making a titanium primary ingot (VAR electrode) directly from grain sponge and/or various shapes of scraps without requirement for compaction and electrode fabrication. The furnace has six plasma torches circling around the water cooled crucible. Plasma arcs are controlled by magnetic field which also makes molten pool rotate. Materials are fed and melted continuously and solidified ingot is withdrawn progressively.<br>This process has a distinctive advantage of efficient utilization of small sized scraps which is difficult to remelt in usual VAR process and a high reduction of the melting cost is accordingly expected.
