Abstract

PURPOSE:To produce powder of Ti metal without any contamination with vessel material, etc., by boring bottom wall of a crucible by electron beam after melting the active metal of Ti, etc., in a water cooled dividing type copper- made crucible by high frequency induction power and flowing down the molten Ti on a disk rotating at high speed. CONSTITUTION:The active metal 20 of Ti, etc., is charged into the crucible 4 cylindrically assembling multiple copper segments 7 having introducing pipe 10 for cooling water in there as inserting insulating material 8 at intermediate and by conducting the high frequency current, for example 100kHz, to the high frequency induction coil 3 arranged at outer periphery of the crucible, the Ti 20 is heated and melted by the induction power. As the crucible 4 is water cooling type, the solidified shell 19 of Ti is developed in inner part thereof, and the molten Ti 20 in the crucible 4 is not contaminated with the crucible material. The bottom part of the crucible 4 is constituted with Ti plate and the electron beam from an electron gun 5 is turned upward through a deflecting coil 6, to bore a hole 13 on the Ti-made bottom wall 9 of the crucible 4, and the molten Ti is flowed down on the disk 12 rotating at high speed to produce the Ti powder having high purity.
