Abstract: PURPOSE: To prevent generation of defects in a wire during a drawing process following to a roll forging process, at drawing through a die a thin wire of such a high melting poit metal as tungsten, by controlling the pressure and velocity of a chuck holding the end of a rod material to a prescribed range.  
     CONSTITUTION: An ingot is prepared by pressing and sinterng a high melting point metallic powder; this ingot is then subjected to a roll forging process so as to successively reduce the diameter; then, thus prepared rod is drawn through a die into a wire in a prescribed diameter. In this wire drawing process, Aqua-dag is applied to the rod surface, and the rod is heated; then, the hot rod is drawn through a sintered carbide die in order to reduce its diameter gradually; hereupon, if the pressure of chucking the rod end is weak, the wire drawing is impractical, whereas, is the pressure is too high, the rod surface is injured with many defects. If the wire drawing speed is slow, the friction increases and causes cracks, whereas, if the speed is too high, the rod end is hurted with many defects.
