Definitions

  • EXAMPLE 2 A round steel bar 11 which is 18 mm. in diameter and 230 mm. in length is prepared and two round holes 12 with a diameter of 5.5 mm. are bored therein with a drill throughout the length thereof with a spacing of 8 mm. between the holes (FIG. 2, I). Then, a suitable number of such bored round steel bars 11 are joined in series by welding 13 and the joined portions being bored to break through the round holes 12 (FIG. 2, II). It is then annealed and drawn. The drawing operation is effected at a temperature of ZOO-300 C., using a lubricant oil, in several steps, followed by an intermediate annealing and it is finally worked into a long-sized round steel bar 14 having a diameter of 10.5 mm.
