Abstract | The invention discloses a two-segment type power electric heating softening annealing technology. An electric quenching device is used for replacing a continuous type roller bottom annealing furnace to carry out softening annealing on a high-temperature alloy cold drawing billet; after the cold drawing billet is subject to tip twisting, the section size of the tip is small, the resistance is large, the temperature rise of the portion is higher than that of the other portions, and overburning or tip breaking of the billet is caused. In order to solve the overburning and tip breaking problems, and avoid the yield decreasing generated by repeated tip cutting, a two-segment type power electric heating technology is adopted, low-power preheating is carried out, the twisted tip portion and the other portions of the billet are subject to temperature synchronous constant treatment, high-power electric heating is carried out, after the billet reaches the temperature, rapid water quenching is carried out, through the t |
