Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to a high-strength bolt wire material spheroidizing device. Background Art

[0002] Bolts made of high-strength steel or that require a large preload can be called high-strength bolts. High-strength bolts are mostly used for the connection of bridges, rails, high-pressure and ultra-high-pressure equipment. The fracture of this type of bolt is mostly brittle fracture. High-strength bolts used in ultra-high-pressure equipment require a large preload to ensure the sealing of the container.

[0003] In order to improve the plasticity and toughness of the wire, the wire raw materials are usually subjected to spheroidizing annealing before the production of high-strength bolts. At present, when the wire raw materials are subjected to spheroidizing annealing, the wire is directly hoisted in the spheroidizing annealing furnace. During the heating process of the wire, it cannot fully contact the heat source, resulting in uneven heating of the wire, and the heating device needs a long time to heat the wire.
