Description

Technical Field

[0001] The utility model belongs to the spheroidizing annealing of steel wires, and particularly relates to a steel wire spheroidizing annealing device. Background Art

[0002] Steel wire spheroidizing annealing refers to the process of annealing the steel wire after it is processed into a spherical shape. Annealing is a heat treatment process that changes the crystal structure of materials by heating and cooling, thereby improving the properties of materials. Annealing the steel wire after spheroidizing can improve the toughness and strength of the steel wire, reduce internal stress at the same time, and make the steel wire more uniform and stable. The steel wire treated in this way usually has better mechanical properties and service life.

[0003] The Chinese patent with the publication number of "CN220537854U" discloses a continuous spheroidizing annealing device for bearing steel wires, which includes a shell, a fuel pipeline interface and a high-speed burner. The fuel pipeline interface and the high-speed burner are both arranged on the side wall of the shell. A circulating air inlet pipe and a circulating air outlet pipe are respectively arranged at the bottom and top of the side wall of the shell; A motor is fixedly arranged at the bottom of the shell, and the output end of the motor extends into the interior of the shell and is fixedly provided with a rotating column. A plurality of uniformly distributed hanging rods are fixedly arranged on the column wall of the rotating column, and a plurality of groups of uniformly distributed clamping mechanisms are arranged on the rod wall of the hanging rods; An opening is arranged on one side of the shell, and a shell cover is arranged at the opening. The utility model can spheroidize and anneal the bearing steel wire while rotating inside the shell, improve the uniformity of the spheroidizing annealing of the bearing steel wire, ensure the use quality of the product, and improve the efficiency at the same time.

[0004] During the use of the above device, although it can assist in annealing, there are still certain defects during its overall use. First of all, during its use, the high-speed burner is arranged on one side of the bottom inside the shell. Although it adopts a rotary hanging rack design, the high-speed burner obviously cannot quickly transfer heat energy to the upper end of the hanging rack. It can be seen that during the heating and annealing process, the overall heating uniformity of the material at the upper end of the hanging rack is poor. At the same time, during its use, manual operation is required to take out the steel wire material. However, after the annealing heating is completed, the outer surface of the steel wire has a high temperature. At this time, taking it out manually, the high temperature on the surface of the steel wire is extremely easy to scald the human body. It can be seen that it has certain defects and deficiencies.
