Description

Technical Field

[0001] The utility model belongs to the technical field related to the processing of spring steel wires, and particularly relates to a processing device for the fatigue performance of high-strength spring steel wires. Background Technique

[0002] The fatigue performance of high-strength spring steel wires can be improved through appropriate heat treatment processes. Quenching is a step in the heat treatment process, which can increase the hardness and strength of the material, thereby improving the fatigue performance to a certain extent. However, quenching treatment may also introduce residual stresses, which, if not eliminated by appropriate tempering treatment, may reduce the fatigue life of the material. Therefore, tempering treatment is usually carried out after quenching to optimize the microstructure of the material, reduce residual stresses, and improve the fatigue performance.

[0003] In practical engineering applications, the heat treatment process of high-strength spring steel wires may include various different steps, such as protective atmosphere heat treatment, quenching and tempering, surface heat treatment, etc. The combination of these processes can be adjusted according to specific material characteristics and application requirements to obtain the best fatigue performance. In addition, some studies have explored special heat treatment processes such as austempering to further improve the strength and plasticity of spring steel, and these processes also help to enhance the fatigue performance.

[0004] In summary, quenching is indeed an effective means to improve the fatigue performance of high-strength spring steel wires, but it needs to be combined with other heat treatment steps and consider the specific conditions and application scenarios of the material.

[0005] However, harmful gases are indeed generated during the quenching process of spring steel wires. These gases mainly include sulfides, nitrides, carbon monoxide, carbon dioxide, and particulate matter, etc. If these waste gases are directly discharged without treatment, they will cause serious impacts on the environment and human health.
