The processing process of spring steel wire is long and complicated, and improper operation of each process will cause influence. The steel wire has many years of practical experience in processing and production. We have summarized the following factors that affect the toughness of steel wire:
1. The toughness of spring steel wire depends on the lead quenching process and the obtained sorbite structure. The flake-shaped sorbite structure can withstand severe deformation. During the drawing process of the steel wire, the sorbite is extended closer to each other. By adjusting different heat treatment processes, the sorbite is uniformly refined, thereby improving the torsion ability.
2. In the process of steel wire heating, when the temperature exceeds 200 degrees, the toughness decreases. In the high temperature season, the heating temperature should be reduced to improve product quality.
3. During the production process, the influence of the residual stress of the spring steel wire should be improved, and the measures to reduce or reverse the drawing should be reduced. The drawing die should be selected to ensure the lubrication condition, thereby reducing the influence of the residual stress and ensuring the toughness of the product.
4. The anti-rust temperature of the finished product should not exceed 10 degrees. After the spring steel wire leaks oil, use room temperature oiling to ensure that the toughness of the steel wire is not affected.
Through years of production practice, Haoxin steel wire has a complete production process, which greatly improves the toughness of spring steel wire and improves production efficiency.
