Product Description

Product Description

Coil springs are key element of suspension on rolling stock. It is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. It can be divided into primary suspension also called journal box spring, and secondary suspension also called bolster spring.

 

Product Features
1. Surface Treatment: Employ ultrasonic or high - load rolling before hot rolling to tackle spring decarburization, and utilize high - pressure water jets to prevent stress - related fatigue.
2. Microstructure Regulation: Propose new heat - treatment processes such as slow - cooling followed by rapid quenching to enhance strength, and Q - I - Q - T (Quenching - Intercritical - Quenching - Tempering) for improved cold - forming performance.
3. Processing Technology: Optimize roller design to reduce twisting, use automatic equipment to ensure flatness, and eliminate secondary martensite brittleness after heat treatment.
4. Production Line Construction: Collaborate to develop a full - function automatic rolling line, aiming to improve spring precision, automation level, and production efficiency.
