Product Introduction
Xuanyu Springsis a professional manufacturer of hot-rolled springs for mining equipment. We focus on providing highly reliable, long-life cushioning and support spring solutions for core heavy-duty equipment in the mining industry.
Hot-rolled springs for mining equipment are heavy-duty cushioning components specifically designed for mining machinery. They are hot-rolled at high temperatures of 850-1050℃ and undergo overall quenching and tempering treatment, enabling them to withstand impact loads up to 500kN . These springs effectively address the industry pain point of "short lifespan of ordinary springs in harsh mining environments," providing reliable elastic support and cushioning protection for critical equipment such as crushers, vibrating screens, and mine cars.

Core Advantages of Xuanyu Mining Equipment Hot-Rolled Springs
1.Materials and processes reinforced for extreme impact conditions
The core is made of 60Si2Mn spring steel, and undergoes precise high-temperature hot rolling and quenching and tempering heat treatment. This combination of processes enables the springs to have a higher elastic limit and resistance to permanent deformation when subjected to the high-frequency, high-impact loads unique to mining equipment, thereby improving durability from the root.
2.Excellent long lifespan and resistance to degradation
Through optimized heat treatment and control, our springs can maintain an elastic decay rate of ≤3% after 100,000 strong impact cycles. This translates to longer replacement cycles, lower maintenance costs, and consistently stable equipment cushioning performance, directly addressing the industry challenge of "short lifespan."
3.Specific surface protection for mining environments
We employ a dual protection system of "sandblasting for rust removal + epoxy resin coating". This technology not only effectively resists the severe abrasion from slag, but also forms a durable anti-corrosion layer in the humid mine environment, significantly improving the spring's environmental adaptability under harsh working conditions.
4.Customized design and support based on deep understanding
We have in-depth knowledge of the operating conditions and failure modes of various mining equipment (such as jaw crushers and vibrating screens). We can provide full-process engineering support, from selection calculations and prototype testing to mass production, tailored to your specific equipment model, load curve, and installation space, ensuring a perfect match between the springs and the equipment.
