Production Process of Spring Steel Wire
Material Selection and Pretreatment: At Tianjin Kaishuo Weiye Steel Co., Ltd., we commence our Production of Performance Steel Spring Wire with a meticulous choice of top-grade high carbon or alloy steel, revered for its excellent elasticity and formidable strength. During pretreatment, we employ precise heating and rolling techniques to meticulously refine the microstructure, dramatically enhancing the mechanical properties. This foundational step is pivotal in ensuring that our wire maintains its unwavering quality and superior performance, meeting the highest industry standards.
Step One
Surface Treatment: In this essential stage, we leverage advanced techniques such as acid pickling phosphating or expertly chosen mechanical methods to eliminate iron oxide scale, establish a protective phosphating film, or achieve an impeccably smooth finish. For spring steel wires that demand extraordinary fatigue life, such as those used in valve spring applications, coil peeling is an indispensable practice to significantly reduce surface imperfections, ensuring the product's longevity and reliability.
Step Two
Wire Drawing: This sophisticated process involves artfully reducing the steel wire's diameter through multiple stages of cold drawing, which substantially bolsters its strength and hardness. For Performance Steel Spring Wire requiring enhanced robustness, it is crucial to maintain the outlet temperature below 150 ºC throughout each drawing pass to prevent strain aging and torsional cracks. Effective lubrication and cooling are paramount to managing the heat generated during this process, ensuring optimal performance and durability.
Heat Treatment: This pivotal phase encompasses quenching and tempering to refine the wire's structure and properties. Carbon steel spring wires typically undergo lead bath quenching to achieve a refined pearlite structure, while alloy steel wires benefit from precise annealing heat treatments. Stainless steel wires are processed using advanced solid solution techniques, and oil quenching may incorporate water or polymer-enhanced quenching for superior results, ensuring the wire's exceptional performance in demanding applications.
Step Three
Forming: Utilizing state-of-the-art precision equipment, we adeptly shape the drawn steel wire into a variety of spring configurations, such as compression springs and tension springs. These are meticulously crafted to meet the diverse and exacting application requirements, showcasing our commitment to versatility and customization in product offerings.
Inspection and Packaging: Through stringent and rigorous testing, we ensure that each piece of Performance Steel Spring Wire meets strict industry-standard specifications. We then implement robust, secure packaging protocols to maintain product integrity and safety during transportation and storage, ensuring our customers receive the highest quality products reliably and efficiently.
Spring steel wire is a precisely engineered steel wire designed for crafting various springs or model parts. Its extensive applications range from mattress springs to suspension systems, engine valves, and camera shutters. Quality standards vary across types, with options including raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each meticulously engineered to meet specific performance requirements and deliver optimal results.
