Production process of spring steel wire
Material Selection and Pretreatment: We commence with the finest selection of high carbon steel or alloy steel, renowned for their extraordinary elasticity and robust strength. The preprocessing phase is a meticulous journey, involving precise heating and rolling that significantly enhance the microstructure and mechanical properties. This process lays the foundation for delivering unparalleled quality that surpasses industry expectations.
Step One
Surface Treatment: In this meticulous phase, we engage cutting-edge techniques such as acid pickling phosphating or employ advanced mechanical strategies. These are scrupulously chosen to completely remove iron oxide scale, form a protective phosphating layer, or achieve an impeccably smooth finish. Particularly for spring steel wires that require extended fatigue life, such as valve spring steel wires, coil peeling is crucial to substantially reduce surface imperfections.
Step Two
Wire Drawing: The wire drawing process is an art that expertly reduces the steel wire's diameter through successive cold drawing, markedly enhancing its strength and hardness. For high-strength spring steel wire, maintaining the outlet temperature below 150 ºC during each drawing stage is vital to prevent strain aging and torsional fractures. Effective lubrication and cooling are essential to control temperature increases, ensuring product integrity.
Heat Treatment: This essential phase includes precise quenching and tempering processes. Carbon steel spring wires typically undergo lead bath quenching to achieve a refined pearlite structure, while alloy steel wires benefit from specialized annealing heat treatments. Stainless steel wires are treated through solid solution methods. The oil quenching technique may also involve water quenching or water quenching with polymers to achieve the highest quality results.
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, among others. This caters to a wide array of application demands, ensuring versatility and adaptability in engineering solutions.
Inspection and Packaging: Through rigorous and thorough testing, we ensure each spring steel wire meets and exceeds stringent standard specifications. The final step involves implementing secure and safe packaging to ensure the product's integrity and safety during both transit and storage, maintaining its premium quality.
Spring steel wire is a precision-engineered product utilized in crafting springs or model components. It serves diverse purposes, including in mattress springs, subtractors, suspension springs, engine valves, and camera shutters. Quality requirements vary significantly across types, such as raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each meticulously tailored to meet specific industry needs and standards.
