Production process of spring steel wire
Material Selection and Pretreatment: We start with the crème de la crème of high carbon steel or alloy steel, celebrated for their remarkable elasticity and formidable strength. The preprocessing phase meticulously involves heating and rolling, which profoundly refine the microstructure and mechanical properties, laying the groundwork for unparalleled quality.
Step One
Surface Treatment: In this meticulous phase, we employ sophisticated techniques like acid pickling phosphating or mechanical strategies. These are expertly selected to eradicate iron oxide scale, establish a protective phosphating film, or attain an immaculate smooth surface. Especially for spring steel wires requiring an elevated fatigue life, such as valve spring steel wires, peeling the coil is pivotal to significantly diminish surface defects.
Step Two
Wire Drawing: The wire drawing process skillfully diminishes the steel wire's diameter through successive cold drawing, substantially elevating its strength and hardness. For high-strength spring steel wire, it's crucial to keep the outlet temperature below 150 ºC during each drawing phase to avert strain aging and torsional fractures. Effective lubrication and cooling play a vital role in regulating temperature increments.
Heat Treatment: This indispensable phase encompasses quenching and tempering. Carbon steel spring wires typically experience lead bath quenching to attain a refined pearlite structure. Conversely, alloy steel wires reap the benefits of annealing heat, while stainless steel wires are treated with solid solution processes. The oil quenching method may also incorporate water quenching or water quenching with polymers to achieve superior results.
Step Three
Forming: With state-of-the-art precision equipment, we expertly wind the drawn steel wire into an array of spring configurations, including compression springs, tension springs, and beyond, catering to a spectrum of application necessities.
Inspection and Packaging: Through rigorous testing, we ensure each spring steel wire conforms to stringent standard specifications. Finally, safe and secure packaging is implemented to maintain product integrity and safety throughout transit and storage.
Spring steel wire is a precision-engineered wire used in crafting springs or model parts. It finds diverse use in items such as mattress springs, subtractors, suspension springs, engine valves, and camera shutters. Quality requirements vary significantly across types, including raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each tailored to meet distinct needs.
