Production process of spring steel wire
Material Selection and Pretreatment: Our journey begins with the finest selection of high carbon steel or alloy steel, renowned for their exceptional elasticity and robust strength. During the preprocessing phase, these materials undergo precise heating and rolling procedures that significantly enhance their microstructure and mechanical properties, setting the stage for unmatched quality and performance.
Step One
Surface Treatment: This intricate phase involves advanced techniques, such as acid pickling phosphating or mechanical methods, meticulously chosen to remove iron oxide scales and create a protective phosphating film or achieve a flawless smooth surface. Particularly for spring steel wires that demand enhanced fatigue life, like valve spring steel wires, coil peeling is crucial in dramatically reducing surface imperfections.
Step Two
Wire Drawing: The wire drawing procedure expertly reduces the steel wire's diameter through sequential cold drawing, remarkably boosting its strength and hardness. For high-strength spring steel wire, controlling the outlet temperature below 150 ºC during each phase is essential to prevent strain aging and torsional fractures. Proper lubrication and cooling are vital in managing temperature elevations.
Heat Treatment: An essential phase involving quenching and tempering. Carbon steel spring wires generally undergo lead bath quenching to achieve a refined pearlite structure. In contrast, alloy steel wires benefit from annealing heat, while stainless steel wires are subjected to solid solution processes. The oil quenching technique might also use water quenching or water quenching with polymers for optimal results.
Step Three
Forming: Utilizing cutting-edge precision equipment, we expertly form the drawn steel wire into various spring shapes, including compression springs, tension springs, and more, addressing a wide range of application requirements with accuracy and efficiency.
Inspection and Packaging: Through comprehensive testing, we ensure that each spring steel wire meets rigorous standard specifications. Finally, secure packaging is employed to preserve the product's integrity and safety during both transit and storage.
Spring steel wire is a precision-crafted wire used in the creation of springs or model parts. Its applications are diverse, encompassing items such as mattress springs, subtractors, suspension springs, engine valves, and camera shutters. Quality specifications vary across different types, including raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each designed to fulfill specific requirements.
