The Art of Crafting Spring Steel Wire
Material Selection and Pretreatment: We begin our journey by selecting the finest high carbon steel or alloy steel, celebrated for their unmatched elasticity and formidable strength. Our preprocessing stage involves a careful symphony of heating and rolling, aimed at meticulously enhancing the microstructure and mechanical attributes, ensuring a foundation of unparalleled quality.
Step One
Surface Treatment: In the surface treatment stage, we employ precise techniques such as acid pickling phosphating or innovative mechanical methods. These are expertly selected to effectively remove iron oxide scale, forge a protective phosphating film, or craft a flawlessly smooth surface. For spring steel wires demanding supreme fatigue life, especially those used as valve spring steel wires, peeling the coil is an essential step to minimize surface imperfections.
Step Two
Wire Drawing: The wire drawing process skillfully reduces the diameter of the steel wire through a series of calculated cold drawing steps, significantly boosting its strength and hardness. In the case of high-strength spring steel wire, maintaining an outlet temperature below 150 ºC during each drawing pass is crucial to avert strain aging and torsional cracks. Effective lubrication and cooling techniques are vital to manage temperature increases.
Heat Treatment: This pivotal stage involves processes like quenching and tempering. Typically, carbon steel spring wires undergo lead bath quenching to achieve a refined pearlite structure. Meanwhile, alloy steel wires experience the benefits of annealing heat, and stainless steel wires are treated with solid solution processes. The oil quenching process may also integrate water quenching or water quenching with polymers to optimize outcomes.
Step Three
Forming: Utilizing precision equipment, we adeptly wind the drawn steel wire into an array of spring shapes, including compression springs, tension springs, and more, effectively meeting the diverse application needs of our clientele.
Inspection and Packaging: Our rigorous testing regimen ensures that each spring steel wire adheres to stringent standard requirements. Following this, we employ safe and secure packaging to guarantee the integrity and safety of the product during transportation and storage, safeguarding its pristine condition.
Spring steel wire is a meticulously crafted steel wire, essential for manufacturing springs or model parts. With its versatility, it finds applications in mattress springs, suspension springs, engine valves, and even camera shutters. The quality requirements vary among different types, including raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each precision-engineered to meet specific functional demands.
