Production Process of Spring Steel Wire
Material Selection and Pretreatment: Our journey begins with the selection of premium high carbon or alloy steel, lauded for its superior elasticity and robustness. The meticulous preprocessing phase involves controlled heating and rolling, expertly tuning the microstructure to elevate mechanical attributes. This crucial groundwork lays the foundation for our wire's unmatched quality and dependable performance.
Step One
Surface Treatment: At this stage, we utilize exclusive techniques such as acid pickling phosphating or mechanical methods, each strategically chosen to effectively remove iron oxide scale, create a protective phosphating layer, or achieve an impeccably smooth surface. For spring steel wires with demanding fatigue life requirements, such as those used in valve springs, coil peeling becomes essential to reduce surface defects.
Step Two
Wire Drawing: This intricate procedure skillfully reduces the steel wire's diameter through successive cold drawing, significantly boosting its strength and hardness. Maintaining an outlet temperature below 150 ºC during each drawing pass is vital for high-strength spring steel wire to prevent strain aging and torsional cracks. Efficient lubrication and cooling systems are critical to managing rising temperatures.
Heat Treatment: This crucial stage encompasses quenching and tempering processes. Carbon steel spring wires commonly undergo lead bath quenching to achieve a refined pearlite structure. Alloy steel wires benefit from annealing heat treatments, while stainless steel wires are processed using solid solution methods. In the oil quenching process, water quenching or polymer-enhanced water quenching can be incorporated for optimal results.
Step Three
Forming: Using precise equipment, we skillfully wind the drawn steel wire into various spring configurations, including compression and tension springs, custom-crafted to fulfill a broad spectrum of application needs.
Inspection and Packaging: Through stringent testing, we verify that each spring steel wire conforms to rigorous standard specifications. We then employ secure packaging solutions to ensure product integrity and safety during both transportation and storage.
Spring steel wire is a masterfully engineered steel wire essential for manufacturing springs or model parts. Its extensive applications include mattress springs, suspension springs, engine valves, and camera shutters. Quality standards differ among types, such as raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each crafted to meet specific demands.
