Production Process of Spring Steel Wire
Material Selection and Pretreatment: At Tianjin Kaishuo Weiye Steel Co., Ltd., we commence our journey with the elite choice of high carbon or alloy steel, renowned for their remarkable elasticity and robust strength. In the preprocessing phase, we employ precise heating and rolling to meticulously refine the microstructure, thus elevating the mechanical properties. This essential step is the backbone that ensures our wire delivers unmatched quality and performance, setting new benchmarks in reliability and durability.
Step One
Surface Treatment: Our process involves employing cutting-edge techniques such as acid pickling phosphating or mechanical methods, carefully selected to eradicate iron oxide scale, establish a protective phosphating film, or achieve a flawlessly polished surface. For spring steel wires demanding extraordinary fatigue life, such as valve spring steel wires, coil peeling is a vital step to significantly reduce surface imperfections, ensuring longevity and superior performance.
Step Two
Wire Drawing: This sophisticated procedure artistically reduces the steel wire's diameter through a series of cold drawing stages, significantly amplifying its strength and hardness. For high-strength spring steel wire, maintaining the outlet temperature below 150 ºC during each drawing pass is imperative to prevent strain aging and torsional cracks. The process demands effective lubrication and cooling to expertly manage any temperature increase, ensuring the wire's structural integrity.
Heat Treatment: This crucial phase encompasses quenching and tempering techniques. Carbon steel spring wires typically undergo lead bath quenching to achieve a refined pearlite structure. Alloy steel wires gain their strength from specialized annealing heat treatments, while stainless steel wires are processed using advanced solid solution methods. The oil quenching process may include water quenching or polymer-enhanced water quenching to deliver superior results, enhancing the wire's resilience and durability.
Step Three
Forming: Utilizing precision equipment, we skillfully wind the drawn steel wire into various spring configurations, including compression springs and tension springs, customized to satisfy a wide range of application requirements. This precise forming process ensures that each spring is tailored to meet specific functional demands, offering optimal performance in any scenario.
Inspection and Packaging: Through comprehensive and meticulous testing, we ensure every spring steel wire adheres to stringent standard specifications. Following this rigorous inspection, we implement robust packaging solutions to maintain product integrity and safety during transportation and storage, ensuring that our products reach you in pristine condition.
Spring steel wire is an expertly crafted steel wire, designed with precision to create springs or model components. Its varied applications span from mattress springs to suspension springs, engine valves, and camera shutters. With diverse quality standards like raw drawn, lead quenched, galvanized, and oil quenched spring steel wire, each type is engineered to meet specific requirements, offering unparalleled versatility and efficiency in performance.
