Wire rod, preparation method and application of wire rod, clamping piece and preparation method of clamping piece
The invention discloses a wire rod, a preparation method and application thereof, a clamping piece and a preparation method of the clamping piece, and relates to the technical field of steel smelting. The element composition in the steel is controlled, the strengthening effect of manganese and chromium alloy elements is utilized, niobium, vanadium and titanium are combined for microalloying, and the weather-resistant effect of copper and nickel is utilized. The high-performance clamping piece is obtained through cold heading and cold extruding deformation production by ensuring fine grains and microalloy strengthening of tissues in steel and inhibiting precipitation of harmful tissues of bainite, meanwhile, the hardness of the prepared wire rod is moderate, the wire rod does not need to be subjected to acid pickling and phosphorization and can be directly subjected to cold drawing treatment, then steel wires obtained through drawing are subjected to spheroidizing annealing treatment, and the high-performance clamping piece is obtained through cold heading and cold extruding deformation production. And meanwhile, the product quality is ensured, and the cost is saved.
本发明公开了一种盘条及其制备方法和应用、夹片及其制备方法，涉及钢铁冶炼技术领域。通过控制钢中的元素组成，利用锰、铬合金元素的强化作用，铌、钒、钛联合微合金化，以及铜、镍的耐候作用。在保证钢中组织细晶和微合金强化的同时，抑制贝氏体有害组织的析出，同时制得的盘条硬度适中，盘条无需酸洗和磷化，可直接冷拉拔处理，再对拉拔获得的钢丝进行球化退火处理，然后经过冷镦冷挤压变形生产获得高性能夹片，提高后产品加工效率，同时保证产品质量，节约成本。
