摘　　要：以直径6.25 mm,强度级别为1 570 MPa螺旋肋钢丝的生产为例,研究了张力状态下回火温度对成品钢丝力学性能影响。指出在370~380℃范围内,随着稳定化处理回火温度的升高,钢丝的规定非比例延伸应力和抗拉强度下降,塑性变化不大,对屈强比影响尤为明显。370℃下回火,钢丝的各项性能均良好,是最佳回火温度。Taking the production of 6.25 mm 1 570 MPa spiral ribbed steel wire as an example, the paperstudies the influence of tempering temperature under tension state on the mechanical properties of finishproduct of steel wire. within the range of 370-380 ℃ and with the increase of tempering temperature atstabilizing treatment, the stipulated non-proportional tensile stress and tensile strength of steel wire decreaseswith small change in plasticity and prominent influence on yield ratio. The best tempering temperature is 370℃ with good properties.
