一种高强度精细钢丝用盘条及其生产方法
摘要：
本发明一种高强度精细钢丝用盘条，其化学成分wt％为：C：0.84％～0.91％，Si：0.20％～0.35％，Mn：0.35％～0.60％，P≤0.012％，S≤0.010％，Al：0.0004％～0.0010％，Ti：0.0004％～0.0008％，全氧：0.0015％～0.0025％，其余为铁和不可避免的杂质。与现有技术相比，本发明的有益效果是：一种高强度精细钢丝用盘条及其生产方法，采用本发明提供的方案生产的盘条索氏体中渗碳体片层厚度控制在0.03μm-0.04μm，满足用户对强度在3500MPa级别的高强度精细钢丝的拉拔和合股断丝率不大于3次/吨的需求。
摘要（英）：

The invention relates to a wire rod for a high-strength fine steel wire. The wire rod comprises, by weight percentage, 0.84-0.91% of C, 0.20-0.35% of Si, 0.35-0.60% of Mn, not larger than 0.012% of P,not larger than 0.010% of S, 0.0004-0.0010% of Al, 0.0004-0.0008% of Ti, 0.0015-0.0025% of total oxygen and the balance iron and inevitable impurities. Compared with the prior art, the wire rod and the production method have the beneficial effects that the thickness of a cementite sheet layer in sorbite of the wire rod produced by adopting the scheme is controlled to be 0.03-0.04 micrometer, andthe user demand that the drawing and stranding breaking rate of the high-strength fine steel wire with strength of 3,500 MPa is not more than 3 times/ton is met.
