摘要
压实股钢丝绳具有破断拉力高、使用寿命长、耐磨性能好和抗变形等特点,可代替线接触钢丝绳产品。根据用户要求,采用钢丝绳设计软件设计工艺参数,并选用优质制绳钢丝组织生产。用辊轧法生产的32NAT15×K7、强度1 770 MPa压实股钢丝绳,实测直径平均值为33.26 mm,钢丝绳拆股后1.85 mm钢丝最低抗拉强度达1 820MPa,最低扭转值25次,最低弯曲值10次,钢丝破断拉力总和1 056.3 k N,合绳后拆股试验各项技术指标均达到YB/T 5359—2010规定,满足用户要求。
Compacted stand steel wire rope has the characteristics of high broken force,long service time,good wear resistance and deform resistance,and can substitute linear contact steel wire rope. According to the requirements of client,steel wire rope design software is adopted to design process parameter,and choose high quality wire to produce. The strength of developed 32NAT15 × K7 steel wire rope is 1 770 MPa,the measured average diameter of compacted strand steel wire rope produced by adopting rolling method is 33. 26 mm,after dismantle strand of the rope,the lowest tensile strength of diameter1. 85 mm wire can reach 1 820 MPa,lowest twist value is 25 times,lowest bending number is 10 times,total broken force of the rope is 1 056. 3 k N,technical indexs of dismantle strand test can reach the YB / T 5359—2010 regulation after closing,and meet the requirement of client.
