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 wire ropes with high breaking force, long life, good wear resistance and anti-deformation, etc., can replace the wire contact wire rope products. According to user requirements, using steel wire rope design software design process parameters, and use high-quality rope wire production. The 32NAT15 × K7 and 1 770 MPa compacted wire ropes were produced by the rolling method. The average measured diameter was 33.26 mm. The minimum tensile strength of the wire of 1.85 mm after wire rope demolition reached 1 820 MPa and the minimum twisting value was 25 times, the lowest The bending value is 10 times and the total breaking force of the steel wire is 1 056.3 kN. The technical indexes of the split-strand test after the composite rope meet the requirements of YB / T 5359-2010 to meet the requirements of users.
