摘　　要：介绍8×K84WSNS+IWR-110 mm高强度高破断粗直径压实股钢丝绳研发过程。制绳钢丝生产选用特种钢号,确保钢丝的强度达到1 960 MPa。股绳生产采用多层压实,模拉与锻打相结合的方法,在满足绳径公差要求的同时,尽量提高钢丝绳的最小破断拉力。股绳下线压缩率为12%,上线压缩率为6%。生产过程中严格控制股径,提高对模具及锻打瓦的材质要求。合绳时选用合适的预变形器,控制好各股张力。结果显示,研制的钢丝绳实测绳径114.25 mm,拆股各项技术指标符合YB/T 5359—2010要求;整绳破断拉力达到9 000 k N时未出现断丝断股现象,完全达到客户要求。To introduce research process of 8 x K84WSNS ＋ IWR - 110 mm high strength high breaking large diameter com- pacted strand wire rope. Special steel grade is chosen in production of steel wire for rope, to guarantee steel wire strength reaches 1 960 MPa. The method of multi-layer compaction, combination of die drawing and forging is adopted in strand and rope production, meanwhile to meet requirement of rope diameter tolerance, increase minimum broken force of wire rope possibility. Strand rope underwire compression ratio is 12%, upper wire compression ratio is 6%. The strand diameter is controlled strictly in production process, increasing the material requirement of die and forging tile. Proper predeformation apparatus is chosen in wire laying, controlling each strand tension. Results show that actual rope diameter of wire rope re- searched is 114.25 mm, each technical indicators of dismantle strand meet requirements of YB/T 5359--2010. Wire rope breaking force reaches 9 000 kN, there is no broken wire and strand, fully reached requirements of customers.
