摘　　要：密封钢丝绳具有高的破断拉力,良好的弹性模量、耐腐蚀性及抗旋转性能。为满足客户需求,研究开发了ZZZZ+WSC-133.0 mm高强度密封钢丝绳,结构采用四层全密封设计,充分考虑相邻层钢丝捻角匹配和同层钢丝间的合理间隙,相邻层钢丝捻角为16.5°~18.5°,同层钢丝间隙为0.1~0.3 mm。钢丝采用热镀锌铝合金生产工艺,内层绳圆钢丝公称抗拉强度级别为1960 MPa,Z形钢丝公称强度级别为1770 MPa。研制结果表明,制绳钢丝符合相关标准要求,实测钢丝绳直径135.7~136.0 mm,偏差为2.0%~2.3%,实测整绳破断拉力20709 kN,比客户要求的最小破断拉力20571kN高138 kN。Sealed wire rope has high breaking force,good elastic modulus,corrosion resistance and anti-rotation performance.To meet customer needs,researched and developed ZZZZ+WSC-133.0 mm high strength sealed wire ropes,Structure adopts four layer fully sealed design,fully considering matching of adjacent layers lay angles of steel wires and reasonable gap between same layer.Adjacent layers lay angle of steel wire is 16.5°~18.5°,and gap between same layer of steel wire is 0.1~0.3 mm.Steel wire is made of hot-dip galvanized aluminum alloy production process,nominal tensile strength grade of inner rope round steel wire is 1960 MPa,and nominal strength grade of Z-type steel wire is 1770 MPa.Development results indicate that rope making steel wire meets relevant standard requirements.Measured diameter of wire rope is 135.7~136.0 mm,deviation is 2.0%~2.3%,and measured breaking force of whole rope is 20709 kN.138 kN higher than the minimum breaking force of 20571 kN required by customers.
