摘要
为生产出直径为0.50~0.80 mm细规格高强度制绳用碳素钢丝,以80#钢∮5.5mm盘条为原料,利用公司现有设备,进行工艺流程和工艺参数设计。经检测,钢丝强度达到2 400~2 800 MPa,高于YB/T5343—2015《制绳用钢丝》中钢丝1 960 MPa强度级的范围,且钢丝韧性指标扭转值和弯曲值未降低,使细规格钢丝的强度与韧性指标均维持在较高水平,满足了生产高强度高疲劳性能钢丝绳对钢丝的性能要求。
In order to produce 0.50-0.80 mm small sized high strength carbon steel wire for wire ropeapplication, the company, taking Ф 5.5 mm wire rod of 80 grade steel as raw material, utilized existingequipment and designed its process flow and process parameters. Inspection showed the wire strength reached2 400-2 800 MPa, higher than 1 960 MPa, the wire strength required by YB/T5343-2015 Steel Wire forWire Rope and the torsion and bending values for the index of wire toughness were not reduced. The indicesof the strength and toughness of small sized steel wire made for high strength and high fatigue wire ropemaintained at a satisfying level, meeting the requirement of wire properties at subsequent process.
