6×36SW+IWR卸船机用钢丝绳的研制

介绍6×36SW+IWR-42.5 mm卸船机用钢丝绳的研制过程,包括制绳钢丝用原料的选择,钢丝热处理和拉拔工艺参数、钢丝绳结构和钢丝绳捻制工艺参数的确定。结果表明,总压缩率为80%~85%,平均部分压缩率为15%~20%,可得到制绳用钢丝良好的力学性能。采用股淋油润滑新工艺能有效提高钢丝绳耐疲劳性能,并显著提高股间钢丝的润滑效果,生产的卸船机用42.5 mm钢丝绳平均装卸量达到58万t。

Development of 6×36SW+IWR Wire Rope for Seaport Machine

To introduce the development of 6×36SW+IWR steel wire rope for seaport machine,including the selection of wire rod,heat treatment technology,wire drawing technology parameter,rope structure and twisting technology parameters.The result indicates that 80%~85% total draught and 15%～20% average partial draught are moderate to make good mechanical property of wires.New process pouring oil into strands can improve anti-fatigue property of rope and lubrication efficiency between wires in the strand.The average loading and unloading quantity of the developed rope with 42.5mm diameter for seaport machine is up to 580kt.
