为满足海洋船舶用户对高强度、粗直径镀锌钢丝绳的要求,以宝钢77A热轧盘条为原料,拉丝采用直进式拉丝机,使用热镀锌工艺,捻制时严格控制预、后变形器的三辊间距及压弯量,采用定径装置控制钢丝绳直径,生产直径120 mm多丝复合结构8×84WSNS+IWR镀锌钢丝绳,给出股、芯的规格及钢丝直径等技术参数。所生产的钢丝绳的最小破断拉力达到8 570 kN。使用表明,该钢丝绳满足客户要求。
In order to meet the requirements of ocean vessel users for high strength and coarse diameter galvanized steel wire rope, Baosteel 77A hot rolled wire rod is used as raw material, drawing straight wire drawing machine, hot dip galvanizing process, pre-and post deformation The three-roll spacing and bending amount of the device are controlled by the sizing device. The diameter of the wire rope is controlled by a sizing device to produce the 8 × 84WSNS + IWR galvanized steel wire rope with a diameter of 120 mm and the technical specifications of the strands, cores and wire diameters. The minimum breaking force of the produced wire rope reached 8 570 kN. Use shows that the wire rope to meet customer requirements.
