高强度粗直径镀锌钢绞线的生产

Production of High Strength Large Diameter Galvanized Stranded Wire

以 1× 37- 2 2mm镀锌钢绞线为例介绍按ASTM 475标准生产的高强度级镀锌钢绞线的生产经验。利用高质量控冷盘条进行短流程定尺钢丝的生产 ,一方面 ,提高钢丝强度和韧性 ,降低能耗 ;另一方面 ,保证钢绞线的无接头生产。捻制时保证钢丝张力一致 ,可使成品在受到一个相当于最小破断拉力 10 %的拉力时 ,钢绞线直径无明显变化 ;同时 ,很好地控制工艺装配参数 ,可使钢绞线不松散 。

To introduce the production experiences of high strength large diameter galvanized stranded wire according to ASTM 475 taking 1×37 22?mm for example Producing the specified cut length wire with high quality cooling controlled high speed wire rods by short technological process can raise the wire strength,toughness and save power,and can assure the stranded wire without joint During stranding,in order to hardly make some change in the stranded wire diameter when it is under the load equal to 10% minimum breaking force,all wires tension must be assured equal The controlled assembling data can keep stranded wire no stresses
