由於海洋捕捞拉网用的镀锌钢丝绳在经受海水腐蚀条件下为提高其使用寿命而对钢丝表面锌层厚度的要求愈来愈迫切了。采用热镀锌先镀后拔工艺方法比传统的先拔后镀老工艺不尽提高了钢丝的内部机械性能,而且大大改善了镀锌层的结构,提高了锌层与
As the requirements of the galvanized steel wire rope for marine fishing nets to withstand the seawater corrosion conditions to improve the service life of the wire surface zinc layer thickness more and more urgent. Adopting hot dip galvanizing before plating and pulling process than the traditional first after the plating process to improve the internal mechanical properties of steel wire, and greatly improved the galvanized layer structure, improve the zinc layer and
