热镀锌钢绞线镀锌钢丝介绍英文


Galvanized steel wire (galvanized steel wire)

Galvanized steel wire (galvanized steel wire) is 45 #, 65 #, 70 #, such as high-quality carbon structural steel drawing, and then by the galvanized (Electro-galvanized or hot-dip galvanizing) formed.

Physical Properties: galvanized steel wire surface smooth, bright and clean, there is no crack, the festival, from the thorn injuries and rust, zinc coating uniformity, strong adhesion, corrosion resistance and lasting strength, excellent toughness and elasticity. Tensile strength should be between 900Mpa-2200Mpa (wire diameter Φ0.2mm-Φ4.4mm). To reverse the number (Φ0.5mm) in more than 20 times, repeatedly bending in more than 13 times.

Uses: mainly used for cultivation in greenhouses, farms, cotton packing, springs and wire rope manufacturing.


镀锌钢丝

镀锌钢丝

镀锌钢丝是把45#、65#、70#等优质碳素结构钢拉拔,然后再经镀锌(电镀锌或热镀锌)而成。

镀锌钢丝是用热镀或电镀方法在表面镀锌的碳素钢丝。其性能与矫直回火钢丝相同。可用作无粘结预应力筋,但每平方米面积至少要镀200~300g锌。常用作斜拉桥的平行钢丝拉索(另外还采用柔性索套等作为外层防护)

物理性能:

镀锌钢丝表面平滑、光洁、没有裂纹地、节、起刺、伤痕和锈蚀,镀锌层均匀、附着力强、耐腐蚀力持久,韧性和弹性极好。抗拉强度应在900Mpa-2200Mpa之间(丝径Φ0.2mm-Φ4.4mm)。扭转次数(Φ0.5mm)在20次以上,反复弯曲应在13次以上。

热镀的锌层厚度为250g/m。大大提高了钢丝的抗腐蚀能力

用途:

镀锌钢丝主要用于种植大棚,养殖场,棉花打包,弹簧及钢丝绳的制造。适用于斜拉桥的钢索及污水池等环境条件恶劣的工程结构

拉拔工艺:

先镀后拔工艺:为提高镀锌钢丝性能,采用钢丝经铅悴火、镀锌后再拉拔至成品的工艺称先镀后拔工艺。典型工艺流程为:钢丝—铅淬火—镀锌—拉拔—成品钢丝。先镀后拔工艺是镀锌钢丝拉拔方法中流程最短的一种,可用于热镀锌或电镀锌后拉拔。热镀锌后拉拔较先拔后镀钢丝力学性能好,电镀锌后拉拔使锌层致密耐。两者均可得到薄而均匀的锌层,降低锌耗、减轻镀锌作业线负荷。
