工艺


将炽热的金属坯轧成6.5mm粗的钢条也就是盘条,再将其放入拉丝装置内拉成不同直径的线,并逐步缩小拉丝盘的孔径,进行冷却、退火、涂镀等加工工艺制成各种不同规格的铁丝。它含有的成分有:铁,钴,镍,铜,碳,锌,还有其他元素。


特点

黑铁丝具有良好的弹性和柔韧性,可以在退火过程中控制它的软硬程度,由优质铁丝制成,主要用于建筑行业作捆绑丝及绑线。丝号主要有5#-38#(丝经0.17-4.5mm)

特质

比普通黑铁丝更软,柔韧性更强,柔软度均匀,色度一致。

用途

主要用于建筑、矿山、化工、焊网、焊衣架、再加工等。退火后铁丝变软,柔韧度增加,做建筑绑丝、绑扎钢筋效果更加。

目前,退火丝和钢丝的生产普遍采用拉丝工艺和镀锌处理。1976年,广州镀锌铁丝厂在国内首先应用电解酸洗、高压冲洗、卡电干燥的新技术试验成功了拉丝线连续生产,使拉丝工艺从间断性生产变为连续性生产,减弱了劳动强度,降低了金属消耗。那时,国内铁丝厂已能生产钢丝绳、辐条钢丝、伞骨钢丝、弹簧钢丝、自行车鞍座弹簧钢丝等产品。20世纪80年代,钉书用热镀低碳钢丝、风扇网罩钢丝、碳素结构钢丝、床面钢丝等也相继问世。

包装

黑铁丝的包装同镀锌丝的包装一样,分里塑外麻、里塑外编,及先用一层薄薄的塑料将丝缠绕一圈,再用麻包或者是编织袋将其缠绕!
