鋼(gang)絲繩是將力學性能和(he)幾(ji)何尺寸符合要求的(de)鋼(gang)絲按(an)照(zhao)一定的(de)規則捻制(zhi)在一起的(de)螺旋狀鋼(gang)絲束，被廣泛應(ying)用于冶(ye)金、船舶、電(dian)梯(ti)、索(suo)道、礦山、海洋、橋(qiao)梁、軍工、航天等(deng)各個(ge)行(xing)業和(he)領域(yu)，但你(ni)知道它是怎樣制(zhi)造出來的(de)嗎(ma)？

看完視(shi)頻(pin)后再(zai)來了解一些鋼絲繩的生產工藝流程

鋼絲繩的生產工藝(yi)流(liu)程

1鋼(gang)絲(si)繩的生(sheng)產工藝流程之拉絲(si)

原材料:這里說的(de)鋼絲繩拉絲是指原材料經過酸洗、磷化、剝(bo)殼、開坯，其間進行(xing)一(yi)次或多次的(de)拔拉，改變其分子機(ji)構(gou)，使其達到目標(biao)直(zhi)徑的(de)一(yi)種工藝(yi)手段。原材料有(you)0.14～10.00mm的(de)黑色(se)金(jin)屬和直(zhi)徑為0.01～16.00mm的(de)有(you)色(se)金(jin)屬。

酸洗：用酸液洗去鋼絲繩原材料表面(mian)銹蝕物和軋(ya)皮的過程(cheng)，在鋼絲繩生產工藝(yi)中又叫(jiao)剝(bo)殼(ke)，主(zhu)要把高線(xian)的氧化(hua)物剝(bo)離，以免(mian)鐵銹等雜質影響開坯，損壞拉絲模具。

磷化(hua)：通俗的說就是(shi)把材料浸入磷酸(suan)鹽(yan)溶(rong)液中，使其表(biao)面獲得一層不溶(rong)于水(shui)的磷酸(suan)鹽(yan)薄膜的工藝。在一定程度上防止腐蝕。

開坯：通(tong)過各種拉制金屬線的(de)模(mo)具中心(xin)的(de)一定形狀的(de)孔，圓(yuan)、方(fang)、八角或其它特(te)殊形狀。當金屬強行穿過模(mo)孔時(shi)尺寸、形狀都發生變化。

冷拔絲：普(pu)通(tong)的(de)(de)(de)圓鋼，讓它通(tong)過(guo)比它的(de)(de)(de)直徑小一點的(de)(de)(de)孔(kong)中強(qiang)行拉過(guo)，則圓鋼直徑就會(hui)(hui)變(bian)小，長(chang)度(du)會(hui)(hui)伸長(chang)，不(bu)斷重復這(zhe)樣的(de)(de)(de)加工過(guo)程，則圓鋼就會(hui)(hui)進(jin)一步(bu)變(bian)小。產生這(zhe)種(zhong)塑(su)(su)性(xing)(xing)變(bian)形以(yi)后的(de)(de)(de)鋼材硬度(du)會(hui)(hui)增加，塑(su)(su)性(xing)(xing)會(hui)(hui)基本消失。不(bu)要求(qiu)塑(su)(su)性(xing)(xing)，只要求(qiu)強(qiang)度(du)的(de)(de)(de)場合，可以(yi)使用這(zhe)樣的鋼材。

回火：因為(wei)鋼(gang)絲的(de)(de)分子結構已經(jing)破壞，只有回火再次還原鋼(gang)絲內部(bu)的(de)(de)結構。以便于再次拉(la)(la)絲，這(zhe)樣不易斷裂(lie)，而且能拉(la)(la)到(dao)我(wo)們想要的(de)(de)強(qiang)(qiang)度(du)(du)。強(qiang)(qiang)度(du)(du)就是(shi)(shi)(shi)我(wo)們說的(de)(de)的(de)(de)抗拉(la)(la)強(qiang)(qiang)度(du)(du)。強(qiang)(qiang)度(du)(du)是(shi)(shi)(shi)拉(la)(la)絲拉(la)(la)出來的(de)(de)，不是(shi)(shi)(shi)熱處理出來的(de)(de)。這(zhe)就是(shi)(shi)(shi)鋼(gang)絲繩工藝和機械加工工藝最大的(de)(de)區別了。一(yi)般的(de)(de)強(qiang)(qiang)度(du)(du)：1470N/mm2,1570N/mm2,1670N/mm2,1770N/mm2,1870N/mm2,1960N/mm2.強(qiang)(qiang)度(du)(du)越高，拉(la)(la)力(li)越強(qiang)(qiang)，但(dan)是(shi)(shi)(shi)韌性越差(cha)。所以，我(wo)們在鋼(gang)絲繩選型上應(ying)選擇合適的(de)(de)強(qiang)(qiang)度(du)(du)。不能一(yi)味高強(qiang)(qiang)度(du)(du)。高強(qiang)(qiang)度(du)(du)鋼(gang)絲繩拉(la)(la)力(li)是(shi)(shi)(shi)強(qiang)(qiang)的(de)(de)，但(dan)是(shi)(shi)(shi)在耐磨(mo)度(du)(du)和柔(rou)韌性方面比較弱。

2鋼絲繩的生產工(gong)藝流(liu)程之捻股

捻股的類型(xing)、結構(gou)和(he)用(yong)(yong)途 鋼絲(si)(si)(si)繩(sheng)(sheng)(sheng)的類型(xing)、結構(gou)、原(yuan)料和(he)生產工藝取決于用(yong)(yong)途。一般鋼絲(si)(si)(si)繩(sheng)(sheng)(sheng)用(yong)(yong)直徑(jing) 0.1～6.0mm 圓斷(duan)面的碳素鋼絲(si)(si)(si)。捻制(zhi)密封(feng)和(he)半密封(feng)鋼絲(si)(si)(si)繩(sheng)(sheng)(sheng)時，采用(yong)(yong) Z形和(he)其他異型(xing)鋼絲(si)(si)(si)。鋼絲(si)(si)(si)繩(sheng)(sheng)(sheng)的類型(xing)按用(yong)(yong)途分(fen)：有懸吊橋梁(liang)用(yong)(yong)繩(sheng)(sheng)(sheng)和(he)礦用(yong)(yong)捻股、架空(kong)索(suo)道用(yong)(yong)承載繩(sheng)(sheng)(sheng)、傳動裝(zhuang)置用(yong)(yong)牽引繩(sheng)(sheng)(sheng)、電(dian)梯用(yong)(yong)繩(sheng)(sheng)(sheng)、捆扎和(he)拖編(bian)貨物(wu)用(yong)(yong)系扎繩(sheng)(sheng)(sheng)等(deng)。鋼絲(si)(si)(si)繩(sheng)(sheng)(sheng)的品(pin)種不斷(duan)增多，結構(gou)日益復雜，除采用(yong)(yong)各種涂層(ceng)鋼絲(si)外，還使用不(bu)銹鋼(gang)絲(si)和(he)(he)(he)雙金(jin)屬(shu)鋼(gang)絲(si)。為(wei)確(que)保鋼(gang)絲(si)繩使用的(de)安全性(xing)和(he)(he)(he)可(ke)靠性(xing),要(yao)求鋼(gang)絲(si)繩有足夠的(de)強度(du)(du),良(liang)好(hao)的(de)撓性(xing)、捻制的(de)密實(shi)性(xing)、抗(kang)壓性(xing)、耐磨性(xing)、耐腐蝕(shi)性(xing)和(he)(he)(he)抗(kang)疲(pi)勞強度(du)(du)等，其中(zhong)強度(du)(du)最為(wei)重要(yao)。

鋼絲(si)繩的(de)(de)(de)截面(mian)結構有點接(jie)觸(chu)圓(yuan)(yuan)股(gu)(gu)、線(xian)接(jie)觸(chu)圓(yuan)(yuan)股(gu)(gu)、面(mian)接(jie)觸(chu)圓(yuan)(yuan)股(gu)(gu)、異型股(gu)(gu)、單(dan)層股(gu)(gu)不(bu)旋轉(zhuan)、密(mi)封(feng)及扁平等。其(qi)中面(mian)接(jie)觸(chu)圓(yuan)(yuan)股(gu)(gu)鋼絲(si)繩是靠捻股(gu)(gu)機的(de)(de)(de)牽(qian)引(yin)力將線(xian)接(jie)觸(chu)繩股(gu)(gu)通(tong)過(guo)拔絲(si)模(mo)或輥模(mo)拔制而成。通(tong)過(guo)拉模(mo)，繩股(gu)(gu)變形前和變形后的(de)(de)(de)截面(mian)

捻(nian)股中 有涂(tu)油和鍍層兩種防腐措施。

涂油

所有(you)鋼(gang)(gang)絲繩(sheng)(sheng)都必須(xu)涂(tu)油(you)。纖維(wei)(wei)芯(xin)浸(jin)油(you)，要求(qiu)(qiu)油(you)脂能(neng)夠保護纖維(wei)(wei)芯(xin)不(bu)(bu)腐爛、不(bu)(bu)銹蝕鋼(gang)(gang)絲,滋潤(run)纖維(wei)(wei),并(bing)(bing)從內部潤(run)滑鋼(gang)(gang)絲繩(sheng)(sheng)。表面(mian)涂(tu)油(you)使繩(sheng)(sheng)股中(zhong)所有(you)鋼(gang)(gang)絲表面(mian)都均(jun)勻地涂(tu)上一層(ceng)防銹潤(run)滑油(you)脂，其中(zhong)對摩擦提升和礦水大的(de)(de)礦井(jing)用(yong)繩(sheng)(sheng)，要涂(tu)增磨和抗水性強(qiang)的(de)(de)黑油(you)油(you)脂；其他用(yong)途則涂(tu)成膜性強(qiang)、防銹性能(neng)好的(de)(de)紅油(you)油(you)脂，并(bing)(bing)要求(qiu)(qiu)油(you)層(ceng)薄(bo)，便(bian)于(yu)在操作過程中(zhong)保持清潔。

鍍層

有鍍鋅、鍍鋁、涂尼龍或(huo)塑料等。鍍鋅又分鋼絲先鍍后(hou)(hou)拔(ba)的(de)(de)薄(bo)鍍層和鋼絲拔(ba)后(hou)(hou)鍍鋅的(de)(de)厚(hou)鍍層，厚(hou)鍍層的(de)(de)機械(xie)性能比光(guang)面鋼絲繩有所降低，宜在嚴重腐蝕環境(jing)中(zhong)使用。鍍鋁鋼絲繩比鍍鋅鋼絲繩更耐(nai)(nai)腐蝕、耐(nai)(nai)磨(mo)、耐(nai)(nai)熱，主要用于(yu)(yu)漁業拖(tuo)網船舶及含H2S的礦井等，采(cai)用先鍍后(hou)拔(ba)法生產。涂尼(ni)龍或(huo)塑料的鋼絲(si)繩分(fen)涂繩和涂股后(hou)合繩兩種。前(qian)者用于(yu)(yu)靜索，后(hou)者用于(yu)(yu)動索。
