成都鍍鋅帶鋼近期鋼價延續低迷，隨著通國規模的酷暑和旱季到來，熱鍍鋅卷板價格商場逐漸進入需要旺季，海內鋼鐵商場或將窄幅調整。在決策層兩手抓制度措施落實狀況、貨銀本位度定向寬松力度加大的直觀層面利好牽動下，商場信念逐漸趨穩，短期海內鋼價無望止跌企穩;另一上面，以后鋼價殺跌電能有余，而上漲也仍然屏障重重。鍍鋅帶鋼批發熱鍍(du)鋅卷(juan)板價格價錢或(huo)將(jiang)長期在于低位運(yun)行(xing)場面。

熱(re)浸(jin)(jin)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)將薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)浸(jin)(jin)入熔(rong)解的(de)鋅(xin)(xin)槽中，使其(qi)表(biao)面(mian)(mian)(mian)(mian)粘附一層鋅(xin)(xin)的(de)薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。目前主要(yao)采用(yong)連(lian)(lian)續鍍(du)鋅(xin)(xin)工(gong)藝生(sheng)產(chan)，即(ji)把成(cheng)卷的(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)連(lian)(lian)續浸(jin)(jin)在(zai)(zai)熔(rong)解有(you)鋅(xin)(xin)的(de)鍍(du)槽中制成(cheng)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban);合(he)(he)金化鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。這種鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)也是用(yong)熱(re)浸(jin)(jin)法制造(zao)，但在(zai)(zai)出槽后，立即(ji)把它加熱(re)到500 ℃左右(you)，使其(qi)生(sheng)成(cheng)鋅(xin)(xin)和鐵的(de)合(he)(he)金被膜。這種鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)具有(you)良(liang)(liang)好(hao)的(de)涂料的(de)密著性(xing)和焊(han)接性(xing);電(dian)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。用(yong)電(dian)鍍(du)法制造(zao)這種鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)具有(you)良(liang)(liang)好(hao)的(de)加工(gong)性(xing)。但鍍(du)層較薄，耐腐蝕性(xing)不(bu)如(ru)熱(re)浸(jin)(jin)法鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban);單(dan)面(mian)(mian)(mian)(mian)鍍(du)和雙面(mian)(mian)(mian)(mian)差鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。單(dan)面(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，即(ji)只在(zai)(zai)一面(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)的(de)產(chan)品(pin)。在(zai)(zai)焊(han)接、涂裝(zhuang)、防銹處理、加工(gong)等方面(mian)(mian)(mian)(mian)，具有(you)比雙面(mian)(mian)(mian)(mian)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)好(hao)的(de)適(shi)應性(xing)。

鍍(du)(du)(du)(du)鋅(xin)(xin)鋼板的表面鍍(du)(du)(du)(du)鋅(xin)(xin)主要采用的方法是(shi)熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)。熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)是(shi)由(you)較古老的熱(re)鍍(du)(du)(du)(du)方法發展(zhan)而來的，自從1836年法國把(ba)熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)應用于工業以來，已經有(you)一百七十(shi)年的歷(li)史了。然(ran)而，熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)工業是(shi)近(jin)三(san)十(shi)年來伴隨冷軋帶鋼的飛速發展(zhan)而得到(dao)了大(da)規(gui)模發展(zhan)。鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)液(ye)有(you)氰(qing)(qing)(qing)(qing)(qing)(qing)化(hua)物鍍(du)(du)(du)(du)液(ye)和無(wu)氰(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)兩類。氰(qing)(qing)(qing)(qing)(qing)(qing)化(hua)物鍍(du)(du)(du)(du)液(ye)中(zhong)(zhong)(zhong)分微氰(qing)(qing)(qing)(qing)(qing)(qing)、低氰(qing)(qing)(qing)(qing)(qing)(qing)、中(zhong)(zhong)(zhong)氰(qing)(qing)(qing)(qing)(qing)(qing)、和高(gao)氰(qing)(qing)(qing)(qing)(qing)(qing)幾類。無(wu)氰(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)有(you)堿性鋅(xin)(xin)酸鹽鍍(du)(du)(du)(du)液(ye)、銨鹽鍍(du)(du)(du)(du)液(ye)、硫酸鹽鍍(du)(du)(du)(du)液(ye)及無(wu)氨氯(lv)化(hua)物鍍(du)(du)(du)(du)液(ye)等。氰(qing)(qing)(qing)(qing)(qing)(qing)化(hua)鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)液(ye)均鍍(du)(du)(du)(du)能力好，得到(dao)的鍍(du)(du)(du)(du)層光滑(hua)細致，在生(sheng)產中(zhong)(zhong)(zhong)被長期采用。但由(you)于氰(qing)(qing)(qing)(qing)(qing)(qing)化(hua)物劇毒，對環境污染嚴重，近(jin)年來已趨向于采用低氰(qing)(qing)(qing)(qing)(qing)(qing)、微氰(qing)(qing)(qing)(qing)(qing)(qing)、無(wu)氰(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)液(ye)。

鍍(du)鋅是一(yi)(yi)(yi)種經(jing)常采用(yong)的(de)經(jing)濟(ji)而有效(xiao)的(de)防腐(fu)方(fang)法。鋅產(chan)量(liang)的(de)一(yi)(yi)(yi)半(ban)左右均用(yong)于此種工(gong)藝。鍍(du)鋅卷(juan)是為防止鋼(gang)板表(biao)(biao)面遭受腐(fu)蝕延(yan)長(chang)其使用(yong)壽命，在(zai)鋼(gang)板表(biao)(biao)面涂(tu)以一(yi)(yi)(yi)層金屬鋅，這種涂(tu)鋅的(de)鋼(gang)板稱為鍍(du)鋅卷(juan)。鍍(du)鋅卷(juan)主要用(yong)于建筑、家電、汽(qi)車、容器、交通及家業(ye)等(deng)領域。特(te)別是鋼(gang)結構建筑、汽(qi)車制造、鋼(gang)板倉制造等(deng)行業(ye)。耐腐(fu)蝕強、表(biao)(biao)面質量(liang)好、得利于深加工(gong)、經(jing)濟(ji)實用(yong)等(deng)。有關產(chan)品標準都列明(ming)鍍(du)鋅卷(juan)推薦的(de)標準厚度、長(chang)度和寬度及其允許偏差(cha)。鍍(du)鋅卷(juan)厚度偏差(cha)一(yi)(yi)(yi)般(ban)在(zai)0.05mm，長(chang)寬偏差(cha)一(yi)(yi)(yi)般(ban)在(zai)5mm ，板材的(de)厚度一(yi)(yi)(yi)般(ban)在(zai)0.2-3.2之間 。
