江北熱鍍鋅鋼管重慶鍍鋅板近二十年來鋼帶連續熱鍍鋅技術、裝備以及相應的控制手段均有巨大的發展，使鍍鋅板得以滿足汽車面板和家電用板的苛刻要求，并從而以其比電鍍鋅合金鋼帶廉價、耐蝕性優異而大有取代之勢。攀鋼熱鍍鋅鋼管批發熱鍍鋅生產技術(shu)與裝備(bei)開發技術(shu)及經驗，通過技術(shu)創新、優化設計(ji)、精密制造以及國外(wai)技術(shu)合(he)作，突破制約我國高性(xing)能汽車用熱鍍鋅鋼板生產技術(shu)與裝備(bei)發展瓶頸。

彩(cai)(cai)(cai)鋼是(shi)指彩(cai)(cai)(cai)涂(tu)鋼板(ban)(ban)(ban)(ban)，彩(cai)(cai)(cai)涂(tu)鋼板(ban)(ban)(ban)(ban)是(shi)一種帶(dai)有有機涂(tu)層的(de)(de)(de)鋼板(ban)(ban)(ban)(ban)，傳統的(de)(de)(de)涂(tu)層分好幾類(lei)，氟碳涂(tu)層的(de)(de)(de)，幾乎可(ke)以(yi)防(fang)腐(fu)20年。一般從鋼廠(chang)以(yi)卷筒的(de)(de)(de)形式(shi)分銷到各地。我們經常看到的(de)(de)(de)彩(cai)(cai)(cai)鋼板(ban)(ban)(ban)(ban)是(shi)指加(jia)工好的(de)(de)(de)板(ban)(ban)(ban)(ban)材(cai)，厚(hou)度(du)在50~100mm左(zuo)右，它是(shi)由中間的(de)(de)(de)填(tian)料和兩面的(de)(de)(de)彩(cai)(cai)(cai)鋼板(ban)(ban)(ban)(ban)組成。其中，彩(cai)(cai)(cai)板(ban)(ban)(ban)(ban)厚(hou)度(du)有0.4mm、0.5mm、0.6mm等不同(tong)的(de)(de)(de)厚(hou)度(du),中間層可(ke)以(yi)是(shi)聚(ju)胺(an)脂、巖綿或泡沫塑(su)料等。由于有專用(yong)型材(cai)，所以(yi)用(yong)彩(cai)(cai)(cai)鋼板(ban)(ban)(ban)(ban)構筑的(de)(de)(de)廠(chang)房建造速度(du)很(hen)快（如非典時的(de)(de)(de)小湯山醫(yi)院），但強(qiang)度(du)低。

重慶鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)按生產及加工方法可(ke)分為(wei)以下幾類(lei)： 熱浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)。將(jiang)薄(bo)鋼板(ban)(ban)(ban)浸入熔解的鋅(xin)(xin)(xin)槽中，使(shi)其表面(mian)粘(zhan)附一層鋅(xin)(xin)(xin)的薄(bo)鋼板(ban)(ban)(ban)。目前主(zhu)要(yao)采(cai)用(yong)連續(xu)(xu)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)工藝生產，即(ji)(ji)把(ba)成(cheng)卷的鋼板(ban)(ban)(ban)連續(xu)(xu)浸在熔解有鋅(xin)(xin)(xin)的鍍(du)(du)(du)(du)槽中制成(cheng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)； 合(he)金化(hua)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)。為(wei)克服單(dan)面(mian)未(wei)涂(tu)鋅(xin)(xin)(xin)的缺點，又有一種(zhong)(zhong)在另面(mian)涂(tu)以薄(bo)層鋅(xin)(xin)(xin)的鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)，即(ji)(ji)雙面(mian)差鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)；合(he)金、復合(he)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)和(he)其他金屬(shu)如鉛、鋅(xin)(xin)(xin)制成(cheng)合(he)金乃至復合(he)鍍(du)(du)(du)(du)成(cheng)的鋼板(ban)(ban)(ban)。這種(zhong)(zhong)鋼板(ban)(ban)(ban)既(ji)具(ju)有防銹性能，又有良好的涂(tu)裝性能。

用(yong)(yong)(yong)(yong)電鍍(du)(du)(du)(du)法制造(zao)這(zhe)種(zhong)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)具(ju)(ju)有良(liang)好(hao)(hao)的(de)(de)(de)加工(gong)性(xing)。但鍍(du)(du)(du)(du)層(ceng)(ceng)較薄，耐腐蝕性(xing)不(bu)如(ru)熱浸(jin)法鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)；單(dan)面鍍(du)(du)(du)(du)和(he)(he)雙(shuang)面差(cha)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。單(dan)面鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)，即只在(zai)一面鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)產品。在(zai)焊接、涂(tu)(tu)裝、防(fang)銹(xiu)處理、加工(gong)等方面，具(ju)(ju)有比雙(shuang)面鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)好(hao)(hao)的(de)(de)(de)適應(ying)性(xing)。為克(ke)服單(dan)面未涂(tu)(tu)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)缺點(dian)，又有一種(zhong)在(zai)另面涂(tu)(tu)以薄層(ceng)(ceng)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)，即雙(shuang)面差(cha)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)；合金(jin)、復合鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。它是(shi)用(yong)(yong)(yong)(yong)鋅(xin)(xin)(xin)(xin)和(he)(he)其他(ta)金(jin)屬(shu)如(ru)鉛、鋅(xin)(xin)(xin)(xin)制成(cheng)合金(jin)乃至(zhi)復合鍍(du)(du)(du)(du)成(cheng)的(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)既(ji)具(ju)(ju)有防(fang)銹(xiu)性(xing)能，又有良(liang)好(hao)(hao)的(de)(de)(de)涂(tu)(tu)裝性(xing)能。 除(chu)上述五種(zhong)外，還(huan)有彩色鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)、印花(hua)涂(tu)(tu)裝鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)、聚氯(lv)乙(yi)烯(xi)疊(die)層(ceng)(ceng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)等。但目前常用(yong)(yong)(yong)(yong)的(de)(de)(de)仍為熱浸(jin)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)。 鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)按用(yong)(yong)(yong)(yong)途又可分(fen)為一般(ban)用(yong)(yong)(yong)(yong)、屋頂(ding)用(yong)(yong)(yong)(yong)、建筑外側板(ban)(ban)(ban)用(yong)(yong)(yong)(yong)、結構(gou)用(yong)(yong)(yong)(yong)、瓦壟板(ban)(ban)(ban)用(yong)(yong)(yong)(yong)、拉伸(shen)用(yong)(yong)(yong)(yong)和(he)(he)深(shen)沖用(yong)(yong)(yong)(yong)等鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。
