鍍鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)是為防止鋼(gang)(gang)(gang)板(ban)表(biao)面(mian)遭受腐蝕，延長其(qi)使(shi)用壽命，在鋼(gang)(gang)(gang)板(ban)表(biao)面(mian)涂以(yi)一層金(jin)(jin)屬鋅(xin)(xin)(xin)(xin)(xin)，這種(zhong)涂鋅(xin)(xin)(xin)(xin)(xin)的(de)薄(bo)(bo)鋼(gang)(gang)(gang)板(ban)稱(cheng)為鍍鋅(xin)(xin)(xin)(xin)(xin)板(ban)。鋼(gang)(gang)(gang)板(ban)也(ye)是用熱(re)浸(jin)(jin)法制造，但在出(chu)槽后，立(li)即(ji)把它加熱(re)到500℃左(zuo)(zuo)右，使(shi)其(qi)生成鋅(xin)(xin)(xin)(xin)(xin)和(he)鐵的(de)合(he)(he)金(jin)(jin)被膜(mo)。這種(zhong)鍍鋅(xin)(xin)(xin)(xin)(xin)卷具(ju)有(you)良好的(de)涂料(liao)的(de)密(mi)著性(xing)(xing)和(he)焊接(jie)性(xing)(xing)。合(he)(he)金(jin)(jin)化鍍鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)。這種(zhong)鋼(gang)(gang)(gang)板(ban)也(ye)是用熱(re)浸(jin)(jin)法制造，但在出(chu)槽后，立(li)即(ji)把它加熱(re)到500℃左(zuo)(zuo)右，使(shi)其(qi)生成鋅(xin)(xin)(xin)(xin)(xin)和(he)鐵的(de)合(he)(he)金(jin)(jin)被膜(mo)。這種(zhong)鍍鋅(xin)(xin)(xin)(xin)(xin)板(ban)具(ju)有(you)良好的(de)涂料(liao)的(de)密(mi)著性(xing)(xing)和(he)焊接(jie)性(xing)(xing)。熱(re)浸(jin)(jin)鍍鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)。將(jiang)薄(bo)(bo)鋼(gang)(gang)(gang)板(ban)浸(jin)(jin)入熔解的(de)鋅(xin)(xin)(xin)(xin)(xin)槽中，使(shi)其(qi)表(biao)面(mian)粘附(fu)一層鋅(xin)(xin)(xin)(xin)(xin)的(de)薄(bo)(bo)鋼(gang)(gang)(gang)板(ban)。目前主要采用連續鍍鋅(xin)(xin)(xin)(xin)(xin)工(gong)藝生產，即(ji)把成卷的(de)鋼(gang)(gang)(gang)板(ban)連續浸(jin)(jin)在熔解有(you)鋅(xin)(xin)(xin)(xin)(xin)的(de)鍍槽中制成鍍鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)。合(he)(he)金(jin)(jin)、復合(he)(he)鍍鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)。它是用鋅(xin)(xin)(xin)(xin)(xin)和(he)其(qi)他金(jin)(jin)屬如鉛、鋅(xin)(xin)(xin)(xin)(xin)制成合(he)(he)金(jin)(jin)乃至復合(he)(he)鍍成的(de)鋼(gang)(gang)(gang)板(ban)。這種(zhong)鋼(gang)(gang)(gang)板(ban)既具(ju)有(you)防銹性(xing)(xing)能(neng)，又有(you)良好的(de)涂裝(zhuang)性(xing)(xing)能(neng)。

C型鋼廠家熱鍍鋅生產發展一直處于滯后狀態。20世紀50年代到60年代陸續建成了13條單張鋼板熔劑法熱鍍鋅機組，能力為10萬t/a，但因產量低、成本高、質量差、污染環境、經濟效益差等缺陷已先后停、轉產。從20世紀70年代末，我國才開始建造大型寬帶熱鍍鋅機組。萬源C型鋼熱(re)鍍(du)鋅帶鋼在我(wo)國市場一(yi)直是緊缺(que)品種。從20世紀90年代中期(qi)以來，每年都要從國外(wai)進口80-100萬t左右(you)。隨著國內經濟的(de)發展，尤(you)其(qi)是汽車、家電及建(jian)筑業(ye)的(de)發展，對鍍(du)鋅帶鋼的(de)需求(qiu)量也大大增(zeng)加。

鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)是(shi)為(wei)防止鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面遭(zao)受腐蝕(shi)，延長其(qi)(qi)使(shi)(shi)用(yong)壽命，在鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面涂(tu)以一層(ceng)金屬鋅(xin)(xin)(xin)(xin)，這(zhe)種(zhong)涂(tu)鋅(xin)(xin)(xin)(xin)的薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)稱為(wei)鍍(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。按生產及加(jia)工方法可分為(wei)以下幾類：熱(re)(re)浸(jin)(jin)鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。將薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)(jin)入熔 微商貨源解的鋅(xin)(xin)(xin)(xin)槽(cao)中，使(shi)(shi)其(qi)(qi)表(biao)面粘附(fu)一層(ceng)鋅(xin)(xin)(xin)(xin)的薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。目前主要采用(yong)連續鍍(du)鋅(xin)(xin)(xin)(xin)工藝生產，即(ji)把成(cheng)卷的鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)連續浸(jin)(jin)在熔解有鋅(xin)(xin)(xin)(xin)的鍍(du)槽(cao)中制(zhi)(zhi)成(cheng)鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)；合金化鍍(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也是(shi)用(yong)熱(re)(re)浸(jin)(jin)法制(zhi)(zhi)造(zao)，但在出(chu)槽(cao)后，立即(ji)把它加(jia)熱(re)(re)到５００℃左右，使(shi)(shi)其(qi)(qi)生成(cheng)鋅(xin)(xin)(xin)(xin)和鐵(tie)的合金被膜(mo)。這(zhe)種(zhong)鍍(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)具有良(liang)好的涂(tu)料的密著性和焊(han)接性。
