鍍(du)鋅(xin)(xin)(xin)(xin)帶(dai)鋼的(de)鋅(xin)(xin)(xin)(xin)層特性 電鍍(du)鋅(xin)(xin)(xin)(xin)層是(shi)不(bu)能形(xing)成鋅(xin)(xin)(xin)(xin)花(hua)(hua)的(de)，熱(re)鍍(du)鋅(xin)(xin)(xin)(xin)層則(ze)有(you)鋅(xin)(xin)(xin)(xin)花(hua)(hua)，其形(xing)成過程如下：當鍍(du)鋅(xin)(xin)(xin)(xin)帶(dai)從鋅(xin)(xin)(xin)(xin)鍋出來后，經氣刀(dao)的(de)噴(pen)吹，大量(liang)鋅(xin)(xin)(xin)(xin)液(ye)被吹回鋅(xin)(xin)(xin)(xin)鍋，這時帶(dai)鋼表(biao)面(mian)還有(you)純鋅(xin)(xin)(xin)(xin)層，呈液(ye) 態附在(zai)鋼板表(biao)面(mian)，在(zai)鋼板表(biao)面(mian)形(xing)成大量(liang)結晶(jing)核，隨著鋼板上升冷卻，使結晶(jing)核慢慢長成鋅(xin)(xin)(xin)(xin)花(hua)(hua)。冷卻速度越快(kuai)鋅(xin)(xin)(xin)(xin)花(hua)(hua)越小(xiao)，冷卻速度越慢鋅(xin)(xin)(xin)(xin)花(hua)(hua)越大。熱(re)鍍(du)鋅(xin)(xin)(xin)(xin)帶(dai)鋼在(zai)我國(guo)市場(chang)一(yi)直是(shi)緊缺品種。從20世紀90年代中期以來，每年都(dou)要從國(guo)外進口80-100萬t左右。隨著國(guo)內(nei)經濟(ji)的(de)發展，尤(you)其是(shi)汽車、家電及(ji)建(jian)筑業(ye)的(de)發展，對鍍(du)鋅(xin)(xin)(xin)(xin)帶(dai)鋼的(de)需求(qiu)量(liang)也大大增加。

鍍鋅帶鋼廠家鍍鋅鋼板是為防止鋼板表面遭受腐蝕，延長其使用壽命，在鋼板表面涂以一層金屬鋅，這種涂鋅的薄鋼板稱為鍍鋅板。彭水酒鋼鍍鋅帶鋼鋼(gang)(gang)(gang)板(ban)(ban)也(ye)是(shi)(shi)用(yong)熱(re)浸(jin)(jin)法(fa)制造(zao)，但在(zai)出槽后，立即把它(ta)加熱(re)到500℃左右(you)，使(shi)其(qi)(qi)生成(cheng)(cheng)(cheng)(cheng)鋅(xin)(xin)和(he)鐵的(de)(de)合金(jin)(jin)被(bei)膜。這(zhe)種鍍(du)鋅(xin)(xin)卷(juan)具有良好的(de)(de)涂料的(de)(de)密(mi)著性(xing)(xing)(xing)和(he)焊接性(xing)(xing)(xing)。合金(jin)(jin)化鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)。這(zhe)種鋼(gang)(gang)(gang)板(ban)(ban)也(ye)是(shi)(shi)用(yong)熱(re)浸(jin)(jin)法(fa)制造(zao)，但在(zai)出槽后，立即把它(ta)加熱(re)到500℃左右(you)，使(shi)其(qi)(qi)生成(cheng)(cheng)(cheng)(cheng)鋅(xin)(xin)和(he)鐵的(de)(de)合金(jin)(jin)被(bei)膜。這(zhe)種鍍(du)鋅(xin)(xin)板(ban)(ban)具有良好的(de)(de)涂料的(de)(de)密(mi)著性(xing)(xing)(xing)和(he)焊接性(xing)(xing)(xing)。熱(re)浸(jin)(jin)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)。將薄鋼(gang)(gang)(gang)板(ban)(ban)浸(jin)(jin)入熔(rong)解(jie)的(de)(de)鋅(xin)(xin)槽中，使(shi)其(qi)(qi)表(biao)面粘附一(yi)層鋅(xin)(xin)的(de)(de)薄鋼(gang)(gang)(gang)板(ban)(ban)。目前(qian)主要(yao)采用(yong)連續鍍(du)鋅(xin)(xin)工藝(yi)生產，即把成(cheng)(cheng)(cheng)(cheng)卷(juan)的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)連續浸(jin)(jin)在(zai)熔(rong)解(jie)有鋅(xin)(xin)的(de)(de)鍍(du)槽中制成(cheng)(cheng)(cheng)(cheng)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)。合金(jin)(jin)、復(fu)合鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)。它(ta)是(shi)(shi)用(yong)鋅(xin)(xin)和(he)其(qi)(qi)他金(jin)(jin)屬如鉛、鋅(xin)(xin)制成(cheng)(cheng)(cheng)(cheng)合金(jin)(jin)乃(nai)至復(fu)合鍍(du)成(cheng)(cheng)(cheng)(cheng)的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)。這(zhe)種鋼(gang)(gang)(gang)板(ban)(ban)既具有防銹性(xing)(xing)(xing)能，又有良好的(de)(de)涂裝性(xing)(xing)(xing)能。
