鍍鋅卷價格鍍鋅帶鋼的鋅層特性 電鍍鋅層是不能形成鋅花的，熱鍍鋅層則有鋅花，其形成過程如下：當鍍鋅帶從鋅鍋出來后，經氣刀的噴吹，大量鋅液被吹回鋅鍋，這時帶鋼表面還有純鋅層，呈液 態附在鋼板表面，在鋼板表面形成大量結晶核，隨著鋼板上升冷卻，使結晶核慢慢長成鋅花。渝北酒鋼鍍鋅卷冷卻速(su)度越快鋅(xin)花越小，冷卻速(su)度越慢鋅(xin)花越大(da)。熱鍍鋅(xin)帶鋼(gang)(gang)在(zai)我國(guo)(guo)市場(chang)一(yi)直(zhi)是(shi)(shi)緊缺品種。從(cong)20世紀(ji)90年代中期以來，每年都(dou)要從(cong)國(guo)(guo)外進口80-100萬(wan)t左右(you)。隨著國(guo)(guo)內經濟的(de)發(fa)展(zhan)，尤其是(shi)(shi)汽車、家電及建筑業的(de)發(fa)展(zhan)，對鍍鋅(xin)帶鋼(gang)(gang)的(de)需(xu)求量也大(da)大(da)增加(jia)。
