冷軋板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。寶雞攀鋼冷軋板冷卻速(su)度(du)越(yue)快(kuai)鋅(xin)花越(yue)小(xiao)，冷卻速(su)度(du)越(yue)慢鋅(xin)花越(yue)大。熱(re)鍍鋅(xin)帶鋼在我國(guo)(guo)市場(chang)一(yi)直是(shi)緊缺品(pin)種。從20世(shi)紀90年代中期以來，每年都(dou)要從國(guo)(guo)外進口80-100萬t左右。隨著(zhu)國(guo)(guo)內經濟的發(fa)展，尤其是(shi)汽車(che)、家(jia)電及建筑業的發(fa)展，對鍍鋅(xin)帶鋼的需求(qiu)量(liang)也(ye)大大增加。
