冷軋板廠家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。上海攀華冷軋板冷卻速度(du)越快(kuai)鋅花越小(xiao)，冷卻速度(du)越慢鋅花越大(da)。熱鍍鋅帶(dai)鋼(gang)在(zai)我國(guo)市(shi)場一(yi)直(zhi)是緊缺品(pin)種。從20世紀90年代中期以來(lai)，每(mei)年都要從國(guo)外進口80-100萬t左右。隨著國(guo)內經(jing)濟(ji)的發(fa)展，尤其是汽車、家電及建(jian)筑業的發(fa)展，對鍍鋅帶(dai)鋼(gang)的需(xu)求量(liang)也大(da)大(da)增加。
