白鐵批發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。廣西攀鋼白鐵冷(leng)卻速度越(yue)(yue)快鋅(xin)(xin)(xin)花越(yue)(yue)小，冷(leng)卻速度越(yue)(yue)慢(man)鋅(xin)(xin)(xin)花越(yue)(yue)大(da)。熱鍍鋅(xin)(xin)(xin)帶鋼(gang)(gang)在我(wo)國市場一直(zhi)是緊缺品種(zhong)。從20世紀(ji)90年(nian)代(dai)中期以(yi)來(lai)，每年(nian)都要從國外進口80-100萬t左右。隨著(zhu)國內經濟(ji)的(de)發展(zhan)，尤其是汽車(che)、家電及建筑業(ye)的(de)發展(zhan)，對鍍鋅(xin)(xin)(xin)帶鋼(gang)(gang)的(de)需(xu)求(qiu)量(liang)也(ye)大(da)大(da)增加。
