鍍鋅鋼管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。昆山攀華鍍鋅鋼管冷卻(que)速度(du)越(yue)快鋅花(hua)越(yue)小(xiao)，冷卻(que)速度(du)越(yue)慢鋅花(hua)越(yue)大(da)。熱鍍鋅帶鋼(gang)在我國市(shi)場一直(zhi)是緊缺(que)品種(zhong)。從20世紀90年(nian)代(dai)中(zhong)期以來，每年(nian)都要從國外進口80-100萬t左右(you)。隨著國內經濟的(de)發展(zhan)，尤其(qi)是汽車(che)、家電及建筑業的(de)發展(zhan)，對鍍鋅帶鋼(gang)的(de)需求(qiu)量也大(da)大(da)增加(jia)。
