鍍鋅鋼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。江津攀鋼鍍鋅鋼冷卻速(su)度越(yue)快鋅(xin)(xin)花越(yue)小(xiao)，冷卻速(su)度越(yue)慢鋅(xin)(xin)花越(yue)大。熱鍍(du)鋅(xin)(xin)帶鋼(gang)在我國(guo)市場一直是緊缺(que)品種。從(cong)20世(shi)紀(ji)90年代(dai)中(zhong)期以來，每(mei)年都(dou)要從(cong)國(guo)外(wai)進口80-100萬t左右。隨著國(guo)內經濟的發(fa)展，尤其(qi)是汽車(che)、家電(dian)及建筑業(ye)的發(fa)展，對(dui)鍍(du)鋅(xin)(xin)帶鋼(gang)的需求量也大大增加。
