熱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。寧夏攀鋼熱鍍鋅鋼管冷(leng)卻速度(du)越快鋅花(hua)越小，冷(leng)卻速度(du)越慢鋅花(hua)越大。熱鍍(du)鋅帶鋼(gang)在(zai)我國市場(chang)一(yi)直是緊缺品種。從(cong)20世紀90年代中(zhong)期以來，每年都要(yao)從(cong)國外(wai)進(jin)口80-100萬t左右。隨著國內經濟的發展，尤其是汽(qi)車、家電及(ji)建(jian)筑業的發展，對鍍(du)鋅帶鋼(gang)的需(xu)求量也(ye)大大增加。
