熱鍍(du)鋅生產(chan)發展一直(zhi)處(chu)于滯后狀態。20世紀(ji)50年(nian)代(dai)到(dao)60年(nian)代(dai)陸續建(jian)成(cheng)了13條單張(zhang)鋼板(ban)熔劑法熱鍍(du)鋅機(ji)組，能力為10萬t/a，但(dan)因(yin)產(chan)量低、成(cheng)本高、質量差(cha)、污染環境、經濟(ji)效益差(cha)等缺陷(xian)已先后停、轉產(chan)。從(cong)20世紀(ji)70年(nian)代(dai)末，我(wo)國才開始(shi)建(jian)造大型(xing)寬帶(dai)熱鍍(du)鋅機(ji)組。熱鍍(du)鋅帶(dai)鋼在我(wo)國市場一直(zhi)是緊缺品(pin)種(zhong)。從(cong)20世紀(ji)90年(nian)代(dai)中期以來，每(mei)年(nian)都要從(cong)國外進口80-100萬t左右。隨(sui)著國內(nei)經濟(ji)的(de)發展，尤(you)其(qi)是汽車、家(jia)電及建(jian)筑業的(de)發展，對鍍(du)鋅帶(dai)鋼的(de)需求量也大大增加(jia)。
