彩涂卷廠家熱鍍鋅生產發展一直處于滯后狀態。20世紀50年代到60年代陸續建成了13條單張鋼板熔劑法熱鍍鋅機組，能力為10萬t/a，但因產量低、成本高、質量差、污染環境、經濟效益差等缺陷已先后停、轉產。從20世紀70年代末，我國才開始建造大型寬帶熱鍍鋅機組。陜西彩涂卷熱鍍鋅(xin)帶鋼(gang)(gang)在我國(guo)市場一(yi)直是緊缺品(pin)種。從20世紀90年代中(zhong)期以(yi)來，每年都要(yao)從國(guo)外進口80-100萬t左右。隨著國(guo)內經濟的發(fa)展(zhan)，尤其是汽車、家電及建筑業的發(fa)展(zhan)，對鍍鋅(xin)帶鋼(gang)(gang)的需(xu)求量也大(da)大(da)增加(jia)。
