熱(re)鍍鋅(xin)生產發展(zhan)一(yi)直(zhi)(zhi)處于滯后(hou)狀(zhuang)態。20世(shi)紀(ji)50年(nian)(nian)代(dai)(dai)到60年(nian)(nian)代(dai)(dai)陸續(xu)建成(cheng)了13條(tiao)單張(zhang)鋼(gang)板熔劑法熱(re)鍍鋅(xin)機(ji)組，能力為(wei)10萬t/a，但因產量(liang)低、成(cheng)本高、質(zhi)量(liang)差(cha)、污染環境、經濟效益差(cha)等缺(que)陷已先后(hou)停、轉(zhuan)產。從(cong)(cong)20世(shi)紀(ji)70年(nian)(nian)代(dai)(dai)末，我國(guo)才開始建造大(da)(da)型寬帶熱(re)鍍鋅(xin)機(ji)組。熱(re)鍍鋅(xin)帶鋼(gang)在我國(guo)市場(chang)一(yi)直(zhi)(zhi)是(shi)緊缺(que)品種。從(cong)(cong)20世(shi)紀(ji)90年(nian)(nian)代(dai)(dai)中期(qi)以來，每年(nian)(nian)都要從(cong)(cong)國(guo)外(wai)進口80-100萬t左右。隨著國(guo)內(nei)經濟的發展(zhan)，尤其是(shi)汽車、家電及建筑業的發展(zhan)，對(dui)鍍鋅(xin)帶鋼(gang)的需求(qiu)量(liang)也大(da)(da)大(da)(da)增加(jia)。

熱(re)鍍(du)鋅(xin)卷(juan)板(ban)(ban)現貨(huo)(huo)消息(xi)：熱(re)鍍(du)鋅(xin)產品廣泛用(yong)于(yu)建(jian)筑(zhu)、家(jia)電(dian)、車船(chuan)、容(rong)器制(zhi)造業、機電(dian)業等，幾乎涉(she)及到衣食住行各個(ge)領域。近(jin)年來(lai)，世界鍍(du)鋅(xin)鋼(gang)(gang)板(ban)(ban)需求(qiu)量不(bu)斷增加，產量增長也很快，在(zai)(zai)美、日等鋼(gang)(gang)材(cai)生(sheng)產大國，熱(re)鍍(du)鋅(xin)鋼(gang)(gang)板(ban)(ban)在(zai)(zai)鋼(gang)(gang)材(cai)中所占比例已高達(da)13%-15%。 熱(re)鍍(du)鋅(xin)卷(juan)板(ban)(ban)現貨(huo)(huo)消息(xi)：近(jin)來(lai)，汽車行業越來(lai)越重(zhong)視材(cai)料(liao)的使用(yong)壽(shou)命(ming)，用(yong)涂漆(qi)冷軋鋼(gang)(gang)板(ban)(ban)已不(bu)能滿足耐腐蝕方(fang)面的要求(qiu)。在(zai)(zai)這(zhe)種情況下(xia)，耐腐蝕性優良且成本(ben)低廉的熱(re)鍍(du)鋅(xin)板(ban)(ban)開始(shi)普遍受(shou)到了汽車廠家(jia)的青(qing)睞(lai)。

近(jin)期鋼價(jia)延續(xu)低(di)迷，隨著通國規模的酷暑和旱季到來，熱(re)鍍鋅(xin)卷板價(jia)格商(shang)(shang)場(chang)(chang)逐漸(jian)進入需要(yao)旺季，海(hai)內鋼鐵商(shang)(shang)場(chang)(chang)或將窄(zhai)幅調整。在(zai)決(jue)策(ce)層兩手抓制度(du)措(cuo)施落實狀況、貨銀本位度(du)定向(xiang)寬松(song)力度(du)加大的直觀(guan)層面(mian)利(li)好牽動下(xia)，商(shang)(shang)場(chang)(chang)信(xin)念逐漸(jian)趨(qu)穩，短(duan)期海(hai)內鋼價(jia)無望止跌企(qi)穩;另一(yi)上(shang)(shang)面(mian)，以后(hou)鋼價(jia)殺跌電能有(you)余，而上(shang)(shang)漲也仍(reng)然屏障重重。熱(re)鍍鋅(xin)卷板價(jia)格價(jia)錢或將長期在(zai)于低(di)位運行場(chang)(chang)面(mian)。
