白鐵批發熱鍍鋅卷板現貨消息：熱鍍鋅產品廣泛用于建筑、家電、車船、容器制造業、機電業等，幾乎涉及到衣食住行各個領域。近年來，世界鍍鋅鋼板需求量不斷增加，產量增長也很快，在美、日等鋼材生產大國，熱鍍鋅鋼板在鋼材中所占比例已高達13%-15%。攀鋼白鐵批發 熱鍍鋅卷板(ban)現貨消息：近來，汽車(che)行業越(yue)來越(yue)重視材料的使用壽命，用涂漆冷軋鋼板(ban)已(yi)不能滿足耐腐蝕(shi)方面的要求。在這種情況下，耐腐蝕(shi)性(xing)優良且成本低(di)廉的熱鍍鋅板(ban)開始普遍受(shou)到了汽車(che)廠家的青睞(lai)。

熱鍍(du)鋅(xin)(xin)(xin)生產發(fa)展(zhan)一直處于滯后狀(zhuang)態。20世紀(ji)50年(nian)代到(dao)60年(nian)代陸續建成了13條單張(zhang)鋼(gang)板熔(rong)劑(ji)法(fa)熱鍍(du)鋅(xin)(xin)(xin)機(ji)組(zu)(zu)，能力為10萬t/a，但因產量(liang)(liang)低、成本高(gao)、質量(liang)(liang)差(cha)、污染環(huan)境(jing)、經濟(ji)(ji)效(xiao)益差(cha)等缺陷已(yi)先后停、轉(zhuan)產。從20世紀(ji)70年(nian)代末，我國才開始建造大(da)(da)型寬帶熱鍍(du)鋅(xin)(xin)(xin)機(ji)組(zu)(zu)。熱鍍(du)鋅(xin)(xin)(xin)帶鋼(gang)在我國市(shi)場一直是緊(jin)缺品種。從20世紀(ji)90年(nian)代中期以來，每年(nian)都(dou)要從國外進口80-100萬t左右。隨著(zhu)國內(nei)經濟(ji)(ji)的(de)發(fa)展(zhan)，尤其(qi)是汽(qi)車、家電及建筑業的(de)發(fa)展(zhan)，對鍍(du)鋅(xin)(xin)(xin)帶鋼(gang)的(de)需求量(liang)(liang)也大(da)(da)大(da)(da)增(zeng)加。

鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)是一(yi)種(zhong)(zhong)經(jing)常(chang)采用(yong)的(de)經(jing)濟而有效(xiao)的(de)防腐(fu)方法。鋅(xin)(xin)(xin)(xin)產量的(de)一(yi)半左右均用(yong)于此種(zhong)(zhong)工藝(yi)。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)是為防止鋼(gang)板(ban)表(biao)面(mian)遭(zao)受腐(fu)蝕延長(chang)其使用(yong)壽(shou)命，在鋼(gang)板(ban)表(biao)面(mian)涂以一(yi)層金屬鋅(xin)(xin)(xin)(xin)，這種(zhong)(zhong)涂鋅(xin)(xin)(xin)(xin)的(de)鋼(gang)板(ban)稱為鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)主要用(yong)于建(jian)(jian)筑、家電、汽車、容(rong)器、交通(tong)及家業等領域。特別(bie)是鋼(gang)結構建(jian)(jian)筑、汽車制造、鋼(gang)板(ban)倉制造等行(xing)業。耐腐(fu)蝕強(qiang)、表(biao)面(mian)質(zhi)量好(hao)、得利于深加工、經(jing)濟實用(yong)等。有關產品標準都列(lie)明鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)推薦的(de)標準厚度(du)、長(chang)度(du)和寬度(du)及其允許偏差。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)厚度(du)偏差一(yi)般在0.05mm，長(chang)寬偏差一(yi)般在5mm ，板(ban)材的(de)厚度(du)一(yi)般在0.2-3.2之間(jian) 。
