鍍(du)(du)鋅(xin)(xin)鋼(gang)板的(de)表面鍍(du)(du)鋅(xin)(xin)主要(yao)采用的(de)方法(fa)是熱(re)鍍(du)(du)鋅(xin)(xin)。熱(re)鍍(du)(du)鋅(xin)(xin)是由較古老的(de)熱(re)鍍(du)(du)方法(fa)發(fa)展而來(lai)的(de)，自從1836年(nian)法(fa)國把熱(re)鍍(du)(du)鋅(xin)(xin)應(ying)用于(yu)工業以(yi)來(lai)，已(yi)經有(you)一(yi)百七(qi)十(shi)年(nian)的(de)歷史(shi)了(le)。然而，熱(re)鍍(du)(du)鋅(xin)(xin)工業是近三(san)十(shi)年(nian)來(lai)伴隨冷軋帶鋼(gang)的(de)飛速發(fa)展而得(de)到了(le)大規模發(fa)展。鍍(du)(du)鋅(xin)(xin)溶液(ye)(ye)(ye)有(you)氰(qing)(qing)(qing)化物(wu)(wu)鍍(du)(du)液(ye)(ye)(ye)和無(wu)(wu)氰(qing)(qing)(qing)鍍(du)(du)液(ye)(ye)(ye)兩類。氰(qing)(qing)(qing)化物(wu)(wu)鍍(du)(du)液(ye)(ye)(ye)中分微(wei)氰(qing)(qing)(qing)、低(di)氰(qing)(qing)(qing)、中氰(qing)(qing)(qing)、和高氰(qing)(qing)(qing)幾類。無(wu)(wu)氰(qing)(qing)(qing)鍍(du)(du)液(ye)(ye)(ye)有(you)堿(jian)性鋅(xin)(xin)酸(suan)(suan)鹽(yan)鍍(du)(du)液(ye)(ye)(ye)、銨(an)鹽(yan)鍍(du)(du)液(ye)(ye)(ye)、硫酸(suan)(suan)鹽(yan)鍍(du)(du)液(ye)(ye)(ye)及(ji)無(wu)(wu)氨氯化物(wu)(wu)鍍(du)(du)液(ye)(ye)(ye)等。氰(qing)(qing)(qing)化鍍(du)(du)鋅(xin)(xin)溶液(ye)(ye)(ye)均(jun)鍍(du)(du)能力好，得(de)到的(de)鍍(du)(du)層光滑細致，在生產中被長期(qi)采用。但由于(yu)氰(qing)(qing)(qing)化物(wu)(wu)劇(ju)毒，對(dui)環境污(wu)染嚴重(zhong)，近年(nian)來(lai)已(yi)趨向于(yu)采用低(di)氰(qing)(qing)(qing)、微(wei)氰(qing)(qing)(qing)、無(wu)(wu)氰(qing)(qing)(qing)鍍(du)(du)鋅(xin)(xin)溶液(ye)(ye)(ye)。

鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)方管是(shi)一(yi)(yi)種具以(yi)熱(re)軋或(huo)(huo)冷(leng)軋鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)帶鋼(gang)或(huo)(huo)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)卷板為(wei)坯(pi)料(liao)經冷(leng)彎曲(qu)加(jia)工成型(xing)后(hou)再(zai)經高頻焊接制成的(de)(de)方形截面(mian)形狀尺寸的(de)(de)空心方形的(de)(de)截面(mian)型(xing)鋼(gang)鋼(gang)管；鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)卷或(huo)(huo)將事先做好的(de)(de)冷(leng)彎空心型(xing)鋼(gang)管再(zai)經熱(re)浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)加(jia)工而成的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)方矩(ju)管。鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量是(shi)表示鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板鋅(xin)(xin)(xin)層厚度的(de)(de)一(yi)(yi)個(ge)普遍采用(yong)的(de)(de)有效方法。鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量的(de)(de)單(dan)位為(wei)g/m2。鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)層通過鈍(dun)化處理(li)，可減少潮溫貯運條(tiao)件(jian)下(xia)產生折銹蝕(shi)(白銹) 。但(dan)這種化學處理(li)的(de)(de)防腐蝕(shi)性(xing)能是(shi)有限(xian)的(de)(de)，而且(qie)，妨(fang)礙大多數涂料(liao)的(de)(de)附著性(xing)。這種處理(li)一(yi)(yi)般不(bu)用(yong)在鋅(xin)(xin)(xin)鐵合金鍍(du)(du)(du)(du)層，除光整(zheng)表面(mian)外，作為(wei)常規，生產廠對其他(ta)類型(xing)的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)層均進行鈍(dun)化處理(li)。
