重慶鍍(du)鋅(xin)(xin)(xin)卷主(zhu)要(yao)有：脫(tuo)落(luo)、劃傷、鈍化斑(ban)、鋅(xin)(xin)(xin)粒、厚(hou)(hou)邊(bian)、氣(qi)刀條痕(hen)、氣(qi)刀刮痕(hen)、露鋼(gang)、夾雜、機(ji)械損傷、鋼(gang)基(ji)性能(neng)不(bu)良(liang)、浪邊(bian)、瓢曲(qu)、尺寸不(bu)合(he)、壓(ya)印、鋅(xin)(xin)(xin)層(ceng)厚(hou)(hou)度不(bu)合(he)、輥印等。鋅(xin)(xin)(xin)層(ceng)脫(tuo)落(luo)的(de)主(zhu)要(yao)原(yuan)因(yin)有：表(biao)面(mian)氧(yang)化、有硅(gui)化合(he)物、冷(leng)扎乳化液太臟、NOF段氧(yang)化氣(qi)氛及(ji)保護氣(qi)體露點太高、空燃比不(bu)合(he)理、氫氣(qi)流量(liang)偏(pian)(pian)低(di)、爐(lu)子(zi)有氧(yang)滲入，帶鋼(gang)入鍋(guo)溫度偏(pian)(pian)低(di)，RWP段爐(lu)壓(ya)偏(pian)(pian)低(di)及(ji)爐(lu)門吸風、NOF段爐(lu)溫偏(pian)(pian)低(di)，油(you)脂(zhi)蒸(zheng)發不(bu)盡、鋅(xin)(xin)(xin)鍋(guo)鋁含量(liang)偏(pian)(pian)低(di)、機(ji)組(zu)速(su)度太快、還原(yuan)不(bu)充分、鋅(xin)(xin)(xin)液中停留時(shi)間(jian)太短、鍍(du)層(ceng)偏(pian)(pian)厚(hou)(hou)。白銹(xiu)和黑斑(ban)產(chan)生(sheng)的(de)原(yuan)因(yin)有：黑斑(ban)是白銹(xiu)進(jin)一步氧(yang)化形(xing)成的(de)鍍(du)鋅(xin)(xin)(xin)板(ban)的(de)特(te)點與用途。鍍(du)鋅(xin)(xin)(xin)卷板(ban)是以熱(re)軋(ya)鋼(gang)帶或冷(leng)軋(ya)鋼(gang)帶為(wei)基(ji)板(ban)，經過連(lian)續熱(re)浸鍍(du)鋅(xin)(xin)(xin)工藝而生(sheng)產(chan)出來的(de)， 產(chan)品具有耐(nai)腐蝕(shi)強、 表(biao)面(mian)質量(liang)好、有利于(yu)深加工、經濟實用等特(te)點。

熱鍍(du)(du)(du)(du)鋅板(ban)和電(dian)鍍(du)(du)(du)(du)鋅板(ban)在鍍(du)(du)(du)(du)鋅量上有很(hen)大(da)(da)的(de)(de)差(cha)別，就像(xiang)山(shan)東彩涂卷）。熱鍍(du)(du)(du)(du)鋅的(de)(de)鍍(du)(du)(du)(du)鋅量不可(ke)能(neng)太小(xiao)，一般較小(xiao)為(wei)雙面50～60g／m2，較大(da)(da)可(ke)達(da)600g／m2。電(dian)鍍(du)(du)(du)(du)鋅板(ban)的(de)(de)鍍(du)(du)(du)(du)鋅層可(ke)以很(hen)薄，較小(xiao)達(da)15g／m2，但要求鍍(du)(du)(du)(du)層較厚的(de)(de)話則生產線速(su)度很(hen)慢，不適(shi)應(ying)現代化機組的(de)(de)工藝特點，一般較大(da)(da)為(wei)lO0g／m2左右。正因為(wei)如此，電(dian)鍍(du)(du)(du)(du)鋅板(ban)的(de)(de)生產受到很(hen)大(da)(da)的(de)(de)限制。工一般電(dian)鍍(du)(du)(du)(du)鋅比較多，適(shi)用(yong)于小(xiao)部(bu)件(jian)；熱鍍(du)(du)(du)(du)鋅一般用(yong)于電(dian)力設(she)備和構件(jian)，適(shi)用(yong)于大(da)(da)的(de)(de)部(bu)件(jian)和設(she)備。當然他(ta)們的(de)(de)價格也(ye)相對便宜一些。建設(she)部(bu)已正式下文(wen)，淘汰技(ji)術落后(hou)的(de)(de)冷鍍(du)(du)(du)(du)鋅管，不準用(yong)冷鍍(du)(du)(du)(du)鋅管作水、煤(mei)氣(qi)管。

四川鍍鋅近期鋼價延續低迷，隨著通國規模的酷暑和旱季到來，熱鍍鋅卷板價格商場逐漸進入需要旺季，海內鋼鐵商場或將窄幅調整。在決策層兩手抓制度措施落實狀況、貨銀本位度定向寬松力度加大的直觀層面利好牽動下，商場信念逐漸趨穩，短期海內鋼價無望止跌企穩;另一上面，以后鋼價殺跌電能有余，而上漲也仍然屏障重重。鍍鋅價格熱鍍鋅卷板價格(ge)價錢(qian)或將長期在于低(di)位(wei)運行場面。

由于(yu)我國鋅(xin)資源比較(jiao)豐富，鍍(du)鋅(xin)又是(shi)一種價廉(lian)、能防銹，又能裝飾(shi)的高(gao)性價比鍍(du)種，因而在汽(qi)(qi)車、機械(xie)、電(dian)子、船舶(bo)、儀表、輕工(gong)(gong)等(deng)工(gong)(gong)業部門得(de)到廣泛(fan)的應用。如機械(xie)零件、低壓電(dian)器(qi)、高(gao)壓開關、緊固連接件、鋼(gang)鐵結構件、建筑五(wu)金、農業機械(xie)、輕工(gong)(gong)產品等(deng)都離不(bu)開鍍(du)鋅(xin)鈍化制(zhi)(zhi)品。鍍(du)鋅(xin)板(ban)卷(juan)(juan)因此可分(fen)為熱(re)軋鍍(du)鋅(xin)板(ban)卷(juan)(juan)和(he)冷軋熱(re)鍍(du)鋅(xin)板(ban)卷(juan)(juan)，它們主(zhu)要用于(yu)建筑、家電(dian)、汽(qi)(qi)車、容(rong)器(qi)、交通及家業等(deng)領域(yu)。特別是(shi)鋼(gang)結構建筑、汽(qi)(qi)車制(zhi)(zhi)造、鋼(gang)板(ban)倉制(zhi)(zhi)造等(deng)行(xing)業。 重慶鍍(du)鋅(xin)卷(juan)(juan)特點主(zhu)要為：耐腐蝕(shi)強、表面質量好、得(de)利(li)于(yu)深加工(gong)(gong)、經濟實(shi)用等(deng)。
