熱(re)(re)鍍(du)鋅(xin)(xin)(xin)卷板(ban)現(xian)貨消(xiao)息：熱(re)(re)鍍(du)鋅(xin)(xin)(xin)產品廣泛用于建(jian)筑(zhu)、家電、車船、容器制造(zao)業、機電業等，幾(ji)乎涉及到(dao)衣食住行(xing)各個領域。近年來(lai)，世界鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)需求量(liang)不(bu)斷(duan)增加(jia)，產量(liang)增長也很快(kuai)，在(zai)美(mei)、日等鋼(gang)材生產大(da)國，熱(re)(re)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)在(zai)鋼(gang)材中(zhong)所占比例已高達13%-15%。 熱(re)(re)鍍(du)鋅(xin)(xin)(xin)卷板(ban)現(xian)貨消(xiao)息：近來(lai)，汽(qi)車行(xing)業越來(lai)越重視材料的使用壽命，用涂漆冷軋鋼(gang)板(ban)已不(bu)能(neng)滿足耐腐蝕方面的要求。在(zai)這(zhe)種情況下(xia)，耐腐蝕性優(you)良且成本低廉的熱(re)(re)鍍(du)鋅(xin)(xin)(xin)板(ban)開始(shi)普遍(bian)受到(dao)了汽(qi)車廠家的青睞。

重慶鍍(du)(du)鋅(xin)(xin)板(ban)近(jin)二十年來鋼(gang)(gang)帶連續(xu)熱鍍(du)(du)鋅(xin)(xin)技(ji)(ji)(ji)術(shu)(shu)、裝(zhuang)備以(yi)及相應的(de)控制(zhi)手(shou)段均有巨大(da)(da)的(de)發(fa)(fa)展(zhan)，使鍍(du)(du)鋅(xin)(xin)板(ban)得以(yi)滿足汽車(che)面板(ban)和(he)家電用板(ban)的(de)苛刻要求，并(bing)從而以(yi)其(qi)比(bi)電鍍(du)(du)鋅(xin)(xin)合(he)(he)金鋼(gang)(gang)帶廉價、耐(nai)蝕性優異(yi)而大(da)(da)有取代之勢。熱鍍(du)(du)鋅(xin)(xin)生產(chan)(chan)技(ji)(ji)(ji)術(shu)(shu)與裝(zhuang)備開發(fa)(fa)技(ji)(ji)(ji)術(shu)(shu)及經驗，通(tong)過(guo)技(ji)(ji)(ji)術(shu)(shu)創新、優化設計、精(jing)密制(zhi)造以(yi)及國外(wai)技(ji)(ji)(ji)術(shu)(shu)合(he)(he)作，突破制(zhi)約我(wo)國高性能汽車(che)用熱鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)生產(chan)(chan)技(ji)(ji)(ji)術(shu)(shu)與裝(zhuang)備發(fa)(fa)展(zhan)瓶(ping)頸(jing)。

綿陽鍍鋅帶鋼重慶鍍鋅卷主要有：脫落、劃傷、鈍化斑、鋅粒、厚邊、氣刀條痕、氣刀刮痕、露鋼、夾雜、機械損傷、鋼基性能不良、浪邊、瓢曲、尺寸不合、壓印、鋅層厚度不合、輥印等。鍍鋅帶鋼批發鋅層(ceng)脫(tuo)落的主要原(yuan)因(yin)有：表(biao)面氧化、有硅化合物、冷扎乳化液(ye)太臟、NOF段氧化氣氛及保護氣體露點太高、空燃比不(bu)合理、氫氣流量偏(pian)低(di)(di)、爐(lu)子有氧滲入，帶鋼入鍋溫度偏(pian)低(di)(di)，RWP段爐(lu)壓(ya)偏(pian)低(di)(di)及爐(lu)門吸風、NOF段爐(lu)溫偏(pian)低(di)(di)，油脂蒸發不(bu)盡、鋅鍋鋁(lv)含量偏(pian)低(di)(di)、機(ji)組速度太快、還原(yuan)不(bu)充分、鋅液(ye)中停留時(shi)間(jian)太短、鍍(du)(du)層(ceng)偏(pian)厚。白銹和黑斑產生(sheng)的原(yuan)因(yin)有：黑斑是白銹進一(yi)步(bu)氧化形成的鍍(du)(du)鋅板的特(te)(te)點與用途。鍍(du)(du)鋅卷板是以熱(re)軋鋼帶或冷軋鋼帶為基板，經過連續熱(re)浸(jin)鍍(du)(du)鋅工(gong)(gong)藝而生(sheng)產出來的， 產品具有耐腐蝕強、 表(biao)面質量好、有利于深加(jia)工(gong)(gong)、經濟實用等特(te)(te)點。

由于(yu)我國鋅(xin)資源(yuan)比較豐(feng)富，鍍鋅(xin)又是一種價廉、能防銹，又能裝飾的高(gao)性(xing)價比鍍種，因(yin)而(er)在汽(qi)車、機械、電子、船舶(bo)、儀表(biao)、輕(qing)工(gong)等(deng)工(gong)業部門(men)得到(dao)廣(guang)泛的應用。如機械零件、低壓(ya)電器(qi)、高(gao)壓(ya)開(kai)關、緊固連接件、鋼(gang)鐵結構件、建筑五(wu)金、農業機械、輕(qing)工(gong)產品(pin)等(deng)都離不開(kai)鍍鋅(xin)鈍(dun)化制(zhi)品(pin)。鍍鋅(xin)板卷(juan)因(yin)此可分為(wei)熱軋鍍鋅(xin)板卷(juan)和冷(leng)軋熱鍍鋅(xin)板卷(juan)，它們主要用于(yu)建筑、家(jia)電、汽(qi)車、容(rong)器(qi)、交通及(ji)家(jia)業等(deng)領(ling)域。特別是鋼(gang)結構建筑、汽(qi)車制(zhi)造、鋼(gang)板倉制(zhi)造等(deng)行業。 重慶(qing)鍍鋅(xin)卷(juan)特點主要為(wei)：耐腐(fu)蝕強、表(biao)面質量好、得利于(yu)深加工(gong)、經濟(ji)實用等(deng)。
