熱(re)鍍鋅(xin)(xin)卷板價格(ge)行業(ye)統計數(shu)據(ju)(ju)顯示(shi)，十一(yi)月國(guo)內粗鋼(gang)(gang)日均產量(liang)為兩百零九萬噸，環(huan)比下降(jiang)3.3%，創出(chu)今年以來水平，但是當前減產受到(dao)季節性因素(su)支撐(cheng)，市(shi)場對數(shu)據(ju)(ju)有(you)效性提出(chu)質疑。鍍鋅(xin)(xin)卷工(gong)(gong)業(ye)品(pin)而言，近期陸續公布的重要(yao)數(shu)據(ju)(ju)中性偏(pian)多。但值得注(zhu)意的是，同年十一(yi)月熱(re)鍍鋅(xin)(xin)卷板價格(ge)工(gong)(gong)業(ye)增加(jia)值和投資增速放緩，進一(yi)步印證(zheng)了國(guo)內總(zong)需求乏(fa)力(li)，工(gong)(gong)業(ye)復蘇形勢不(bu)(bu)容樂觀。加(jia)上未來經(jing)濟結構調整(zheng)等(deng)因素(su)，工(gong)(gong)業(ye)品(pin)價格(ge)反彈(dan)高(gao)度將有(you)限。傳統需求淡(dan)季效應還在(zai)持續不(bu)(bu)斷地發酵，冬儲效果不(bu)(bu)佳(jia)。雖(sui)然(ran)數(shu)據(ju)(ju)顯示(shi)供應壓力(li)開始減輕，但是目前處于鋼(gang)(gang)鐵需求淡(dan)季，市(shi)場成交(jiao)萎縮，下游采購遲(chi)遲(chi)未能(neng)有(you)效跟進，市(shi)場信心不(bu)(bu)足，鍍鋅(xin)(xin)鋼(gang)(gang)板貿易商(shang)囤(dun)貨現象(xiang)也不(bu)(bu)明顯。

熱(re)鍍(du)(du)鋅(xin)(xin)(xin)板和(he)電鍍(du)(du)鋅(xin)(xin)(xin)板在鍍(du)(du)鋅(xin)(xin)(xin)量上有很(hen)大(da)的(de)(de)差(cha)別，就像(xiang)山(shan)東(dong)彩涂卷(juan)）。熱(re)鍍(du)(du)鋅(xin)(xin)(xin)的(de)(de)鍍(du)(du)鋅(xin)(xin)(xin)量不可能太小，一(yi)(yi)般(ban)(ban)較(jiao)小為雙面50～60g／m2，較(jiao)大(da)可達600g／m2。電鍍(du)(du)鋅(xin)(xin)(xin)板的(de)(de)鍍(du)(du)鋅(xin)(xin)(xin)層可以很(hen)薄，較(jiao)小達15g／m2，但要求鍍(du)(du)層較(jiao)厚(hou)的(de)(de)話(hua)則(ze)生產線速度很(hen)慢，不適應(ying)現代化機組的(de)(de)工藝特點，一(yi)(yi)般(ban)(ban)較(jiao)大(da)為lO0g／m2左右。正(zheng)因為如此，電鍍(du)(du)鋅(xin)(xin)(xin)板的(de)(de)生產受(shou)到很(hen)大(da)的(de)(de)限(xian)制。工一(yi)(yi)般(ban)(ban)電鍍(du)(du)鋅(xin)(xin)(xin)比較(jiao)多，適用(yong)(yong)于(yu)小部(bu)件(jian)(jian)；熱(re)鍍(du)(du)鋅(xin)(xin)(xin)一(yi)(yi)般(ban)(ban)用(yong)(yong)于(yu)電力設備和(he)構件(jian)(jian)，適用(yong)(yong)于(yu)大(da)的(de)(de)部(bu)件(jian)(jian)和(he)設備。當然(ran)他們的(de)(de)價格也(ye)相(xiang)對便宜一(yi)(yi)些。建(jian)設部(bu)已正(zheng)式下(xia)文，淘(tao)汰技術落(luo)后的(de)(de)冷鍍(du)(du)鋅(xin)(xin)(xin)管，不準用(yong)(yong)冷鍍(du)(du)鋅(xin)(xin)(xin)管作水(shui)、煤氣管。

熱(re)(re)鍍(du)鋅卷板(ban)(ban)(ban)現(xian)貨消息(xi)：熱(re)(re)鍍(du)鋅產(chan)品廣泛用于建筑(zhu)、家電、車船(chuan)、容(rong)器制造業(ye)(ye)、機電業(ye)(ye)等(deng)，幾乎涉及(ji)到(dao)衣食住(zhu)行各(ge)個領(ling)域。近年來(lai)，世界(jie)鍍(du)鋅鋼板(ban)(ban)(ban)需求(qiu)量(liang)不斷增加，產(chan)量(liang)增長也很快，在(zai)美、日等(deng)鋼材(cai)生產(chan)大國，熱(re)(re)鍍(du)鋅鋼板(ban)(ban)(ban)在(zai)鋼材(cai)中(zhong)所占(zhan)比例已高達13%-15%。 熱(re)(re)鍍(du)鋅卷板(ban)(ban)(ban)現(xian)貨消息(xi)：近來(lai)，汽(qi)車行業(ye)(ye)越(yue)來(lai)越(yue)重視材(cai)料的(de)使用壽命，用涂漆冷軋(ya)鋼板(ban)(ban)(ban)已不能滿足耐(nai)腐(fu)蝕方(fang)面的(de)要求(qiu)。在(zai)這種情況下，耐(nai)腐(fu)蝕性優良且成本低(di)廉的(de)熱(re)(re)鍍(du)鋅板(ban)(ban)(ban)開始普遍(bian)受到(dao)了汽(qi)車廠家的(de)青睞。

重慶鍍(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)按生產及加工方法可分為(wei)(wei)以下幾類： 熱浸鍍(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。將薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)浸入熔解的(de)鋅(xin)(xin)(xin)(xin)(xin)槽(cao)中(zhong)，使其表面粘(zhan)附一層鋅(xin)(xin)(xin)(xin)(xin)的(de)薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。目前主要采用(yong)(yong)連續鍍(du)鋅(xin)(xin)(xin)(xin)(xin)工藝生產，即(ji)把成(cheng)卷的(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)連續浸在熔解有鋅(xin)(xin)(xin)(xin)(xin)的(de)鍍(du)槽(cao)中(zhong)制(zhi)成(cheng)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)； 合(he)(he)金(jin)化(hua)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。為(wei)(wei)克(ke)服單(dan)面未涂鋅(xin)(xin)(xin)(xin)(xin)的(de)缺點，又有一種在另面涂以薄層鋅(xin)(xin)(xin)(xin)(xin)的(de)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)，即(ji)雙面差鍍(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)；合(he)(he)金(jin)、復合(he)(he)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。它是(shi)用(yong)(yong)鋅(xin)(xin)(xin)(xin)(xin)和其他金(jin)屬如鉛、鋅(xin)(xin)(xin)(xin)(xin)制(zhi)成(cheng)合(he)(he)金(jin)乃(nai)至復合(he)(he)鍍(du)成(cheng)的(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這種鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)既具有防銹性能，又有良(liang)好(hao)的(de)涂裝性能。

廣西鍍鋅管樓承板鋼結構柱網間距一般5~9.0m×8~15m，次梁間距3m，而樓承板下料長度為4.97~8.97m，運輸與安裝均較困難，尤其是帶由圓弧區垂直吊裝樓承板，由上而下在次梁狹間穿套比較困難，且打亂了次梁焊接正常工序。控制下料長度為3～6m，則可避免垂直運輸時在次梁間無法吊運的問題。 鍍鋅管批發樓(lou)承(cheng)板(ban)(ban)(ban)吊(diao)運時(shi)(shi)(shi)(shi)采(cai)用(yong)專用(yong)軟吊(diao)索。每次吊(diao)裝時(shi)(shi)(shi)(shi)應(ying)(ying)檢查軟吊(diao)索是否(fou)有(you)撕裂、割(ge)斷(duan)現象。樓(lou)承(cheng)板(ban)(ban)(ban)擱(ge)置(zhi)在鋼梁上時(shi)(shi)(shi)(shi)應(ying)(ying)防止探(tan)頭。鋪料時(shi)(shi)(shi)(shi)操作人(ren)員應(ying)(ying)系帶(dai)，并保證邊(bian)(bian)鋪設邊(bian)(bian)固定(ding)在周邊(bian)(bian)繩(sheng)上。 焊(han)接采(cai)用(yong)熔透點焊(han)連接，施焊(han)前應(ying)(ying)準備(bei)邊(bian)(bian)角料引弧試(shi)焊(han)，調(diao)整施焊(han)電流.因樓(lou)承(cheng)板(ban)(ban)(ban)底部(bu)無水平(ping)模板(ban)(ban)(ban)及垂直支撐，澆(jiao)筑混凝(ning)土時(shi)(shi)(shi)(shi)布料不(bu)宜太集中，采(cai)用(yong)平(ping)板(ban)(ban)(ban)振搗(dao)器及時(shi)(shi)(shi)(shi)分攤振搗(dao)。
