白鐵價格熱鍍鋅卷板價格行業統計數據顯示，十一月國內粗鋼日均產量為兩百零九萬噸，環比下降3.3%，創出今年以來水平，但是當前減產受到季節性因素支撐，市場對數據有效性提出質疑。大足白鐵鍍(du)鋅(xin)卷工(gong)業品而言，近期陸(lu)續公布的重(zhong)要數據(ju)中性偏多。但值得注(zhu)意的是(shi)，同年十一月熱鍍(du)鋅(xin)卷板(ban)價格工(gong)業增(zeng)(zeng)加值和投(tou)資增(zeng)(zeng)速(su)放緩，進一步(bu)印(yin)證(zheng)了國內總(zong)需(xu)(xu)求(qiu)乏力(li)，工(gong)業復蘇(su)形勢不(bu)容樂觀。加上未(wei)來經(jing)濟(ji)結構調整等因素，工(gong)業品價格反彈(dan)高度將有限。傳(chuan)統需(xu)(xu)求(qiu)淡(dan)季(ji)效(xiao)(xiao)應還在持(chi)續不(bu)斷地(di)發酵，冬儲效(xiao)(xiao)果不(bu)佳(jia)。雖(sui)然(ran)數據(ju)顯示供應壓力(li)開始減輕，但是(shi)目前處于鋼鐵需(xu)(xu)求(qiu)淡(dan)季(ji)，市(shi)場成交萎縮，下游采購遲(chi)遲(chi)未(wei)能(neng)有效(xiao)(xiao)跟進，市(shi)場信(xin)心不(bu)足，鍍(du)鋅(xin)鋼板(ban)貿易商(shang)囤貨現象(xiang)也(ye)不(bu)明顯。

鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)是為防止鋼(gang)(gang)板(ban)(ban)(ban)表面(mian)遭(zao)受(shou)腐蝕，延長其使用壽命，在鋼(gang)(gang)板(ban)(ban)(ban)表面(mian)涂(tu)以一層金(jin)(jin)屬鋅(xin)(xin)(xin)(xin)，這(zhe)(zhe)種(zhong)涂(tu)鋅(xin)(xin)(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)稱為鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)。按生產(chan)及加工方(fang)法可分(fen)為以下(xia)幾類：熱浸(jin)(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)浸(jin)(jin)入(ru)熔 微商貨源解的(de)(de)鋅(xin)(xin)(xin)(xin)槽(cao)(cao)中(zhong)，使其表面(mian)粘附一層鋅(xin)(xin)(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)。目前主要采用連續(xu)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)工藝生產(chan)，即把(ba)成(cheng)卷(juan)的(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)連續(xu)浸(jin)(jin)在熔解有鋅(xin)(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)槽(cao)(cao)中(zhong)制成(cheng)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)；合(he)(he)金(jin)(jin)化鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。這(zhe)(zhe)種(zhong)鋼(gang)(gang)板(ban)(ban)(ban)也是用熱浸(jin)(jin)法制造，但在出槽(cao)(cao)后，立(li)即把(ba)它加熱到５００℃左右，使其生成(cheng)鋅(xin)(xin)(xin)(xin)和鐵的(de)(de)合(he)(he)金(jin)(jin)被膜。這(zhe)(zhe)種(zhong)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)具有良好的(de)(de)涂(tu)料的(de)(de)密著性和焊接性。
