style="text-indent:25px">鍍鋅扁鋼，是指寬12-300mm、厚4-60mm、截面為長(zhǎng)方形并稍帶純邊的鍍鋅鋼材。鍍鋅扁鋼可以是成品鋼材，也可以做鍍鋅管的坯料和鍍鋅帶。鍍鋅扁鋼作為成材可用于制箍鐵、工具及機(jī)械零件，建筑上用作房架結(jié)構(gòu)件、扶梯。鍍鋅工藝熱鍍鋅也叫熱浸鋅和熱浸鍍鋅：是一種有效的金屬防腐方式，主要用于各行業(yè)的金屬結(jié)構(gòu)設(shè)施上。是將除銹后的鋼件浸入500℃左右融化的鋅液中，使鋼構(gòu)件表面附著鋅層，從而起到防腐的目的。熱鍍鋅工藝流程：成品酸洗-水洗-加助鍍液-烘干-掛鍍-冷卻-藥化-清洗-打磨-熱鍍鋅完工熱鍍鋅是由較古老的熱鍍方法發(fā)展而來(lái)的，自從1836年法國(guó)把熱鍍鋅應(yīng)用于工業(yè)以來(lái)，已經(jīng)有一百四十年的歷史了。然而，熱鍍鋅工業(yè)是近三十年來(lái)伴隨冷軋帶鋼的飛速發(fā)展而得到了大規(guī)模發(fā)展。鍍鋅扁鋼采用齒盤(pán)全浸式半自動(dòng)鍍鋅方式撥入、壓下、螺旋、拔出、提升的機(jī)械原理，完成鍍鋅扁鋼過(guò)程。</p><div

1.吹鍍跟掛鍍是同種鍍鋅方法，俗稱(chēng)掛鍍，人工掛鍍熱軋鋼結(jié)構(gòu)為主，效率較低切鋅層不均勻，機(jī)械掛鍍優(yōu)于人工掛鍍，對(duì)環(huán)境污染大。 </p> <p> 2.熱浸鍍鋅，俗稱(chēng)熱鍍鋅，就是把東西在鍍鋅溶液中浸泡形成鍍層。 </p> <p> 3.電鍍鋅就是俗稱(chēng)的冷鍍，表面精致，污染少，優(yōu)點(diǎn)非常多，不勝枚舉，比較大的缺點(diǎn)：價(jià)格高。 </p> <p> 這樣說(shuō)您可能不是很清楚，就那40*5的鍍鋅扁鋼來(lái)說(shuō)吧，滾鍍的一噸要3000塊錢(qián)，但您要是要掛鍍的那就不是這些錢(qián)了，這個(gè)一噸要3750，這樣說(shuō)您就明白了吧。掛鍍也有貴的價(jià)值，掛鍍的扁鋼使用時(shí)間更長(zhǎng)。機(jī)械掛鍍優(yōu)于人工掛鍍，對(duì)環(huán)境污染大。昆明質(zhì)量鍍鋅扁鋼報(bào)價(jià)</p><p
