1939年美國(guó)莎倫公司投產(chǎn)一臺(tái)新型的熱鍍鋅機(jī)組，所以也叫莎倫法。該法是在退火爐內(nèi)向帶鋼噴射氯化氫氣體并使帶鋼達(dá)到再結(jié)晶溫度，所以也稱(chēng)為氣體酸洗法。采用氯化氫氣體酸洗，不但能去除帶鋼表面的氧化皮，而且同時(shí)去除了帶鋼表面的油脂，由于帶鋼表面被氧化氣體腐蝕，形成麻面，所以使用莎倫法所得到的鍍層粘附性特別好。但是由于設(shè)備腐蝕嚴(yán)重，由此造成很高的設(shè)備維修和更新費(fèi)用。因而此種方法很少被采用。 </p> <p> 改良森吉米 </p> <p> 它是一種更優(yōu)越的熱鍍鋅工藝方法;它把森吉米爾法中各自**的氧化爐和還原爐由一個(gè)截面積較小的過(guò)道連接起來(lái)，這樣包括預(yù)熱爐、還原爐和冷卻段在內(nèi)的整個(gè)退火爐構(gòu)成一個(gè)有機(jī)整體。實(shí)踐證明，該法具有許多優(yōu)點(diǎn)：質(zhì)量、高產(chǎn)、低耗、安全等優(yōu)點(diǎn)已逐漸被人們所認(rèn)識(shí)。其發(fā)展速度非?？欤?965年以來(lái)新建的作業(yè)線幾乎全部采用了這種方法，近年來(lái)老的森吉米爾機(jī)組也大都按照此方法進(jìn)行了改造。如何計(jì)算12mm鍍鋅圓鋼的重量。昆明質(zhì)量鍍鋅圓鋼價(jià)格查詢(xún)</p><p style="text-indent:25px">熱鍍的表面比較光滑,有光澤,密度大較細(xì)膩。冷鍍的則反之。昆明鍍鋅圓鋼源頭直供廠家</p><p> 熱鍍鋅圓鋼中的鋅含量 </p> <p> <br /> </p> <p> 熱鍍鋅----又稱(chēng)為熱浸鍍鋅，他是在高溫下把鋅錠融化，在放入一些輔助材料，然后把金屬結(jié)構(gòu)件浸入鍍鋅槽中，使金屬構(gòu)件上附著一層鋅層。熱鍍鋅的優(yōu)點(diǎn)在于他的防腐能力強(qiáng)，鍍鋅層的附著力和硬度較好。產(chǎn)品鍍鋅后重量有所增加，我們常說(shuō)的上鋅量，也主要是針對(duì)熱鍍鋅來(lái)說(shuō)的。 </p> <p> 冷鍍”----“電鍍”，即把鋅鹽溶液通過(guò)電解，使鐵離子和鋅離子進(jìn)行置換反映，一般來(lái)說(shuō)不用加熱，上鋅量很少，遇到潮濕環(huán)境很容易生銹。 </p> <p> 當(dāng)熱鍍鋅圓鋼負(fù)載扁鋼厚度不小于5mm時(shí)，鍍鋅厚的平均鋅層重量不小于610g/m2;當(dāng)負(fù)載扁鋼厚度小于5mm時(shí)，鋅層后的平均鋅層重量不小于460g/m2。由于黑件經(jīng)過(guò)酸洗后會(huì)去除表面的銹蝕層，所以經(jīng)過(guò)鍍鋅后并不會(huì)增加扁鋼的厚度，這一點(diǎn)采購(gòu)商要注意，不能以此作為扁鋼是否符合要求的標(biāo)準(zhǔn)。 </p> <p> 熱鍍鋅圓鋼上鋅量的多少，直接影響鋼格板的使用壽命，也是用戶(hù)關(guān)心的問(wèn)題。鍍鋅后質(zhì)量及要求必須符合中國(guó)GB/T13912規(guī)定。熱鍍鋅圓鋼的上鋅量根據(jù)熱鍍鋅圓鋼的扁鋼厚度而言。昆明鍍鋅圓鋼源頭直供廠家</p><p
