1939年美國莎倫公司投產(chǎn)一臺新型的熱鍍鋅機(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)截面積較小的過道連接起來，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。其發(fā)展速度非?？?，1965年以來新建的作業(yè)線幾乎全部采用了這種方法，近年來老的森吉米爾機(jī)組也大都按照此方法進(jìn)行了改造。 </p><p> 鍍鋅圓鋼采用先進(jìn)的熱浸鍍鋅工藝生產(chǎn)，產(chǎn)品表面光華，無漏鍍,無疤點(diǎn),鋅層均勻,附著能力強(qiáng)，鍍鋅圓鋼材質(zhì)符合國家標(biāo)準(zhǔn),具有一定的抗腐蝕能力,可適用于多種行業(yè)。 </p> <p> 在一般的環(huán)境里，鍍鋅圓鋼的熱鍍鋅防銹厚度可保持50年以上而不必修補(bǔ)；在市區(qū)或近海區(qū)域，熱鍍鋅防銹層則可保持20年而不必修補(bǔ)。 </p> <p> 鍍鋅圓鋼的鍍鋅層與鋼材間是冶金結(jié)合，成為鋼表面的一部份，因此鍍鋅圓鋼的鍍層的持久性較為可靠；鍍層的韌性強(qiáng)，鍍鋅層形成一種特別的冶金結(jié)構(gòu)，鍍鋅圓鋼的這種工藝，能較強(qiáng)的承受在運(yùn)送及使用時(shí)受到的機(jī)械損傷；因此我公司的鍍鋅圓鋼受到全國各地廣大用戶的一致好評，歡迎新老客戶來人來電訂購我公司的鍍鋅圓鋼.
