它是森吉米爾法的一個變種，它**是利用一個堿性電解脫脂槽取代了氧化爐的脫脂作用，其余工序與森吉米爾法基本相同。在原板進(jìn)入作業(yè)線后，首先進(jìn)行電解脫脂，而后水洗、烘干，再通過有保護(hù)氣體的還原爐進(jìn)行再結(jié)晶退火，在密封情況下進(jìn)入鋅鍋熱鍍鋅。這種方法因帶鋼不經(jīng)過氧化爐加熱，所以表面的氧化膜較薄，可適當(dāng)降低還原爐中保護(hù)氣體的氫含量。這樣，對爐安全和降低生產(chǎn)成本有利。但是，由于帶鋼得不到預(yù)加熱就進(jìn)入還原爐中，這樣無疑提高了還原爐的熱負(fù)荷，影響爐子的壽命。因此這種方法并未得***應(yīng)用。 </p><p> 熱鍍鋅圓鋼的工藝流程分析，如下： </p> <p> <br /> </p> <p> 莎倫法 </p> <p> 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)的整個退火爐構(gòu)成一個有機(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。鋼材中的線材和圓鋼是完全不同的兩種材料。</p><div
