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廣泛應(yīng)用。鍍鋅圓鋼規(guī)格以直徑的毫米數(shù)表示，如“50”即表示直徑為50毫米的圓鋼。昆明質(zhì)量鍍鋅圓鋼規(guī)格尺寸</p><p

線外退火就是熱軋或冷軋鋼進(jìn)入熱鍍鋅作業(yè)線之前，首先在抽底式退火爐或罩式退火爐中進(jìn)行再結(jié)晶退火，這樣，鍍鋅線就不存在退火工序了。鋼材在熱鍍鋅之前必須保持一個無氧化物和其他臟物存在的潔凈的純鐵活性表面。這種方法是先由酸洗的方法把經(jīng)退火的表面氧化鐵皮清理，然后涂上一層由氯化鋅或由氯化銨和氯化鋅混合組成的溶劑進(jìn)行保護(hù)，從而防止鋼材再被氧化。 </p> <p> 濕法熱鍍鋅 </p> <p> 鋼材表面的溶劑不經(jīng)烘干(即表面還是濕的)就進(jìn)入起表面覆蓋有熔融態(tài)溶劑的鋅液進(jìn)行熱鍍鋅。此方法的缺點(diǎn)是： </p> <p> a.只能在無鉛狀態(tài)下鍍鋅，鍍層的合金層很厚且粘附性很壞; </p> <p> b.生成的鋅渣都積存在鋅液和鉛液的界面處而不能沉積鍋底(因?yàn)殇\渣的比重大于鋅液而小于鉛液)，這樣鋼材因穿過鋅層污染了表面。 </p> <p> 因此，濕法熱鍍鋅已基本被淘汰。昆明質(zhì)量鍍鋅圓鋼生產(chǎn)廠家</p><p
