這種方法一般是采用熱軋疊軋板作為原料，首先把經(jīng)過退火的鋼板送入酸洗車間,用硫酸或鹽酸***鋼板表面的氧化鐵皮。酸洗之后的鋼板立即進(jìn)入水箱中浸泡等待鍍鋅,這樣可以防止鋼板再氧化。后經(jīng)過酸洗、水清洗、擠干、烘干、進(jìn)入鋅鍋（溫度一直保持在445—465℃）熱鍍鋅，再進(jìn)行涂油和鉻化處理。這種方法生產(chǎn)的熱鍍鋅板比濕法鍍鋅成品質(zhì)量有***提高，只對小規(guī)模生產(chǎn)有一定價值。

酸性鍍鋅工藝中還有一種硫酸鹽鍍鋅工藝。它的主要成分是主鹽硫酸鋅。含量在250-500g/L之間。明礬或硫酸鋁作導(dǎo)電鹽。含量在30-50g/L之間。導(dǎo)電鹽也有加入硫酸鈉或氯化鈉的。除了上述幾種外，還要加入一些添加劑，作用是使鍍層細(xì)致。**早是采用糊精或樹膠，后來發(fā)明了一些**光亮劑使鍍層更加光亮細(xì)致。硫酸鹽鍍鋅的比較大優(yōu)點(diǎn)是可使用較大電流密度(1-5A/dm2)，鍍速快。但缺點(diǎn)是鍍液的分散能力很差，不宜用來鍍較復(fù)雜工件。 </p> <p> 由于它的特殊性，硫酸鹽鍍鋅主要用在鍍鐵絲、鋼帶、鋼板等形狀簡單，連續(xù)化生產(chǎn)性強(qiáng)的行業(yè)。除了上述幾種常用的鍍鋅工藝外，還有焦磷酸鹽鍍鋅、氟硼酸鹽鍍鋅、羥酸鹽鍍鋅等工藝，但應(yīng)用不多，不再介紹。 </p><p> 硫氰酸鉀熱鍍鋅的轉(zhuǎn)換 </p> <p> 硫氰酸鉀磷化處理有色金屬只保存硫氰酸鉀熱鍍鋅的主鹽硫酸鋅，其他成分如硫酸鋁、食用堿(硫酸鋁鉀)等可在鍍液解決時，添加燒堿使之轉(zhuǎn)化成不可溶氫氧化物沉定除去;對有機(jī)化學(xué)防腐劑，則添**狀活性炭吸附除去。實(shí)驗(yàn)說明，硫酸鋁與硫酸鋁鉀一次性無法完全除去，對涂層光澤度有危害，但并不是比較嚴(yán)重，可攜帶出耗費(fèi)，這時涂層光澤度便可修復(fù)水溶液根據(jù)解決，可按新技術(shù)新工藝需要成份含水量加補(bǔ)，即進(jìn)行轉(zhuǎn)換。 </p> <p> 硫氰酸鉀磷化處理有色金屬加工工藝電流效率達(dá)到100 %，堆積速度快是一切熱鍍鋅加工工藝無法比擬的，精細(xì)管的運(yùn)作速率8～12m/min，涂層薄厚均值2m/min，它是持續(xù)熱鍍鋅難以超過的。涂層明亮細(xì)膩舒目。按國家行業(yè)標(biāo)準(zhǔn)GB/T10125“人工合成氛圍實(shí)驗(yàn)-鹽霧測試”方式檢測，72h，涂層完好無損、無轉(zhuǎn)變;96h，涂層表層出現(xiàn)小量白銹。

它是把退火工藝和熱鍍鋅工藝聯(lián)合起來，其線內(nèi)退火主要包括氧化爐，還原爐兩部份組成。帶鋼在氧化爐中煤氣火焰直接加熱到450度左右，把帶鋼表面殘存的軋制油燒掉，凈化表面。后再把帶鋼加熱到700-800度完成再結(jié)晶退火，經(jīng)冷卻段控制進(jìn)鋅鍋前溫度在480度左右，***在不接觸空氣的情況下進(jìn)入鋅鍋鍍鋅，因此，森吉米爾法產(chǎn)量高、鍍鋅質(zhì)量較好，此法曾得到廣泛應(yīng)用。

在加工熱鍍鋅鋼帶的時候，您都遇到過哪些質(zhì)量問題？又是如何解決的呢？接下來，熱鍍鋅帶鋼廠家就來為您介紹一下有關(guān)沉沒輥鋅疤的問題。 </p> <p> 什么是沉沒輥鋅疤？就是在熱鍍鋅鋼帶的表面沉陷出來的一些不規(guī)則分布的扁平鋅渣結(jié)疤。這種缺陷只存在于帶鋼上表面，也是它與其它原因造成的鋅疤的區(qū)別。熱鍍鋅帶鋼表面出現(xiàn)這類缺陷，主要是因?yàn)樵谏a(chǎn)過程中，鋅鍋里面有太多底渣積存，當(dāng)帶鋼通過鋅鍋時，這些鋅渣都被沉沒輥壓到帶鋼表面，由此形成了鋅疤缺陷。 </p> <p> 在加工帶鋼的過程中，沉沒輥和帶鋼自檢的擠壓力非常強(qiáng)，所以鋅疤在帶鋼表面粘附得也很牢固，這些帶鋼通過氣刀時，就很難被吹掉。如果在加工熱鍍鋅帶鋼的過程中發(fā)現(xiàn)這種缺陷，工作人員需要及時撈取鋅鍋底渣，并且用刮鋅器將沉沒輥表面刮干凈。濟(jì)寧市批發(fā)鍍鋅槽鋼哪里有</p><p
