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度完成再結晶退火，經(jīng)冷卻段控制進鋅鍋前溫度在480度左右，在不接觸空氣的情況下進入鋅鍋鍍鋅，因此，森吉米爾法產(chǎn)量高、鍍鋅質量較好，此法曾得到廣泛應用。呈貢區(qū)鍍鋅圓鋼泰國鍍鋅圓鋼價格，云南貿(mào)軒商貿(mào)有限公司。</p><div

</p><p> 熱鍍鋅圓鋼的工藝流程分析，如下： </p> <p> 單支鋼材 </p> <p> 這種方法一般是采用熱軋疊軋板作為原料，首先把經(jīng)過退火的鋼材送入酸洗車間,用硫酸或鹽酸清理鋼材表面的氧熱鍍鋅法化鐵皮。酸洗之后的鋼材立即進入水箱中浸泡等待鍍鋅，這樣可以防止鋼材再氧化。后經(jīng)過酸洗、水清洗、擠干、烘干、進入鋅鍋(溫度一直保持在445—465℃)熱鍍鋅，再進行涂油和鉻化處理。這種方法生產(chǎn)的熱鍍鋅板比濕法鍍鋅成品質量有明顯提高，只對小規(guī)模生產(chǎn)有一定價值。 </p> <p> 惠林法熱 </p> <p> 該連續(xù)鍍鋅生產(chǎn)線包括堿液脫脂、鹽酸酸洗、水沖洗、涂溶劑、烘干等一系列前處理工序，而且原板進入鍍鋅線鍍鋅前還需要進行罩式爐退火。這種方法生產(chǎn)工藝復雜，生產(chǎn)成本高，更為主要的是此方法生產(chǎn)的產(chǎn)品常常帶有溶劑缺點，影響鍍層的耐蝕性。并且鋅鍋中的AL常常和鋼材表面的溶劑發(fā)生作用生成三氯化鋁而耗掉，鍍層的粘附性變壞。因而此方法雖然已問世近三十年，但在世界熱鍍鋅行業(yè)中并未得到發(fā)展。熱鍍鋅圓鋼是指截面為圓形的實心長條鋼材。</p><div

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。在原板進入作業(yè)線后，首先進行電解脫脂，而后水洗、烘干，再通過有保護氣體的還原爐進行再結晶退火，在密封情況下進入鋅鍋熱鍍鋅。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，可適當降低還原爐中保護氣體的氫含量。這樣，對爐安全和降低生產(chǎn)成本有利。但是，由于帶鋼得不到預加熱就進入還原爐中，這樣無疑提高了還原爐的熱負荷，影響爐子的壽命。因此這種方法并未得廣泛應用。緬甸鍍鋅圓鋼價格，云南貿(mào)軒商貿(mào)有限公司。西山區(qū)鍍鋅圓鋼</p><p
