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(jìn)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(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)量有明顯提高，只對(duì)小規(guī)模生產(chǎn)有一定價(jià)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(jìn)入鍍鋅線鍍鋅前還需要進(jìn)行罩式爐退火。這種方法生產(chǎn)工藝復(fù)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(diǎn)，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。

熱鍍鋅圓鋼長度尺寸是各種鋼材的基本尺寸，是指鋼材的長、寬、高、直徑、半徑、內(nèi)徑、外徑以及壁厚等長度。其中熱鍍鋅圓鋼的范圍定尺是節(jié)省材料的一種有效措施，就是長度或長乘寬不小于某種尺寸，或是長度、長乘寬從多少到多少的尺寸范圍內(nèi)交貨。 </p> <p> 凡熱鍍鋅圓鋼的尺寸在標(biāo)準(zhǔn)規(guī)定范圍內(nèi)，而又不要求固定尺寸的稱之為不定尺，又可以被稱為通常長度，按不定尺交貨的金屬材料，只要在規(guī)定長度范圍內(nèi)交貨就可以了。熱鍍鋅圓鋼定尺按訂貨要求切成固定尺寸的稱為定尺。按定尺長度交貨時(shí)，所交金屬材料必須具有需方在訂貨合同中指定的長度。 </p><div
