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)模生產有一定價值。 </p> <p> 惠林法熱 </p> <p> 該連續(xù)鍍鋅生產線包括堿液脫脂、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。這種方法生產工藝復雜，生產成本高，更為主要的是此方法生產的產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。 </p><p> 鍍鋅圓鋼及對表面鍍鋅層都有哪些要求？ </p> <p> 鍍鋅圓鋼一般指建筑安裝時用在避雷接地的接線，用普通圓鋼（通常為直徑8mm至12mm）經(jīng)電鍍鋅保護層得到。鍍鋅分化學鍍與電鍍、冷鍍鋅與熱鍍鋅等。 </p> <p> 鍍鋅圓鋼就是熱軋光圓，經(jīng)除銹、酸洗、熱浸、電化鍍鋅于表層，成為不易生銹的鋼筋。我們用來輸送自來水的白鐵管（俗稱）也是焊接鋼管熱浸鍍鋅而成的‘鍍鋅鋼管’。 </p> <p> 除銹、酸洗、熱浸、電化鍍鋅的原理、達到不易生銹的道理， </p> <p> 鍍鋅層均勻沒有漏鍍的地方，沒有鋅疙瘩，鍍鋅層應該符合相應國家標準要求，如鋅層不小于250克/平米，鍍鋅層厚度的大小直接決定圓鋼防腐蝕能力.

二、冷拉強化的原理：鋼材在塑性變形中晶格的缺點增多，而缺點的晶格嚴重畸變對晶格進一步滑移將起到阻礙作用，故鋼材的屈服點提高，塑性和韌性降低。由于塑性變形中產生內應力，故鋼材的彈性模量降低。將經(jīng)過冷拉的鋼筋于常溫下存放15～20d或加熱到100～200℃并保持一定時間，這個過程稱為時效處理。 </p> <p> 三、冷拉后時效處理的鋼筋，屈服點進一步提高，抗拉極限強度也有所增長，塑性繼續(xù)降低。由于時效過程中內應力的消減，故彈性模量可基本恢復。工地或預制構件廠常利用這一原理，對鋼筋或低碳鋼盤條按一定制度進行冷拉或冷拔加工，以提高屈服強度節(jié)約鋼材。熱鍍鋅圓鋼的材質檢測是怎樣的？昆明鍍鋅圓鋼</p><p
