<p> 熱鍍鋅圓鋼是指截面為圓形的實心長條鋼材。其規(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。 </p> <p> 化學(xué)成分：C0，呈貢區(qū)鍍鋅圓鋼.42-0.50Si0.17-0.37Mn0.50-0，呈貢區(qū)鍍鋅圓鋼.80Cr不大于0.25Ni不大于0.30Cu不大于0.25力學(xué)性能：抗拉強度不小于600Mpa，屈服強度不小于355Mpa，延伸率不小于16，斷面收縮率不小于40%，沖擊功不小于31J。未熱下HBS10/3000不大于229.推薦熱處理溫度：正火850攝氏度。淬火840攝氏度，回火600攝氏度，呈貢區(qū)鍍鋅圓鋼。 </p> <p> 鍍鋅圓鋼的鍍鋅層均勻沒有漏鍍的地方，沒有鋅疙瘩，鍍鋅層應(yīng)該符合相應(yīng)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 </p> <p> <br /> 熱鍍鋅的鍍層較厚，一般為30-60微米，鍍層防腐能力較高。呈貢區(qū)鍍鋅圓鋼</p><div style="width:100%;text-align:

<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(xué)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(yīng)該符合相應(yīng)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. </p> <p> 鍍鋅圓鋼的符號是什么 </p> <p> SC--焊接鋼管 </p> <p> MT--電線管（還看見用TC--標注為電線管的） </p> <p>

1939年美國莎倫公司投產(chǎn)一臺新型的熱鍍鋅機組，所以也叫莎倫法。該法是在退火爐內(nèi)向帶鋼噴射氯化氫氣體并使帶鋼達到再結(jié)晶溫度，所以也稱為氣體酸洗法。采用氯化氫氣體酸洗，不但能去除帶鋼表面的氧化皮，而且同時去除了帶鋼表面的油脂，由于帶鋼表面被氧化氣體腐蝕，形成麻面，所以使用莎倫法所得到的鍍層粘附性特別好。但是由于設(shè)備腐蝕嚴重，由此造成很高的設(shè)備維修和更新費用。因而此種方法很少被采用。 </p> <p> 改良森吉米 </p> <p> 它是一種更優(yōu)越的熱鍍鋅工藝方法;它把森吉米爾法中各自**的氧化爐和還原爐由一個截面積較小的過道連接起來，這樣包括預(yù)熱爐、還原爐和冷卻段在內(nèi)的整個退火爐構(gòu)成一個有機整體。實踐證明，該法具有許多優(yōu)點：質(zhì)量、高產(chǎn)、低耗、安全等優(yōu)點已逐漸被人們所認識。其發(fā)展速度非?？?，1965年以來新建的作業(yè)線幾乎全部采用了這種方法，近年來老的森吉米爾機組也大都按照此方法進行了改造。
