鍍鋅圓鋼是指截面為圓形的實(shí)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。圓鋼分為熱軋、鍛制和冷拉三種。熱軋圓鋼的規(guī)格為5.5-250毫米。其中：5.5-25毫米的小圓鋼大多以直條成捆供應(yīng)，常用作鋼筋、螺栓及各種機(jī)械零件；大于25毫米的圓鋼，主要用于制造機(jī)械零件或作無縫鋼管坯，圓鋼與其它鋼筋的區(qū)別：外型不一樣，圓鋼外型光圓，無紋無肋，其它鋼筋表面外型有刻紋或有肋，這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。成份不一樣，圓鋼(一級(jí)鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。 </p><p> 熱鍍鋅圓鋼的工藝流程分析，如下： </p> <p> <br /> </p> <p> 莎倫法 </p> <p> 1939年美國莎倫公司投產(chǎn)一臺(tái)新型的熱鍍鋅機(jī)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(dá)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(shí)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(yán)重，由此造成很高的設(shè)備維修和更新費(fèi)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(gè)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(gè)退火爐構(gòu)成一個(gè)有機(jī)整體。實(shí)踐證明，該法具有許多優(yōu)點(diǎn)：質(zhì)量、高產(chǎn)、低耗、安全等優(yōu)點(diǎn)已逐漸被人們所認(rèn)識(shí)。其發(fā)展速度非?？欤?965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(jī)組也大都按照此方法進(jìn)行了改造。鍍鋅圓鋼是指截面為圓形的實(shí)心長條鋼材。</p><div

不知道大家有沒有見過圓鋼，比喻一下，大家應(yīng)該都見過蓋樓房所使用的鋼筋，而圓鋼類似于鋼筋，與鋼筋所不同的是，鋼筋是螺旋的外表，外表凹凸不平，而圓鋼的表面就不會(huì)那樣，并且圓鋼與鋼筋的相似點(diǎn)是都是實(shí)心，并且都用于建筑業(yè)，但有些圓鋼會(huì)用于制作機(jī)器設(shè)備。這下你對(duì)于圓鋼的外形有了一定的了解了吧，那就讓我們在深入的了解一下我們生活中所使用的普通圓鋼。 </p> <p> 為什么被稱為圓鋼，當(dāng)然是因?yàn)樗兄鴪A形的橫截面，因此有圓鋼之稱，一般來說，圓鋼的橫截面直徑會(huì)有不同，根據(jù)直徑的不同圓鋼分為不同的規(guī)格，并且在包裝時(shí)都是數(shù)根圓鋼包裹在一起的，不小心看上去會(huì)以為圓鋼很粗，實(shí)際上并沒有想象中的那樣。 </p> <p> 用于制作圓鋼的材料很多，比如Q235、Q195、10#、20#等等，并且圓鋼的制作工藝也分為冷拉、熱軋、鍛制這三種。其中圓鋼大部分使用的是熱軋工藝，**小的規(guī)格為5.5毫米，比較大的規(guī)格能夠達(dá)到250毫米。一些螺栓，鋼筋，大型機(jī)械的零件都是使用圓鋼制作的，其用途還是比較很多的。鍍鋅圓鋼采購，云南貿(mào)軒商貿(mào)有限公司。昆明質(zhì)量鍍鋅圓鋼報(bào)價(jià)</p><p
