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)展速度非常快，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。昆明質(zhì)量鍍鋅圓鋼現(xiàn)貨鍍鋅圓鋼廠家，云南貿(mào)軒商貿(mào)有限公司。</p><div

</p> <p> 在一般的環(huán)境里，鍍鋅圓鋼的熱鍍鋅防銹厚度可保持50年以上而不必修補；在市區(qū)或近海區(qū)域，熱鍍鋅防銹層則可保持20年而不必修補。 </p> <p> 鍍鋅圓鋼的鍍鋅層與鋼材間是冶金結(jié)合，成為鋼表面的一部份，因此鍍鋅圓鋼的鍍層的持久性較為可靠；鍍層的韌性強，鍍鋅層形成一種特別的冶金結(jié)構(gòu)，鍍鋅圓鋼的這種工藝，能較強的承受在運送及使用時受到的機械損傷；因此我公司的鍍鋅圓鋼受到全國各地廣大用戶的一致好評，歡迎新老客戶來人來電訂購我公司的鍍鋅圓鋼. </p><p> 鍍鋅圓鋼與鋼管的區(qū)別 </p> <p> <br /> </p> <p> 強度不一樣，圓鋼強度低，其它鋼強度高，即直徑大小相同的圓鋼與其它鋼筋相比，圓鋼所能承受的拉力要比其它鋼筋小，但圓鋼的塑性比其它鋼筋強，即圓鋼在被拉斷前有較大的變形,而其它鋼筋在被拉斷前的變形要小得多。本公司常年銷售和配送：天津無縫鋼管廠,成都攀鋼、包鋼、冶鋼、寶鋼、鞍鋼等幾大鋼廠的無縫管,合金管.備有現(xiàn)貨3000余噸.我公司主要經(jīng)營各鋼廠生產(chǎn)的材質(zhì)為10#、20#、35#、45#、Q345、27SiMn、40cr，地質(zhì)管，石油套管<J55、K55、N80、P110>，技術(shù)標(biāo)準：高壓鍋爐管GB5310-2008，化肥**管GB6479-2000，石油裂化管GB9948-2000,低中壓鍋爐管GB3087-2008
