平常的熱鍍鋅圓管都是軋制截面,鑒于出產(chǎn)工藝差,翼緣內(nèi)邊有1:10坡度.工字鋼的軋制不同于平常工字鋼*用一套水平軋輥,鑒于其翼緣較寬且無斜度,故須增設(shè)一組立式軋輥同時(shí)正在輥軋。所以,其軋制工藝和設(shè)置都比平常軋機(jī)繁復(fù).中國(guó)可出產(chǎn)的較大軋制H型鋼高度為800mm,大于了只能是焊接組合截面. </p> <p> 2.人的因素是熱鍍鋅圓管施焊的控制要點(diǎn)。由于缺乏必要的焊后控制手段，易偷工減料，影響質(zhì)量；同時(shí)鍍鋅管的焊接特殊性使得不容易確保焊接質(zhì)量。 </p> <p> <br /> 昆明五華區(qū)6米鍍鋅圓管價(jià)格查詢鍍鋅圓管廠家現(xiàn)貨供應(yīng)，云南贛僑貿(mào)易供應(yīng)。</p><div

鍍鋅鋼管的鋅鍍層的使用溫度不得超過2500C,在此溫度上鋅結(jié)晶組織變形，發(fā)脆，耐蝕性下降。有耐蝕，耐熱要求的零件宜用Zn-Ni合金層。鍍鋅電解液可分為堿性和弱酸性兩大類，國(guó)內(nèi)外常用的有無氰鋅酸鹽鍍鋅，**鍍鋅，銨鹽鍍鋅，氯化物鍍鋅，硫酸鹽鍍鋅等。就國(guó)內(nèi)而言，無氰鋅酸鹽鍍鋅仍是主流。近年來由于鍍鋅添加劑的性能的改進(jìn)提高，氯化物鍍鋅和低氰光亮鍍鋅發(fā)展較快，而銨鹽鍍鋅在繼續(xù)下降。 </p> <p> 選擇鍍液要根據(jù)鍍件材質(zhì)，形狀，外觀要求而定，如沖壓小件和復(fù)雜件，特別是需要輔**極的深孔或管狀件宜選用堿性鍍液﹔對(duì)氫脆敏感的零件宜用弱酸性鍍鋅液。當(dāng)采用兩種性能不同的鍍液時(shí)，對(duì)鍍鋅鋼管生產(chǎn)十分有利。 </p> <p> <br /> </p><p> 鍍鋅圓管應(yīng)該達(dá)到的技術(shù)要求 </p> <p> 1、牌號(hào)和化學(xué)成分 </p> <p> 鍍鋅鋼管用鋼的牌號(hào)和化學(xué)成分應(yīng)符合GB3092所規(guī)定的黑管用鋼的牌號(hào)和化學(xué)成分。 </p> <p> 2、制造方法 </p> <p> 黑管的制造方法（爐焊或電焊）由制造廠選擇。鍍鋅采用熱浸鍍鋅法。 </p> <p> 3、螺紋及管接頭 </p> <p> 3.1帶螺紋交貨的鍍鋅鋼管，螺紋應(yīng)在鍍鋅后車制。螺紋應(yīng)符合YB822的規(guī)定。 </p> <p> 3.2鋼制管接頭應(yīng)符合YB238的規(guī)定；可鍛鑄鐵管接頭應(yīng)符合YB230的規(guī)定。 </p> <p> 4、力學(xué)性能鋼管鍍鋅前的力學(xué)性能應(yīng)符合GB3092的規(guī)定。 </p> <p> 5、鍍鋅層的均勻性鍍鋅鋼管應(yīng)作鍍鋅層均勻性的試驗(yàn)。鋼管試樣在硫酸銅溶液中連續(xù)浸漬5次不得變紅（鍍銅色）。 </p> <p> 6、冷彎曲試驗(yàn)公稱口徑不大于50mm的鍍鋅鋼管應(yīng)作冷彎曲試驗(yàn)。彎曲角度為90°，彎曲半徑為外徑的8倍。試驗(yàn)時(shí)不帶填充物，試樣焊縫處應(yīng)置于彎曲方向的外側(cè)或上部。試驗(yàn)后，試樣上不應(yīng)有裂縫及鋅層剝落同象。 </p> <p> 7、水壓試驗(yàn)水壓試驗(yàn)應(yīng)在黑管進(jìn)行，也可用渦流探傷代替水壓試驗(yàn)。試驗(yàn)壓力或渦流探傷對(duì)比試樣尺寸應(yīng)符合GB3092的規(guī)定。 </p> <p> <br /> 鍍鋅圓管采用硫酸鹽電鍍鋅鐵合金工藝，即生產(chǎn)線槽和槽全部穿孔直通，無任何溶液流出或溢出。</p><div

2、因?yàn)殇\鍍層具備杰出的延展性，因此可進(jìn)行冷沖、軋制、折彎等各種成型而不破壞鍍層。 </p> <p> 3、鋼結(jié)構(gòu)件熱鍍鋅后，相當(dāng)于一次退火處理，能有效改進(jìn)鋼基體的機(jī)械功能，消除鋼件成型焊接時(shí)的應(yīng)力，有助于對(duì)鋼結(jié)構(gòu)件進(jìn)行車削加工。 </p> <p> 4、具備比較厚的致密的純鋅層掩蓋在鋼鐵表面上，它能夠避免鋼鐵基體與任何的腐蝕溶液的觸摸，維護(hù)鋼基體免遭腐蝕。 </p> <p> 5、鋅鍍層經(jīng)鉻酸鈍化后形成白色、五顏六色、軍綠色等，漂亮大方，具備必定的裝飾性； </p> <p> 6、熱鍍鋅后的件表面亮光美觀漂亮。 </p> <p>

style="text-indent:25px">***鍍鋅圓管廠家，云南贛僑貿(mào)易供應(yīng)。盤龍區(qū)國(guó)標(biāo)鍍鋅圓管價(jià)格咨詢</p>鍍鋅圓管廠家在鍍鋅前需處理什么？ <p> 其實(shí)鍍鋅圓管的分類并不復(fù)雜，只有熱鍍鋅和電鍍鋅兩種。熱鍍鋅有濕法、干法、鉛鋅法、氧化還原法等，不同熱鍍鋅方法的主要區(qū)別在鋼管酸浸清洗后，用什么方法活化管體表面提高鍍鋅質(zhì)量，現(xiàn)生產(chǎn)中主要采用干法和氧化還原法。電鍍鋅在技術(shù)上有一定的復(fù)雜性，但對(duì)單面鍍層，內(nèi)外表面鍍層厚度不同的雙面鍍層，以及薄壁管鍍鋅等皆須采用此法。 </p> <p> 鋼管應(yīng)在鍍鋅前進(jìn)行處理：即酸洗、清洗、洗滌、浸涂溶劑、干燥。酸洗時(shí)間一般為30-60分鐘；酸洗后，用吊車將鋼管吊至清洗槽進(jìn)行清洗；水滴干燥后，將鋼管吊至溶劑罐中浸泡約一分鐘；為了提高鋼管溶劑中預(yù)鍍的效果，溶劑始終保持弱堿性，然后用吊車吊至干燥爐平臺(tái)，在干燥爐中干燥。干燥溫度為100-130℃，時(shí)間一般為6-10分鐘。<span style="display:none;"></span> </p> <p> 鋼管進(jìn)行鍍鋅處理，目的是提高鋼管的防腐性能，鋅是用來防銹的，但是是鋅本身也氧化，只是氧化的速度比鐵慢，如果當(dāng)鋼管鍍鋅完畢以后再進(jìn)行防腐處理后的耐久度會(huì)更長(zhǎng)。鍍鋅鋼管防腐處理外壁工藝主要有環(huán)氧煤瀝青防腐、3PE防腐、環(huán)氧樹脂防腐等，內(nèi)壁防腐工藝有IPN8710、水泥砂漿等工藝。盤龍區(qū)國(guó)標(biāo)鍍鋅圓管價(jià)格咨詢</p><p
