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(wú)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 /> 鍍鋅圓管如何刷漆？要注意什么？昆明五華區(qū)114鍍鋅圓管價(jià)格咨詢</p><p
