href="http://www.klxtx.com">直縫焊管生產(chǎn)線</a>上料操作規(guī)程：上料工首先確認(rèn)帶鋼是否符合生產(chǎn)規(guī)格的要求，用卡尺及千分尺檢查鋼帶壁厚，用盒尺測量寬度以及目測外觀質(zhì)量。用天車吊起鋼卷，平套于轉(zhuǎn)盤軸上撬起帶鋼頭時必須先用卡具卡緊外圈阻止鋼帶松開傷人，取下卡具，將帶鋼頭用壓切剪剪齊，送進對焊機架。</span></div> <div> <span style="font-size:22px;"><a href="http://www.klxtx.com">直縫焊管生產(chǎn)線</a>在對焊的過程介紹：同上料工配合，把剪切的鋼帶頭尾對齊，操縱夾緊機氣閥，壓緊鋼帶焊接，焊接時要帶好面罩，穿好工作服，手套和腳罩，阻止孤光灼傷眼睛或皮膚，并做好措施。啟動夾緊氣閥清除焊瘤，焊渣。</span></div> <div> <span style="font-size:22px;"><a href="http://www.klxtx.com">直縫焊管生產(chǎn)線</a>的儲料:啟動引料開關(guān)，把鋼帶送進活套或儲料箱進行儲料，引料時集中精力操作，如有故障及時與上料工和主控臺聯(lián)系，停車檢查。當(dāng)鋼帶在活套內(nèi)卡死，翻料時，應(yīng)及時停車，不能在運行中敲擊。</span></div> <div> <span style="font-size:22px;">直縫焊管生產(chǎn)線佩戴的軋輥調(diào)整：調(diào)整軋輥時應(yīng)找正成形輥，擠壓輥，定徑輥軋制中心線，調(diào)整立棍標(biāo)高和水平輥壓下量，調(diào)整后軋輥孔型中心與軋制中心線的偏差應(yīng)小于0.5mm，上下孔型中心偏差小于0.1mm配套立棍高低偏差應(yīng)小于0.1mm，水平上棍兩側(cè)壓下量應(yīng)一致，上下軋輥的徑向跳動和軸向竄動量應(yīng)下雨0.5mm。</span></div> <div> <span style="font-size:22px;">鋼帶進入成型機組后低俗運行，應(yīng)逐架次調(diào)整，有末架次出來的管筒尺寸必須滿足焊接要求，出定徑機組的管體不得扭轉(zhuǎn)，管徑應(yīng)符合標(biāo)準(zhǔn)要求，管體無劃傷，調(diào)整試車時不允許人停留在機架上。</span></div> <div> <span style="font-size:22px;">直縫焊管生產(chǎn)線在生產(chǎn)中禁止在成型機內(nèi)，冷卻槽內(nèi)，定徑機內(nèi)用手檢測焊縫，以免擠到手指，注意檢查鋼管是否在磚縫，搭焊，鼓包，壓痕等。如發(fā)現(xiàn)缺陷及時停車調(diào)整，消除缺陷。</span></div> <div> </div> <div id="tx3ppb3"
