提高冷軋精密無縫鋼管機(jī)產(chǎn)量的第三個途徑是，必須提高軋管機(jī)的有效工作系數(shù)，值。要提高9，將涉及多方面的問題.一方面，要求軋管機(jī)的設(shè)計要合理，加工制造精度高，以減少維護(hù)及檢修停機(jī)時間。另一方面要提高軋管的機(jī)械化、‘自動化水平，以減少輔助操作時間。第三方面，也是很重要的發(fā)展方向，要實現(xiàn)冷軋管機(jī)不停機(jī)，連續(xù)裝科和連續(xù)軋制.提高軋管機(jī)產(chǎn)量的第四個措施是增加同時軋制管材的根數(shù)。需要指出的是，線數(shù)增加并不能使軋管機(jī)的產(chǎn)量成整數(shù)倍增加，而且成品管的精度將有所降低‘對于中間工序，是完全可以的?，F(xiàn)在的精密鋼管能夠被廣泛投入到流體管道中使用，其內(nèi)壁光滑，同時也具有一定的抗腐蝕性，在安裝的過程中也具有一定的優(yōu)勢，在安裝的過程中只需要焊接機(jī)可，可以省去檢查其氣密性的步驟，同時也可以減少對精密鋼管護(hù)理的不必要開支。

class="khcont">精密鋼管生產(chǎn)工藝特點：精密鋼管的生產(chǎn)工序，與用其它方式生產(chǎn)的大直徑鋼管的生產(chǎn)工序相比，有如下特點：原料準(zhǔn)備工序簡單;原料上機(jī)后，管坯用一道工序就可做成;不需要矯直工序。精密無縫鋼管機(jī)的生產(chǎn)效率一直是人們?yōu)殛P(guān)注的問題。提高冷軋管機(jī)的生產(chǎn)效率就是提高冷軋精密無縫鋼管機(jī)的小時產(chǎn)量產(chǎn)量A、一般用下式進(jìn)行計算冷軋管機(jī)的小時.從上式可知，提高軋厚壁無縫管機(jī)產(chǎn)量的個重要途徑就是提高軋管機(jī)的速度。要想提高軋管速度，必須首先解決軋管機(jī)機(jī)架的慣性力和慣性扭矩的平衡方法及具體結(jié)構(gòu)，各個零部件的強(qiáng)度和剛度以及潤滑、冷卻、使用壽命等問題。加大送進(jìn)量，和提高延伸率人是提高軋管機(jī)產(chǎn)量的又一有效的措施。為此，采用環(huán)形孔型塊是理想的解決方法，它既有利于加長機(jī)架行程又不過多地增加軋輥的直徑。</div><p><img

若欲獲得尺寸更小和質(zhì)量更好的無縫管，必須采用冷軋、冷拔或者兩者聯(lián)合的方法。冷軋通常在二輥式軋機(jī)上進(jìn)行，鋼管在變斷面圓孔槽和不動的錐形頂頭所組成的環(huán)形孔型中軋制。冷拔通常在0.5～100T的單鏈?zhǔn)交螂p鏈?zhǔn)嚼浒螜C(jī)上進(jìn)行。擠壓法即將加熱好的管坯放在密閉的擠壓圓筒內(nèi)，穿孔棒與擠壓桿一起運動，使擠壓件從較小的模孔中擠出。此法可生產(chǎn)直徑較小的鋼管。精密管的焊接工藝。工藝：精密管中的Cr、Mo、V等強(qiáng)烈的碳化物形成元素有使接頭過熱區(qū)產(chǎn)生再熱裂紋的傾向。坡口機(jī)加工后(焊接前)MT檢查，無裂紋、無缺陷，焊前坡口及周圍表面清理(油污、除銹等)至見金屬光澤;坡口裝配避免強(qiáng)制組對。焊接前整體或局部預(yù)熱，焊縫兩邊各150mm范圍內(nèi)保證預(yù)熱溫度250～300度;層間溫度應(yīng)在預(yù)熱溫度控制范圍內(nèi)。

GTAW(純Ar氣體保護(hù))：建議采用TIG-R31(含V)焊絲，直徑2.5mm，電流100～140A。如果有一定壁厚，管徑不是很小的話，建議采取GTAW+SMAW。SMAW：焊條采用R337，規(guī)格可以按實際情況來定。焊接完成后清理飛濺，加熱至350～450℃，保溫并緩冷的后熱措施。12Cr1MoV采用相應(yīng)成分的耐熱鋼焊條，如R310、R312、R317、R316Fe，焊前預(yù)熱250～350℃，焊后回火處理710～750℃。焊補(bǔ)缺陷或焊后不能進(jìn)行熱處理時，也可采用奧氏體鋼焊條，如A302、A307。這時，由于焊縫與母材膨脹系數(shù)不同，同時在長期高溫工作時還可發(fā)生碳的擴(kuò)散遷移現(xiàn)象，而易于導(dǎo)致在融合區(qū)發(fā)生破壞。將精密鋼管送入精密鋼管機(jī)組，經(jīng)多道軋輥滾壓，精密鋼管逐漸卷起，形成有開口間隙的圓形精密鋼管，調(diào)整擠壓輥的壓下量，使精密鋼管間隙控制在1~3mm，并使焊口兩端齊平。如間隙過大，則造成鄰近效應(yīng)減少，渦流熱量不足，精密鋼管晶間接合不良而產(chǎn)生未熔合或開裂。如間隙過小則造成鄰近效應(yīng)增大，精密鋼管熱量過大，造成精密鋼管燒損;或者精密鋼管經(jīng)擠壓、滾壓后形成深坑，影響精密鋼管表面質(zhì)量。
