style="text-indent:25px">封頭拋光時有哪些要求？在鍋爐和一些壓力容器上，為了保證工作的密封性，通常需要封頭進行堵塞，而對于封頭來說，為了讓其與安裝的部件相一致，所以有時會需要做一些拋光處理。在拋光時對封頭的形狀也是有要求的，如不銹鋼橢圓形封頭、蝶形封頭、錐形封頭等可進行內(nèi)外拋光，效果非常好。那么封頭拋光的要求有哪些呢，下面就一起來了解下。封頭拋光通常會用專門的拋光機，這些拋光機的自動化設(shè)計非常高，在進行工作的時候，只要把拋光的工件等放在相應(yīng)的位置上，然后在工作臺上作固定處理，就可以開始進行拋光了。當然拋光的時間需要做下合理的設(shè)定，這樣工作就會變得更簡單。需要注意的是，封頭拋光分為精拋和細拋兩種方式，做粗拋處理的封頭可以所表層的損傷及時去除，拋光速率會比較高；而使用精拋技術(shù)的封頭，不僅能去掉封頭表層的損傷，還能讓拋光損傷減少到較低。它具有以往的材料都不具有的優(yōu)點，能適用在各個地方，并且使用年限長，質(zhì)量過硬，不存在維修問題。封頭功能越來越多樣化，使得它的發(fā)展也是越來越壯大，在各大機械行業(yè)中頻繁使用到的封口材料。它的功能得到了比較大的提升，在抗壓能力上它的性能優(yōu)良比較大程度的改變，密封性也比原來更加優(yōu)良。鋁制橢圓封頭與其他普通的封頭相比，耐腐蝕性更強，導(dǎo)熱性能好，材質(zhì)輕盈，方便使用。</p><div

style="text-indent:25px">封頭毛坯是如何制作的？1.封頭毛坯尺寸(計算公式)：P=1.2(PN+δ+2h)。2.劃下料線時,先劃十字中心線,再劃坯料線及人孔開孔線,人孔之長短軸要與十字中心線重合且長軸必須與鋼板軋制方向垂直(軋制方向通常為鋼板長度方向)。3.下料時,封頭毛坯外圓可用手工切割，易采用定心切割,推薦采用仿形切割。4.封頭毛坯的拼接：封頭毛坯應(yīng)盡量采用整塊鋼板制成。若需拼接時,允許由兩塊鋼板按GB/T25198-2010標準和GB/T25198-2010標準、施工圖樣進行。焊接后，內(nèi)表面拼接焊縫以及影響成形質(zhì)量的外表面拼接焊縫,在成形前應(yīng)將焊縫余高打磨至與母材齊平,鏟平長度為離圓坯外邊緣300～350mm。5.當壓制有孔封頭時，中間開的小孔應(yīng)光滑平整，鋸齒形的氣割邊緣應(yīng)修磨光滑，以免壓孔翻邊時出現(xiàn)開裂現(xiàn)象。6.毛坯必須按〈規(guī)定〉進行材質(zhì)標記移植,標記必須清晰正確。加熱爐周圍的障礙物必須清理,加熱爐內(nèi)的雜物應(yīng)清理,裝爐前,應(yīng)把坯料上的雜物清理干凈。檢查送料工具,保證運轉(zhuǎn)正常，安全裝爐。橢圓形的封頭的深度比半球形的封頭淺的多，較易制造。南通干混砂漿運輸車封頭制造廠</p><p
