style="text-indent:25px">封頭拋光時(shí)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(jìn)行堵塞，而對(duì)于封頭來說，為了讓其與安裝的部件相一致，所以有時(shí)會(huì)需要做一些拋光處理。在拋光時(shí)對(duì)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(jìn)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(huì)用專門的拋光機(jī)，這些拋光機(jī)的自動(dòng)化設(shè)計(jì)非常高，在進(jìn)行工作的時(shí)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(tái)上作固定處理，就可以開始進(jìn)行拋光了。當(dāng)然拋光的時(shí)間需要做下合理的設(shè)定，這樣工作就會(huì)變得更簡(jiǎn)單。需要注意的是，封頭拋光分為精拋和細(xì)拋兩種方式，做粗拋處理的封頭可以所表層的損傷及時(shí)去除，拋光速率會(huì)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(diǎn)，能適用在各個(gè)地方，并且使用年限長(zhǎng)，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(jī)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。浙江儲(chǔ)氣罐封頭廠家封頭的尺寸大小不同，使封頭所用的原料多少也會(huì)有所不同，所以封頭的價(jià)格會(huì)隨著尺寸的增大而增加。</p><div
