style="text-indent:25px">鈦板不銹鋼封頭屬于不銹鋼封頭的一種，主要是用來(lái)對(duì)不銹鋼管道進(jìn)行密封的零件。在它制造的過(guò)程中，有一個(gè)工藝程序是需要謹(jǐn)慎再謹(jǐn)慎的，那是熱處理工藝。在對(duì)鈦板不銹鋼封頭進(jìn)行熱處理的過(guò)程中是很容易出現(xiàn)熱應(yīng)力的，原因是加熱和冷卻的過(guò)程中，表層和心部的冷卻速度和時(shí)間的不一致，有溫差存在。另外還比較容易出現(xiàn)組織應(yīng)力，主要是由于組織的變化即奧氏體向馬氏體轉(zhuǎn)變時(shí)，因比容的增大會(huì)伴隨工件體積的膨脹，工件各部位先后相變，造成體積長(zhǎng)大不一致。</p><p style="text-indent:25px">在封頭的邊緣處就會(huì)產(chǎn)生一定的彎曲應(yīng)力和薄膜應(yīng)力，也就是我們所說(shuō)的邊緣應(yīng)力。所以為了避免邊緣應(yīng)力與焊接應(yīng)力相重合，通常均帶有直邊段。而半球形結(jié)構(gòu)設(shè)計(jì)通常不采用直邊，這是為什么呢？要知道，在這樣的產(chǎn)品中，內(nèi)壓作用下其應(yīng)力狀況與球殼是一樣的。由于與球冠公式是按球冠與相連接的圓筒體等厚導(dǎo)出的，因此要求相連接的圓筒不小于球冠厚度。此外還有不少用戶比較疑惑，相比較來(lái)說(shuō)，其中半球形結(jié)構(gòu)的封頭產(chǎn)品受力效果好，那么為什么一般的中、低壓容器很少使用。被調(diào)介質(zhì)為粘性流體或含有固體懸浮物時(shí)，用封頭可以克服介質(zhì)對(duì)閥桿移動(dòng)的阻力。</p><div
