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。封頭蝶板的運(yùn)動(dòng)帶有擦拭性，故大多數(shù)的封頭可用于帶懸浮固體顆粒的介質(zhì)。江蘇吸收塔封頭報(bào)價(jià)</p><p
