style="text-indent:25px">不銹鋼封頭冷加工出現(xiàn)磁性的具體原因。其實(shí)，當(dāng)處于亞穩(wěn)定狀態(tài)的奧氏體不銹鋼進(jìn)行冷加工的時候，其中有一部分的奧氏體會發(fā)生馬氏體轉(zhuǎn)變，同時還會和原來的奧氏體保持共格。在實(shí)際工作中，我們通常會把這種以切變方式在極短時間內(nèi)發(fā)生的無擴(kuò)散相變，稱作致生馬氏體相變或者是形變誘導(dǎo)馬氏體相變。說到這里，我們就需要對不銹鋼封頭產(chǎn)品所采用材料的結(jié)構(gòu)來進(jìn)行進(jìn)一步說明。事實(shí)上，不銹鋼中馬氏體通常會包括兩種結(jié)構(gòu)形式，一種是有體心立方結(jié)構(gòu)的α’馬氏休，另一種是密集六方結(jié)構(gòu)的ε馬氏體。也就是說，如果在加工不銹鋼封頭的時候，所采用的材料結(jié)構(gòu)不同的話，那么就可能會發(fā)生不同的情況。在這兩種不同形態(tài)中，其中第1種結(jié)構(gòu)的材料具有一定的磁性，而第二種結(jié)構(gòu)的材料不具有磁性。但是，如果鎳鉻含量較高的話，也會產(chǎn)生ε馬氏體。因此，我們就會明白，當(dāng)不銹鋼封頭的部分組織在進(jìn)行轉(zhuǎn)換的過程中，就會產(chǎn)生一定的磁性。通常情況下，奧氏體的穩(wěn)定性主要取決于其自身的化學(xué)成分。如果想要避免有磁性產(chǎn)生的話，應(yīng)當(dāng)更換材料，或者是進(jìn)行固溶處理。</p><p style="text-indent:25px">從受力和制造兩方面比較半球形、橢圓形、碟形、錐殼和平蓋封頭的特點(diǎn)，并說明其主要應(yīng)用場合。(1)半球形封頭：在均勻內(nèi)壓作用下，薄壁球形容器的薄膜應(yīng)力為相同直徑圓筒體的一半。但缺點(diǎn)是深度大，直徑小時，整體沖壓困難，大直徑采用分瓣沖壓其拼焊工作量也較大。半球形封頭常用在高壓容器上。(2)橢圓形封頭：橢球部分經(jīng)線曲率變化平滑連續(xù)，故應(yīng)力分布比較均勻，且橢圓形封頭深度較半球形封頭小得多，易于沖壓成型，是目前中、低壓容器中應(yīng)用較多的封頭之一。(3)碟形封頭：是一不連續(xù)曲面，在經(jīng)線曲率半徑突變的兩個曲面連接處，由于曲率的較大變化而存在著較大邊緣彎曲應(yīng)力。該邊緣彎曲應(yīng)力與薄膜應(yīng)力疊加，使該部位的應(yīng)力遠(yuǎn)遠(yuǎn)高于其它部位，故受力狀況不佳。但過渡環(huán)殼的存在降低了封頭的深度，方便了成型加工，且壓制碟形封頭的鋼模加工簡單，使碟形封頭的應(yīng)用范圍較為普遍。(4)錐殼：結(jié)構(gòu)不連續(xù)，錐殼的應(yīng)力分布并不理想，但其特殊的結(jié)構(gòu)形式有利于固體顆粒和懸浮或粘稠液體的排放，可作為不同直徑圓筒體的中間過渡段，因而在中、低壓容器中使用較為普遍。小封頭，在制造時整體成型，而大、中型封頭需要先拼接后成型。</p><div

style="text-indent:25px">越大型號的封頭使用過程中會相對的問題較多，我們來看看封頭的使用要注意一些什么?1、封頭的形狀：根據(jù)設(shè)備的需求與合理，選擇合適的封頭種類：如橢圓形、蝶形、錐形、球形等；2、封頭的尺寸：是指的內(nèi)徑還是外徑。如377、426是以外徑為準(zhǔn)；350、400、450是以內(nèi)徑為準(zhǔn)；3、封頭的高度：一般封頭的高度我們都是按照國家標(biāo)準(zhǔn)來生產(chǎn)，但是也有客戶的產(chǎn)品設(shè)計不一樣，需要的封頭高度不同，所以有特殊要求定貨雙方要協(xié)商一致；4、封頭的材質(zhì)：一般使用較多的是304不銹鋼和碳鋼兩種，但是也有特殊用途的，如耐高溫必須用310S材質(zhì)、耐酸性一定要使用316L材質(zhì)等；5、封頭的周長：封頭是用模具沖壓成形，鋼板在沖壓過種中會有一些應(yīng)力存在，而且沖壓拉伸過程中會有相對變形，那么封頭的直徑要如何判斷準(zhǔn)確與否，就看周長多少，是否標(biāo)準(zhǔn)；6、封頭與筒體焊接：封頭與筒體對焊的時候，一定是先將封頭與筒體用幾個點(diǎn)平均固定，再均勻的進(jìn)行焊接處理。封頭與盲板的作用差不多,在施工中要因工程的需要而定。蘇州提取設(shè)備封頭廠商</p><p
