style="text-indent:25px">不銹鋼封頭的熱處理：一方面鋼在熱處理過(guò)程中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)大不一致而產(chǎn)生組織應(yīng)力。不銹鋼封頭組織應(yīng)力變化的較終結(jié)果是表層受拉應(yīng)力，心部受壓應(yīng)力，恰好與熱應(yīng)力相反。組織應(yīng)力的大小與工件在馬氏體相變區(qū)的冷卻速度，形狀，材料的化學(xué)成分等因素有關(guān)。只不過(guò)熱應(yīng)力在組織轉(zhuǎn)變以前就已經(jīng)產(chǎn)生了不銹鋼封頭，江蘇提取設(shè)備封頭廠家，而組織應(yīng)力則是在組織轉(zhuǎn)變過(guò)程中產(chǎn)生的，在整個(gè)冷卻過(guò)程中，熱應(yīng)力與組織應(yīng)力綜合作用的結(jié)果，就是工件中實(shí)際存在的應(yīng)力。這兩種應(yīng)力綜合作用的結(jié)果是十分復(fù)雜的，受著許多因素的影響，如成分、形狀、熱處理工藝等。就其發(fā)展過(guò)程來(lái)說(shuō)只有兩種類型，即熱應(yīng)力和組織應(yīng)力，作用方向相反時(shí)二者抵消，作用方向相同時(shí)二者相互迭加。不管是相互抵消還是相互迭加，兩個(gè)應(yīng)力應(yīng)有一個(gè)占主導(dǎo)因素，熱應(yīng)力占主導(dǎo)地位時(shí)的作用結(jié)果是工件心部受拉，表面受壓，江蘇提取設(shè)備封頭廠家，江蘇提取設(shè)備封頭廠家。組織應(yīng)力占主導(dǎo)地位時(shí)的作用結(jié)果是工件心部受壓表面受拉。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)。江蘇提取設(shè)備封頭廠家</p><div
