style="text-indent:25px">不銹鋼封頭冷卻速度愈快,含碳量和合金成分愈高,冷卻過程中在熱應(yīng)力作用下產(chǎn)生的不均勻塑性變形愈大,末尾形成的殘余應(yīng)力就愈大。不銹鋼封頭在加熱和冷卻過程中,表層和心部的冷卻速度和時間的不一致,形成溫差，導(dǎo)致體積膨脹和收縮不均而產(chǎn)生應(yīng)力,即熱應(yīng)力。不銹鋼封頭在熱應(yīng)力的作用下,由于表層開始溫度低于心部,收縮也大于心部而使心部受拉,當(dāng)冷卻結(jié)束時，由于心部末尾冷卻體積收縮不能自由進(jìn)行而使表層受壓心部受拉。即在熱應(yīng)力的作用下較終使工件表層受壓而心部受拉。這種現(xiàn)象受到冷卻速度,材料成分和熱處理工藝等因素的影響。鋼在熱處理過程中由于組織的變化即奧氏體向馬氏體轉(zhuǎn)變時,因比容的增大會伴隨工件體積的膨脹,工件各部位先后相變，造成體積長大不一致而產(chǎn)生組織應(yīng)力。</p><p style="text-indent:25px">封頭為了保證加工材料的質(zhì)量，一定要加強對材料的檢驗工作，從而確保它能完全溶固。這樣對橢圓不銹鋼封頭封頭固溶的處理了可以增強它的恢復(fù)力，從而提高橢圓封頭的焊接質(zhì)量。其實焊接工藝也會影響到封頭的性能，所以要選擇合適的焊接工藝，使得封頭的接頭性能受到的影響會盡量小一點。不銹鋼封頭使用前需要進(jìn)行表面處理，比如說在滲氮前用細(xì)砂在0.15~0.25MPa的壓力下進(jìn)行噴砂處理，直至表面呈暗灰色，去除表面灰塵后立即進(jìn)爐。滲氮前需對不銹鋼封頭進(jìn)行磷化處理。未經(jīng)加熱，封頭成形后表面維持原有材料的光潔表面，外觀漂亮。</p><div
