310s不銹鋼板對性能的各種影響

 

310s不銹鋼板的抗拉強度為615.6 MPa、310s不銹鋼板帶夾層不銹鋼復合板異步熱軋過程中的翹曲問題,采用MSC. Marc有限元軟件樹立了帶夾層不銹鋼復合板三維熱力耦合模型,310s不銹鋼板剖析了厚度比、輥速比、首道次壓下率以及軋件與上下軋輥間摩擦系數比對復合軋制過程中翹曲變形、塑性應變以及軋制力的影響規律。結果標明,310s不銹鋼板厚度比增加使x向塑性應變值以及軋制力增大,加劇復合板的翹曲變形;310s不銹鋼板首道次壓下率對復合板的翹曲變形影響較小;輥速比對復合板的x向塑性應變影響較大,隨著輥速比的增加,翹曲曲率呈現先減小后增大的現象,與軋制力變化趨向相反,在輥速比為1. 15時310s不銹鋼板為平直;軋件與上下軋輥間摩擦系數比的合理選擇亦可對復合板的翹曲現象產生一定的抑止作用。310s不銹鋼板橋梁支座用球面不銹鋼板成形技術中止研討,剖析了球面不銹鋼板的構造特征及成形工藝,研討了拉深、310s不銹鋼板脹形復合成形過程中起皺和拉裂的均衡控制規律;剖析了拉深系數等影響成形的關鍵工藝參數,設
