【導(dǎo)讀】奧氏體相變動力學(xué)。采用二維有限元分析來求解，采用非均勻邊界條件的熱傳導(dǎo)。方程，因為這樣是符合實際冷卻條件的。采用熱力學(xué)分析和累進(jìn)法則獲得了冷卻。曲線，并對奧氏體轉(zhuǎn)變行為進(jìn)行分析。為了驗證模型結(jié)果，在實驗室測量不同冷。預(yù)測數(shù)據(jù)和實驗結(jié)果較為吻合。鍵，直接影響最終產(chǎn)品的組織與性能。在熱軋鋼材中，當(dāng)鋼材離開最后一架軋機(jī)。時一般為奧氏體組織，鋼在軌道上冷卻時，熱軋產(chǎn)品發(fā)生奧氏體連續(xù)轉(zhuǎn)變。此前一些已經(jīng)發(fā)表的文章研究了上述冷卻條件下鋼材的換。Sun等[5]已經(jīng)開發(fā)出一種基于有限元方法的數(shù)學(xué)模型來描述運(yùn)。行軌道上帶鋼的耦合熱冶金行為。Zhou等[7]已使用有限元程序ABAQUS用于確定熱。軋帶鋼軋制過程中在控冷輥道上的溫度分布和殘余應(yīng)力。對流換熱是主要的傳熱方式。被認(rèn)為是一個隨溫度變化的因素，然而在溫度600℃可。忽略不計輻射效應(yīng)，對流換熱是表面邊界的主要熱傳輸機(jī)制。應(yīng)當(dāng)指出，在冷卻階段特別是早期的奧氏體開始分解之
