摘 要: 根據(jù)某高爐使用的鑲磚銅冷卻壁建立了全尺寸三維模型。 以有限元為手段， 采用熱、 結(jié)構(gòu)耦合的方法計算了高溫狀態(tài)下銅冷卻壁的應(yīng)力和應(yīng)變，計算結(jié)果與熱態(tài)實測數(shù)據(jù)基本吻合。 計算結(jié)果表明： 銅冷卻壁在高爐爐況下的基體溫度以及由此產(chǎn)生的熱應(yīng)力都不足以使其很快產(chǎn)生裂紋。 通過計算比較得出， 銅冷卻壁在高爐中的熱變形趨勢不僅與其溫度分布有關(guān)，也與安裝冷卻壁的方式和定位銷位置有關(guān)， 計算結(jié)果為高爐銅冷卻壁的安裝設(shè)計提供了依據(jù)。

Abstract: Full-size three-dimensional model was established according to copper stave with insert in a certain BF. Based on the finite element analysis, the stress and strain of the copper stave under a high temperature were calculated with the methods of thermo-structure coupling and the results are almost identical with actual measured data. The results indicate that neither temperature nor heat stress of copper stave under a BF operating condition are the stress formed sufficient to cause crack quickly. Comparison of the calculation values show that the trend of thermal distortion of the copper stave used in BF can be affected by temperature distribution, installation manner and the location of bolt. All these provide a basis for the design and installation of copper stave.
