以首钢京唐实际生产过程中倒角结晶器的铜板尺寸、水道布置、铜板实测温度、宽窄面水量和进出水温差为基础，运用商业软件ANSYS模拟了实际生产过程中倒角结晶器铜板温度分布。计算结果表明：距弯月面0～300 mm，倒角结晶器窄面横向温度分布呈W型，和直角结晶器倒U型温度分布有很大差别；距弯月面300～800 mm，角部温度迅速降低，温度分布呈倒U型，和直角结晶器温度分布基本一致；此外，倒角结晶器倒角面的温度梯度较大，倒角面上坯壳与铜板之间的换热热流波动较大，这说明倒角坯的缺陷主要出现在倒角面，这与实际是相符合的。

Based on the dimension of chamfered mold,waterway arrangement,measured copper temperature,cooling water volume and temperature difference between inlet and outlet water in actual production process of Beijing Steel Plant,the commercial software ANSYS was used to simulate the chamfered copper mold temperature distribution in actual production. The results show that from the meniscus 0-300 mm,the lateral temperature distribution on narrow-surface coo-per was W type,which is different from the right-angle mold inverted U type temperature distribution. From the meniscus 300-800 mm,the corner temperature decreases quickly,thus the temperature distribution was inverted U type,which is consistent with right-angle mold temperature distribution. In addition,the temperature gradient is relatively large in cham-fered slope,and the heat-flux fluctuations between the solidified shell and copper is relatively large,which verifies the cracks occurred mainly in the chamfered slope,be consistent with the fact.
