Abstract 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 cooper 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 chamfered 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.
