Abstract：Based on the temperature measured by thermocouple, the finite element heat transfer model for Han Gang?wide-thick?slab continuous casting mold and non-linear model for estimating its heat flux were built. The heat flux of copper plate was calculated through the back calculated model results, and the results were contrasted with the average heat flux calculated by heat balance method, the validity of model was thus demonstrated. The heat flow formulae for the wide and narrow surface of copper plate were confirmed, and the temperature distribution of copper plate was also analyzed. The results show that temperature curve of copper plate hot side is of a wavy distribution, which changes gently; there is the largest temperature difference of 29.4 ℃ near the cold side. The temperature of copper plate decreases with the increase of the distance to meniscus, while the phenomenon of back temperature appears at the mold exit, about recovers 23 ℃.
