Abstract：

In order to accurately predict the change of temperature field of large forgings in actual production and to guide the forging planning, the research methods of forwarded-measurement with reversed solution and forwarded-measurement simulation were adopted to measure the cooling curve of characteristic points during forging air-cooling process. Then, the interface heat transfer coefficient during the air-cooling process was obtained by the Inverse Heat Transfer solver of Deform and inverse heat transfer method, and the blank′s surface temperature curve was got by inputting heat transfer coefficient to the simulation of forging process, which was verified by the measured temperature. Finally, prediction of the temperature field of large forging with 700 mm×700 mm×1500 mm was successfully realized during forging.
