Abstract
Two PDEs are proposed to represent the sheet temperature distribution in the hot FLD test process with the heat transfer considered, such as convection, conductance and radiation heat transfer. The test about sheet temperature distribution in hot FLD test is carried out, the experimental data is compared with the theoretical one. The heat flux of different areas of the sheet is calculated and the result proves that the contact heat flux between sheet and punch is the major factor to affectthe sheet temperature distribution. Meanwhile, the temperature distribution of the area which contacts with the punch is calculated by using the die height as a parameter, the results represent that the die height affectsthe sheet temperature slightly.
