Abstract Based on the theory of heat transfer, a mathematical model was developed to simulate temperature drop of hot metal during transfer. The model can be used for special factory, and it was proved that the calculated values were in good agreement with the measured one. And it is also proved that the temperature drop in different steps was different: the temperature drop of hot metal during tapping was the greatest; those during charging, pretreatment, transportation and waiting were relatively smaller. Compared with the mode of hot metal transfer with ladle changing, the mode of using one open ladle had relatively better interface continuity and temperature drop of hot metal could be reduced by about 35%. Hence the mode of using one open ladle is potentially favorable in the future.
