The temperature and solidification of molten slag during transportation may affect the slag hot braised process. In the present work, the effects of solidified thickness of slag layer due to natural convection caused by molten slag density were numerically simulated. The results showed that the temperature of molten slag decreased and the slag density increased near the pot wall. Slag with higher density flowed down the pot wall and the slag with lower density flowed up to the slag surface, respectively. Circulation was formed between the pot wall and the center, which caused the higher temperature about 150 K in the middle part of pot wall than the bottom. The maximum thickness of the slag layer ~100 mm appeared near the filling level, much higher than the thicknesses of 70 mm at the bottom and 30 mm on the side.
