Abstract:The unsteady-state heat transfer model on BF copper stave was established. Based on the element birth and death technology of ANSYS, recovery behavior of slag skull on the stave surface was simulated. The growth rhythms of slag skull, as well as the changing process of stave temperature and heat load were analyzed. The result showed that slag skull growth followed the power function. On the analysis condition, the measuring point of copper stave reached maximum temperature 59℃ at the time 0.9 minutes after slag skull dropped off. After 23.5 minutes, the stave temperature got steady. The maximum heat load was 107.8kW/m2. The maximum temperature on the hot face of copper stave reached 123℃.
