Based on the selective heating speciality of microwave, the effects of the BF slag bearing titanium heated by microwave are studied through experiment. The results indicate that the CaTiO3 which crystal grains grow up speedily is a better kind of absorption material for microwave. The changing regularity of temperature and thermal stress along with heating time in the slag specimen are analyzed by numerical simulation. It can be found that the temperature of slag specimen increases rapidly in the microwave radiation field. The maximum temperature of the CaTiO3 heated about 150 s in microwave power of 750 W in slag specimen reaches 868°C, and its maximum temperature can be heated up to 1280°C in microwave power of 2000 W within 150 s. At the same time, the thermal stress in the interface of slag specimen increased.
