Temperature Field during Melting and Solidification of Glass with Electromagnetic Cold Crucible

Through using cold crucible to curing nuclear waste and deeply burying solidified body, the detriment of nuclear waste for environment could be prevented. The temperature distribution of melt interior will impact the quality of the solidified body directly. A temperature field calculation model was established by Ansys software. Then accuracy of the model was verified by experiments. The distribution of temperature field in melt was simulated and the distribution of temperature was analyzed at different power parameters by using the model. The results reveal that with the increase of current value and frequency, heating time to the operating temperature can be shortened, however, the temperature gradient can be enlarged, which cause the uneven distribution in melt. Smelting process should set mechanical agitation on the basis of physical conditions.
