玻璃固化用电磁冷坩埚温度场研究
发布时间：2018-08-29 10:13
【摘要】：使用冷坩埚对核废料进行固化处理后将固化体深埋可以防止核废料污染环境,而固化时熔体的温度分布将直接影响固化体的质量。利用Ansys软件建立了温度场计算模型,并通过试验验证了模型的准确性。利用此模型分析了冷坩埚玻璃固化时熔体不同位置以及不同电源参数条件下的温度分布。结果表明,随着电流值和频率的增加,加热到工作温度的时间缩短,但温度梯度增大,使熔体内部温度分布不均匀。熔炼过程中应根据实际情况添加机械搅拌。
[Abstract]:Using cold crucible to cure nuclear waste can prevent nuclear waste from polluting the environment, and the temperature distribution of melt during solidification will directly affect the quality of solidified body. The calculation model of temperature field is established by using Ansys software, and the veracity of the model is verified by experiments. By using this model, the temperature distribution of the melt at different positions and different power supply parameters during glass curing in a cold crucible was analyzed. The results show that with the increase of current value and frequency, the time of heating to the working temperature is shortened, but the temperature gradient increases, which makes the internal temperature distribution of the melt uneven. Mechanical stirring should be added to the smelting process according to the actual situation.
