摘要
通过简化条件下的理论推导和实验测试分别对交变磁场和静磁场计算方法进行了验证 ,在此基础上对电磁连铸复合式结晶器内的磁场进行计算 ,并分析了有无结晶器条件下两种磁场的相互影响·分析结果表明 。
The electromagnetic fields in a novel mold with hybrid electromagnetic fields with combination of alternative and static electromagnetic fields for continuous casting were simulated numerically. The finite difference time domain(FDTD) method was used to simulate the alternative electromagnetic field and the finite difference method was used to simulate the static electromagnetic field. Experiments were performed to validate the verification of the finite difference analysis for static electromagnetic field and the computational results are proved in excellent agreement with the experimental results. The FDTD method for alternative electromagnetic field was validated by analytical solutions of a simplified one dimensional physical model. The reasonable mutual positions for the two electromagnetic fields with and without mold were obtained based on the analysis of numerical simulation. The novel mold with hybrid electromagnetic fields is proved acceptable in the practice.
