【摘要】 薄带钢双辊铸轧整体式磁极电磁侧封装置存在电磁感应强度过大、磁极底部发热严重、同一熔池深度磁场分布不均的缺点。针对整体式磁极的缺点,本文设计并优化了一种新型的分体式磁极电磁侧封机构,采用分体式磁极与线圈绕组克服了熔池底部磁感应强度集中,磁极过饱和等问题。通过三维模型电磁场有限元模拟,分析了分体式磁极侧封结构熔池内磁场、感应电流、电磁压力分布情况,验证了分体式磁极侧封结构的可行性。通过进一步对分体式磁极结构进行优化,得出磁极与熔池之间的距离和磁极的大小是影响侧封的关键因素,优化后的分体式磁极结构侧封效果优于整体式磁极。更多还原

【Abstract】 For the Electromagnetic side seal of twin roll strip casting process, drawbacks were existed in integral pole: the larger electromagnetic induction intensity, the seriously fever at bottom of the pole, the uneven magnetic field distribution in the same depth of molten pool. For the shortcomings of Integral pole, This paper designs a new split electromagnetic poles for side sealing structural configuration, to overcome the issues of integral pole. Through three-dimensional finite element simulation, to analyze the magnetic field, induced current, electromagnetic pressure distribution in the molten metal pool and to verify the feasibility of the split pole side seal structure. By further optimizing the structure of the split pole, the key factor is the size of the poles and the distance between the molten metal pool and poles. And the split pole structure is better than the Integral pole.更多还原
