摘要
针对特殊钢成捆棒材切割后,因表面温差过大会出现端部开裂的现象,实际生产中需要特殊处理.利用ANSYS电磁-热耦合技术,分析了导磁体对多根棒材横向磁通感应加热的影响.结果表明:导磁体能降低磁阻,提高整捆棒材的加热效率,并且随着线圈一侧导磁体面积的增大,加热效率增大;双导磁体更有利于感应加热整捆棒材的温度分布均匀;同时,通过模型简化将模拟温度与实验温度进行对比,结果基本吻合.
In view of the end cracking of special steel bar caused by the surface temperature difference over the assembly after cutting, special treatment is needed in practical production. The effect of magnetic conductors on the transverse flux induction heating of many bars was analyzed. The results show that the magnetoconductive magnets can reduce the magnetoresistance and improve the heating efficiency of the whole bar, and the heating efficiency increases with the increase of the area of the magnetic conductors on the other side of the coil. The double magnetic conductors are more favorable to the uniform temperature distribution of the whole bundle of bars heated by induction. At the same time, the simulation temperature was compared with the experimental temperature by the simplified model, and it was found that the simulation and experimental result were in good agreement.
