针对板坯连铸直轧过程中的感应加热技术进行研究,综合运用纵向磁通和横向磁通2种感应加热方式解决板坯补热问题。以板坯空冷温度场结果为基础,建立板坯感应加热有限元模型。通过 VB对 ANSYS的二次开发调用,实现板坯和线圈相对运动过程中感应加热的三维有限元模拟。结果表明：经过纵向磁通感应加热后板坯边角温度仍然偏低；横向磁通感应补热能有效提高板坯边角温度,2种方法的结合使用对于板坯直轧的实现有一定的指导意义。
The electromagnetic induction heating technology was studied during the continuous casting-direct rolling process,and the problem of slab compensation heating was solved through the application of longitudinal flux and transverse flux induction heating.The finite element model of induction heating was established based on the re-sults of air cooling temperature field.By using the secondary development of ANSYS based on VB,the induction heating during the relative motion of the slab and coil was computed through three dimensional finite element sim-ulation.The results show that the corner temperature of the slab is still low after longitudinal flux induction heat-ing;the corner temperature of the slab can be improved by transverse flux induction heating effectively,and the combination of the two methods possesses a certain instructive significance to continuous casting-direct rolling.
