Document Type and Number:
Japanese Patent JPS6355389
Kind Code:
B2
Abstract:
An electromagnetic stirrer of linear induction motor type for a continuous casting machine, whose coils are arranged to differ a distance between poles of theeven function components of the travelling wave current distribution with respect to the center thereof from that of the odd function components so that a larger electromagnetic force is generated, thereby eliminating the internal defects, such as macro-segregation or center porosity, and improving quality of the ingot. Also, the electromagnetic stirrer, even when attached to a small-sized mold or a mold of small aspect ratio, demonstrates the sufficient effect.
