In order to avoid problems with the tundish induction system caused by uneven spacing between coil rings, the induction coil device includes a coil and an outer shell arranged inside and outside, and a plurality of first support columns are arranged in the outer shell. The coil contains a plurality of rings, and each ring is provided with a plurality of first positioning pins. The plurality of first positioning pins arranged on each ring are connected to the plurality of first support columns accordingly.
