Abstract
A high frequency coil for producing a water-drop-shaped drawing hole structure with eight or nine silicon cores relates to a high frequency coil. Drawing holes or material holes (11) are arranged in the middle of the round high frequency coil (2), and eight flow guiding grooves (12) are radially arranged on the drawing holes or the material holes. External ends of the eight flow guiding grooves are arranged among the eight drawing holes (5), V-shaped flow guiding openings (6) are respectively arranged on one side of the eight drawing holes facing the drawing holes or the material holes, and spaces are reserved between the sharp ends of the V-shaped flow guiding openings and the drawing holes or the material holes. Connection seats are respectively arranged at the outer ends of a water inlet pipeline (8) and a water outlet pipeline (13). The high frequency coil overcomes the shortcoming that cylindrical crystal is in an oval shape caused by the fact that temperature of the outer lateral face and temperature of the inner lateral face of the drawing holes around the periphery are different, the V-shaped flow guiding openings enable current of the drawing holes around the periphery to be evenly distributed around the drawing holes, and the oval degree of the cylindrical crystal is effectively reduced.
