PULLING CONTROL DEVICE FOR SINGLE CRYSTAL INGOT GROWTH AND PULLING CONTROL METHOD APPLIED THERETO

摘要

The present invention relates to a pulling control device for growing a single crystal ingot capable of controlling an eccentricity of a single crystal ingot by varying a seed rotation number in real time, and a pulling control method applied thereto.;According to the present invention, a pulling control device for growing a single crystal ingot and a pulling control method applied thereto may minimize that a seed rotation number (f) is set to a specific rotation number (fo) causing a resonance phenomenon of a melt by providing a target seed output rotation number (T_f_out) that varies in real time so as to match a rotation form for each length of an ingot according to inputting a target seed input rotation number (T_f_in) and controlling a rotation number (f) of a seed cable, and it is possible to prevent fluctuation of the melt and an eccentricity phenomenon of the ingot.
