In the balloon 111 control method, the balloon detection device 8 is arranged in a swinging manner at a position where the detection beam 86 is tangential to the balloon 111 with an optimal diameter, wherein the optimal diameter refers to a diameter of a horizontal section where the balloon 111 has a maximum diameter when the balloon is located at a minimum distance from the ingot can 101.
