PURPOSE: An ingot manufacturing device and a method using the same for injecting molten steel into a mold for an ingot are provided to accurately control the speed of injecting molten steel flowing into the mold for the ingot, thereby uniformly maintaining a quality of the ingot. CONSTITUTION: An ingot manufacturing device includes a mold for an ingot, a molten steel injecting pipe member, a ladle, an outlet opening/closing door device, a ladle supporting member, a molten steel discharge sensing member, an outlet opened degree sensing member, and a control member. The molten steel discharge sensing member includes a weight sensor sensing the amount of an actual molten steel discharge inside the ladle and measuring the weight of the ladle. The control unit is connected to the outlet opening/closing door device, the molten steel discharge sensing member, and the outlet opened degree sensing member, thereby controlling the opened degree of an outlet. [Reference numerals] (100) Input information about the amount of an actual molten steel discharge inside a ladle; (201S) Calculate the opened degree of an outlet according to a targeted discharge flow; (202S) Open the outlet according to the calculated opened degree of the outlet; (301S) Sense the weight of the ladle; (302S) Calculate the amount of a real discharge flow; (303S) Amount of a targeted discharge flow = Amount of the real discharge flow; (304S) Control the opened degree of the outlet; (400) Complete the discharge of the targeted amount of the molten steel; (AA) Start; (BB) End |
