[Scope of Claim for Utility Model Registration] The operating state of the level control unit into which the value from the level detector that detects the level of molten steel in the mold below the tundish is input, and the hydraulic cylinder for driving the sliding nozzle installed at the lower end of the tundish. and a servo amplifier, into which values from the position detector and the level control section are input, and which sends an operation control signal to a servo valve that sends hydraulic fluid to the hydraulic cylinder. It is a molten steel level control device, and the servo amplifier is configured to control the responsiveness of an electro-hydraulic servo system due to the difference in piston pressure receiving area between when the sliding nozzle in the hydraulic cylinder performs an opening operation and when it performs a closing operation. 1. An in-mold molten steel level control device for continuous casting, characterized in that a compensator is provided for compensating for the difference in molten steel level in a mold using the electro-hydraulic servo system.
