This paper gives an advanced control to a strip caster with tilting-ladle-type automatic pouring system. The strip caster has been used for producing ferrous and nonferrous sheets. In the process, in order to obtain the high-quality products, it is required that the molten metal in the tundish keep the high liquid level. Therefore, the control system to liquid level in the tundish is proposed in this present paper. In this approach, the mathematical model from the control input into the motor for tilting ladle to the liquid level in the tundish is derived by using hydrodynamics. Then, for reaching quickly the molten metal to the high liquid level and keeping stably the liquid level, the control input into the motor is designed systematically by using the mathematical model. The proposed control system has advantage that it can be constructed simply. And, any sensors for measuring the liquid level are not required in the proposed system.
