Abstract

Improvements in systems for controlling the level of molten metal in a continuous casting mold, in which system the rate of pouring of molten metal into the mold and the rate of removal of a casting piece therefrom by a motor drive of the rolls takers, are controlled by an error signal that reflects the fluctuation of the level of molten metal in the mold, characterized in that a detector is provided for deviations of the liquid level, which produces an error signal of a polarity and a magnitude indicating the direction of deviation of the liquid level and the degree thereof with respect to a predetermined level, a regulator circuit of the speed of the tapping rollers which is connected to said detector and which changes at the rate of withdrawal of the casting in response to the cited error signal, means coupled to the motor drive of the tapping rollers and that produce a second error signal of one polarity and a magnitude which indicate changes in the selected withdrawal rate, a limiting circuit that produces polarizing voltages that block the second error signal for a preferred range of withdrawal rates, and means that apply a second non-blocked error signal to a control circuit of the liquid level, which changes the rate of pouring of molten metal according to the polarity and magnitude of the second applied error signal.
