Abstract
A method of and apparatus for regulating the molten metal level in the mold of a continuous casting installation wherein deviations from a reference value determined by measuring the molten metal level in the continuous casting mold are overcome by regulating the infeed of metal to the mold and/or by regulating the withdrawal speed of the strand from the mold. The invention contemplates simultaneously delivering the adjustment values or magnitudes generated at the metal infeed regulation circuit to the strand withdrawal regulation circuit and changing the predetermined or preset reference value of the withdrawal regulation as a function of such adjustment values in accordance with a predetermined or preset function and this function is prescribed or preset such that the reference value of the withdrawal regulation is only then influenced when the change in the adjustment value in the infeed regulation circuit per unit of time exceeds a predetermined or preset value.
