ABSTRACT:
A method of, and apparatus for, regulating the bath level of a continuous casting mold by means of electromagnetic alternating fields which contemplates measuring changes in the inductance as a function of the bath level and employing such measured changes as an input signal for bath level regulation. According to specific aspects of the invention an electromagnetic primary alternating field is directed at one mold wall from the side of the continuous casting mold where the molten metal is poured-in. This alternating field induces a current in the mold wall and a secondary electromagnetic alternating field produced by such current is measured and employed as an input signal for regulation of the bath level in the continuous casting mold.
