Abstract
The present invention relates to a continuous casting apparatus for continuously casting molten metal. More particularly, the present invention provides a method and an apparatus for controlling a surface level of molten metal in a mold when molten metal is continuously cast. The continuous casting apparatus of the invention comprises: a mold in which molten metal is poured and solidified; and an eddy current type molten metal surface level sensor for detecting a molten metal surface level in the mold. In the continuous casting apparatus having an electromagnetic coil arranged in such a manner that the electromagnetic coil surrounds the mold and also having an electric power supply for generating a pulse magnetic field from the electromagnetic coil, there are provided a mechanism for taking out a pulse trigger signal corresponding to the magnetic field from the electric power supply, and a mechanism for controlling a time of detecting a surface of molten metal by the molten metal level sensor.
