An object of the present invention is to provide a process for continuously casting a molten metal which process suppresses the instability of the initial solidification and stably improves the lubrication and the surface properties of the cast metal, and an apparatus therefore, in the process for continuously casting a molten metal an alternating current is applied to an electromagnetic coil which is provided so that it surrounds a continuous casting mold wall or is embedded in the side wall of the mold, whereby an electromagnetic force is exerted on the molten metal poured into the mold which either oscillates in a constant mode or does not oscillate and is starting to be solidified the process of the present invention also comprises periodically changing the amplitude or waveform of the alternating current to be applied, and the apparatus of the present invention is used for the process.

Apparatus for continuous casting of metal

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.
