METHOD OF AND APPARATUS FOR CONTROLLING MOLTEN METAL SURFACE IN MOLD OF CONTINUOUS-CASTING MACHINE AND CONTINUOUS-CASTING MACHINE INCLUDING THE APPARATUS

摘要

A method of and an apparatus for controlling a molten metal surface in a mold that are effective to various disturbances are provided. The method and the apparatus for controlling a molten metal surface level in a mold according to the present invention perform the following operations of: measuring the molten metal surface level in the mold of a continuous-casting machine; changing a reference position of oscillation of the mold based on the difference between a molten metal surface setting value set in advance as a desired value of the molten metal surface and a measured value of the molten metal surface level; and making the reference position of oscillation follow molten metal surface fluctuations.
