PURPOSE: To prevent the overflow caused by rapid riding of molten steel surface frequently generate at the initial stage of casting by precisely measuring the molten steel surface height in a continuous casting mold from the initial stage of the casting.
CONSTITUTION: A molten metal surface height control device is constituted by combining an electrode type molten metal surface height meter 11 having four sets of electrodes 12a-12d composed of two lead wires and arranged on the inner surface or its neighborhood of the continuous casting mold 1 while mutually separated in the casting direction at these tip parts of the electrodes 12a-12d and a device for adjusting the opening degree of a sliding nozzle in a tundish arranged above the continuous casting mold 1 based on the outputted signal from the electrode type molten metal surface height meter 11.
