Abstract

A method of controlling the level of molten steel in the mold of a continuous casting apparatus comprises sensing the arrival of the molten metal level at a predetermined value at the start of operation of the apparatus, driving dragging rolls, from that point of time onward, at a rotational speed based on a preset value of initial roll speed setting, thereafter sensing when the level has reached the neighbourhood of a higher preset level or measuring a fixed length of time, and, from that point onward, inputting the deviation of the molten metal level in the mold from the preset level to a controller, and driving the dragging rolls by means of signals which combine the output of the controller with the initial roll speed setting. <IMAGE>
