A method of and apparatus for automatically filling a continuous casting mold with (steel) melt which is poured in controlled fashion into the continuous casting mold through a bottom hold adapted to be closed by an automatically operated stopper in a distributor channel or intermediate vessel. The stopper carries out predeterined up and down movements, especially in response to the melt level in the continuous casting mold against the action of a force urging the stopper into closing position, while the mold is being filled. The up and down movement of the stopper is realized by an adjustment unit acting directly at the top end of the stopper. The force which urges the stopper into closing position is obtained either from a constant mass or an elastic member attempting to urge the stopper increasingly into closing position as the temperature rises. The elastic member preferably is embodied by closed gas pressure springs, while the adjustment unit preferably is constituted by open spring members corresponding, in structure, to the closed spring members.
