While a mold assembly providing an antechamber for the mold is fixed in the operating position, another such mold antechamber assembly is set up, adjusted and preheated in a standby position, and mechanical displacement arrangements make possible a rapid substitution of the mold assembly in the standby position for the mold assembly in the operating position, either in case trouble develops with the latter or when it is desired to shift from operations with a mold of one cross section to operations with a mold of another cross section. The cast rod is pulled horizontally out of the mold. Operating and standby positions are provided on a rotatable positioning table. A reservoir oven is arranged for discharging molten metal into the antechamber located in the operating position as needed to maintain the melt level in the antechamber of the operating mold assembly within prescribed limits.
