The process is characterized in that, before starting casting, an initialization position is determined for the stopper rod control actuator when the stopper rod is resting on its seat under its own weight and after having filled the tundish equipped with this stopper rod, the actuator is operated to place it in a controlled superclosed position and, to start casting, the actuator is driven according to an imposed movement versus time law, time (t1) for start of casting being determined from this law and the control actuator continues to be driven in opening direction to enable the metal to flow into the ingot mould.
