Abstract
A continuous caster is controlled by a method anticipating the liquidus temperature in the mold of the caster to prevent premature solidification. The temperature in the tundish is measured and based upon the tundish temperature and the resistance time of the molten metal in the tundish, an equivalent liquidus temperature window is defined and the speed of the continuous caster is controlled to maintain this window of operation of the tundish.
