Abstract: A ladle after teeming for a continuous casting and a subsequent slag discharge is mounted on a ladle truck and then moved by the ladle truck to a tapping station. The ladle on the ladle truck is then stationed over a predetermined stand-by time and is then immediately moved to a tapping position to receive a molten steel from a converter. The ladle is quickly heated during the stand-by time, by a regenerative-type burner system carried by a ladle lid which is attached to the ladle to cover the top opening of the ladle. This allows the tapping temperature of the molten steel to be set to a low level, offering advantages such as a remarkable reduction in the consumption of carbonaceous materials as the temperature controller, as well as extended life of ladle refractories through suppression of thermal attack. At the same time, consumption of fuel gas for heating the ladle by the burner system is reduced to contribute to saving of energy.
