ロール型連続鋳造装置における溶鋼堰。 A molten steel weir that is disposed on a pair of rolls arranged parallel to each other and cooperates with these rolls to form a molten steel pool, and is provided at both ends of the rolls and in a direction perpendicular to the roll axis. A pair of first weir bodies provided, and a pair of second weir bodies provided on each roll at a position between the first weir bodies and parallel to the roll axis, and the second weir body
A recess that communicates with the molten steel pool is formed along the roll at the lower part of the weir body that contacts the roll, and the upper edge position of the communication opening of this recess is the lower inner edge position of the second weir body that contacts the roll. In addition, the top edge of the recess is higher than the lower inner edge of the second weir, and the second weir is provided with a supply hole for supplying pressure medium into the recess. Molten steel weir in twin roll continuous casting equipment.
