SINGLE BELT TYPE CONTINUOUS CASTING METHOD AND MOLTEN STEEL POURING DEVICE

PURPOSE:To easily adjust molten metal pouring quantity, to uniformize the pouring quantity distribution and to obtain the stable supply by making a partition wall at the front part of a trough part the movable wall so as to be adjustable to the position in the front and the rear parts, making a pouring hole at the front part openable/closable and adjusting the position of the front wall surface to adjust the molten steel pouring quantity. CONSTITUTION:Since the front wall of the trough part 9 of a tundish 7 is made to be the movable wall 13 so as to be adjustable to the position at the front and the rear parts and the pouring hole 8 at the front part of the trough part is made to be openable/closable, the position of this movable wall 13 is adjusted without changing the tundish 7 and the trough part 9, and the molten metal pouring quantity is adjusted by adjusting the molten metal pouring range and the positional head of molten steel, and the productivity can be changed. Further, the molten metal pouring quantity can be adjusted by adjusting the opening degree of the pouring hole 8a at the rear end side of the trough part 9 of the tundish with a sliding nozzle 17, and the productivity can bc changed without changing the tundish trough.
