Abstract

PURPOSE: To effectively seal the gap between the pouring pipe and the ladle nozzle from the atmosphere, by fixing the sealing box to the top end of the pouring pipe, and by attaching the bored cover slidably to the top end of the sealing box using the spring unit.
CONSTITUTION: The ladle 50 is moved so as to insert its nozzle 52 into the hole 7 bored in the cover 6. Hereupon, the ladle nozzle 52 and the edge 8 are slidingly contacted against each other and the sealing is formed. Since the slidable cover 6 is being pushed by the spring, the cover 6 is tight pressed against the support 51 by moving the ladle 50 in a suitable distance downward, and is sealed by the refractory wire 11. Next, the gap between the ladle nozzle 52 and the pouring pipe 53 is perfectly sealed from atmosphere by blowing the gas into the sealing box 1; as a result, the oxidation of the molten steel 54 or the absorption of atmospheric nitrogen are effectively prevented.
