Abstract

PURPOSE:To prevent sticking of Al2O3, etc. on the inside surface of a nozzle used for continuous casting by providing spiral grooves or projections on the inside wall of said nozzle thereby giving rotating force to the molten steel falling in the nozzle. CONSTITUTION:In continuous casting work, spiral grooves or projections 2 are provided on the inside wall of a refractory nozzle 1 used between a ladle and a tundish and between a tundish and a mold. When molten steel falls in the nozzle 1 and strikes against the grooves or projections 2 while it is flowing out through discharge holes 3, the force of the sum of the static pressure and dynamic pressure of the molten steel generates the componetn of force in a horizontal direction, thereby giving swirling flow with the central axis of the nozzle as an axis to the molten steel. The swirling flow acts as shearing force on the inside wall of the nozzle, thereby preventing sticking of Al2O3.
