Abstract

Proveer un método de colada continua y una máquina de colada continua, capaces de hacer flotar y separar inclusiones no metálicas a base de óxido en acero fundido en una vasija de vertido de un modo eficiente. En el interior de una vasija de vertido, las posiciones relativas de una tobera para colada de un cucharón y la vasija de vertido y una cantidad de acero fundido en la vasija de vertido se controlan de manera tal que una posición de establecimiento de una tobera para colada para verter el acero fundido, desde el interior del cucharón, y una profundidad de acero fundido en la posición de establecimiento cumplan con la fórmula (1) y, con preferencia, también cumplan con la fórmula (2):2xH < L1 + L2 + L3 < 4xH (1) 2xH < L4 < 4xH (2) en la cual, L1 indica una distancia desde una superficie de la pared lateral sobre el lado opuesto a la tobera de flujo saliente del acero fundido, tal como se ve desde el punto de vertido del acero fundido, hasta una posición directamente por debajo del punto de vertido del acero fundido sobre una superficie inferior de la vasija de vertido para colada continua; L2 indica una longitud de una porción inmersa en acero fundido de una pared lateral, sobre el lado opuesto a la tobera de flujo saliente del acero fundido, tal como se ve desde el punto de vertido del acero fundido; L3 indica una distancia desde una línea central de la tobera para colada del acero fundido hasta la superficie de la pared lateral, sobre una superficie del acero fundido del acero fundido; L4 indica una distancia horizontal entre un punto de vertido de acero fundido y un punto del flujo saliente del acero fundido y H indica la profundidad del acero fundido en la posición de la línea central de la tobera para colada.Provide a continuous casting method and a continuous casting machine, capable of floating and separating nonmetallic inclusions based on molten steel oxide in an efficient pouring vessel. Inside a pouring vessel, the relative positions of a pouring nozzle of a ladle and the pouring vessel and an amount of molten steel in the pouring vessel are controlled such that a setting position of a nozzle for casting to pour the molten steel, from the inside of the ladle, and a depth of molten steel in the setting position comply with the formula (1) and, preferably, also comply with the formula (2): 2xH <L1 + L2 + L3 <4xH (1) 2xH <L4 <4xH (2) in which, L1 indicates a distance from a surface of the side wall on the side opposite to the outflow nozzle of molten steel, as seen from the pouring point of molten steel, to a position directly below the pouring point of molten steel on a lower surface of the pouring vessel for continuous casting; L2 indicates a length of a portion immersed in molten steel of a side wall, on the side opposite to the outflow nozzle of molten steel, as seen from the pour point of molten steel; L3 indicates a distance from a central line of the casting nozzle of the molten steel to the surface of the side wall, on a surface of the molten steel of the molten steel; L4 indicates a horizontal distance between a pour point of molten steel and a point of the outgoing flow of molten steel and H indicates the depth of molten steel at the center line position of the casting nozzle.
