Formula (1): Tp=(1/D0)x(dD/dx) x100 [%/m] Formula (2): Rp=(1/R0)x(dR/dx)x100 [%/m] In the above formulae, D of the formula (1) is the inside diameter of the mold at a distance of x fr om the superior edge of the mold, and R of the formula (2) is the radius of curvature of curvature outside at the distance of x. Formula (3) Rp=(Tp/2)x( D0/R0) The contact of the cast piece with the internal circumferential surfa ce of the mold becomes uniform and appropriate along the whole circumference , so that a round billet cast piece of high quality free from casting defect can be stably produced.

摘要： A method for continuously casting a billet with a small cross section in which a curved type or vertical type continuous casting machine is used while oscillating the mold upward and downward, is characterized in that: the casting machine is provided with a mechanism for withdrawing speed oscillation wherein the mechanism comprises elastic parts either alone or in combination with dampers between the motors for driving pinch rolls at a speed corresponding to an aimed withdrawing speed and the pinch rolls, the mechanism has structural play in the directions of driving and reverse driving in such a manner that the amount of a play-incurred displacement from the neutral position of the structural play in the direction of billet driving or reverse driving is ± 2 to ± 30 mm in the direction of driving on the pinch roll circumferential length equivalent basis, and the mechanism produces a returning force toward the neutral position, whereby: the billet withdrawing speed during the upward period of mold oscillation becomes slower than the average withdrawing speed and during the downward period of mold oscillation faster than the average withdrawing speed; and operational parameters such as the billet length, the specific amount of secondary cooling water, the casting speed as well as the oscillation amplitude and frequency are optimized. By this method, a billet with a small cross section can be produced continuously in the condition of stable operation while stably reducing the friction force between the mold and the billet and preventing such troubles as sticking of the billet to the mold.

摘要： Un método para colar continuamente un tocho con una sección transversal pequeña en el cual se utiliza una máquina de colada continua de tipo vertical mientras que el molde oscila de manera ascendente y descendente, se caracteriza en que: la máquina de colada cuenta con un mecanismo para la oscilación de velocidad de extracción en el cual el mecanismo está compuesto de partes elásticas ya sea por sí mismas o en combinación con amortiguadores entre los motores para manejar los rodillos tomadores a una velocidad correspondiente a una velocidad de extracción deseada y los rodillos tomadores, el mecanismo cuenta con vibración estructural en la direcciones de la directriz y la directriz de reversa de manera tal que la cantidad de desplazamiento causado por vibraciones desde la posición neutral de la vibración estructural en la dirección de la direcciones de la directriz o la directriz de reversa del tocho sea de ± 2 a ± 30 mm en la dirección de la base equivalente de longitud de la circunferencia del rodillo tomador, y el mecanismo produce una fuerza de retorno hacia la posición neutral, mediante la cual: la velocidad de extracción del tocho durante el periodo de ascenso de la oscilación del molde se vuelve más lenta que la velocidad de extracción promedio y durante el periodo de descenso de la oscilación del molde mayor la velocidad de extracción promedio; y los parámetros operativos tales como la longitud del tocho, la cantidad específica de agua de enfriamiento secundaria, la velocidad de colada además de la amplitud de oscilación y la frecuencia se optimizan. Mediante este método, el tocho una sección transversal pequeña puede ser producido continuamente en condiciones operativas estables mientras se reduce la fuerza de fricción entre el molde y el tocho previniendo problemas tales corno la adhesión del tocho al molde.
