Abstract

La invención proporciona un método para colada continua de tochos de sección transversal pequeña en el cuál el tocho cuenta con un área de sección transversal no mayor a 500cm2 y una boquilla cilíndrica de inmersión con una sola apertura se utiliza para verter el acero fundido en un molde, caracterizado en que el nivel de acero fundido en la superficie es medido usando un sensor de corriente parásita y el nivel de acero fundido en el molde es controlado en base en el valor medido de esta forma, el movimiento del acero fundido en el molde es ajustado al proporcionar agitación electromagnética, una zona de enfriamiento durante el periodo final de solidificación se encuentra dentro de una cierta sección específica con un rango desde el menisco hacia el punto específico; y se ajusta la velocidad de colada se de manera tal que la sección en la cual la proporción de fase sólida en el centro del tocho sea 0.3-0.99 pueda ser incluida en la zona de enfriamiento durante el periodo final de solidificación, y la cantidad específica de agua secundaria para enfriamiento; la temperatura de la superficie del tocho al entrar a la zona de enfriamiento durante el periodo final de solidificación y la densidad del agua para enfriamiento durante el periodo final de solidificación se optimizan. De esta forma. Los tochos con una sección transversal pequeña pueden ser colados de forma continua para varios grados de acero mientras se reduce de manera estable y confiable la incidencia de porosidad central en el centro del tocho y se mejora la calidad interna del tocho.
