Abstract

Se describen un método y un aparato para agitacion electromagnética de metales fundidos en un estado avanzado de solidificacion, tal como el que se puede utilizar en la colada continua de palanquillas o tochos de acero. Se proporcionan al menos un primer y un segundo agitador para generar un primer y un segundo campo magnético giratorio de una frecuencia diferente en torno a un eje de metal fundido bajo solidificacion. Los agitadores están dispuestos en torno al metal fundido con la suficiente proximidad entre sí de manera que sus respectivos campos magnéticos se superpongan para producir un campo magnético modulado. Los campos magnéticos de los respectivos agitadores pueden tener direcciones de rotacion ya sea comunes, u opuestas. La agitacion modulada producida por los campos magnéticos trae como resultado flujos primarios y secundarios oscilantes y, por lo tanto, turbulencia dentro del lote fundido, en la region en la cual la temperatura del material fundido en su eje central está por debajo del nivel de temperatura líquidus y se forma al menos el 10% del material sustancialmente solidificado. El flujo turbulento que crea este método de agitacion detiene la formacion de las estructuras cristalinas en el lote fundido y mezcla el material fundido enriquecido con soluto de la region central con el volumen del lote, lo cual posteriormente trae como resultado mejoras en la estructura de solidificacion y en la calidad interna general de los productos moldeados.A method and apparatus for electromagnetic stirring of molten metals in an advanced state of solidification are described, such as that which can be used in the continuous casting of steel billets or billets. At least a first and a second agitator are provided to generate a first and a second rotating magnetic field of a different frequency around a molten metal shaft under solidification. The stirrers are arranged around the molten metal with sufficient proximity to each other so that their respective magnetic fields overlap to produce a modulated magnetic field. The magnetic fields of the respective stirrers may have either common or opposite directions of rotation. The modulated agitation produced by the magnetic fields results in oscillating primary and secondary fluxes and, therefore, turbulence within the molten batch, in the region in which the temperature of the molten material at its central axis is below the temperature level liquid and at least 10% of the substantially solidified material is formed. The turbulent flow created by this stirring method stops the formation of the crystalline structures in the molten batch and mixes the solute-enriched molten material from the central region with the volume of the batch, which subsequently results in improvements in the solidification structure. and in the overall internal quality of molded products.
