Las puntas y la boquilla de colada, la caja de entrada moldeada al vac\u00edo y el dep\u00f3sito de distribuci\u00f3n son los factores clave para garantizar la producci\u00f3n de bobinas de aluminio mediante colada y laminaci\u00f3n.<\/p>\n

Tras bajar la caja de entrada y el dep\u00f3sito intermedio moldeados al vac\u00edo (tambi\u00e9n denominados compartimento delantero<\/a>) temperatura, se pueden reducir los defectos de grano grueso provocados por una temperatura excesiva, se puede reducir la reacci\u00f3n de oxidaci\u00f3n y formaci\u00f3n de escoria del material fundido a alta temperatura y se puede garantizar la calidad de la chapa laminada en caliente.<\/p>\n

Debido al aumento de la velocidad de colada, el tama\u00f1o de la segunda fase en la estructura observada a gran aumento de la bobina laminada en caliente es menor, est\u00e1 m\u00e1s disperso y se distribuye de forma m\u00e1s uniforme. Las finas part\u00edculas de compuestos met\u00e1licos intermedios pueden mejorar las propiedades mec\u00e1nicas del material y aumentar su resistencia sin reducir su plasticidad.<\/p>\n

Debido al aumento de la velocidad de colada-laminado, mejoran las condiciones de solidificaci\u00f3n de la masa fundida, aumenta la densidad de la estructura interna de la bobina colada y laminada, y mejora significativamente la calidad de la estructura interna. Sin embargo, el aumento de la velocidad de colada-laminaci\u00f3n tambi\u00e9n est\u00e1 limitado a un determinado rango. A medida que aumenta la altura vertical del intervalo de cristalizaci\u00f3n de la aleaci\u00f3n, la velocidad de colada-laminaci\u00f3n debe reducirse en consecuencia.<\/p>\n

\"Colada<\/p>\n

Para hacer frente al enfriamiento y al aumento de la velocidad en las fases de colada y laminaci\u00f3n, teniendo en cuenta el aumento de la separaci\u00f3n entre los rodillos de la tobera, es necesario mejorar el m\u00e9todo de distribuci\u00f3n del flujo de la tobera, as\u00ed como la uniformidad de la temperatura y de la presi\u00f3n del fluido en la cavidad de la tobera, optimizando la distribuci\u00f3n de los bloques de obstrucci\u00f3n en las puntas de la m\u00e1quina de colada. Para adaptarse al enfriamiento y al aumento de la velocidad de la colada y la laminaci\u00f3n, es necesario aumentar la intensidad de enfriamiento con el fin de garantizar el equilibrio t\u00e9rmico en la producci\u00f3n.<\/p>\n

Reducir la temperatura de la caja de entrada y del dep\u00f3sito de distribuci\u00f3n, y aumentar la velocidad de colada, no solo permite aumentar la eficiencia de la producci\u00f3n, sino que tambi\u00e9n mejora la fluidez de la masa fundida y las condiciones de solidificaci\u00f3n de la misma, y aumenta la densidad de la estructura interna de la bobina laminada en caliente.<\/p>","protected":false},"excerpt":{"rendered":"
