{"id":11087,"date":"2021-11-09T06:42:19","date_gmt":"2021-11-09T06:42:19","guid":{"rendered":"http:\/\/www.alalloycasting.com\/?p=11087"},"modified":"2021-11-09T06:42:19","modified_gmt":"2021-11-09T06:42:19","slug":"casting-nozzle-for-conveying-aluminum-liquid","status":"publish","type":"post","link":"https:\/\/www.alalloycasting.com\/es\/casting-nozzle-for-conveying-aluminum-liquid\/","title":{"rendered":"Boquilla de colada para el transporte de aluminio l\u00edquido"},"content":{"rendered":"

En el proceso de producci\u00f3n de fundici\u00f3n y laminaci\u00f3n de doble rodillo de bandas de aluminio, la boquilla de fundici\u00f3n es el componente m\u00e1s cr\u00edtico para el transporte del aluminio fundido. Su estructura influye directamente en que el aluminio fundido pueda fluir de forma uniforme y constante hacia la zona de fundici\u00f3n-laminaci\u00f3n, lo que a su vez afecta a la calidad de las planchas fundidas y laminadas e incluso a la estabilidad y el buen funcionamiento de la producci\u00f3n de las mismas.<\/p>\n

El proceso de colada y laminaci\u00f3n se caracteriza por la inyecci\u00f3n de metal fundido en la zona en forma de cu\u00f1a de los dos rodillos de enfriamiento a trav\u00e9s de la boquilla de colada, de modo que el metal fundido se solidifica y se deforma para producir directamente bandas de diferentes espesores. Por lo tanto, el campo de flujo y el campo de temperatura del metal fundido en la cavidad de la boquilla no solo afectan a la estabilidad de la producci\u00f3n de colada y laminaci\u00f3n, sino que tambi\u00e9n desempe\u00f1an un papel clave en la calidad de la banda, por ejemplo, en lo que respecta a las burbujas de aire, las bandas calientes y las barreras fr\u00edas.<\/p>\n

La boquilla de colada para la distribuci\u00f3n del flujo de aluminio l\u00edquido se realiza mediante un bloque de derivaci\u00f3n fijado en la cavidad. Dado que el bloque de derivaci\u00f3n fijo no se puede ajustar din\u00e1micamente en l\u00ednea, en cuanto se produce una distribuci\u00f3n del flujo gravemente inadecuada y surgen problemas de calidad, es necesario interrumpir la producci\u00f3n de colada y laminaci\u00f3n y sustituirla por una boquilla de colada con redistribuci\u00f3n. Es evidente que la tecnolog\u00eda de distribuci\u00f3n del flujo no puede satisfacer los requisitos de la producci\u00f3n de fundici\u00f3n y laminaci\u00f3n; especialmente en condiciones de fundici\u00f3n r\u00e1pida de bandas finas, los defectos de la tecnolog\u00eda de distribuci\u00f3n del flujo existente resultan a\u00fan m\u00e1s evidentes.<\/p>\n

\"\"<\/p>\n

El dispositivo de distribuci\u00f3n del flujo en la cavidad de la boquilla de colada por laminaci\u00f3n incluye un canal de colada, un compartimento delantero<\/a>, una boquilla de colada, una oreja lateral, un mecanismo de elevaci\u00f3n vertical y una barra deslizante de desplazamiento horizontal.<\/p>\n

Con el fin de llevar a cabo un control en l\u00ednea de la distribuci\u00f3n del flujo para resolver los problemas de alteraci\u00f3n de la forma del lingote, defectos de forma e inestabilidad del proceso provocados por los cambios en el campo de flujo y el campo de temperatura durante los procesos de fundici\u00f3n y laminaci\u00f3n, y para crear un sistema de control en bucle cerrado de la planitud mediante un detector de planitud, se eliminan en l\u00ednea los diversos defectos causados por una distribuci\u00f3n inadecuada.<\/p>","protected":false},"excerpt":{"rendered":"
