Boquilla de la cubeta de distribuci\u00f3n<\/a> es un problema complejo que provoca una disminuci\u00f3n de la productividad, defectos de calidad y un aumento de los costes de producci\u00f3n.<\/p>\n

El primer paso de un programa destinado a reducir la obstrucci\u00f3n de las boquillas consiste en llevar a cabo un an\u00e1lisis cuantitativo en tiempo real que incluya un factor de obstrucci\u00f3n de las boquillas, la tasa de variaci\u00f3n de la obstrucci\u00f3n, la velocidad m\u00e1xima posible de colada e indicadores de defectos o de defectos inminentes.<\/p>\n

Una interfaz gr\u00e1fica de usuario con archivo de datos es una herramienta de lo m\u00e1s eficaz.
\nEl siguiente paso del programa contra las obstrucciones consiste en identificar el material que provoca la obstrucci\u00f3n mediante an\u00e1lisis macrosc\u00f3picos, microsc\u00f3picos y qu\u00edmicos, y, a continuaci\u00f3n, clasificar el tipo de obstrucci\u00f3n. A continuaci\u00f3n, deben aplicarse los procedimientos correctivos utilizando el monitor de obstrucciones en tiempo real como indicador de eficacia.<\/p>\n

\"Boquilla<\/p>\n

Aunque las pr\u00e1cticas recomendadas variar\u00e1n en cierta medida en funci\u00f3n de la planta y el grado, en la siguiente lista de 20 puntos se intenta resumirlas: 1. Reducir el arrastre de escoria del horno hacia la cuchara;
\n2. Reducir el potencial de ox\u00edgeno de la escoria de la cuchara a unos 2 % de FeO;
\n3. Aumentar la basicidad de la escoria de la cuchara para acercarse a la saturaci\u00f3n de cal;
\n4. Utilizar cal al mismo tiempo que se realiza la desoxidaci\u00f3n con aluminio;
\n5. Realizar un agitado de enjuague controlado de varios minutos como \u00faltimo paso del refinado en cuchara;
\n6. Utilizar la intensidad de la vibraci\u00f3n del cuchar\u00f3n como par\u00e1metro de control de la agitaci\u00f3n con arg\u00f3n;
\n7. Evitar que la escoria pase de la cuchara de colada al repartidor;
\n8. Utilizar un fundente b\u00e1sico y fluido para el dep\u00f3sito de colada, con un espesor suficiente para cubrir toda la superficie;
\n9. Abrir cada cuchara nueva con la cubierta sumergida;
\n10. Evitar la turbulencia superficial y el arrastre de escoria del dep\u00f3sito de distribuci\u00f3n;
\n11. Llenar el dep\u00f3sito intermedio con arg\u00f3n al inicio de una secuencia;
\n12. Utilizar arena para boquillas y fundente para artesa con bajo contenido en FeO;
\n13. Utilizar el menor n\u00famero posible de componentes en la boquilla y garantizar un buen sellado entre ellos;
\n14. Asegurarse de que los componentes de la boquilla est\u00e9n bien alineados;
\n15. Utilizar la inyecci\u00f3n de arg\u00f3n a trav\u00e9s de los poros o canales de los materiales refractarios de la tobera;
\n16. Controlar la contrapresi\u00f3n y el caudal de arg\u00f3n en cada punto de entrada;
\n17. Comprobar los SEN para detectar indicios de reducci\u00f3n qu\u00edmica de impurezas mediante carbono;
\n18. Utilizar el rango adecuado de inyecci\u00f3n de calcio para la modificaci\u00f3n de la inclusi\u00f3n;
\n19. A\u00f1adir azufre a los grados resulfurados \u00fanicamente tras el tratamiento con calcio y el enjuague con agitaci\u00f3n;
\n20. Mantener un potencial de ox\u00edgeno suficiente para evitar la formaci\u00f3n de espinela de aluminato de magnesio.<\/p>","protected":false},"excerpt":{"rendered":"
