El panel de soporte de la boquilla de fundici\u00f3n de la cavidad de la boquilla de alimentaci\u00f3n es un componente clave del proceso de fundici\u00f3n y laminaci\u00f3n electromagn\u00e9ticas.<\/strong>, y su estabilidad estructural est\u00e1 directamente relacionada con la estabilidad plana de la boquilla de fundici\u00f3n.<\/p>\n

Est\u00e1 fabricado con una malla de fibra refractaria. La malla de fibra contiene cantidades aproximadamente iguales de al\u00famina y s\u00edlice, y contiene una soluci\u00f3n con s\u00edlice coloidal.<\/strong>
\nLa composici\u00f3n t\u00edpica de la fibra es de 51,2% de al\u00famina, 47,4% de s\u00edlice y 0,7% de \u00f3xido de boro y \u00f3xido de sodio.
\nPara fabricar un fieltro adecuado, estas fibras se dispersan en una soluci\u00f3n acuosa que contiene una dispersi\u00f3n de s\u00edlice coloidal.
\nAl diluir los componentes disponibles, estos contienen aproximadamente 30% de s\u00f3lidos de silicio coloidales.
\nEl tama\u00f1o medio de las part\u00edculas de s\u00edlice coloidal es de unas 17 micras, es decir, unos 48 \u00e1tomos de silicio por part\u00edcula.
\nLa s\u00edlice coloidal se estabiliza mediante la adici\u00f3n de una cantidad suficiente de hidr\u00f3xido de sodio o hidr\u00f3xido de litio (metales alcalinos) a la soluci\u00f3n, y el valor del pH oscila entre 9,5 y 10,5 aproximadamente.
\nEste ingrediente se diluye en agua para formar una soluci\u00f3n que contiene aproximadamente un 22% de s\u00edlice coloidal en s\u00f3lidos, en peso. Se dispersan en la soluci\u00f3n suficientes fibras refractarias para formar una suspensi\u00f3n con un contenido de fibras de aproximadamente un 5%.<\/p>\n

\"Cavidad<\/p>\n

Si necesita la cavidad de la boquilla de alimentaci\u00f3n para el proceso de colada continua y laminaci\u00f3n, visite www.adtechamm.com o p\u00f3ngase en contacto directamente con Sales@adtechamm.com<\/strong>
\nPor lo general, la distancia entre las partes situadas aguas arriba de las dos mitades del cabezal de alimentaci\u00f3n es suficiente para mantener el espacio necesario entre los bordes situados aguas abajo del cabezal de fundici\u00f3n.
\nSi fuera necesario, se pueden colocar uno o varios espaciadores adicionales en el centro, entre la parte de entrada y el borde de salida.
\n. Esta junta, en caso de utilizarse, deber\u00eda tener una forma razonablemente aerodin\u00e1mica para evitar que obstaculice el flujo de metal a trav\u00e9s del extremo de alimentaci\u00f3n.<\/p>\n

El espacio entre los separadores permite que el metal l\u00edquido penetre en el hueco que hay entre las dos mitades de la punta de alimentaci\u00f3n.<\/strong>
\nEl \u00e1rea transversal del espacio situado en la parte aguas arriba de la punta met\u00e1lica de paso es, preferiblemente, mayor que el \u00e1rea transversal del hueco entre los bordes aguas abajo del metal. punta de flujo continuo<\/a>.
\nEsto garantiza que la velocidad del metal aumente, en lugar de disminuir, a medida que atraviesa la punta.
\nEl canal por el que fluye el metal fundido entre la parte aguas arriba y la parte aguas abajo tiene, evidentemente, una secci\u00f3n c\u00f3nica, lo que tambi\u00e9n resulta ideal para reducir el cambio brusco de la velocidad del flujo de metal en la parte superior de la m\u00e1quina de colada continua.
\nEsta disposici\u00f3n permite minimizar la discontinuidad del flujo de metal y evitar la introducci\u00f3n de impurezas en la l\u00e1mina delgada formada por la m\u00e1quina de colada continua.
\nLa superficie interior, pr\u00e1cticamente plana, tambi\u00e9n permite que el elemento sea m\u00e1s grueso cerca del borde de salida y aumente su resistencia.<\/p>","protected":false},"excerpt":{"rendered":"
