Canal de fundici\u00f3n de aluminio fundido<\/strong> Es el canal por el que discurre el aluminio fundido desde el horno est\u00e1tico hasta la caja delantera. Para evitar la p\u00e9rdida de calor del aluminio fundido, el canal de vertido debe contar con un buen aislamiento t\u00e9rmico.
\nA la hora de garantizar la duraci\u00f3n del proceso, la longitud del canal de fundido debe ser lo m\u00e1s corta posible, y es preferible que sea herm\u00e9tico, con el fin de evitar que la temperatura de la masa fundida descienda en exceso y de prevenir la contaminaci\u00f3n secundaria de la misma.
\nPara facilitar el mantenimiento, el canal de descarga suele ser de tipo desmontable; la carcasa exterior est\u00e1 soldada con chapa de acero, y el revestimiento interior est\u00e1 compuesto por arcilla de silicato de aluminio e hilos de amianto.
\nPara mantener la temperatura del aluminio fundido, el canaleta de aluminio<\/a> Se puede recubrir con materiales refractarios que conserven el calor, o bien se puede instalar en el canal de fundici\u00f3n un dispositivo de calentamiento con alambre de resistencia o una varilla de carburo de silicio.
\nAlgunas f\u00e1bricas tambi\u00e9n utilizan boquillas de llama de gas para calentar y garantizar la temperatura del canal de fundici\u00f3n.<\/p>\n

\"Canal<\/p>\n

La posici\u00f3n relativa entre el canal de fundici\u00f3n de aluminio y la caja delantera es diferente, y el flujo del aluminio l\u00edquido tambi\u00e9n es distinto.
\nEn la figura a se muestra el m\u00e9todo de suministro vertical de aluminio l\u00edquido.
\nEste m\u00e9todo de suministro de aluminio l\u00edquido se realiza de arriba abajo, y el canal de vertido y la caja delantera se encuentran a diferentes niveles.
\nEste m\u00e9todo permite controlar f\u00e1cilmente el nivel de l\u00edquido de la caja delantera, y el dispositivo de control del nivel de l\u00edquido es relativamente sencillo; sin embargo, debido a la ca\u00edda que se produce durante el proceso de flujo del aluminio l\u00edquido desde el canal de vertido hasta la caja delantera, el nivel de l\u00edquido desciende al pasar del canal de vertido a la caja delantera, lo que puede provocar f\u00e1cilmente una absorci\u00f3n secundaria del aluminio l\u00edquido y la formaci\u00f3n de escoria gaseosa.<\/p>\n

En la figura b se muestra el flujo de suministro de l\u00edquido de aluminio en el sistema de inyecci\u00f3n lateral.
\nEl canal y la caja delantera est\u00e1n al mismo nivel.
\nEste m\u00e9todo de alimentaci\u00f3n evita la ca\u00edda del aluminio fundido, ya que la l\u00ednea central del canal de vertido se encuentra a la misma altura que la l\u00ednea central de la caja delantera, y la l\u00ednea central de la boca del horno vertical es m\u00e1s baja que la l\u00ednea central del laminador.
\nLa pel\u00edcula de \u00f3xido que se forma en la superficie del aluminio fundido act\u00faa como capa protectora. El aluminio fundido se introduce bajo la pel\u00edcula de \u00f3xido de forma sumergida, lo que reduce considerablemente el fen\u00f3meno de succi\u00f3n y la formaci\u00f3n de escoria durante el flujo del aluminio fundido.
\nSin embargo, el dispositivo de control del nivel de l\u00edquido resultante de esta forma es m\u00e1s complicado.<\/p>\n

\u00bfC\u00f3mo evitar que se active la canaleta de descarga de escoria?
\n(1) Controlar de forma adecuada la temperatura de la escoria.
\n(2) Controlar de forma razonable la altura de la superficie de la escoria para evitar un volumen instant\u00e1neo excesivo de la misma.
\n(3) Evitar que la escoria pegajosa salga al realizar la escoriaci\u00f3n.
\n(4) Controlar de forma razonable la proporci\u00f3n entre escoria, hierro y silicio.
\n(5) Limpia a tiempo cualquier peque\u00f1a cantidad de residuos adheridos a la parte superior de la tolva de escoria caliente.
\n(6) Comprueba con cuidado si la rampa se ha deformado durante el turno.<\/p>","protected":false},"excerpt":{"rendered":"
