La anchura de la ranura entre los rodillos de la boquilla de colada tiene un gran impacto en la calidad de la banda laminada en caliente. En el proceso de ajuste de la ranura entre los rodillos de la boquilla de colada, hay que tener en cuenta la expansi\u00f3n t\u00e9rmica de la propia boquilla, la expansi\u00f3n que se produce al llenarse de aluminio fundido, el radio de curvatura de la pel\u00edcula de \u00f3xido y factores relacionados con la fusi\u00f3n, como la tensi\u00f3n superficial del metal.<\/p>\n

Cuando la separaci\u00f3n entre los rodillos de la boquilla es demasiado peque\u00f1a, la distancia entre el rodillo de colada y el punta de la rueda<\/a> est\u00e1 demasiado cerca, y es f\u00e1cil que se forme escoria en la boquilla, de modo que la escoria de aluminio forma una peque\u00f1a cinta de aluminio pegajosa y irregular en la superficie del rodillo en direcci\u00f3n circunferencial, y la superficie de la banda presenta unas l\u00edneas irregulares a lo largo de su longitud; estas son las rayas longitudinales.<\/p>\n

Cuando la separaci\u00f3n entre los rodillos de la boquilla es demasiado grande, la pel\u00edcula de \u00f3xido se rompe y el \u00f3xido residual se adhiere al rodillo y es arrastrado hacia el espacio entre los rodillos de la boquilla, de modo que la pel\u00edcula de \u00f3xido queda aprisionada entre ellos, lo que provoca una microcompresi\u00f3n local de la boquilla de colada en ese punto, dando lugar a una distribuci\u00f3n no homog\u00e9nea de la masa fundida y a la formaci\u00f3n de escoria pegajosa, de modo que la velocidad de solidificaci\u00f3n de la superficie de la banda sufrir\u00e1 cambios peri\u00f3dicos, el espaciado entre dendritas tambi\u00e9n experimentar\u00e1 cambios peri\u00f3dicos y aparecer\u00e1n rayas longitudinales. Por lo tanto, un ajuste razonable de la holgura de la boquilla desempe\u00f1a un papel fundamental en la calidad del producto.<\/p>\n

\"Holgura<\/p>\n

El aluminio fundido forma una fina pel\u00edcula de \u00f3xido en el punto de contacto de la boquilla. La pel\u00edcula de \u00f3xido tiene forma de arco. Dado que la superficie del l\u00edquido es curva y est\u00e1 abierta, la tensi\u00f3n superficial del l\u00edquido ejerce una cierta fuerza sobre el metal l\u00edquido para garantizar que este no se escape por el hueco entre los rodillos de la boquilla. Del mismo modo, el metal fundido ejerce una fuerza de reacci\u00f3n sobre la pel\u00edcula de \u00f3xido, que corresponde a la presi\u00f3n est\u00e1tica de la superficie del l\u00edquido del dep\u00f3sito delantero y que act\u00faa sobre la superficie del l\u00edquido a trav\u00e9s de la transferencia del mismo. Gracias a la interacci\u00f3n entre la tensi\u00f3n superficial de la pel\u00edcula de \u00f3xido y la presi\u00f3n est\u00e1tica del metal l\u00edquido en el dep\u00f3sito delantero, el proceso de colada y laminaci\u00f3n alcanza el equilibrio.<\/p>","protected":false},"excerpt":{"rendered":"
