Abstract

Se proporcionan antecrisoles que crean una temperatura sustancialmente homogénea a materiales formadores de vidrio fundido a través de la posición terminal. Se puede utilizar una cavidad (22) de gas, un vertedero (23), un bloque refractario (32), un elemento (34) de calentamiento en el antecrisol (25, 30, 40, 50) para reducir un gradiente de temperatura de los materiales formadores de vidrio fundido a través de la posición terminal (21). La reducción de la diferencia de temperatura del material formador de vidrio fundido a través de la posición terminal permite propiedades físicas y químicas mejoradas de las fibras de vidrio y los productos terminales formados a partir de las fibras de vidrio. Además, una reducción en el gradiente de temperatura a través de la posición terminal produce una fibra de vidrio más homogénea y un producto de vidrio más homogéneo. Adicionalmente, una reducción en la proporción de corte se presenta cuando el material formador de vidrio fundido tiene una temperatura que es sustancialmente la misma a través de la posición terminal, lo que da por resultado una reducción en la ruptura de fibras de vidrio y un incremento en la eficiencia de fabricación.
