Abstract

Procedimiento y dispositivo de accionamiento de un crisol de colada repetitiva a baja presión en moldes de arena ciegos, según el cual, después de cada colada, solo se hace descender el líquido en el tubo de colada hasta un nivel igual o aproximadamente igual a un nivel predeterminado constante próximo de la salida de este tubo, procedimiento caracterizado porque se mide directamente el nivel del líquido en el tubo y la presión de gas motor que reina en el crisol, y se comienza la admisión y el escape del gas motor en función de estas medidas, de modo a respetar para todas las coladas un tiempo de subida de presión y un tiempo de descenso de la misma predeterminados prácticamente constantes.
