摘要： This invention provides a molten glass conduit structure, which, without using any cooling means, can prevent the erosion of a solid heat insulating material constituting a backup of the conduit by molten glass exuded from a joint part between electrocast bricks constituting the conduit, and a vacuum defoaming apparatus using the conduit structure and a method for vacuum defoaming of molten glass using the vacuum defoaming apparatus. The molten glass conduit structure comprises a conduit and a backup provided on the periphery of the conduit. The conduit is a hollow tube having electrocast bricks provided in the longitudinal direction and circumferential direction thereof. The backup comprises a refractory layer provided on the outer side of the conduit and a heat insulating material layer provided on the outer side of the refractory layer. The refractory layer comprises a refractory brick layer comprising refractory bricks provided in the longitudinal direction and circumferential direction of the conduit. The heat insulating material layer comprises a solid refractory layer comprising solid refractories provided in the longitudinal direction and circumferential direction of the conduit. The electrocast bricks constituting the conduit and the refractory bricks constituting the refractory brick layer are selected so that, during passage of the molten glass, the site having a temperature equal to the fluidized point of the glass is located within the refractory layer.
