摘要： A method for controlling the foam produced when a molten material encounters reduced pressure in a vacuum chamber includes passing the molten material through an aging zone in the vacuum chamber in which the molten material is allowed to drain from between the bubbles of the foam and then collapsing the bubbles of the drained foam.

摘要： An electric melting furnace is described for melting high electrical resistivity glass, such as E-glass, within a melting chamber surrounded by a relatively low electrically resistivity refractory, such as chromic oxide refractory, by utilizing interconnected peripherally positioned batch electrodes at substantially the same potential as the chromic oxide walls and centrally positioned electrodes which are immersed a greater distance than the batch electrodes. A quiescent zone is formed adjacent a lower portion of the melting chamber and the batch blanket and effective hydrostatic head of the molten bath are adjusted by controlling the immersion of the batch electrodes within the molten bath.

摘要： A tubing system for conveying a molten material through a vacuum housing includes a tubing having a plurality of convolutions which compress as the tubing expands. A plurality of projections disposed along a length of the tubing carries the electrical current which heats the tubing. A plurality of refractory insulation bricks are stacked between the projections. A first seal flange is coupled to an inlet end of the tubing, and a second seal flange is coupled to an outlet end of the tubing. Each seal flange includes a metal seal ring which is adapted to be coupled to the base of the vacuum housing so as to make a sealed contact with the base of the vacuum housing. Each seal flange also includes a refractory seal block which transfers the expansion force of the tubing to the metal seal ring and, thereby, causes the convolutions to compress.

摘要： Process and apparatus are disclosed for delivering molten thermoplastic material from one chamber to another through a throat in a refractory wall separating said chambers. A refractory metal conduit is positioned within said refractory throat below the level of the floor of said chambers, and standpipes at each end of said conduit extending above the level of said floors, create stagnant thermoplastic material about the conduit so as to prevent corrosion products from flowing away from about the conduit and thereby also preventing fresh thermoplastic from replacing it. The stagnant material becomes enriched with corrosion products, which with the absence of flow retards further corrosion of the refractory about the conduit.

摘要： A glass melting furnace is disclosed having a refractory melting vessel provided with a protective liner formed of an oxidizable refractory metal such as molybdenum, wherein the liner projects upwardly within a molten bath contained within the vessel and through its fusion line into a batch blanket retained thereabove which is low in carbonates. The upper end of the liner is provided with a seal to prevent the flow of batch material between the liner and the refractory vessel and thereby prevent contamination of material behind the liner and reduce corrosion of the refractory vessel.
