摘要： A vertically elongated glassmaking furnace is provided with two groups of electrodes: one group is positioned in the upper portion of the furnace and is operated to melt glass batch and to establish an upward flow of hot glass along the center of the furnace; a second group is positioned in the lower portion of the furnace and operated to slow the downward flow of molten glass through the furnace, particularly near the walls of the furnace so that all the molten glass in the lower portion of the furnace flows uniformly downwardly to discharge at a rate sufficiently slow to insure the upward escape of seeds or bubbles from the discharged glass.

摘要： A vertically elongated glassmaking furnace is provided with two groups of electrodes: one group comprises crossed pairs of electrodes positioned in the upper portion of the furnace and is operated to melt glass batch and to establish an upward flow of hot glass along the center of the furnace; a second group is positioned in the lower portion of the furnace and operated to slow the downward flow of molten glass through the furnace, particularly near the walls of the furnace so that all the molten glass in the lower portion of the furnace flows uniformly downwardly to discharge at a rate sufficiently slow to insure the upward escape of seeds or bubbles from the discharged glass. The crossed. pairs of electrodes are energized in such a way as to provide intersecting lines of current flow with the loci of intersection in the vicinity of the central vertical axis of the furnace.

摘要： Prior art high temperature electric furnaces of the type using two or more, usually three, primary electrodes positioned around an electrically conducting central outlet brought the electrodes in through a side or bottom wall of the furnace at points below the melt line causing many problems. The present invention provides a primary electrode arrangement for such melting furnaces wherein the primary electrodes do not pass through the wall or bottom of the furnace below the melt line, but instead enter the furnace over the top of the melt line and then protrude through the top surface of the melt. The primary electrodes of the present invention are provided with means for preventing wear and deterioration at the interface between the top surface of the melt and the unmelted batch and/or the oxidizing air atmosphere surrounding the top of the furnace. The improved furnace of the present invention does not require the use of a purging neutral or reducing atmosphere to protect the primary electrodes.

摘要： Method and apparatus for pre-heating a vitrifiable batch before it is introduced into a glass melting furnace. The hot gases from the furnace are used for this purpose. The batch is fed onto a support which provides apertures or openings. The support and the batch on it are heated by hot gases from the furnace until the batch is in at least a partly molten condition in which it flows through the support apertures.

摘要： The present invention provides a method of melting glass, whereby in a glass melting furnace having electrodes positioned in a plurality of levels or planes the glass is melted in a vertical passage and thereafter discharged via an outlet passage at the bottom of the furnace, while the glass stream, after its upward flow, flows vertically downwards under mechanical agitation, thereafter to flow upwards for further processing or treatment. The glass stream may be additionally heated by electrical energy during its upward flow prior to the agitation.

摘要： An all-electric glass-melting deep furnace and a method of refining and supplying glass are disclosed in which high-quality molten glass is efficiently produced in large quantity at high heat efficiency. The glass-melting deep furnace 20 has a bottom 2 and a side wall 4 constructed by piling up fireproof bricks 3 on the perimeter of the bottom 2. A height H of the side wall 4 is set to be twice or more than twice as long as an inside dimension D of the bottom 2 of the furnace. Since the furnace 20 is deep, there can be achieved a thick batch layer, a space in which glass is melted at high temperature, and a cooling area which is necessary to refine molten glass. The furnace makes it possible for the molten glass 6 to absorb fine seeds by its pressure and cooling effects that are produced when the seeds move downward to the bottom 2.
