    摘要： A glass fining system, multi-stage vacuum housing, and method are disclosed. The glass fining system includes a multi-stage vacuum housing comprising a first melt receipt tank configured to receive molten material, where the first melt receipt tank is disposed in a first vacuum chamber; a first refining channel configured to flow the molten material from the first melt receipt tank through a second vacuum chamber; a second melt receipt tank configured to receive the molten material from the first refining channel, where the second melt receipt tank is disposed in a third vacuum chamber; and a second refining channel configured to flow the molten material from the second melt receipt tank and through a fourth vacuum chamber; and a glass melter coupled to the multi-stage vacuum housing.

    摘要： In embodiments, a method for operating a glass manufacturing apparatus may include heating a delivery conduit with resistive windings positioned around an exterior surface of the delivery conduit, the delivery conduit extending between a mixing vessel and a delivery vessel. The method may also include injecting electric current through the delivery conduit while heating the delivery conduit with resistive windings and prior to flowing molten glass through the delivery conduit thereby increasing a temperature of the of the delivery conduit, wherein an input heat flux into the delivery conduit is greater than an output heat flux away from the delivery conduit prior to flowing molten glass through the delivery conduit.

    摘要： A vacuum melting furnace for infrared glass, includes an upper furnace body and a lower furnace body that can be connected with each other or isolated from each other. Vacuum melting of the infrared glass is achieved in the upper furnace body wherein the influence of water in the environment is eliminated. The vacuum negative pressure environments can promote separation of hydroxyl in the structure, which achieves removing of hydroxyl in the glass, and then discharging of the molten infrared glass is conducted at atmospheric pressure in the lower furnace body. By using the vacuum melting furnace for infrared glass, infrared glass with good spectrum transmission performance can be obtained with improved property stability and optical homogeneity, which facilitates the preparation and molding of large sized and special-shaped infrared glass products.
