Abstract: A method of controlling a flowrate of molten material at a downstream location in a glass manufacturing process can include mixing the molten material at an upstream location positioned upstream from the downstream location relative to a flow direction of the molten material with a shaft including a plurality of protrusions. The method can also include measuring a torque of the shaft, measuring a level of the molten material at the upstream location, and calculating a viscosity of the molten material at the upstream location based on the measured torque and the measured level. In addition, the method can include estimating the flowrate based on the calculated viscosity, and controlling the flowrate at the downstream location based on the estimated flowrate.

Abstract: An exhaust conduit for a glass melt system includes a corrosion resistant refractory conduit material, such as a conduit material including zirconia. The conduit can extend through a relatively dense refractory block material, such as a refractory block comprising alumina. The exhaust conduit can exhibit improved corrosion resistance in processing a variety of glass melt compositions.

Abstract: An electrically boosted refractory melting vessel including a back wall, a first side wall, a second side wall, a front wall and a bottom wall, the melting vessel comprising a longitudinal center line extending from the back wall to the front wall and an overall width orthogonal to the longitudinal center line extending between an inside surface of the first side wall and an inside surface of the second side wall. The melting vessel also includes a length L between the back wall and the front wall, and a width W between the first side wall and the second side wall orthogonal to the center line. A plurality of electrodes extend into an interior of the melting vessel through a bottom wall of the melting vessel, and L/W is in a range from about 2.0 to about 2.4.

Abstract: Apparatuses for interfacing with an electrode provided with a melting furnace including a vessel and an electrode. In some embodiments, a support assembly (50) supports the electrode outside of the vessel, and includes a cart (102) or similar apparatus that permits or facilitates selective vertical movement of the electrode and selective transverse movement of the electrode. In some embodiments, a push assembly (52) interfaces with a rear face of the electrode outside of the vessel, and is operable to apply a pushing force onto the rear face. The push assembly can include one or more tracks (e.g., threaded screw) that supports a body between opposing arms of a fixed frame. The body can translate along the tracks to apply a pushing force onto the electrode.

Abstract: A melting apparatus is disclosed, the melting apparatus including a melting vessel with a back wall, a front wall, a first side wall, a second side wall and a longitudinal centerline extending therebetween and a width between the first and second side walls orthogonal to the centerline. The melting vessel further includes a first feed screw including a first axis of rotation and a second feed screw including a second axis of rotation, the first axis of rotation positioned between the longitudinal centerline and the first side wall and the second axis of rotation positioned between the longitudinal centerline and the second side wall. The positions of either one or both the first and second axes of rotation are located from a respective side wall a distance that is equal to or less than about 15% of the width of the melting vessel.
