摘要： A stirrer includes a shaft, and a plurality of stirring blades mounted on the shaft along a longitudinal direction of the shaft. The stirrer is configured to stir molten glass in a stirring vessel by causing the plurality of stirring blades to turn about the shaft in association with rotation of the shaft. The plurality of stirring blades (blade bodies) each have a through opening and a distal end portion extending along the longitudinal direction of the shaft. The plurality of stirring blades are mounted on the shaft so that, when the plurality of stirring blades turn about the shaft, the stirring blades that are closer to one end side of the shaft are delayed in phase around the shaft with respect to the stirring blades on another end side of the shaft.

摘要： In manufacturing a glass article (GR) by causing a molten glass (GM) to flow through a transfer pipe (12) and to be transferred, the transfer pipe (12) includes: a pipe end portion (14) being an end portion in a pipe axis direction; a pipe-shaped portion (15); and a joining portion (16) configured to join the pipe end portion (14) and the pipe-shaped portion (15) to each other. The pipe end portion (14) includes a flange portion (17) and a curved portion (18) extending from an inner peripheral end (17a) of the flange portion (17) toward the pipe-shaped portion (15) side and being reduced in diameter toward the pipe-shaped portion (15) side. The pipe end portion (14) is made of a material having a smaller creep rupture strength and/or a larger creep strain rate than the pipe-shaped portion (15) at 1,500° C. and 1,000 hours.

摘要： Provided is a manufacturing method for a glass article, including: a pre-heating step (S1) of heating a transfer pipe (7); and a transfer step (S4) of causing molten glass to flow through the transfer pipe (7) after the pre-heating step (S1). The transfer pipe (7) includes a main body portion (8) having a tubular shape and a flange portion (9a, 9b) formed on an end portion of the main body portion (8). The main body portion (8) is retained by a refractory (10). In the pre-heating step (S1), the main body portion (8) is heated while the flange portion (9a, 9b) is movably supported so that the flange portion (9a, 9b) is moved in accordance with extension of the main body portion (8).

摘要： A manufacturing method for a band-shaped glass includes a forming step, which forms a band-shaped glass, an annealing step, which performs an annealing treatment on the band-shaped glass, a cooling step, which cools the annealed band-shaped glass, a direction-changing step, which changes a feeding direction of the cooled band-shaped glass from a longitudinal direction to a horizontal direction, and a horizontal conveying step, which conveys the band-shaped glass in the horizontal direction while supporting the band-shaped glass at a horizontal conveyance part. In the horizontal conveying step, the band-shaped glass is conveyed in the horizontal direction while a first propulsion for driving the conveyance in the horizontal direction is provided at both sides in the width direction of the band-shaped glass by the horizontal conveyance part, the first propulsion being larger than a second propulsion provided at a center in the width direction of the band-shaped glass.

摘要： A method of manufacturing a band-shaped glass includes forming, while being drawn downward, the band-shaped glass having a thickness of 300 μm or less except both edge portions in a width direction thereof, and then changing a conveying direction of the band-shaped glass to a lateral direction so that a front surface constitutes an upper surface. The band-shaped glass is introduced to a region for changing the conveying direction under a curved state in which the front surface side thereof is concave in the width direction. The band-shaped glass in the curved state satisfies a relationship of 0>δ≧−200 mm, where δ represents a maximum separation distance with respect to an imaginary straight line connecting both the edge portions of the band-shaped glass in the width direction, provided that the maximum separation distance is positive on the front surface side of the band-shaped glass.
