- a stirring blade projects from a shaft serving as a rotating shaft.
- these glass production equipment molten glass bath, production stirrer
- a platinum material such as an oxide dispersion strengthened platinum alloy or a platinum-rhodium alloy (generally called reinforced platinum).
- reinforced platinum is the mainstream. This is because platinum materials are excellent in mechanical properties at high temperatures, particularly high temperature creep strength.
- the platinum material is chemically stable, has little erosion by molten glass, and is suitable for the production of high-quality glass.
- FIG. 6 is a diagram for explaining a manufacturing process of a general glass production stirrer.
- a rectangular plate material is prepared by rolling an alloy ingot or the like, and this is wound to join the butts at both ends to form a tube shape.
- this pipe is drawn with a draw bench or the like to produce a shaft having a predetermined size and thickness.
- a stirrer having a predetermined shape is joined to the shaft to form a stirrer.
- a stirrer for glass production is a structure that is exposed to molten glass that is viscous at high temperatures and that rotates for a long time. For this reason, the stirrer for glass production is sufficiently designed not only for the member dimensions but also for the material structure in the production process described above.
- the stirrer shaft serving as the rotating shaft is subjected to a large load that supports the weight of the stirring blade and the stress received by the stirring blade during operation at a high temperature. Therefore, it is designed with an appropriate thickness, and as described above, a high-strength material such as a platinum-based material is used and its material structure is adjusted.
- an object of the present invention is to provide a pipe that constitutes a stirrer shaft of a stirrer for producing glass with a strength higher than that of the conventional pipe and less likely to be deformed.
- the material structure has been examined in addition to the dimension design.
- the stress that the stirrer shaft receives is the viscosity of the molten glass during operation of the stirrer as well as the weight of the stirring blade. It has been considered that these stresses mainly act in the vertical direction (longitudinal direction of the stirrer shaft). From this, the conventional stirrer shaft pipe has been focused on improving the strength in the longitudinal direction. For this reason, importance is attached to the longitudinal section of the material structure, and consideration has been given to adjusting the crystal grain aspect ratio (longitudinal direction / radial direction) according to the processed structure.
- the inventors of the present invention preferably improve the strength of the stirrer shaft not only in the longitudinal direction of the pipe but also in the circumferential direction of the material structure to enhance the bidirectional crystal grain aspect ratio in a balanced manner. I thought.
- the adjustment of the crystal grain aspect ratio is generally performed by material processing.
- a crystal structure having a high aspect ratio elongated in the processing direction can be formed.
- the plate material before being formed into a pipe is produced by rolling or the like
- only the adjustment of the crystal grain aspect ratio in the longitudinal direction after the pipe machining is performed.
- the processing rate in this direction was increased. This is because, as described above, conventionally, attention has been paid only to the material structure in the longitudinal direction.
- the present inventors have adopted a multilayer structure in which a plurality of pipes are laminated with respect to the structure of the stirrer shaft pipe, and as a pipe constituting this, the crystal grain aspect ratio in both the longitudinal direction and the circumferential direction is set.

- the pipe has a multilayer structure, and at least one of the plurality of pipes constituting the multilayer structure has a crystal grain aspect ratio (longitudinal direction / radial direction) of 10 to 100 in the material structure of the longitudinal section.
- each direction (longitudinal direction, radial direction, circumferential direction, cross-sectional direction) for determining the crystal grain aspect ratio in each cross section of the pipe, it is defined as shown in FIG. .
- the present invention secures the necessary wall thickness by combining thin-walled pipes, and the number of layers is 2-5.

There is a range that has been considered in the prior art.

- the most thermal and structural load on the stirrer shaft is the outermost pipe that is in direct contact with the molten glass and to which the stirring blades and the like are joined. Therefore, it is particularly preferable to apply the pipe with the adjusted crystal grain aspect ratio to the outermost layer.
- the overall crystal grain aspect ratio is in the above-mentioned preferable range. This is because long-term durability can be ensured by having a suitable strength in the entire stirrer shaft pipe. That is, the average value of the crystal grain aspect ratio in the longitudinal direction and the circumferential direction in the pipes constituting each layer is 10 to 100 in the longitudinal section, and the average value of the crystal grain aspect ratio in the circumferential section is 5 to 100. It is preferable that The average here is a thickness weighted average considering the thickness of each layer.
- a specific calculation method is a value obtained by dividing the total value of all layers by the product of the thickness of the pipe of each layer and the crystal grain aspect ratio, and the thickness of the entire stirrer shaft pipe.

Various platinum materials (oxide dispersion type platinum alloy, platinum alloy (platinum-rhodium alloy, etc.)) are preferable. Moreover, although it is not necessary for the material of the pipe which comprises each layer to be the completely same composition, the thing of the same composition is preferable. This is because if the constituent materials of the pipes are different, there is a risk of deformation due to a difference in the amount of thermal expansion.
