ブツシングに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to bushings for producing long glass fibers and other mineral fibers. More particularly, the present invention relates to an improved bushing having a floor surface having a large number of small holes to provide a linear flow of molten glass, the bushing being protected from deformation even when the floor surface is exposed to high temperatures for long periods of time.

を惹きおこす。 Bushings used to produce long glass fibers are exposed to high temperatures of around 1200°C for long periods of time. As a result, the floor surface made of platinum or platinum alloy and having a large number of small holes is economically deformed, causing the floor surface to gradually sag, causing thread breakage or variations in fiber thickness.

形防止対策が益々重要になつてきている。 In recent years, larger bushings with as many as 2,000 to 4,000 small holes have come into use, and the deformation of the floor surface as described above has become that much more important, making measures to prevent this deformation increasingly important. .

る。 Conventionally, as a measure to prevent such deformation, for example, bushings (see US Pat. No. 3,905,790, in particular, (See Figure 2 and Column 15, column 4), or bushings with reinforced pipes that allow water to flow inside and be cooled on the outside or lower surface of the floor surface with many small holes (Special Publication No. 44-2513). (see official gazette), etc. are known.

れの原因となるなどの改良されるべき点がある。 However, in the former type of bushing, the reinforcing horizontal bar is made of platinum or a platinum alloy, and therefore, if exposed to high temperatures for a long period of time, the bushing itself deforms in the same way as the floor surface, making it difficult to provide sufficient reinforcement. In particular, large bushings require a large number of reinforcing crossbars, which is therefore economically undesirable. In addition, with the latter type of bushing, it is not possible to place small holes in the area where the reinforcing pipe is arranged, so the floor area of the bushing needs to be increased accordingly, and it is difficult to control the temperature around the area where the reinforcing pipe is arranged, making the floor area difficult to control. There are some issues that need to be improved, such as it being difficult to maintain a uniform temperature distribution on the surface, or the airflow supplied to the lower surface of the floor hitting the reinforcing pipe and causing the airflow to become turbulent, causing thread breakage.

The bushing of the present invention illustrated in FIG. 1 further includes a support 6 fixed to the side wall 4 and a hanging member 7 connecting the support 6 and the floor 2. The support 6 has a ceramic core coated with platinum or a platinum alloy. The ceramic core material is
It is made of a material that does not soften or melt depending on the temperature of the molten glass. Moreover, the support body 6 is loaded with the support body 6 through the hanging member 7 . It is necessary that the floor surface 2 has sufficient strength to resist the force that tends to deform downward. Such strength is substantially provided by the ceramic core. The support body 6 is preferably fixedly installed through the side wall 4 as shown in FIGS. 1 and 2. The materials for such ceramic core materials are:
For example, alumina, zirconia, chromium oxide,
Metal oxides having sufficient rigidity at high temperatures, such as ZrO 2 and SiO 2 , silicon nitride, silicon carbide, boron nitride, and aluminum nitride can be used. The ceramic core material is coated with platinum or a platinum alloy and is mechanically and chemically (reacted) protected from the molten glass so that it does not come into direct contact with the molten glass. A ceramic core material may be directly coated with platinum or a platinum alloy to serve as a support.
Alternatively, a ceramic core material may be coated with a refractory metal oxide, such as ThO 2 or BeO, which does not easily contaminate platinum, and then platinum or a platinum alloy may be coated thereon to serve as a support.

That is, the bushing in the state shown in FIG. 1 or 2 is attached to the lower part of the forehearth. The forehearth and glass melting furnace are not shown in FIGS. 1, 2, and 3. Also, without the use of a separate forehearth glass melting furnace, the bushing of the present invention can be integrally connected to a melting apparatus for remelting marble-shaped or other glass. The molten glass fed to the bushing from the forehearth or melting device forms glass fibers which are extruded through the small holes 3.

できる。 The structure of the bushing of the present invention is suitably applied to bushings having a large number of small holes and therefore having a large floor area. In a bushing with a large floor area, a relatively central portion of the large floor area is susceptible to thermal deformation. Therefore, a bushing according to the invention having a particularly large floor area can have a relatively high density of hanging elements in the central part of the floor surface, which is located at a large distance from the side walls.

きる。 In the bushing of the present invention, the support is fixed to and supported by the side wall. The support of the support body may be partly shared by the outside by extending the support body through the side wall to the outside and simultaneously supporting the support body at the extended portion.

なる。 According to the bushing of the present invention, not only is deformation of the bushing reliably prevented, but also the effective floor area of the bushing can be increased compared to, for example, a conventional bushing that uses a reinforcing pipe on the bottom surface of the bushing. It can be made compact and maintains a good temperature distribution on the floor surface of the bushing, and since there is no extra equipment on the bottom surface of the bushing, the airflow supplied to the bottom surface of the bushing is not disturbed and thread breakage is prevented. becomes that much less.

た。 Specifically, for example, a bushing with 2000 small holes on the floor (height approx. 12cm x width approx. 40cm, floor area approx.
480cm 2 ). With a bushing (one type of conventionally known reinforcing bushing) in which a single reinforcing bar made of platinum with a T-shaped cross section is fixed in the vertical direction inside the floor surface, the floor surface can be improved by continuous operation for about two months. It became necessary to correct the deformation, but the bushing of the present invention (4 horizontal support rods, 5 thin wires suspended from each support rod) required correction of the floor surface even after the 6th month of continuous operation. No deformation occurred.

In order to provide several small holes, the floor area becomes approximately 550 cm 2 (approximately 5% more than the floor area of the bushing of the present invention).
Furthermore, the temperature at the bottom of the floor showed a variation of about 30 to 60°C (the temperature variation in the bushing of the present invention was about 10 to 20°C). In addition, in this conventional bushing, the yarn discharged from the small hole adjacent to the reinforcing pipe was more likely to be cut than from other parts. It was thought that the airflow supplied to the lower surface of the floor collided with the reinforcing pipe, creating a swirling airflow and causing thread breakage.
