題が生ずる。[Prior Art] A bushing for fiber forming has a number of nozzles protruding from the bottom of a boat-shaped container made of Pt or Pt alloy into which a molten fiber raw material is placed, and the molten glass raw material flows out from the nozzles. The fiber-forming bushing is configured so that the tip of the fiber-forming bushing has a fiber shape. The method of attaching the nozzle to the bottom plate of such a fiber-forming bushing is described in Japanese Patent Publication No. 45-2329 and Japanese Patent Publication No. 59-1.
There is one as shown in No. 25265. That is,
As shown in FIG. 4, a rivet-shaped nozzle element 4 is formed by integrating a foot portion 1 and a truncated conical portion 3 having a stepped portion forming a large-diameter surface 2 following the foot portion 1. The foot part 1 is locked into a hole 6 with a diameter of about 2 mm drilled in the bottom plate 5 as shown in Fig. At this time, as shown in FIG. 6, the washer 7 can be used alone, aligned as shown in the two rows on the left in FIG. 7, and locked as shown in FIG. 8, or As shown in FIG. 9, the continuous sheet 7 is aligned as shown in FIG. 10 and locked as shown in FIG. After that, the bottom plate 5 and the nozzle elements 4 are heated to melt the washer 7 and become a whole, and then a hole is made in the center of each nozzle element 4 as shown in FIG. 12 to form fibers. It is used as a bushing. However, according to such conventional technology, when locking the nozzle element 4 to the bottom plate 5, the tip of the foot part 1 of the nozzle element 4 is fixed by caulking, but when performing this caulking, the nozzle element 4 and bottom plate 5
Since the washer 7 is interposed between them, the accuracy of caulking is poor, resulting in variations in the degree of close contact between the washer 7, the nozzle element 4, and the bottom plate 5, and deviations in the center position of the nozzle element 4. As a result, the alignment of the nozzle element 4 after heat welding becomes poor, and uneven thickness occurs at the tip of the nozzle element 4 during drilling of the nozzle element 4, which is performed later, which causes inconvenience when forming glass fibers when actually used. result. In addition, since the washer 7 is arranged around the hole in the bottom plate, during heat welding, the molten Pt solder flows around the hole in the bottom plate, and does not enter the hole and is welded in the thickness direction. Insufficient portions are likely to occur, resulting in problems with durability.

By melting the Pt solder and fixing the nozzle element by welding, the nozzle element can be accurately positioned in the hole drilled in the bottom plate, and the legs can be firmly fixed.

FIG. 1 is a perspective view of the nozzle element, FIG. 2 is a perspective view of a composite wire, and FIG. 3 is a cross-sectional view of the nozzle element fitted into the hole in the bottom plate.
The core material 8 is made of Pt alloy wire, with an inner diameter of 15.1 mm and a wall thickness of 0.
After fitting and tightly fitting the 8 mm Pt pipe 9, 10
Diffusion treatment was performed at 00℃, this composite material was wire-drawn,
A composite wire 10 having a diameter of 2 mm as shown in FIG. 2 was obtained. Next, this composite wire 10 is processed into a header to form a nozzle element 12 having a Pt brazing layer 11 on the surface layer as shown in FIG. After the tips of the legs 13 are caulked and locked, the area around the nozzle element 12 is heated with a burner or the like to melt the Pt brazing layer on the surface and make the entire body into one piece. Thereafter, a hole was made in the center of each nozzle element 12 to form a fiber-forming bushing.
