れている。2. Description of the Related Art Generally, glass fibers are loaded with a high-temperature molten glass into a rotor, that is, a spinner having a large number of fine holes in its side wall, and are driven to rotate at a high speed of about 200 rpm or more. Then, it is molded by being extruded from a large number of minute holes by centrifugal force. Since the glass fiber is molded under the severe conditions as described above, the spinner is required to have high temperature strength capable of withstanding high temperature and high speed rotation, particularly high temperature creep rupture strength. In addition, it is necessary to have oxidation resistance at high temperatures, and since molten glass passes through minute pores at high speed, corrosion resistance and wear resistance are also required. As an alloy satisfying such requirements, a Co-based heat-resistant alloy for spinners containing Co as a basic element is disclosed in Japanese Examined Patent Publication No.
No. 387 and the like have been proposed. This Co-based heat-resistant alloy for spinner is excellent in high-temperature strength and resistance to molten glass erosion, but has a drawback that Co is expensive and costly. There is also a problem with corrosion resistance. Therefore, Ni-base heat-resistant alloys for spinners containing Ni as a basic element have been disclosed in, for example, Japanese Patent Publication Sho 63

る。As described above, alloys for spinners are required to have high-temperature creep rupture strength, corrosion resistance to molten glass, wear resistance, etc., but Ni-base heat-resistant alloys use Ni-base as a basic element. Therefore, it has excellent resistance to molten glass erosion. Further, since it is cheaper than the cobalt type, there is an advantage that the spinner alloy can be provided at a low price. However, the conventional Ni-base heat-resistant alloy has a problem in high-temperature creep strength, and is not always satisfactory as a heat-resistant alloy for glass fiber molding spinners. Therefore, the present invention has excellent resistance to molten glass erosion and is a relatively inexpensive Ni group as a basic element,
It is an object of the present invention to provide a Ni-based heat-resistant alloy for glass fiber molding spinners, which has high high-temperature creep rupture strength.

By adding 5 to 30% by weight of Co as an alloy component, the high temperature creep rupture strength is high even under severe operating conditions such as high speed rotation while contacting molten glass under high temperature. It has been found that an alloy that is hard to break and deform can be obtained. That is, as a result of conducting research to develop an alloy having high temperature oxidation resistance, high temperature strength (high temperature creep rupture strength) and molten glass corrosion wear resistance,

When this Ni-based heat-resistant alloy is used in the manufacture of glass fiber molding spinner materials, it has excellent performance over a long period of time. I got the knowledge that it will work.

ら構成されている。BACKGROUND OF THE INVENTION In general, glass fibers are prepared by charging hot molten glass into a rotor or spinner having a large number of micropores on its side wall, and then at 2000 r.p.m. p. It is molded by being rotationally driven at a high speed of about m or more and extruded from a large number of minute holes by centrifugal force. Since the glass fiber is molded under the severe conditions as described above, the spinner is required to have high temperature strength capable of withstanding high temperature and high speed rotation, particularly high temperature creep rupture strength. In addition, it is necessary to have oxidation resistance at high temperatures, and since molten glass passes through minute pores at high speed, corrosion resistance and wear resistance are also required. As an alloy satisfying such requirements, a Co-based heat-resistant alloy for spinners containing Co as a basic element is disclosed in Japanese Examined Patent Publication No. 62-54.
I Ri has been proposed multi-number, such as No. 387. This Co-based heat-resistant alloy for spinners is excellent in high temperature strength and resistance to molten glass erosion, but has a drawback that Co is expensive and costly. There is also a problem with corrosion resistance. Therefore, Ni-base heat-resistant alloys for spinners containing Ni as a basic element have been disclosed in, for example, Japanese Patent Publication Sho 63
-64512. The composition of this Ni-base heat-resistant alloy is 0.05% to 0.50% of C, 1% by weight.
5-35% Cr, 1-7% W, 0.10-0.25
