できると共に、リングの摩耗も少なく寿命が長い紡機用
リングを提供するにある。However, in the conventional spinning ring, the spinning speed of the spinning machine is 20,000 r.p.m.
When it was used at a high speed of pm or more, the frictional resistance between the ring and the traveler increased, the frictional heat rose sharply, the traveler burned early, and was scattered, making continuous operation impossible.
The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a ring for a spinning machine which can be stably operated in an ultra-high speed rotation range and has a long wear and a small wear of the ring. .

m 以下にしたことを特徴としてなる。In order to achieve the above object, in the ring for a spinning machine of the present invention, at least a ring flange portion which comes into contact with a traveler is formed of tungsten, and a surface of a tungsten carbide layer formed by plasma carburization of 3 to 3 is formed. 8μ
m and the surface roughness of the center line average roughness Ra 0.2 μ
The feature is that it is less than m.

とするのが適当である。The surface roughness is center line average roughness Ra 0.2.
If it exceeds μm, the slidability between the ring and the traveler will deteriorate, and not only will thread breakage occur at the start, but also in the high-speed rotation range.
In the ultra-high speed range, the frictional resistance index rises sharply,
The traveler's early seizure and scattering occur, making continuous spinning impossible. Further, the thickness of the tungsten carbide layer is 3
If it is less than μm, the life of the ring is short, and if it exceeds 8 μm, cracks are likely to occur, so the range of 3 to 8 μm is appropriate.

The surface of the sliding ring flange 5 is polished by lapping to reduce the thickness of the tungsten carbide layer 7 to 5 μm.
A desired spinning machine ring was formed which was formed so as to have a surface roughness of m and a smooth surface having a center line average roughness Ra of 0.06 μm or less.

Ｂ）を用いて紡出比較テストを行なった。As shown in FIG. 2, the boundary surface between the tungsten 6 and the surface tungsten carbide layer 7 is in a state of being intruded into each other, so that peeling of the surface layer is unlikely to occur. Alternatively, only the ring flange portion may be formed of tungsten, and the other portions may be formed of another material such as iron, aluminum or resin. Next, a spinning comparison test was performed using the spinning ring obtained by the present invention (invention product A) and the spinning ring obtained by carburizing and quenching conventional low carbon steel (conventional product B). I did.

Conventional product B has been much worn since the beginning of operation, and the traveler is also often worn. Since the product A of the present invention does not peel off at the boundary surface with the ring base material and wear of the ring is small,
Stable spinning continues.
