なるという欠点がある。 However, in recent years, high production and high speed spinning have been carried out, and under harsh operating conditions, such rings have insufficient wear resistance against the traveler and wear out prematurely, making the traveler unstable and causing yarn breakage. There are drawbacks such as frequent fuzz formation, early seizure of the traveler, scattering, and shortened ring life.

のである。Means for Solving the Problems The present invention solves the above problems, and includes C0.08~0.90, Cr10~28, Ni37 at least in weight%.
By processing a heat-resistant alloy steel material containing the following into a predetermined ring shape, under conditions of high production and high speed spinning, there is less yarn breakage and yarn fuzz, and prevents premature seizing of the traveler and scattering. To provide a ring for a spinning machine which has excellent wear resistance and whose structure does not easily fatigue even under severe sliding conditions with a traveler.
以下に本発明の数値限定理由を述べる。 The reasons for limiting the numerical values of the present invention will be described below.
Ｃは鋼材の基地硬さを高め、Crと結合して炭
化物を形成して耐摩耗性を向上させる。このため
0.08％以上が必要であり、0.90％を越えると加工
性が悪くなる。 C increases the base hardness of steel, combines with Cr to form carbides, and improves wear resistance. For this reason
A content of 0.08% or more is required, and if it exceeds 0.90%, workability will deteriorate.
CrはＣと結合して硬い炭化物を形成し、耐摩
耗性、耐焼付性を高め、かつ耐熱ヘタリ性を向上

％を越えると焼入れ時に十分な硬さが得られ難く
なり、靭性が低下する。 Cr is required to be at least 10% or more because it combines with C to form hard carbides and improves wear resistance, seizure resistance, and heat set resistance.
%, it becomes difficult to obtain sufficient hardness during quenching, and toughness decreases.
Niは靭性の向上に役立つ、37％を越えると耐
摩耗性、耐熱ヘタリ性に悪影響を及ぼす。 Ni is useful for improving toughness, but if it exceeds 37%, it will have a negative effect on wear resistance and heat resistance.
以下本発明の１実施例を図面に基づいて説明す
る。 An embodiment of the present invention will be described below based on the drawings.

A martensitic heat-resistant alloy steel containing the following materials was machined into a predetermined ring shape, and then quenched and tempered to form a ring with excellent wear resistance.
上記本発明の紡機用リングを従来リングと比較
のため次に示す紡出条件により紡出テストを行つ
た。 In order to compare the ring for a spinning machine according to the present invention with a conventional ring, a spinning test was conducted under the following spinning conditions.
糸：エステル／綿 40′S
リング：3.2mmフランジ 41mm〓
トラベラ：ZSB／hf No.９／０
スピンドル回転数：20000r.p.m
