A tempered martensite having a fine matrix structure was obtained by subjecting a carbon steel wire rod having a number (ASTM) of No. 7 (average grain size) to a heat treatment under the same conditions as the traveler for a spinning machine of the present invention (C content: 0.72%). The traveler having

られた。As a result of the spinning test, as shown in FIG. 2, when the abrasion loss is compared, the traveler for the spinning machine of the present invention has a reduced abrasion amount of about 30% as compared with the conventional traveler for the spinning machine, and the life improvement is recognized. .

は、鋼部材の機械的性質の内、結晶粒度とクリープ強度
との相関において一般には鋼の再結晶温度以上の高温環
境使用下では結晶粒が粗大なほうが細粒の場合よりもク
リープ強度が大となる。The reason why the matrix structure of the spinning traveler of the present invention is excellent in wear resistance as compared with the matrix structure of the conventional spinning traveler is that, among the mechanical properties of the steel member, the grain size and the creep strength are generally correlated. When used in a high temperature environment above the recrystallization temperature of steel, the creep strength is larger when the crystal grains are coarse than when they are fine grains.

従来の微細な焼戻しマルテンサイト基地組織に比べ、本
発明の粗大な基地組織の方が軟化抵抗性が高く、耐摩耗
性向上に効果があるからである。In the case of a traveler for spinning machines, the friction heat temperature of the traveler surface in contact with the ring is much higher than the recrystallization temperature at the crystal grain level because the frictional temperature of the traveler surface in contact with the ring slides and rubs at high speed without lubrication. Becomes Therefore, regarding the softening of the base due to frictional heat that promotes wear of the traveler,
This is because the coarse matrix structure of the present invention has higher softening resistance and is more effective in improving wear resistance than the conventional fine tempered martensite matrix structure.

性が大巾に向上し、トラベラの寿命が大巾に延長でき
る。<Effects of the Invention> Since the traveler for a spinning machine of the present invention has the above-mentioned configuration, the wear resistance is greatly improved, and the life of the traveler can be greatly extended.
しかも、トラベラの寿命延長により紡出速度の高速化が
計れるという優れた効果を有するものである。Moreover, it has an excellent effect that the spinning speed can be increased by extending the life of the traveler.
