本発明は精紡機、撚糸機等に使用する紡機用金属トラベ

。Traditionally, metal travelers for spinning machines, such as those used in spinning machines and yarn twisting machines, are generally made of hard crocodile wire, and can be used in horizontal, vertical, or
They are formed into various shapes such as conical shapes, hardened by quenching and tempering, and subjected to surface treatments such as nickel plating and chrome plating, and are used depending on their purpose.

紡出条件と操業能率向上が要求される紡績業界に於ては
、安定操業と経済的な観点から耐摩性に優れ、長寿命で
トラベラ焼けが少なく、更には、糸切れ・糸毛羽の少な
いトラベラが要求されている。However, in the recent spinning industry, which requires high productivity, high speed spinning, strict spinning conditions, and improved operational efficiency, from the viewpoint of stable operation and economics, it is necessary to use a traveler with excellent abrasion resistance and long life. There is a demand for a traveler that is less likely to burn and, furthermore, has less thread breakage and thread fuzz.
従って上記従来のトラベラでは高速運転時の耐摩耗性・
耐熱性が不十分で、トラベラ焼けが発生し、硬度が低下

問題点があった。Therefore, in the conventional traveler mentioned above, the wear resistance and
There were problems in that heat resistance was insufficient, traveler burn occurred, hardness decreased, and the above requirements were not satisfied in terms of life.

供するものである。Means for Solving Problem C] The metal traveler for spinning machines of the present invention solves the above-mentioned conventional problems, and contains CG of 6 to 1.2% and Si of 1.0%.
Below, Mn 1.0% or less, Cr 11.0-20.0%,
Mo 1.0-2.0%, VO, 05-0.6%,
The alloy steel wire, the balance of which is Fe and impurities, is hardened and then subjected to soft nitriding or nitriding to form a compound layer and a diffusion layer from the outermost surface. The present invention provides a long-life metal trapper for spinning machines with less yarn breakage and yarn fuzz, excellent toughness, wear resistance, and heat resistance.

くなる。In addition, C is an effective element that increases the hardness of quenching and tempering and contributes to improving wear resistance, but if it is less than 0.6%, the effect of wear resistance decreases, and if it exceeds 1.2%, C is an effective element that contributes to improving wear resistance. Abnormal structures such as ferrite often appear around giant carbides, which tends to cause uneven hardness, lower toughness, and poor workability.
Ｓｉは従来より溶鋼の脱酸を目的として添加されていた
もので焼戻しによる硬度が高くなるが、１．０％ を超
えると靭性が低下する。Si has traditionally been added for the purpose of deoxidizing molten steel, and increases hardness during tempering, but if it exceeds 1.0%, toughness decreases.
Ｍｎはトラベラに有害な介在物の形態を変化させ、より

するので１，０％以下がよい。A certain amount of Mn is necessary because it changes the form of inclusions that are harmful to the traveler and makes them more harmless, but since retained austenite increases during quenching and hardness decreases, it is preferably 1.0% or less.

に経済的にも好ましくなり）。Cr helps generate a stable nitride layer at the nitriding temperature, and is a carbide-forming element that improves wear resistance, heat resistance, hardenability, etc. If it is less than 11.0%, the heat resistance effect decreases, and corrosion resistance decreases. Moreover, if it exceeds 20.0%, giant carbides are generated, the toughness decreases, and the plastic workability decreases, and it is also economically unfavorable).

と経済的に好ましくない。MO is a nitride-forming element, and the addition of Mo prevents a decrease in toughness, which is an adverse effect of nitriding treatment, and improves toughness by distributing carbides finely and uniformly.
If it is less than 2.0%, the effect will be reduced, and if it exceeds 2.0%, it is economically unfavorable.
