本発明は精紡機、撚糸機等に使用する紡機用金属トラベ
ラに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a metal traveler for spinning machines used in spinning machines, yarn twisting machines, and the like.

されている。Traditionally, metal travelers for spinning machines have generally been made of hard steel wire rods, which have been formed into various shapes such as horizontal, vertical, and conical, and have been hardened by quenching and tempering, and have been subjected to surface treatments such as nickel plating and chrome plating. It is used depending on the purpose.
ところで、最近の高生産、高速紡出という厳しい紡出条
件と操業能率の向上とが要求される紡績業界において、
安定操業と経済性の点から耐摩耗性に優れ、長寿命で、
かつトラベラ焼けが少なく、更には糸切れ、糸毛羽の発
生が少々いトラベラが要求されている。By the way, in the recent spinning industry, which requires strict spinning conditions such as high production and high speed spinning, as well as improved operational efficiency,
In terms of stable operation and economic efficiency, it has excellent wear resistance and long life.
In addition, there is a demand for a traveler that has less traveler burn, and furthermore, less yarn breakage and yarn fuzz.
しかるに、従来の硬鋼線材から成るトラベラは、高速運
転時の耐摩耗性、耐熱性が不十分であるため、トラベラ
焼けが発生し、硬度が低下し、寿命の点で問題があった
。However, conventional travelers made of hard steel wire rods have insufficient wear resistance and heat resistance during high-speed operation, resulting in traveler burns, reduced hardness, and shortened service life.
本発明の目的は、上記従来の問題点に鑑みてなしたもの
で、高生産、高速紡出の厳しい紡出条件下において、糸
切れ、糸毛羽の発生が少々く、靭性、耐摩耗性及び耐熱

にある。The object of the present invention has been made in view of the above-mentioned conventional problems, and aims to reduce the occurrence of yarn breakage and yarn fluff under severe spinning conditions of high production and high speed spinning, and to improve toughness, abrasion resistance and To provide a metal toe 2 for a spinning machine with excellent heat resistance and long life.

る。In order to achieve the above object, the metal traveler for a spinning machine of the present invention has c: o, o O ~ 1.111 o! t%,
Cr: By quenching and tempering, a martensitic structure is formed in which single-spheroidal 〇r, V double carbides are dispersed, and the product hardness is Hv 650 to 750.

ステナイトの増加により、硬さむらや硬さの低下が生じ
易く有害となり、０．９０〜Ｌ２０重量％が好ましく、
０゜９５〜１．１０重量％の範囲が最適である。C is an element that is effective in increasing quenching and tempering hardness and improving wear resistance, and the higher the carbon content, the more effective it is, but if the content is less than 0.90% by weight, the wear resistance effect decreases. ,
If it exceeds 1.80% by weight, hardenability decreases and residual austenite increases, which tends to cause uneven hardness and decrease in hardness, which is harmful, so 0.90 to L20% by weight is preferable.
A range of 0.95 to 1.10% by weight is optimal.

の範囲が最適である。Further, Cr is a carbide-forming element and is an effective element for improving wear resistance and heat resistance. If the Cr content is less than 1.60% by weight, there will be no effect, and if it exceeds 1.60% by weight, the heat resistance will improve, but the plastic workability and toughness will noticeably deteriorate, and the traveler will not be as effective. In order to impart the necessary toughness, a high temperature tempering treatment is required, and as a result, the tri-2 base hardness is greatly reduced, making it impossible to achieve the desired improvement in wear resistance, which is undesirable. The above Cr is 0.20 to 1
．． 60% by weight is preferred, and a range of 0.20 to 0.50% by weight is optimal.

ない。Next, ■ is a carbide-forming element like Cr, and is an element effective in improving wear resistance and heat resistance, and is also effective in improving toughness, but it is not effective when the V content is less than 0.055 weight. If it exceeds 0.50% by weight, heat resistance will improve, but plastic workability and toughness will decrease, which is not preferable.

The following is suitable, and possibly Si is 0.15 to α2

化抵抗に優れていることが判明した。The relationship between the frictional heat temperature of the traveler caused by friction between the travelers and the product hardness was determined using heating temperature (uniform heating maintained at a constant temperature) as a substitute for the frictional heat temperature.Product A of the present invention and conventional product B% This shows the test results for C. As is clear from this figure, the product of the present invention was found to be superior in thermal softening resistance compared to the conventional product.

FIG. 4 shows the correlation between high-temperature hardness (substitute property for thermal softening resistance) and toughness of travelers with different contents of cr■. That is, Figure @5 is c
