【発明の詳細な説明】
本発明はレーヨン系、アクリル系繊維紡糸ノズル用材料
として使用する合金の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in alloys used as materials for rayon-based and acrylic-based fiber spinning nozzles.
従来、上述の如きレーヨン系、アクリル系繊維紡糸ノズ
ル用材料としては金−白金（３０〜゛ｓｏ％）合金が多
用されている。この合金は１時効処理前は薄板、絞）、

という欠点があった。Conventionally, gold-platinum (30 to 50%) alloy has been widely used as a material for the above-mentioned rayon-based and acrylic-based fiber spinning nozzles. This alloy is thin sheet (drawn) before aging treatment.
Although it has excellent pore processability, it has low abrasion resistance and pressure resistance after aging treatment, so when used as a finished product, the corner on the spun side of the spout hole may be reduced or damaged due to wear. ] It had the disadvantage of doing so.
本発明は上記の欠点を解消せんが為になさねたものであ
り、加工性、耐摩耗性、耐圧力に優れた紡糸ノズル用合
金を提供せんとするものである。The present invention has been made to eliminate the above-mentioned drawbacks, and it is an object of the present invention to provide an alloy for spinning nozzles that is excellent in processability, wear resistance, and pressure resistance.
本発明による紡糸ノズル用合金の１つは白金８Ｏ−９８
Ｗ１０．すず２〜２０−よシなる時効硬化性を具備した
ものでもう１つは白金６５〜９５−すず２〜２０ Ｗ１
０ｙ残部パラジウムよシなる時効硬化性を具備したもの
である。One of the alloys for spinning nozzles according to the present invention is platinum 8O-98.
W10. The other one is platinum 65-95-tin 2-20 W1, which has good age hardening properties.
It has age hardening properties with the remainder being palladium.
本発明による紡糸ノズル用合金に於いて、すすを添加し
た理由は白金−すすの２元状態図からも明らかなように
すすは白金に対して１３６５℃で最大同浴量ｓ ”、４
を示し、その固ｆｇ度は温度下降と共に漸次減少し、
固溶体領域まで加熱し、急冷する溶体化処理を行った稜
、適当な温度で時効させると著しい時効硬化性を現わす
為である。The reason why soot is added to the alloy for spinning nozzles according to the present invention is that, as is clear from the platinum-soot binary phase diagram, soot has a maximum bath amount s'', 4 at 1365°C relative to platinum.
, and its hardness gradually decreases as the temperature decreases,
This is because the edge, which has been subjected to solution treatment in which it is heated to a solid solution region and rapidly cooled, exhibits remarkable age hardening properties when aged at an appropriate temperature.
その添加量が２−未満では、硬さの改善が殆んどなく、
２０−を超えると白金とすすの金属間化合物の量が多く
なシ、加工性が悪くなるからである６また、パラジウム
を添加した理由は、すすの添加による耐酸性、耐アルカ
リ性の低下を防止するためである。If the amount added is less than 2, there is almost no improvement in hardness,
If it exceeds 20-, the amount of intermetallic compounds of platinum and soot will be large and the processability will deteriorate.6Also, the reason for adding palladium is to prevent the decrease in acid resistance and alkali resistance due to the addition of soot. This is to do so.
以下、采発明による紡糸ノズル用合金の効果を明瞭なら
しめる為に実施例及び従来例について述べる。Examples and conventional examples will be described below in order to clarify the effects of the alloy for spinning nozzles according to the invention.

耐摩耗性について試験したところ第２表のような結果を
得た。When the wear resistance was tested, the results shown in Table 2 were obtained.
第 １ 表
第 ２ 表

後の吐出孔のかどの曲率半径によって行なっ念。Table 1 Table 2 The wear resistance test was conducted using a spinning nozzle with 70 discharge holes with an inner diameter of 501 pm and a corner radius of curvature of 5 pm after spinning rayon fiber for 2000 hours at a pressure of ttOKf/cd. By doing this.
上記で明らかなように本発明による紡糸ノズル用合金は
従来の紡糸ノズル用合金に比し時効硬化後の硬さが著し
く優れ、耐摩耗性についても優れていることが判る。As is clear from the above, the alloy for spinning nozzles according to the present invention has significantly superior hardness after age hardening and is also superior in wear resistance compared to conventional alloys for spinning nozzles.
以上詳記した通シ、本発明による紡糸ノズル用合金は加

期的なものと言える。As detailed above, the alloy for spinning nozzles according to the present invention has extremely excellent workability, mechanical strength, and wear resistance.
It can be said to be a revolutionary product that can replace conventional alloys for spinning nozzles.
