本発明は、各種機械機器や構造体における振動と騒音

鋼とその製法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vibration-proofing steel having a large vibration damping ability suitable for suppressing vibration and noise in various mechanical devices and structures, and a method for manufacturing the same.
最近、騒音振動問題がますます深刻化しつつあり、そ

冷間加工が困難で、実用性に乏しい等の欠点がある。
また、従来使用されている軟鋼は冷間圧延性やプレス加
工性は良好であるが、強度が低く、減衰能も小さい。Recently, noise and vibration problems have become more and more serious, and it has been pointed out that it is necessary to reduce vibrations as much as possible at their sources. For this purpose, it is necessary for the member itself to be made of a material that has a high vibration damping ability, and it is not possible to simply use rubber, plastics, or a combination of these and metal materials to dampen vibrations. In many cases, requirements such as strength are not met. Under such circumstances,
A metal material with excellent vibration damping ability and strength is desired, and Mn-C
U alloy, Mg alloy, Fe-C-Si cast iron, etc. have been developed. However, Mn-Cu alloy shows high damping capacity only in a narrow temperature range around room temperature, Mg alloy has low strength, and Fe-C-Si cast iron cannot be processed by cold rolling or press working. It has drawbacks such as being difficult and lacking in practicality.
Furthermore, conventionally used mild steel has good cold rollability and press workability, but has low strength and low damping capacity.

を有する防振鋼が提供される。The present invention provides a material that is inexpensive and has excellent vibration damping ability.In particular, even if the vibration damping ability is increased, the mechanical properties and workability are good, and it can be used as a vibration-isolating machine material or a structural material. We provide anti-vibration steel that exhibits unprecedented effects. In other words, the present inventors found that in steel with excellent workability, C is harmful to vibration-proofing properties, and Si
, Mn is harmful to vibration damping properties above a certain limit.
l has almost no effect on vibration isolation, and a trace amount of N
The present invention was completed by discovering that the addition of at least one of B, Zr, V, Ta, and Hf is effective in improving vibration damping properties. According to the invention, a steel containing essentially Fe and unavoidable manufacturing impurities and up to 2% Si) up to 1% Mn and up to 3% C, with no more than 0.1% C and 3-40% Cr<150.02-1% Nb, Zr

方法か提供される。Further, according to the present invention, the steel essentially contains Fe and unavoidable impurities during manufacturing, up to 2% Si, up to 1% Mn, and up to 3% Al, and has a carbon content of 0.1% or less. Toshi, 3
~40% Cr<150.02~1% Nb, Zr, V
, Ta, Hf, etc. In a manufacturing method in which steel containing one or more of Ta and Hf is made into a hot rolled steel strip and then cold rolled and annealed (once or more), the cold rolling before the final annealing is carried out 2 to 3 times. Provided is a method for producing a vibration-proof steel characterized by having a high vibration damping ability by subjecting the steel to a cold rolling rate of 15% and final annealing at 750 to 950°C.
本発明の防振鋼は強度、耐高温酸化性にも優れている。
本発明鋼の組成が上記のように■定される理由は次の通
りである。The anti-vibration steel of the present invention also has excellent strength and high temperature oxidation resistance.
The reason why the composition of the steel of the present invention is determined as described above is as follows.
本発明においてはＣｒは必須元素てあり、良好な耐食性
を有する高減衰能の鋼を得るためには３％を越える量が
必要である。In the present invention, Cr is an essential element, and in order to obtain a high damping capacity steel with good corrosion resistance, an amount exceeding 3% is required.
また、Ｃｒが４０％を越えるともろくなり、また、製造
がきわめて困難となることにより、好ましいＣｒ含有範
囲は３〜３０％てあり、最も好ましい範囲は７〜２５％
てある。Ｎｂ，Ｚｒ，Ｖ，Ｔａ，Ｈｆの微量の添加の効
果は０．０２％程度より現われるが、１％を越えるとか
えつて振動減衰能が低下し、また表面肌が不良になり製
造も困難になり、さらに経済的にも不利になる。Moreover, if Cr exceeds 40%, it becomes brittle and production becomes extremely difficult, so the preferred Cr content range is 3 to 30%, and the most preferred range is 7 to 25%.
There is. The effect of adding small amounts of Nb, Zr, V, Ta, and Hf becomes apparent from about 0.02%, but if it exceeds 1%, the vibration damping ability deteriorates, and the surface texture becomes poor, making manufacturing difficult. This will make it even more economically disadvantageous.
より好ましい範囲は０．０５〜０．５％てあり、もつと
も好ましい範囲は０．１〜０．４％てある。通常これら
の元素のうちＴａやＨｆが単独で用いられることは無い
であろうが、Ｎｂ，Ｚｒの随伴元素として存在の可能性
があり、また均等物てある。Ｃは鋼の振動減衰能に極め
て有害であり、その含有量は０．１％以下に抑える必要
があることがわかつた。A more preferable range is 0.05 to 0.5%, and an even more preferable range is 0.1 to 0.4%. Of these elements, Ta and Hf are not normally used alone, but they may exist as accompanying elements of Nb and Zr, and equivalents are also available. It has been found that C is extremely harmful to the vibration damping ability of steel, and that its content needs to be suppressed to 0.1% or less.
Ｓｉは脱酸剤として使用されて０．０１％以上鋼中に残
留し、それは望ましいことであるが、２％を越えると鋼
の振動減衰能を低下させる。Si is used as a deoxidizer and remains in the steel above 0.01%, which is desirable, but above 2% it reduces the vibration damping ability of the steel.
Ｓｉのより好ましい含有量は０．１〜１．３％であり最
も好ましい範囲は０．２〜０６％てある。Ｍｎも脱酸剤
、脱硫剤として使用され、鋼中に残るＭｎは強度の向上
に有効で、多量に添加されることもあるが、振動減衰能
に関しては有害であり、１％以下に抑えなければならな
い。A more preferable Si content is 0.1 to 1.3%, and the most preferable range is 0.2 to 06%. Mn is also used as a deoxidizing agent and desulfurizing agent, and Mn remaining in steel is effective in improving strength and is sometimes added in large amounts, but it is harmful to vibration damping ability and must be kept below 1%. Must be.
その理由はＭｎがオーステナイト形成元素であるからで
あろう。そのより好ましい含有量範囲は０．１〜０．６
％、もつとも好ましい範囲は０．２〜０．４％である。
Ａ１は振動減衰能に直接影響しないと見られるが、脱酸
剤として使用されるものてあり、また、その添加は鋼の
機械的強度と耐高温酸化性の増強に有効である。しかし
３％を越えて含有させることは表面性状の劣化をきたす
。より好ましい含有量範囲は０．０１〜１．５％であり
もつとも好ましい範囲は０．０１〜１％である。不純物
のうち、Ｐ，Ｓに関しては今日の製鋼技術で混入して来
る量（０．０１〜０．０５％）は本発明鋼の振動減衰能
に影響を与えない。The reason may be that Mn is an austenite forming element. Its more preferable content range is 0.1 to 0.6
%, the most preferred range is 0.2 to 0.4%.
Although A1 does not seem to directly affect the vibration damping ability, it is used as a deoxidizing agent, and its addition is effective in increasing the mechanical strength and high temperature oxidation resistance of steel. However, if the content exceeds 3%, the surface quality will deteriorate. A more preferable content range is 0.01 to 1.5%, and a more preferable range is 0.01 to 1%. Among the impurities, the amounts of P and S that are mixed in with today's steel manufacturing technology (0.01 to 0.05%) do not affect the vibration damping ability of the steel of the present invention.
Ｃｕ，Ｎｉは原料にスクラップを使用する限り不可避で
あり、これらはオーステナイト形成元素であるが、０．
５％未満ならば本発明鋼の振動減衰能に影響を与えない
。Cu and Ni are unavoidable as long as scrap is used as a raw material, and these are austenite forming elements, but 0.
If it is less than 5%, it will not affect the vibration damping ability of the steel of the present invention.
なお、切削性向上のため、その効果が公知のＳ，Ｐｂの
少量の添加、または耐食性をさらに向上させるため、そ
の添加効果が公知のＭＯ，Ｎｉ，Ｃｕ等の少量の添加は
、本発明の効果を損うものではない。In addition, in order to improve machinability, addition of a small amount of S, Pb, etc., whose effect is known, or to further improve corrosion resistance, addition of a small amount of MO, Ni, Cu, etc., whose addition effect is known, is in accordance with the present invention. It does not impair the effect.
以上の成分範囲を有する本発明の防振鋼は最終冷延率と
最終焼鈍処理によつても振動減衰能は影響を受ける。The vibration damping ability of the vibration damping steel of the present invention having the above component range is also affected by the final cold rolling rate and final annealing treatment.
すなわち冷間加工により、ある程度内部歪を持たせ、そ

鈍処理は再結晶度以上であればよいが、７５０〜９５０
℃の温度範囲ての処理が適当であることがわかつた。な
お、最終冷延前の材料は熱延のままでもよいが、表面を
美麗に仕上げるため、或いは板厚調整のために、通常行
なわれている冷延率を３０〜９０％とする冷間圧延とそ
れに続く再結晶軟化焼鈍を１回以上施しておいた方が良
い。In other words, it is necessary to create a certain amount of internal strain through cold working, and then remove this internal strain as much as possible through annealing. Above is fine, but 750-950
It was found that treatment over a temperature range of ℃ is appropriate. Note that the material before the final cold rolling may be left as hot-rolled, but in order to finish the surface beautifully or to adjust the plate thickness, cold rolling with a cold rolling rate of 30 to 90%, which is usually performed, is recommended. It is better to perform the subsequent recrystallization softening annealing one or more times.
