本発明は銅または銅合金材の焼鈍方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for annealing copper or copper alloy materials.
巻線などの製造において、銅または銅合金材を
冷間圧延後ボビン巻きして焼鈍することが行なわ
れるが、銅または銅合金材が焼鈍によりくつつく
という問題がある。 BACKGROUND ART In the production of winding wires and the like, copper or copper alloy materials are cold-rolled, wound on bobbins, and annealed, but there is a problem that the copper or copper alloy materials become loose during annealing.
従来、このような銅または銅合金材のくつつき
防止法としては、(1)銅または銅合金圧延材のボビ
ン巻取張力を小さくする方法、(2)焼鈍温度を下げ

銅合金圧延材を巻き取る際、圧延材表面にシリコ
ーンオイルの塗布や、圧延材間に介在物を入れて
巻き取る方法などがある。 Conventionally, methods for preventing such sticking of copper or copper alloy materials include (1) a method of reducing the bobbin winding tension of rolled copper or copper alloy materials, (2) a method of lowering the annealing temperature, and (3) a method of reducing the annealing temperature. (4) When winding a rolled copper or copper alloy material, there are methods such as applying silicone oil to the surface of the rolled material or inserting inclusions between the rolled materials before winding it up.
上記(1)については、巻取張力を小さくすると、
圧延材がゆる巻きになり、すり傷が発生する。
(2)、(3)については、圧延材において希望する特性
値が得られない。(4)については、焼鈍時に圧延材
表面に塗布されたシリコーンオイルが流出して、
焼鈍炉内を汚したりする。 Regarding (1) above, if the winding tension is reduced,
The rolled material becomes loosely rolled and scratches occur.
Regarding (2) and (3), the desired characteristic values cannot be obtained in the rolled material. Regarding (4), the silicone oil applied to the surface of the rolled material during annealing leaks out.
Doing so may stain the inside of the annealing furnace.
また、介在物を入れて巻き取る方法は、介在物
を送り出す装置と介在物を回収する装置が必要で
あり、工程が増えて不経済であるという問題があ
る。 Further, the method of winding the film with inclusions requires a device for sending out the inclusions and a device for collecting the inclusions, which increases the number of steps and is uneconomical.
本発明の目的は、前記した従来技術の欠点を解
消し、銅または銅合金材の表面性状を圧延ロール
により調整することによりくつつきを防止し、も
つてくつつき傷のない健全な焼鈍材を効率的に得

供することにある。すなわち、本発明の要旨は、
銅または銅合金材をロール表面を80〜800番の範
囲で適度に粗くした圧延ロールを用いて冷間圧延
し、これによりロール表面の粗度が転写された銅
または銅合金材をボビン巻きして焼鈍することに
ある。 The purpose of the present invention is to eliminate the drawbacks of the prior art described above, to prevent scratches by adjusting the surface properties of copper or copper alloy materials using rolling rolls, and to efficiently produce sound annealed materials without scratches. It is an object of the present invention to provide a method for annealing copper or copper alloy materials that can be obtained in a manner that allows for the annealing of copper or copper alloy materials. That is, the gist of the present invention is
Copper or copper alloy material is cold rolled using a rolling roll whose surface is moderately roughened in the range of No. 80 to 800, and the copper or copper alloy material with the roughness of the roll surface transferred is then wound on a bobbin. It is then annealed.
次に、本発明方法を一実施例により説明する
と、電気用平角銅線の製造において、前記銅線を
ロール表面を80〜800番の範囲で適度に粗くした
圧延ロールを用いて所望形状に圧延し、圧延材を
ボビン巻きした後、これを光輝焼鈍した。 Next, to explain the method of the present invention with an example, in the production of rectangular copper wire for electrical use, the copper wire is rolled into a desired shape using a rolling roll whose roll surface is appropriately roughened in the range of No. 80 to 800. After winding the rolled material into a bobbin, it was brightly annealed.
焼鈍後、炉から取り出してみたが、平角銅線同
志のくつつきは見られなかつた。 When I took it out of the furnace after annealing, I could not see any pecking of the flat copper wires.
ちなみに、ロール表面が1000番の粗さの圧延ロ
ールを用いて銅線を圧延した場合、光輝焼鈍後く
つつきが見られた。 Incidentally, when copper wire was rolled using a rolling roll with a roll surface roughness of No. 1000, pecks were observed after bright annealing.
また、ロール表面が80番以下の粗さの粗い圧延
ロールを用いて銅線を圧延した場合、光輝焼鈍後
くつつきは見られないが、平角銅線としての品質
上問題となる。 In addition, when a copper wire is rolled using a rolling roll with a roughness of No. 80 or less on the roll surface, no pecks are observed after bright annealing, but this poses a quality problem as a rectangular copper wire.
このように、本発明は銅または銅合金材をロー
ル表面を80〜800番の範囲で適度に粗くした圧延
ロールを用いて冷間圧延するから、銅または銅合
金材表面にはロール表面の粗度が転写されて微小
凹凸ができ、この凹凸によつて圧延材同志の接触
面積が減少するために、圧延材をボビン巻きして
焼鈍してもくつつくことがなく、したがつてくつ
つき傷のない健全な焼鈍材を得ることができる。 As described above, since the present invention cold-rolls copper or copper alloy material using rolling rolls whose roll surface is moderately roughened in the range of No. 80 to 800, the surface of the copper or copper alloy material has a roughened roll surface. The roughness is transferred and minute irregularities are created, and these irregularities reduce the contact area between the rolled materials, so even when the rolled materials are wound on a bobbin and annealed, they do not flop, resulting in scratches. It is possible to obtain a sound annealed material without any
また、本発明は圧延ロールを用いてくつつきを
防止することから、製造工程を煩雑にしないの
で、きわめて経済的である効果がある。 Furthermore, since the present invention uses rolling rolls to prevent pecking, the manufacturing process is not complicated, so it is extremely economical.
なお、従来くつつき防止法の一つとして、焼鈍
工程中圧延材のボビン巻き替えを行なうことがあ
るが、本発明によればその必要はなく、きわめて
効率的に焼鈍を行なうことができる。 In addition, as one of the conventional methods for preventing sticking, the rolled material may be re-wound to the bobbin during the annealing process, but according to the present invention, this is not necessary and annealing can be performed extremely efficiently.
