本発明は、帯状クラツド材の製造方法に係り、
詳しくは帯状クラツド材の接合強度を高めること
のできる製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a band-shaped cladding material,
Specifically, the present invention relates to a manufacturing method that can increase the bonding strength of band-shaped cladding materials.
従来、帯状クラツド材を作るには、一般に接合
材料を不活性又は還元性ガス雰囲気中で加熱して
圧延ロールで加圧し、接合する方法が広く用いら
れている。 Conventionally, in order to make band-shaped cladding materials, a method has generally been widely used in which joining materials are heated in an inert or reducing gas atmosphere and then pressed with a rolling roll to join them.
しかし、この方法では全ての母材を接合できる
ものではなく、Beなどの非常に酸化し易く還元
しにくい成分を含有した合金の材料の接合は困難
であつた。 However, this method cannot join all base materials, and it has been difficult to join alloy materials containing components such as Be that are highly oxidizable and difficult to reduce.
即ち、接合材料の接合面の表面酸化の為、接合
強度が不十分で剥がれ等が生じ易いものである。
また高い接合強度を得る為に、加熱温度を上げた
り、圧延時の圧力をあげると、融点の低い材料等
では不均一な伸びや切断を受けたり或いは圧延ロ
ールが変形したりするものであつた。従つて、前
記接合材料のクラツド化は困難であつた。 That is, due to surface oxidation of the bonding surfaces of the bonding materials, the bonding strength is insufficient and peeling is likely to occur.
In addition, when raising the heating temperature or the pressure during rolling in order to obtain high joint strength, materials with low melting points may be subject to uneven elongation or cutting, or the rolling rolls may become deformed. . Therefore, it has been difficult to clad the bonding material.
本発明は斯かる問題を解消すべくなされたもの
であり、フラツクスを用いて接合材料を加熱、圧
延することにより、接合強度の高い帯状クラツド
材を得ることのできる製造方法を提供せんとする
ものである。 The present invention has been made to solve this problem, and aims to provide a manufacturing method that can obtain a band-shaped cladding material with high bonding strength by heating and rolling the bonding material using flux. It is.
本発明の帯状クラツド材の製造方法は、複数の
接合材料の少なくとも一方のBeを含有したCu合

用フラツクスを均一に塗り、然る後各接合材料を
不活性又は還元性ガス雰囲気中で加熱して接合面
を活性化し、各接合材の融点以下の温度で重合圧
延して塑性変形し圧着接合することを特徴とする
ものである。 The manufacturing method of the band-shaped clad material of the present invention is to uniformly apply Ag brazing flux to the entire surface or necessary parts of the joint surface of at least one of the plurality of joint materials, which is a Be-containing Cu alloy material, and then to each joint. The material is heated in an inert or reducing gas atmosphere to activate the bonding surfaces, and then polymerized and rolled at a temperature below the melting point of each bonding material to undergo plastic deformation and pressure bonding.
本発明の帯状クラツド材の製造方法に於いて、
Beを含有したCu合金の接合材料を不活性又は還
元性ガス雰囲気中で加熱する前に接合材料の接合
面にフラツクスを塗布する理由は、加熱時に生じ
る材料の酸化を防ぎ、また接合面に生じていた酸
化物を除去して接合面を活性化し、安定した高い
接合強度を得る為である。 In the method for manufacturing a band-shaped cladding material of the present invention,
The reason why flux is applied to the bonding surfaces of Cu alloys containing Be before heating them in an inert or reducing gas atmosphere is to prevent the oxidation of the materials that occurs during heating, and to This is to remove the oxides that were present and activate the bonding surface, thereby achieving stable and high bonding strength.
接合材料の接合面に塗布したフラツクスは、接
合材料の重合圧延の際絞られて接合面には残ら
ず、一部接合面以外に残つたフラツクスは湯洗等
により容易に除去できるので、帯状クラツド材の
製造上何ら支障が無い。 The flux applied to the joint surfaces of the joining materials is squeezed out during polymerization and rolling of the joining materials, and does not remain on the joint surfaces.Flux that remains on some surfaces other than the joint surfaces can be easily removed by washing with hot water, etc. There is no problem in manufacturing the material.
上記フラツクスとしては、Agろう用フラツク
ス（例えば硼酸30％、硼酸カリウム20％、弗化カ
リウム30％、硼弗化カリウム20％）を用いる。 As the above flux, a flux for Ag brazing (for example, 30% boric acid, 20% potassium borate, 30% potassium fluoride, 20% potassium borofluoride) is used.
