이하, 본 발명의 바람직한 실시예에 대해서 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail.
본 발명의 바람직한 실시예에서는 성형 가공용 합금판재의 크레드 제조방법으로서, 동판이나 황동판 같은 모재를 표면 처리하고, 크레드재로서 알루미늄을 브러싱이나 샌딩 처리한 다음에, 이들 부재를 열간 압연하여 견고하게 압착시키는 방안을 예시하였다. 본 발명에 따라 제조되는 합금판재는 2중으로 하거나 알루미늄을 교대로 개재시켜 3중 또는 그 이상의 다중층 구조로 하는 것도 가능하다.In a preferred embodiment of the present invention, as a method for producing a cradle of an alloy plate material for forming, surface treatment of a base material such as a copper plate or a brass plate, and brushing or sanding aluminum as a crad material, followed by hot rolling of these members to be firmly pressed. The scheme is illustrated. The alloy sheet produced in accordance with the present invention may be doubled or alternately interposed aluminum to have a triple or more multilayer structure.
이러한 열간 압연공정에 의한 합금판재의 크레드 제조방법은 전체적으로, 동판, 황동판, 철판으로 이루어진 그룹으로부터 선택된 모재의 표면을 니켈 또는 크롬 산화방지 처리하는 단계(a)와, 알루미늄 표면을 브러싱 또는 샌딩 처리하는 단계(b)와, 상기 모재에 브러싱 또는 샌딩 처리된 알루미늄을 맞붙인 상태에서 300∼400℃의 온도로 가열하는 단계(c)와, 상기 모재와 알루미늄을 30∼40㎏/㎠의 압력으로 압연하여 압착시키는 단계(d)와, 상기 압착후에 300∼400℃의 온도로 재가열하는 단계(e)를 거쳐 만들어진다.The method of manufacturing a cradle of an alloy plate material by such a hot rolling process includes the steps of (a) treating the surface of a base material selected from the group consisting of a copper plate, a brass plate, and an iron plate with nickel or chromium oxidation, and brushing or sanding the aluminum surface. Step (b), the step (c) of heating to a temperature of 300 ~ 400 ℃ in the state in which the brushed or sanded aluminum bonded to the base material, and rolling the base material and aluminum at a pressure of 30 ~ 40kg / ㎠ By pressing step (d) and after the pressing step (e) of reheating to a temperature of 300 ~ 400 ℃.
여기에서, 모재로는 다양한 재질을 이용할 수 있으나, 내부식성 및 성형성이 우수한 동판을 비롯하여 황동판이나 철이 많이 함유되어 있는 철판을 사용하였다. 또한, 이들 모재의 표면은 니켈이나 크롬을 도금하여 산화를 방지한다. 이와 같이,산화 처리를 마친 모재의 표면은 열을 가하거나 물이나 기타 이물질과 접촉되어도 산화되지 않게 되어 내부식성이 향상된다.Here, a variety of materials may be used as the base material, but a brass plate or an iron plate containing a lot of iron is used, including a copper plate having excellent corrosion resistance and formability. In addition, the surface of these base materials is plated with nickel or chromium to prevent oxidation. As such, the surface of the base material which has been oxidized is not oxidized even when heated or in contact with water or other foreign substances, thereby improving corrosion resistance.
다음에, 크레드로서 사용하는 알루미늄의 경우에는 모재와의 접착력을 증대시키기 위한 방안으로 브러시를 이용하여 표면을 브러싱 처리하거나 샌드 페이퍼를 이용하여 샌딩 처리한다. 표면 처리된 알루미늄을 니켈 또는 크롬 도금된 모재와 밀착시킨 상태에서 300∼400℃의 온도로 가열시킨다.Next, in the case of aluminum to be used as a crad, the surface is brushed using a brush or sanded using sand paper in order to increase the adhesive force with the base material. The surface-treated aluminum is heated to a temperature of 300 to 400 ° C. in close contact with the nickel or chromium plated base material.
300∼400℃의 온도에서 소정시간 가열하여 어느 정도 용융된 상태에서, 적절한 가압롤러를 이용하여 용융된 2개의 금속을압연하여 부착시킨다. 이때, 소재의 이송속도는 모재에 크레드가 압착되기에 충분한 속도로 이송시키면 된다.After heating for a predetermined time at a temperature of 300 to 400 ° C. and in a molten state to some extent, two molten metals are rolled and attached using an appropriate pressure roller. At this time, the feed rate of the material may be transferred at a speed sufficient to press the crad to the base material.
모재에 알루미늄 크레드가 압착되고 나면, 다시 300∼400℃의 온도로 재가열하여 2금속 간의 결합력이 보다 증대되도록 한다. 소정시간 동안 가열한 후에, 접착된 소재는 적절한 속도(가령, 100℃/min 이상)로 자연냉각함으로써 충분한 강도및 경도를 유지할 수 있도록 한다.After the aluminum clad is pressed to the base material, it is reheated again at a temperature of 300 to 400 ° C. to increase the bonding strength between the two metals. After heating for a predetermined time, the bonded material is allowed to naturally cool at an appropriate rate (eg, 100 ° C./min or more) to maintain sufficient strength and hardness.

First, nickel plating on the copper plate was performed to prevent oxidation, and then the aluminum surface was brushed using a brush to clean the contact surface. Next, after heating to a temperature of about 350 ° C. while brushed aluminum is brought into contact with the nickel plated copper plate, the metals are rolled at a pressure of about 35 kg / cm 2 using a conventional pressure roller to be firmly attached.

First, the brass plate was oxidized by chrome plating, and then the aluminum surface was sanded using sand paper. To clean the contact surface. Then, after heating to a temperature of about 400 ℃ in contact with the sanded aluminum chrome plated brass plate, using a conventional pressure roller to roll these metals at a pressure of about 40kg / ㎠ to firmly adhere It was. Next, the compressed material was reheated to a temperature of about 380 ° C. The brass plate-aluminum alloy plate material thus prepared was also confirmed through experiments of excellent thermal conductivity, corrosion resistance and strength.
이밖에도, 본 발명에 따른 합금판재의 크레드 제조방법에 의해서, 상술한 동판-알루미늄이나 황동판-알루미늄 이외에도철판-알루미늄과 같은 2중 구조가 가능하며, 경우에 따라서는 동판-알루미늄-황동판-알루미늄-스텐판과 같은 5중구조나 동판-알루미늄-황동판-알루미늄-철판-알루미늄-스텐판과 같은 7중 구조와 같이 3∼7중 구조를 갖는 다중층 구조로도 제조할 수 있다.In addition, by the method of manufacturing a cradle of an alloy sheet according to the present invention, in addition to the above-described copper plate-aluminum or brass plate-aluminum, a double structure such as iron plate-aluminum is possible, and in some cases, copper plate-aluminum-brass plate-aluminum-sten It can also be produced in a multi-layer structure having three to seven structures, such as a five-layer structure such as a plate or a seven-layer structure such as copper plate-aluminum-brass plate-aluminum-iron plate-aluminum-sten plate.
이상으로 설명한 본 발명에 의하면, 동판, 황동판, 철판을 모재로 하고 알루미늄 스텐판을 크레드재로 하여 제조하게 되며, 그 제조방법을 보면, 먼저, 동판, 황동판, 철판 표면을 니켈 또는 크롬 산화방지 처리하고, 알루미늄 표면을 브러싱또는 샌딩처리하고, 다음에, 300∼400℃의 온도로 가열하고 30∼40의 압력으로 압연한 후에, 300∼400℃의 온도로 재가열하여 만들기 때문에, 열전도율이 높고 내부식성이 향상되어 수명이 연장되는 이점이 있다.According to the present invention described above, the copper plate, the brass plate, the iron plate as a base material, and the aluminum stainless plate as a crad material to manufacture, looking at the manufacturing method, first, the surface of the copper plate, brass plate, iron plate nickel or chromium oxidation treatment The surface of the aluminum is brushed or sanded, and then heated to a temperature of 300 to 400 ° C., rolled to a pressure of 30 to 40, and then reheated to a temperature of 300 to 400 ° C., thereby providing high thermal conductivity and corrosion resistance. This has the advantage that the life is extended.
