Of course, the present invention relates to an electro-induction heating container coating method that can increase wear resistance, corrosion resistance, heat resistance, and the like.

일반적으로 전자유도가열 방식으로 사용되어지는 용기의 바닥부 및 측면 등의 전체 부분에는 용기를 가열시키게 되는 자성체 금속판이 일체형으로 성형되어 있다.In general, a magnetic metal plate for heating the container is integrally formed on the entire part of the bottom, side, and the like of the container used by the electromagnetic induction heating method.

종래에 사용되고 있는 전자유도가열 용기는 용기 본체에 자성체 금속판이 부착되어지고 자성체 금속판 외면에 코팅재로 자성체 금속판이 떨어지지 않도록 마감하게 된다.Electromagnetically induction heating container used in the prior art is a magnetic metal plate is attached to the container body and the magnetic metal plate to the outer surface of the magnetic metal plate to the finish so that the magnetic metal plate does not fall.

그러나 종래의 자성체 금속판은 부착성이 양호하지 못하여 사용중 용기 본체 바닥부로부터 박리되는 현상이 발생하게 될 뿐 아니라 발열에 의해 휘어지게 되므로 열효율이 떨어지게 되는 문제가 있다.However, the conventional magnetic metal plate has a problem that the adhesive efficiency is not good, not only does not peel off from the bottom of the container body during use, but also bends due to heat generation, thereby deteriorating thermal efficiency.

따라서, 본 발명은 상기한 문제를 해결하기 위하여 안출한 것으로 용기 본체에 프라즈마용사코팅 또는 면상발열체를 이용한 코팅방식으로 철 성분의 자성체를 코팅 성형하므로 자성체의 부식을 방지할 수 있으며, 작업의 편리성 및 제품의 견고성을 향상시킬 수 있도록 한 전자유도가열 용기 코팅방법을 제공하고자 하는 데 그 목적이 있다.Therefore, the present invention has been made in order to solve the above-mentioned problems, so as to coat the magnetic material of the iron component in a coating method using a plasma spray coating or a planar heating element to the container body can prevent corrosion of the magnetic body, convenience of work And to provide an electron induction heating container coating method that can improve the robustness of the product.

상기한 목적을 달성하기 위한 본 발명은 전자유도가열 용기에 철 성분의 자성체를 건(gun)에 주입하여 용기 본체에 분사하게 되는 아크용사나 플라즈마용사 등의 용사코팅 방법으로 피막시키게 됨을 특징으로 하는 전자유도가열 용기 코팅방법을 제공함에 있는 것이다.The present invention for achieving the above object is characterized in that the magnetic injecting a magnetic substance of the iron component in the electron induction heating container to the coating by a thermal spray coating method such as arc spraying or plasma spraying to be sprayed on the container body It is to provide an electron induction heating container coating method.

이하, 첨부된 도면을 참조하여 본 발명에 따른 일실시 예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 용기의 일 예를 도시한 절단면도이며, 도 2는 본 발명에 따른 용기에 자성체를 코팅하게 되는 사용상태도로서,1 is a cross-sectional view showing an example of a container according to the present invention, Figure 2 is a state diagram used to coat the magnetic material on the container according to the present invention,

본 발명은 전자유도가열 용기(1)에 용기(1)를 가열시킬 수 있도록 철 성분의 자성체(2)를 성형함에 있어서,In the present invention, in forming the magnetic body (2) of the iron component to heat the container (1) in the electromagnetic induction heating container (1),

상기 철 성분의 자성체(2)를 분무기(gun)(3)에 주입시켜 자성체(2)의 용사 재료를 가열하여 용융시킴과 동시에 분무기(3)의 노즐(3a)을 통해 외부로 분사시켜 용기(1)에 피막시키게 되는 용사코팅법으로 코팅 제조하는 것이다.The iron magnetic body 2 of the iron component is injected into a gun 3 to heat and melt the thermal spraying material of the magnetic body 2, and at the same time, it is sprayed to the outside through the nozzle 3a of the sprayer 3. It is to prepare a coating by thermal spray coating method to be coated in 1).

상기에서 용사코팅법은 아크용사(Ary Spraying)나 대기 플라즈마용사(Atmospheric Plasma Spraying) 등의 플라즈마용사코팅방법을 사용하거나 또는 면상발열체(4)를 이용한 코팅법이 적용되어지게 되는 것이다.The thermal spray coating method is to use a plasma spray coating method such as Ary Spraying or Atmospheric Plasma Spraying, or a coating method using the planar heating element 4 is to be applied.

상기의 아크용사는 두 개의 선재를 전극으로 하고, 전극 끝 부분에 아크를 발생시켜 용사 재료인 자성체를 용융시킴과 동시에 압축공기 제트로 분사ㆍ비행시켜 철 성분의 자성체를 용기에 피막시키게 되는 것이다.The above arc spraying uses two wires as electrodes, and arcs are generated at the electrode ends to melt the magnetic material, which is the thermal spraying material, and to spray and fly with a compressed air jet to coat the iron magnetic material in the container.

또한 아크용사는 아크로 용사 재료인 자성체를 용융시키기 때문에 고능률 용사가 가능하고, 다형소재의 피막형성, 소모소재의 오버레이 용사에 사용이 용이하게 된다.In addition, arc spraying enables high efficiency spraying because it melts a magnetic material, an arc spraying material, and is easy to use for forming a film of a polymorphic material and overlaying spraying of a consumed material.

상기 대기 플라즈마용사는 Ar, He, N2 등의 가스를 아크로 플라즈마화하고, 이것을 노즐로부터 배출시켜 초고온, 고속의 플라즈마 제트를 열원으로 하는 피막형성이다.The atmospheric plasma spray is a film formation in which gases such as Ar, He, N2, etc. are converted into arcs by plasma, and discharged from the nozzles to form a heat source using a very high temperature and high velocity plasma jet.

이때, 상기 플라즈마 발생장치는 Cu로 된 원형의 양극과 W로 된 음극으로 구성되며, 발생장치에서 전기 아크 방전이 작동가스를 플라즈마화하여 제트를 형성하게 되는 것이다.At this time, the plasma generator is composed of a circular anode of Cu and a cathode of W, the electric arc discharge in the generator is to form a jet to the plasma working gas.

상기에서 대기 플라즈마용사의 장점을 간략히 설명하면, 고융점의 W,Mo같은 금속과 세라믹 코팅에 필수적이며 유일한 용사기법이며, 금속 및 세라믹스 등 안정한 용융현상을 수반하는 물질이라면 용사가 가능하기 때문에 피막재료의 선택 영역이 높고, 플라즈마 제트(Plasma jet)의 속도가 크므로 자성체인 용사 재료가 고속으로 피처리물인 용기에 충돌하고 이로 인해 고밀착 강도, 고밀도의 피막 제조가 가능하게 된다.Briefly, the advantages of atmospheric plasma spraying are essential for the coating of metals and ceramics, such as high melting point W and Mo, and are the only spraying technique. Since the selection area of the film is high and the velocity of the plasma jet is high, the thermal spraying material, which is a magnetic material, collides with the container to be processed at a high speed, thereby making it possible to manufacture a film with high adhesion strength and high density.

또한, 대기 플라즈마용사는 대출력화가 용이하므로 단위시간당 용사량이 커서 작업성이 좋고 경제성이 높은 공법이며, 무산소, 무탄소이며 청정, 열화학적 활성인 열원이기 때문에 용사 재료의 오염 및 변화가 적으며, 열원의 종류와 조건에 의해 용사비행 입자의 온도, dwell time, 분위기 가스성분과의 접촉시간 특히 모재표면에의 충돌에너지, 급냉응고속도 등이 달라지며, 즉 용사피막의 물리화학적 성질이 크게 달라지게 되는 것이다.In addition, the atmospheric plasma spraying is easy to increase the output, the large amount of spraying per unit time, workability is good and economical high efficiency method, oxygen-free, carbon-free, clean, thermochemically active heat source, less pollution and change of thermal spraying material, Depending on the type and condition of the heat source, the temperature of the thermal spray particles, the dwell time, the contact time with the atmospheric gas components, in particular, the collision energy to the surface of the base material, the quenching and solidification speed, etc. Will be.

상기 면상발열체를 이용한 코팅의 면상발열체(4)는 얇은 필름상, 또는 면상 자체가 발열함으로서 주변으로 열손실이 거의 없으며, 처음 설정된 온도 이상 올라 가지 않고 디지털 온도 조절기로 정확한 온도를 조절해 면 전체에 일정 온도로 발열할 수 있어 안정성이 향상된 히터이며, 또한 저항체 일부분 즉 검은 발열부분이 손상되어도 그 부분 이외의 발열에는 지장을 주지 않아 유지 보수가 용이하게 된다.The planar heating element 4 of the coating using the planar heating element has almost no heat loss to the surroundings due to the heat generation of the thin film or the plane itself, and does not rise above the first set temperature, and the digital temperature controller adjusts the correct temperature to the entire surface. It is a heater having improved stability because it can generate heat at a constant temperature, and even if a portion of the resistor, that is, the black heat-generating portion, does not interfere with heat generation other than that portion, thus making maintenance easy.

본 발명에 따른 용기의 또 다른 코팅방법을 살펴보면, 첨부된 도면 도 3에 도시된 바와 같이 유리 재질의 용기(1) 면에 상기와 같은 아크용사나 플라드마용사 등의 용사코팅법으로 철 성분의 자성체(2)를 코팅하여 피막시킨 다음 자성체(2)가 피막된 외면에 외부틀(1a)을 용기(1)와 일체로 성형하게 된다.Looking at another coating method of the container according to the present invention, as shown in Figure 3 of the accompanying drawings, the surface of the container (1) of the glass material of the iron component by the thermal spray coating method such as arc spraying or plasma spraying The magnetic body 2 is coated and coated, and then the outer frame 1a is integrally formed with the container 1 on the outer surface of the magnetic body 2 coated.

By coating 2) integrally with the container 1, a coating film having a high bonding strength can be obtained, and the magnetic body 2 is not separated from the container 1.

또한 상기 전자유도가열 용기(1)에 자성체(2)를 용사법으로 분사하여 한 번의 작업으로 피막시키게 됨으로 작업의 효율 및 생산성을 높일 수 있게 되는 것이다.In addition, the magnetic body 2 is sprayed onto the electromagnetic induction heating container 1 by spraying to coat the film in one operation, thereby increasing the efficiency and productivity of the work.

이와 함께 상기 전자유도가열 용기(1)에 가열성 자성체(2)를 견고하게 코팅시켜 높은 온도에도 자성체(2)가 박리되지 않게 됨으로 가열성을 높여 용기(1)내의 내용물을 단시간에 가열시키게 되는 것이다.In addition, by heating the magnetic magnetic material 2 to the electromagnetic induction heating container (1) firmly so that the magnetic material (2) does not peel even at a high temperature to increase the heating properties to heat the contents in the container (1) in a short time will be.
