Description

아크용사에 의한 강판의 표면 연속 코팅 방법{The continued coating method of steel surface by Thermal spray}The continuous coating method of steel surface by Thermal spray}

본 발명은 판재의 강의 내부보호 및 식별등 도장의 효과를 얻기 위하여 강재표면에 용사코팅을 하는 표면처리의 방법에 대한 것이다.The present invention relates to a method of surface treatment of thermal spray coating on the surface of steel in order to obtain the effect of painting, such as internal protection and identification of steel of the plate.

지금 까지는 강재를 구입시 압연 공장에서 아연 코팅이나, 도장이 된 컬러코팅의 강재를 구입하였다, 그러나 이러한 방법들은 대량으로 구입하여야 하며, 소량 다품종을 요구하는 수요자의 요구에 부합하려면 대량의 구입품 중 일부를 사용하고 이를 보관함으로서 보관장소 및 보관에 의한 비용, 발청, 등 많은 문제를 발생하였다. 그리고 또 제작전, 후에 일반도장에 의한 방법이 있어나, 이것은 공해문제를 발생시킬 뿐 아니라 법적인 환경 규제로 설비의 신규 또는 증설이 어려운 실정이다. 따라서 수요자의 요구에 부합하고 소량으로도 처리가 가능하면서, 공해의 유발이 최소화 되는 새로운 방법이 요구되고 있었다.Until now, when purchasing steel materials, zinc-coated or painted color-coated steels were purchased from rolling mills, but these methods must be purchased in large quantities, and in order to meet the demands of consumers who require small quantities of various varieties, By using and storing it, there are many problems such as storage location and storage costs, claims, etc. In addition, there is a method by the general coating before and after the production, but this does not only cause pollution problems, it is difficult to add or expand the equipment due to legal environmental regulations. Therefore, a new method is required to meet the demand of the consumer and to be processed in small amounts, while minimizing the occurrence of pollution.

따라서 본 발명은 상기의 문제점을 해결하기 위하여 코일의 경우는 페이오프 릴과 텐션릴으로 모재을 이송시키고 이중 후판코일의 경우 레벨러를 통과 하여 평면화 하며, 판재의 경우는 롤러 콘베어에 의하여 모재를 이송하게 된다. 이 이송된 모재를 녹 제거를 위한 녹제거 브러쉬 장치 혹은, 쇼트의 장치에 의하여 표면의 녹을 제거하고 다음으로 아크 용사 장치에 의하여 상온의 평판 모재에 금속 도금을 하는 것을 골자로 하며, 이때 발생된 분진은 배출장치를 통하여 방지설비인 백 필터로 이송처리하며, 용사가 완료된 것은 텐션릴 혹은 보관장소에 보관 시키는 것이 주 내용이며, 보다 더 핵심내용은 상온으로 이송중인 광폭의 평판 모재에 아크 용사에 의하여 박막의 코팅을 함으로서 환경 친화적인 연속 코팅 방법을 제공함을 목적으로 한다.Therefore, in order to solve the above problems, the present invention transfers the base material to the payoff reel and the tension reel in the case of the coil, and flattens through the leveler in the case of the double plate coil, and transfers the base material by the roller conveyor in the case of the plate. . The transferred base metal is used to remove rust on the surface by a rust removal brush device or a short device for rust removal, and then metal plating the plate base material at room temperature by an arc spraying device. Silver is transported to the bag filter, which is a prevention device, through the discharge device, and the spraying is completed in the tension reel or storage place, and the main contents are more important by arc spraying on the wide plate base material being transported to room temperature. It is an object of the present invention to provide an environmentally friendly continuous coating method by coating a thin film.

상기의 목적을 달성하기 위한 본 발명은, 광폭 또는 협폭의 장대형 모재를 상온에서 아크 용사 방법으로 코팅할 수 있는 방법에 대한 것으로 첨부된 도면을 기준으로 설명하기로 한다.The present invention for achieving the above object, a method for coating a wide or narrow large-scale base material in the arc spray method at room temperature will be described with reference to the accompanying drawings.

도1은 본 발명에 의한 제청 브러쉬롤 부착 박판용 코팅 처리 주요장치도이며 도2는 본 발명에 의한 쇼트장치 부착 박판용 표면 처리 주요 장치도이고 도3은 아크용사 장치도의 일예를 도시한 것이다.Fig. 1 is a main apparatus diagram for coating thin plate with brushing roll roll according to the present invention, Fig. 2 is a main apparatus diagram for surface treatment for thin plate with short device according to the present invention, and Fig. 3 shows an example of an arc spray apparatus diagram.

이의 구성 및 작동을 설명하면. 중 박판의 코일 모재는 페이오프 릴(1)에 장착한 다음 이를 평판으로 하기위한 레벨러(2)를 통과 시키고 다음으로 녹제거장치인 브라쉬 장치(3) 또는 쇼트 장치(4)를 통과한다.If you explain its configuration and operation. Coil base material of the middle plate is mounted on the payoff reel (1) and then passed through the leveler (2) to make it into a flat plate, and then pass through the brush device (3) or the short device (4), which is a rust removal device.

발생된 녹을 제거한 상태의 평판을 아크열에 의하여 용해된 코팅재를 고압의 에어 분사 장치(5-2)에 의하여 고열의 상태로 모재에 부착시킬 수 있는 아크 용사 건 (5-1)이 내장된 용사장치(5)에서 코팅을 시키고 이것을 텐션릴(6)에 의하여 다시 코팅이 된 코일 강판으로 보관 후 제작의 소재로 이용된다. 여기에서 브라쉬 장치나, 쇼트장치에서 발생하는 분진과 다음 공정의 아크코팅 장치에서 발생하는 분진들을 각각의 혼합 에어 배출 장치(3-2)(5-3)인 에어 닥트를 통하여 집합시키고 이를 공해 방지 시설인 백 필트로 보내져서 분진을 제거하게 된다. 그리고 박판의 경우는 레벨러(2)를 생략 할 수도 있다. 이상은 코일 소재를 투입할 경우이며 판재의 소재를 투입경우는 레벨러와 텐션릴 대신에 이동용 로라 콘베어를 적용하여 판재를 이송시키며, 이송되는 판재의 녹제거 및 코팅의 기본 원리는 동일한 발명 기술이 적용됨으로 상세 설명은 생략하기로 한다. 본 발명의 기본요지는 이동하는 광폭 장대형의 판재를 녹 제거(3),(4)를 거치고 코팅 장치(5)에 의하여 상온에서 연속 코팅을 할 수 있는 방법을 제공한다.Thermal spraying device with built-in arc spray gun (5-1) that can attach the coating material dissolved by arc heat to the base material in the state of high heat by high pressure air injection device (5-2). The coating is carried out in (5) and stored as a coiled steel sheet coated again by the tension reel (6), and then used as a material for fabrication. Here, the dust generated by the brush apparatus or the short apparatus and the dust generated by the arc coating apparatus of the next process are collected through the air ducts, which are the respective air discharge apparatuses 3-2 and 5-3, and are polluted. It is sent to backfill, a prevention facility, to remove dust. In the case of a thin plate, the leveler 2 may be omitted. The above is the case of inputting the coil material, and in the case of inputting the material of the plate, the moving roller conveyor is applied instead of the leveler and the tension reel to transfer the plate, and the basic principle of rust removal and coating of the transferred plate is applied to the same invention technology. Detailed description will be omitted. The basic idea of the present invention is to provide a method for continuous coating at room temperature by the rust removal (3), (4) and the coating device (5) to move the moving plate of wide width.

이상으로 설명한 바와 같이 본 발명에 따르면 대형의 공장에서 대량으로 생산되어 공급하여 중소 공장에서는 비용의 부담과 치수의 선택의 범위가 한정되어 있는 것으로부터 필요한 소재를 소비자의 요구에 부합할 수 있는 소량으로 표면 처리를 하여 제작품의 생산을 할 수 있으며, 상온에서 코팅을 함으로서 일반 열에 의한 용사와 같은 열 변형의 배제가 가능하다. 공해가 없는 금속 코팅재를 아크열로 용해하여 분사하여 코팅을 행하는 방법으로 이는 소규모의 설비로도 코팅이 가능하여 경쟁력과 친 환경적인 코팅방법으로도 많은 효과가 있다.As described above, according to the present invention, a large amount is produced and supplied in a large factory, and in a small and medium-sized factory, a limited amount of cost and size selection are limited. The surface treatment can be used to produce products, and by coating at room temperature, it is possible to eliminate thermal deformation such as thermal spraying. It is a method of coating by spraying by dissolving metal coating material without pollution by arc heat, which can be coated by small-scale equipment, and thus has many effects as a competitive and environmentally friendly coating method.
