Description
본 발명은 연강, 탄소강 등 저렴한 강판에 내식, 내산성 등이 우수한 고가의 닉켈기 합금판을 접합시킨 닉켈합금 클래드판의 제조 방법 및 이와 같은 방법에 의해 제조된 닉켈합금 클래드판에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a nickel alloy clad plate obtained by bonding an expensive nickel alloy plate having excellent corrosion resistance, acid resistance, etc. to an inexpensive steel sheet such as mild steel and carbon steel, and a nickel alloy clad plate produced by such a method.
클래드판은 탄소강판 등 저렴한 가격의 베이스메탈에 내식, 내산성 등이 우수한 고가의 금속판을 포개어 놓고 접합시킨 이종금속이 접합되어 있는 판으로서, 저렴하면서도 기계적 성질 등이 뛰어난 강판의 특성과, 내식, 내산성 등이 우수하지만 고가이어서 사용에 제한을 받는 특수금속의 특성을 동시에 효과적으로 이용할 수 있는 이점이 있는 것이어서 현재 정유, 담수설비, 발전소 탈황설비 분야 등의 내식성, 내산성 등을 요하는 곳에 많이 사용되고 있다.Clad plate is a plate in which dissimilar metals are bonded by laminating expensive metal plates, such as carbon steel sheets, and high-speed metal plates with excellent corrosion resistance and acid resistance, and are inexpensive and have excellent mechanical properties, corrosion resistance and acid resistance. It is excellent in price, but it is expensive, so it has the advantage of effectively utilizing the characteristics of special metals that are restricted in use.
특히, 발전소 보일러 분야에서는 연료로 주로 사용되고 있는 중유 또는 석탄 등이 연소시 심각한 공해문제를 야기시키는 다량의 아황산가스를 발생하기 때문에 이들 아황산가스를 포집제거시키기 위한 탈황설비를 설치하는 것이 의무화되어 있다. 그러나 이들 탈황설비의 흡수탑, 닥트, 굴뚝등은 아황산가스에 그대로 노출되는 부위이기 때문에 이들가스에 의해 쉽게 부식되어 설비의 수명이 단축되고 이들 설비를 수시로 교체해야 하는 번거러움이 있는 등 많은 문제가 있었다.In particular, in the power plant boiler field, since heavy oil or coal, which is mainly used as a fuel, generates a large amount of sulfurous acid gas which causes serious pollution problems during combustion, it is mandatory to install a desulfurization facility for capturing and removing these sulfurous acid gases. However, since absorption towers, ducts, and chimneys of these desulfurization facilities are exposed to sulfur dioxide, they are easily corroded by these gases, which shortens the service life of the facilities and hassles to replace these facilities from time to time. .
이들 문제를 해결하기 위한 방법으로 설비의 아황산가스에 노출되는 부위를 내식, 내산성이 우수한 금속을 통째로 사용하여 제작하는 방법과, 내식 내산성을 갖는 금속판을 저렴한 가격의 강판에 접합시킨 클래드판을 사용하여 제작하는 방법 등이 제안되고 있으나, 내식 내산성이 우수한 금속을 통째로 사용하여 설비를 제작하는 것은 그 금속이 고가이어서 제작비용이 엄청날 뿐만 아니라 부수되는 설치시공상의 문제점 등으로 사용에 제한이 따르기 때문에 최근에는 클래드판이 많이 사용되고 있는 실정이다.In order to solve these problems, a method of manufacturing a part exposed to sulfur dioxide gas in a facility using a metal having excellent corrosion resistance and acid resistance, and a clad plate obtained by joining a metal plate having corrosion resistance acid resistance to a steel plate of low price Although manufacturing methods have been proposed, manufacturing equipment using a whole metal having excellent corrosion resistance is not only expensive due to the high cost of the metal, but also due to limitations in installation and construction problems. Clad plate is used a lot.
종래의 클래드판을 제조하는 기술로는 화약의 폭발력을 이용해서 모재인 탄소강판에다 내부식성 금속판을 접합하는 폭발용접클래드 제조방법과, 열간압착 롤라에 의해 접합하는 롤본드 클래드 제조방법과, 스텐레스망, 구리망 또는 구리박판을 바인더로 사용하여 저항심용접하는 방법 등을 들 수 있는데, 상기 방법 중 폭발용접 클래드재와 롤본드재는 품질은 우수한 것으로 나타나고 있으나 제조경비가 과다하게 소요될 뿐 아니라 가공성 및 현장 시공성이 좋지 않고 재료의 낭비가 많아 실제 사용자들이 기피하는 경향이 있다. 반면에 스텐레스망, 구리망 또는 구리박판을 바인더로 사용하여 저항심용점을 한 클래드 재는 상기 폭발용접이나 롤본드 클래드재보다 경제성이 우수하여 현장에서 많이 사용되고 있다.Conventional clad plate manufacturing techniques include explosive welding cladding method for joining a corrosion-resistant metal plate to a base carbon steel plate using explosive force of gunpowder, roll bond cladding method for joining by hot pressing roller, stainless steel net And resistance welding using copper mesh or copper foil as a binder. Among the above methods, the explosion welding cladding material and the roll bonding material have been shown to be excellent in quality, but not only excessive manufacturing cost but also workability and field workability. This is not good and the waste of material tends to be avoided by real users. On the other hand, the cladding material made of stainless steel, copper mesh or copper foil as a binder has a resistance core point, and is more economically used than the explosion welding or roll bond cladding material.
그러나 상기 심저항 용접방식은 바인더로 사용되고 있는 스텐레스망, 구리망 또는 구리박판이 모재인 강판과 내식합금판을 효과적으로 접합시키지 못하여 인장강도, 박리강도, 전단강도 등 기계적성질이 열악하여 수요가의 기대를 충족시키지 못하는 문제가 있다.However, the core resistance welding method fails to effectively bond the steel plate and the corrosion resistant alloy plate of stainless steel, copper mesh or copper foil, which is used as a binder, and is poor in mechanical properties such as tensile strength, peeling strength, and shear strength, and thus the demand is expected. There is a problem that does not meet.
본 발명은 상기 문제를 해결하기 위하여 안출한 것으로 모재로 사용되는 강판과 내식성이 우수한 닉켈합금판을 강력하게 접합하므로서 인장강도 등 기계적 성질이 우수하면서 내식내산성이 우수한 닉켈기 합금 클래드판을 제조하는 방법을 제공하는 것을 그 목적으로 한다.The present invention has been made in order to solve the above problems, a method for producing a nickel-based alloy clad plate excellent in corrosion resistance and acid resistance while excellent mechanical properties such as tensile strength by strongly bonding the steel plate used as a base material and the nickel alloy plate excellent in corrosion resistance. To provide that purpose.
제 1 도는 본 발명에 의해 제조된 닉켈합금 클래드판의 확대사시도이다.1 is an enlarged perspective view of a nickel alloy clad plate produced by the present invention.

본 발명은 상기 목적을 달성하기 위하여 소정의 강도를 갖는 모재와, 내식, 내산성이 우수한 닉켈기 합금판 사이에 바인더로서 닉켈박판 또는 닉켈스트립 또는 스텐레스 박판 또는 스텐레스스트립을 끼워넣고 심저항용접하는 것을 특징으로 하는 닉켈합금 클래드판을 제조하는 방법을 제공하며, 또한 강판과 닉켈기 합금판 사이에 닉켈박판 또는 닉켈스트립 또는 스텐레스박판 또는 스텐레스 스트립이 합금화된 상태로 용접되어 있는 것을 특징으로 하는 강판편면에 닉켈기 합금판이 접합된 클래드강판을 제공한다.In order to achieve the above object, the present invention is characterized by inserting a nickel plate or nickel strip or stainless steel sheet or stainless strip as a binder between a base material having a predetermined strength and a nickel-based alloy plate having excellent corrosion resistance and acid resistance. Nickel alloy clad plate to provide a method, and Nickel thin plate or Nickel strip or stainless steel sheet or stainless strip between the steel plate and the nickel-based alloy plate is welded in the alloyed state nicked on one side of the steel sheet Provided is a clad steel sheet bonded with a Kelki alloy sheet.
이하에 본 발명을 상세히 설명한다.The present invention is described in detail below.
본 발명은 모재인 탄소강판에다 바인더(Binder) 역할을 하는 닉켈박판 또는 스텐레스박판 또는 닉켈스트립 또는 스텐레스 스트립을 가접한 다음 그 위에 내부식성이 우수한 닉켈합금판을 포개놓은 상태에서 저항심용접해서 닉켈합금클래드판을 제조하는 것을 그 특징으로 하고 있으며, 본 발명에서 강판과 닉켈합금판이 접합되는 것은 모재인 강판과 닉켈기 합금판 사이로 고전류가 통전되면 전기저항열에 의해 고열이 순간적으로 발생하고 이 고열에 의해 바인더가 녹으면서 강판 및 닉켈기합금판과 합금화되면서 강판과 합금판을 강력하게 접합하는 원리를 이용한 것이다.Nickel alloy clad by resistance welding in a state in which a nickel plate or stainless sheet or nickel strip or stainless strip serving as a binder is welded on a base carbon steel plate and then a nickel plate is excellent in corrosion resistance is superimposed thereon. In the present invention, the plate and the nickel alloy plate are bonded to each other. In the present invention, when a high current is supplied between the base steel plate and the nickel alloy plate, high heat is instantaneously generated by heat of electrical resistance and the binder is caused by the high heat. Is melted and alloyed with the steel sheet and nickel-based alloy plate while using the principle of strongly bonding the steel sheet and alloy plate.
이때 강판과 합금판의 용착을 원할히 하기 위하여 바인더상에 플럭스를 도포할 수도 있다.At this time, the flux may be applied onto the binder in order to facilitate welding of the steel sheet and the alloy plate.
모재를 탄소강판으로 사용하는 것은 탄소강판이 소정이상의 강도를 유지하고 가격이 저렴하여서 강도유지용으로 적합하기 때문이며;The use of the base material as the carbon steel sheet is because the carbon steel sheet maintains a predetermined strength or more and is inexpensive and is suitable for maintaining strength;
바인더로서 닉켈박판, 스텐레스박판, 닉켈스트립, 스텐레스 스트립을 선택한 것은 닉켈박판과 스텐레스박판이 모재인 탄소강판 및 닉켈합금판과 동일 내지 유사한 금속이어서 융착하는 과정에서 합금화가 용이하여 강력한 결합력을 갖을 수 있기 때문이며, 그 접착부위가 종래의 스텐레스망 또는 구리망보다 넓어서 강력한 결합력을 갖는 것이 가능하기 때문이다.Nickel thin plate, stainless thin plate, nick strip, and stainless strip as binders are the same or similar metals as carbon steel plate and nickel plate, which are the base metals. This is because the bonding portion is wider than the conventional stainless steel or copper mesh, and thus it is possible to have a strong bonding force.
더군다나 닉켈박판과 스텐레스박판 대신에 스트립을 사용하는 것은 심저항용접 되는 부위만 바인더로서 스트립을 사용하고 용접되지 않는 부위는 바인더가 필요없는 부위이므로 재료를 사용하지 않음으로서 재료를 절감하기 위함이고, 이에 따라 자체 중량도 현저하게 줄일 수 있는 이점이 있기 때문이다.In addition, the use of strips instead of nickel and stainless steel sheets is intended to save material by not using materials, since strips are used as binders and only non-welded parts are binder-free parts. This is because there is an advantage that can significantly reduce its own weight.
[실시예]EXAMPLE
제 1 도에 나타난 바와 같이 두께가 6.0mm인 탄소강판(1)의 편면위에 두께가 0.05-0.3mm인 닉켈박판(2) 또는 닉켈스트립, 스텐레스박판, 스텐네스 스트립을 가접한 다음 두께가 1.6mm인 닉켈합금판(3)을 포개어 놓고 저항심용접을 행하였다.As shown in FIG. 1, a nickel plate (2) having a thickness of 0.05-0.3 mm or a nickel plate, a stainless plate, and a stainless strip are welded on one side of a carbon steel sheet 1 having a thickness of 6.0 mm, and then 1.6 mm thick. The nickel nickel alloy plate 3 was piled up and resistance welding was performed.
저항심용접 간격은 용도 및 설계강도 요구에 따라 최소 10mm에서 최대 200mm간격으로 수행하는 것이 가능하며, 이때 발생되는 심비드(4)의 모양이 도면에 도시되어 있다.The resistance seam spacing may be performed at intervals of at least 10 mm and at most 200 mm, depending on the application and design strength requirements, and the shape of the seam bead 4 generated at this time is shown in the drawings.
이와 같이 제조된 클래드판과 종래방법으로 제조된 클래드판의 기계적성질을 비교한 값이 다음표에 나타나있다.The values of comparing the mechanical properties of the clad plate thus prepared and the clad plate manufactured by the conventional method are shown in the following table.
[표 1]TABLE 1
표 1에서 보듯이 닉켈합금판과 탄소강판 사이의 바인더를 선택하는데 따라 상당한 기계적 성질의 차이를 발견할 수 있으며 종래의 스텐레스망, 구리망 및 구리박판 바인더를 사용한 것보다는 본 발명의 스텐레스박판이, 스텐레스 박판보다는 닉켈박판을 사용하는 것이 우수한 기계적 성질 결과를 얻을 수 있다는 것을 알 수 있다.As shown in Table 1, a considerable difference in mechanical properties can be found by selecting a binder between the nickel alloy sheet and the carbon steel sheet, and the stainless steel sheet of the present invention, rather than using the conventional stainless steel mesh, copper mesh and copper foil binder, It can be seen that the use of nickel plate rather than stainless steel plate can result in excellent mechanical properties.
본 발명에 따르면 강재 및 닉켈합금판과 결합력이 우수한 스텐레스박판, 닉켈박판을 바인더로 사용하므로서 인장강도, 전단강도, 박리강도 등 기계적 성질이 우수한 닉켈합금기 클래드판의 제조가 가능하며, 설계강도 및 사용조건에 따라 바인더를 스텐레스박판, 스텐레스 스트립, 닉켈박판, 닉켈스트립 등으로 선별하여 채택, 사용할 수 있어 닉켈합금기 클래드판을 저렴한 가격으로 제조하는 것이 가능하여 탈황설비 등의 제작 설치비를 절감할 수 잇는 효과가 있다.According to the present invention, by using the stainless steel plate and the nickel plate with excellent bonding strength with the steel and the nickel alloy plate as a binder, it is possible to manufacture the nickel plated clad plate with excellent mechanical properties such as tensile strength, shear strength, peeling strength, design strength and Depending on the conditions of use, the binder can be selected and used as stainless steel plate, stainless strip, nickle plate, nickle strip, etc., so that Nickel alloy clad plate can be manufactured at low price, thus reducing the manufacturing and installation cost of desulfurization equipment. There is a connection effect.
