In order to establish, electrolytic decomposition in an iron salt bath aqueous solution (electrolyte solution) is used.

전해분해는 전해액 중에 강 시료와 음극판을 침적시키고, 강 시료에는 (＋) 전원을, 음극판에는 (－) 전원을 연결하여 직류전원을 통전시키면 전해가 시작된다.In electrolytic decomposition, a steel sample and a negative electrode plate are deposited in an electrolyte solution, electrolysis is started by energizing a DC power source by connecting a positive power source to the steel sample and a negative power source to the negative electrode plate.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명한다. 도면들 중 동일한 구성요소들은 가능한 어느 곳에서든지 동일한 부호로 표시한다. 또한 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like elements in the figures are denoted by the same reference numerals wherever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

도 1은 본 발명의 강 개재물 포집장치를 나타낸 도면으로서, 본 발명의 강 개재물 포집장치는 포집용기(10), 자력부여수단(20), 진동부여수단(30) 및 포집판(40)을 포함할 수 있다.1 is a view showing a steel inclusion collecting device of the present invention, the steel inclusion collecting device of the present invention includes a collecting container 10, magnetic force supply means 20, vibration imparting means 30 and the collecting plate 40. can do.

포집용기(10)는 바닥이 굽 형태를 이루는 사발 모양으로 형성되어 강 개재물을 함유하는 증류수를 담는다.The collection container 10 is formed in a bowl shape having a bottomed heel shape to contain distilled water containing steel inclusions.

중성 전해 추출장치에서 추출된 강 개재물은 중성 전해액에 섞여 있고, 이 중성 전해액을 멤브레인 필터를 갖는 분리장치에 넣고 진공을 만들면 전해액은 빠져 나가고 필터에 강 개재물이 남게 된다. 이 필터를 증류수가 담긴 비이커에 넣은 후 초음파 세척기에서 강 개재물을 증류수로 털어내면, 강 개재물을 함유하는 증류수가 얻어진다.The steel inclusions extracted from the neutral electrolytic extraction apparatus are mixed with the neutral electrolyte, and when the neutral electrolyte is put into a separator having a membrane filter, the vacuum is removed and the steel inclusions remain in the filter. The filter is placed in a beaker containing distilled water and the steel inclusions are shaken with distilled water in an ultrasonic cleaner to obtain distilled water containing the steel inclusions.

포집용기(10)는 강 개재물을 함유하는 증류수를 담은 상태에서 전기로에 넣어져 증류수를 증발시킴으로써 강 개재물을 포집한다. 포집용기(10)는 바닥으로 갈수록 직경이 좁아지도록 테이퍼지게 형성되어 강 개재물이 바닥에 효과적으로 포집되도록 한다.The collection container 10 is put into an electric furnace in the state containing distilled water containing the steel inclusions to collect the steel inclusions by evaporating distilled water. The collecting container 10 is tapered so that the diameter becomes narrower toward the bottom so that the steel inclusions are effectively collected on the bottom.

자력부여수단(20)은 포집용기(10)의 외주연에 1개 이상으로 배열 설치되며, 자력을 부여함으로써 전해분리 즉, 추출과정에서 생성되는 철부산물을 흡착하여 제거하도록 한다.The magnetic force applying means 20 is installed at least one on the outer periphery of the collection container 10, by applying a magnetic force to adsorb and remove the iron by-products generated in the electrolytic separation, that is, the extraction process.

자력부여수단(20)은 자석(영구자석 등) 또는 전자석 등 중 어느 하나로 이루지며, 포집용기(10)의 내벽면에 자성을 부여하여 철부산물을 포집용기(10)의 내벽면에 흡착시켜 제거함으로써, 포집용기(10)의 바닥에 순도 높은 강 개재물만이 포집되도록 한다.Magnetic imparting means 20 is made of any one of a magnet (permanent magnet, etc.) or an electromagnet, etc., by giving magnetism to the inner wall surface of the collecting container 10 by adsorbing iron by-products on the inner wall surface of the collecting container 10 removed. By doing so, only high purity steel inclusions are collected at the bottom of the collection container 10.

진동부여수단(30)은 포집용기(10)의 아래에 위치하여 포집용기(10)에 진동을 부여한다. 진동부여수단(30)은 증류수가 증발됨으로써 남은 강 개재물이 포집용기(10)의 내벽면에 붙지 않도록 하여 철부산물을 제외한 모든 강 개재물이 포집용기(10)의 바닥에 효과적으로 모이도록 한다.Vibration imparting means 30 is located below the collection container 10 to impart vibration to the collection container (10). The vibration imparting means 30 prevents the remaining steel inclusions from sticking to the inner wall surface of the collection container 10 by distilled water so that all steel inclusions except the iron by-products are effectively collected at the bottom of the collection container 10.

예컨대, 진동부여수단(30)은 내부가 빈 구조의 하우징(31)과, 하우징(31)의 내부에 장착되는 진동모터(33)로 이루어져, 진동모터(33)가 하우징(31) 위에 올려진 포집용기(10)에 미세한 진동을 부여함으로써, 강 개재물이 포집용기(10)의 내벽면에 붙지 않고 바닥에 모이도록 한다.For example, the vibration imparting means 30 is composed of a housing 31 having a hollow structure and a vibration motor 33 mounted inside the housing 31, so that the vibration motor 33 is mounted on the housing 31. By imparting a small vibration to the collection container 10, the steel inclusions do not adhere to the inner wall surface of the collection container 10 to be collected on the floor.

도 2에 도시된 바와 같이, 포집판(40)은 포집용기(10)의 바닥에 설치되어 강 개물의 포집장소를 마련한다. 포집용기(10)는 포집판(40)을 꺼낼 수 있도록 장착하며, 강 개재물이 포집된 포집판(40)은 SEM시편으로 사용되어 강 개재물의 정량분석 및 입도분포분석 등이 효과적으로 이루어지도록 한다.As shown in FIG. 2, the collecting plate 40 is installed at the bottom of the collecting container 10 to provide a collecting place of the steel piece. The collecting container 10 is mounted to take out the collecting plate 40, and the collecting plate 40 in which the steel inclusions are collected is used as an SEM specimen so that the quantitative analysis and the particle size distribution analysis of the steel inclusions are effectively performed.

도 3에 도시된 바와 같이, 예컨대, 포집용기(10)의 바닥은 뻥 뚫린 구멍 형태로 이루어질 수 있고, 캡(50)이 나사결합방식 등을 통해서 분리되게 결합됨으로써 바닥을 막아 포집판(40)을 꺼낼 수 있게 설치할 수 있고, 포집용기(10)로부터 캡(50)이 분리되면 캡(50)에 담긴 상태로 포집판(40)이 빠져 나옴으로써, 강 개재물의 손실을 최대한 줄이면서 주변의 오염 없이 분석할 수 있다.
As shown in Figure 3, for example, the bottom of the collection container 10 may be formed in the form of a hole drilled, cap 50 is coupled to be separated by a screw coupling method or the like to prevent the bottom of the collecting plate 40 When the cap 50 is separated from the collecting container 10, the collecting plate 40 is pulled out while being contained in the cap 50, thereby reducing the loss of steel inclusions and causing contamination of the surroundings. Can be analyzed without

상술한 바와 같이 본 발명은 전해분해 추출 후 강 개재물의 손실을 최대한 줄이면서 주변의 오염 없이 볼 수 있도록 함으로서, 추출 실험의 신뢰성을 높이고, 분석에 필요한 시간을 절감시킬 수 있다.As described above, the present invention can reduce the loss of the steel inclusions after the electrolytic extraction to maximize the reliability of the extraction experiment and reduce the time required for the analysis by allowing the environment to be viewed without contamination.

종래에는 증류수를 증발접시에 담아 건조시키고, 증발접시에 남은 강 개재물을 현미경으로 보면서 붓으로 찍어 SEM시편에 옮기거나 카본 테이프를 직접 증발접시에 접촉하여 강 개재물을 SEM시편에 부착시켰는데, 전자의 경우 시간이 많이 소모되고 형상이 부셔질 수 있으며, 후자의 경우 강 개재물이 붙지 않은 경우 분석이 어렵고 붙었다 해도 대표성이 떨어지기 때문에 신뢰성에 문제가 있는데, 본 발명은 모든 강 개재물을 포집하여 분석이 가능하므로 추출 실험의 신뢰성이 높고, 포집판(40)을 그대로 SEM시편으로 사용하기 때문에 분석에 필요한 시간을 절감할 수 있다.
Conventionally, distilled water was placed in an evaporating dish and dried, and the steel inclusions remaining on the evaporating dish were taken with a brush while looking under a microscope and transferred to the SEM specimen, or carbon tape was directly attached to the evaporating dish to attach the steel inclusions to the SEM specimen. In this case, a lot of time may be consumed and the shape may be broken. In the latter case, if the steel inclusions are not attached, the analysis is difficult and the representativeness is inferior even if they are attached. However, the present invention may collect and analyze all steel inclusions. Therefore, the reliability of the extraction experiment is high, and since the collecting plate 40 is used as the SEM specimen, time required for analysis can be reduced.
