Description

전기로의 전극스프레이{electrode spray for electric furnace}Electrode spray for electric furnace

본 고안은 전기로의 전극스프레이에 관한 것으로, 특히 전극스프레이의 변형 및 파손을 방지하여 전극봉의 냉각성능을 향상시킬 수 있도록 된 전기로의 전극스프레이에 관한 것이다.The present invention relates to an electrode spray of an electric furnace, and more particularly to an electrode spray of an electric furnace to prevent deformation and breakage of the electrode spray to improve the cooling performance of the electrode.

일반적으로 제철공정에서 이용되는 전기로는 고철이 주입되는 노(爐)와, 고철 용해시 노의 상부를 덮어 외부와 차단하는 커버 및 상기 커버를 관통하여 단부가 노의 안쪽에 위치하도록 설치됨으로써 전력 공급시 고철과의 사이에 아크를 방전시켜 고열을 발생시키는 전극봉으로 이루어진다.In general, the electric furnace used in the steelmaking process is supplied with a furnace in which scrap metal is injected, a cover which covers the upper part of the furnace during melting of the scrap metal and blocks it from the outside, and is installed so that the end part is located inside the furnace through the cover. It consists of an electrode that generates high heat by discharging an arc between the scrap metal and the city.

또한, 상기 노의 안쪽은 내화벽돌이 적층되어 단열층을 형성하고, 바깥쪽은 두터운 철판으로 형성되어 외형을 이루고 있다.In addition, the inside of the furnace is laminated with refractory bricks to form a heat insulating layer, the outside is formed of a thick iron plate to form an appearance.

그리고, 상기 노와 커버에는 모두 내부에 냉각수 배관이 설치되어 있어서 집수조로부터 냉각수 펌프에 의해 냉각수가 공급/순환되며, 열교환 후 배출된 냉각수는 냉각탑에서 냉각되어 다시 집수조로 모이도록 되어 있다.In addition, both the furnace and the cover are provided with a cooling water pipe therein, so that the cooling water is supplied / circulated from the collection tank by the cooling water pump, and the cooling water discharged after the heat exchange is cooled in the cooling tower and collected again in the collection tank.

따라서, 전기로 과열에 의한 파손을 방지하고 외부로의 열방출량을 감소시키고 있다.Therefore, the damage caused by overheating of the electric furnace is prevented and the amount of heat released to the outside is reduced.

한편, 상기 전극봉은 아크열에 의해 가열된 상태에서 대기와 접촉하여 산화/소모되는데, 이러한 소모현상은 전극봉의 온도가 높을수록 증대되기 때문에 전극봉의 수명 증대를 위하여 전극봉의 냉각이 필요하게 된다.On the other hand, the electrode is oxidized / consumed in contact with the atmosphere in the heated state by the arc heat, this consumption phenomenon is increased as the temperature of the electrode increases, it is necessary to cool the electrode to increase the life of the electrode.

전극봉의 냉각은 도 1에 도시된 바와 같이, 전극봉(3)을 감싸는 스테인리스 재질의 전극스프레이(10)를 설치하고, 전극스프레이(10)에 냉각수배관을 연결하여, 전극스프레이(10)로부터 전극봉(3) 표면으로 냉각수를 분사함으로써 냉각이 이루어지도록 되어 있다.As shown in FIG. 1, the cooling of the electrode rod is made by installing an electrode spray 10 made of stainless steel that surrounds the electrode rod 3, connecting a cooling water pipe to the electrode spray 10, and removing the electrode rod from the electrode spray 10. 3) Cooling is achieved by spraying coolant onto the surface.

상기 전극스프레이(10)는 도시된 바와 같이 전극봉(3)의 둘레 외측을 둘러싸는 원형관부(11)와 상기 원형관부(11)의 일측에 연결되어 커넥터(13)를 통해 냉각수 공급배관에 연결되는 직선관부(12)으로 이루어진다. 이때 상기 원형관부(11)는 공급된 냉각수가 역류하는 것을 방지하기 위하여 중간 부분이 상호 분리 성형되어 있다.The electrode spray 10 is connected to one side of the circular tube portion 11 and the circular tube portion 11 surrounding the outer circumference of the electrode rod 3, as shown, is connected to the cooling water supply pipe through the connector 13 It consists of a straight pipe part 12. At this time, the circular tube portion 11 is formed in the middle portion is separated from each other in order to prevent the flow of the supplied cooling water back.

그리고, 상기 원형관부(11)의 하면에는 원주 방향 전체에 걸쳐 일정 간격마다 분사공(14)이 형성되어 있다.The lower surface of the circular tube portion 11 is provided with injection holes 14 at regular intervals over the entire circumferential direction.

따라서, 전극봉(3)의 둘레 외측을 상기 원형관부(11)가 둘러싸도록 설치한 후 냉각수를 공급하면 상기 분사공(14)을 통해 냉각수가 전극봉(3)의 표면으로 분사되어 냉각수가 전극봉(3)의 표면을 타고 흘러내리면서 증발되어 전극봉(3)의 냉각이 이루어지도록 되어 있었다.Therefore, when the circular pipe part 11 is installed so as to surround the outer side of the electrode 3, when the cooling water is supplied, the cooling water is injected to the surface of the electrode 3 through the injection hole 14, and the cooling water is discharged to the electrode 3. It was evaporated while flowing down the surface of the electrode) to cool the electrode 3.

그런데, 상기 전극스프레이(10)는 전술한 바와 같이 중간 부분이 상호 분리 성형되어 있어서 내부를 흐르는 냉각수와 상면에 퇴적되는 스케일의 하중에 의하여 상기 원형관부(11)의 한쪽 또는 양쪽 부분 모두가 하방으로 처지는 현상이 발생하였다. 이러한 현상은 전극봉(3)에 발생하는 고열에 의한 영향을 받아 더욱 심해진다.However, as described above, the electrode spray 10 has an intermediate portion formed separately from each other so that one or both portions of the circular pipe portion 11 are moved downward by a load of a cooling water flowing inside and a scale deposited on the upper surface. Sagging occurred. This phenomenon is further affected by the high heat generated in the electrode 3.

상기와 같이 원형관부(11)의 어느 한쪽에 처짐이 발생하면 피로 누적에 의해 결국 처짐이 발생한 원형관부(11)에 크랙(C1)이 발생하고, 원형관부(11)의 양쪽 모두에 처짐이 발생하면 직선관부(12)에 크랙(C2)이 발생하여 냉각수가 누출되며, 이에 상기 분사공(14)을 통한 정상적인 냉각수 분사가 이루어지지 않으므로 전극봉(3) 냉각성능이 저하된다.If deflection occurs in any one of the circular tube portions 11 as described above, cracks C1 are generated in the circular tube portion 11, which eventually causes deflection due to accumulation of fatigue, and sag occurs in both of the circular tube portions 11. If the crack (C2) is generated in the straight tube portion 12, the cooling water leaks, and since the normal cooling water is not injected through the injection hole 14, the cooling performance of the electrode rod 3 is lowered.

따라서, 전극스프레이(10)를 자주 교체해야 할뿐만 아니라 전극봉(3)의 교체주기도 빨라지게 되므로 교체비용과 시간이 소모되는 문제점이 있었다.Therefore, not only the electrode spray 10 needs to be replaced frequently, but also the replacement cycle of the electrode rod 3 becomes faster, thereby causing a problem in that replacement cost and time are consumed.

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 전극스프레이의 처짐을 방지하여 처짐과 고열의 영향으로 인한 크랙 발생을 억제함으로써 전극스프레이 자체의 수명이 연장되고, 정상적인 냉각수 분사를 통해 전극봉의 냉각성능이 향상되므로 전극봉의 수명 또한 연장될 수 있도록 된 전기로의 전극스프레이를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, by preventing the deflection of the electrode spray to suppress the occurrence of cracks due to the effects of sagging and high heat to extend the life of the electrode spray itself, the electrode rod through the normal cooling water spray The purpose of the present invention is to provide an electrode spray of an electric furnace, in which the cooling performance of the electrode is improved, so that the life of the electrode can be extended.

상기와 같은 목적을 달성하기 위한 본 고안은,The present invention for achieving the above object,

전극봉을 둘러싸는 원형관부와, 그 원형관부에 연결되어 커넥터를 매개로 냉각수 공급배관에 연결되는 직선관부로 이루어진 전기로의 전극스프레이에 있어서,In the electrode spray of the electric furnace consisting of a circular pipe portion surrounding the electrode rod and a straight pipe portion connected to the circular pipe portion and connected to the cooling water supply pipe via a connector,

상기 원형관부가 이격된 부분 없이 완전한 원형체로 이루어진 것을 특징으로 한다.The circular tube portion is characterized in that consisting of a complete circular body without the spaced apart portion.

상기 원형관부의 내부에는 격벽이 설치되어 좌우 부분이 구획된다.A partition wall is installed inside the circular pipe part to partition the left and right parts.

상기 직선관부는 마운팅브라켓으로 전극봉홀더에 장착되는 상부수평관부와, 이 상부수평관부에서 하방으로 절곡 연장된 연결관부와, 이 연결관부에서 수평으로 절곡 연장되어 상기 원형관부에 연결되는 하부수평관부로 이루어진다.The straight pipe part is an upper horizontal pipe part mounted to the electrode holder by a mounting bracket, a connecting pipe part bent downward from the upper horizontal pipe part, and a horizontal horizontal part bent horizontally extending from the connecting pipe part and connected to the circular pipe part. Is done.

상기와 같은 구성으로 이루어진 본 고안에 따르면, 전극스프레이의 처짐 변형이 방지되고, 이에 전극스프레이의 크랙 발생을 방지할 수 있게 되므로 전극스프 레이의 수명이 연장되는 효과가 있다.According to the present invention having the above configuration, the deflection deformation of the electrode spray can be prevented, and thus cracking of the electrode spray can be prevented, thereby extending the life of the electrode spray.

또한, 전극스프레이의 크랙 발생이 방지되어 냉각수가 정상 압력으로 전극봉 표면에 분사되므로 전극봉 냉각 성능이 향상되어 전극봉의 수명도 연장되는 효과가 있다.In addition, since the occurrence of cracks in the electrode spray is prevented and the cooling water is injected to the electrode surface at a normal pressure, the electrode cooling performance is improved, thereby extending the life of the electrode.

따라서, 상기 전극스프레이와 전극봉의 교체에 소요되는 시간과 비용을 절감할 수 있게 되는 효과가 있다.Therefore, there is an effect that it is possible to reduce the time and cost required to replace the electrode spray and electrode.

이하, 본 고안을 첨부된 예시도면을 참조하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 2는 본 고안에 따른 전극스프레이를 도시한 것으로, (a)는 설치 상태도, (b)는 원형관부의 부분 단면도, (c)는 평면도이다.Figure 2 shows an electrode spray according to the present invention, (a) is an installation state diagram, (b) is a partial cross-sectional view of the circular tube portion, (c) is a plan view.

도시된 바와 같이 전극스프레이(10)는 전극봉(3)을 둘러싸는 원형관부(11)와, 그 원형관부(11)에 연결되어 커넥터(13)를 매개로 냉각수 공급배관에 연결되는 직선관부(12)로 이루어진다.As shown in the drawing, the electrode spray 10 includes a circular pipe portion 11 surrounding the electrode rod 3 and a straight pipe portion 12 connected to the circular pipe portion 11 and connected to the cooling water supply pipe via the connector 13. )

상기 직선관부(12)는 전극봉홀더(20)의 하측면 또는 내부에 마운팅브라켓(30)을 매개로 장착된다.(볼트체결)The straight pipe portion 12 is mounted on the lower side or inside of the electrode rod holder 20 via a mounting bracket 30. (Bolt fastening)

상기와 같은 전극스프레이(10)에 있어서, 본 고안은, 상기 원형관부(11)가 이격된 부분 없이 완전한 원형으로 이루어진 것을 특징으로 한다.In the electrode spray 10 as described above, the subject innovation is characterized in that the circular tube portion 11 is formed in a complete circle without spaced apart portions.

따라서, 원형관부(11)의 어느 한쪽 부분에 상대적으로 많은 양의 냉각수가 유입되거나 또는 어느 임의의 부분 상면에 많은 양의 스케일이 퇴적될지라도 원형관부(11)의 좌우 부분(도면상 중심선을 기준으로 상하부분) 전체가 일체로 작용하 기 때문에 원형관부(11)의 직선관부(12) 근접 부분에 변형(처짐) 및 크랙(C1)이 발생하지 않게 된다.Therefore, even if a relatively large amount of coolant flows into one portion of the circular tube portion 11 or a large amount of scale is deposited on the upper surface of any arbitrary portion, the left and right portions of the circular tube portion 11 (based on the center line in the drawing) Since the entire upper and lower portions act integrally, the deformation (sag) and crack (C1) does not occur in the vicinity of the straight tube portion 12 of the circular tube portion (11).

이때 상기 원형관부(11)의 내부(상기 중심선 위치)에는 격벽(15)이 설치되어 원형관부(11)의 좌우 부분을 구획함으로써 종래와 같이 상호 분리되어 냉각수의 역류를 방지할 수 있게 된다.At this time, the partition wall 15 is installed inside the circular pipe portion 11 (the center line position) to partition the left and right portions of the circular pipe portion 11 to be separated from each other as in the prior art to prevent the reverse flow of the cooling water.

즉, 상기 원형관부(11)는 하중의 작용은 일체로 받도록 하고, 냉각수의 흐름은 종래와 같이 좌우 부분이 독립적으로 이루어지도록 하는 것이다.That is, the circular pipe portion 11 is to receive the action of the load integrally, the flow of the cooling water is to be made independently of the left and right parts as in the prior art.

한편, 상기 직선관부(12)는 마운팅브라켓(30)을 매개로 전극봉홀더(20)의 하측면에 장착되는 상부수평관부(12a)와, 이 상부수평관부(12a)에서 하방으로 절곡 연장된 연결관부(12b)와, 이 연결관부(12b)에서 다시 수평으로 절곡되어 상기 원형관부(11)에 연결되는 하부수평관부(12c)로 이루어진다.On the other hand, the straight pipe portion 12 is connected to the upper horizontal pipe portion 12a which is mounted on the lower side of the electrode rod holder 20 via the mounting bracket 30, and bent downward from the upper horizontal pipe portion 12a It consists of a pipe part 12b and a lower horizontal pipe part 12c which is bent horizontally again in this connecting pipe part 12b and connected to the circular pipe part 11.

즉, 상기 직선관부(12)는 중간 부분이 직각으로 2회 절곡되어 단차가 형성된 수평관 구조로 이루어져 있다.That is, the straight pipe portion 12 has a horizontal pipe structure in which a step is formed by bending a middle portion twice at a right angle.

따라서, 단순한 직선관 형태일 때보다 하방으로의 굽힘하중에 대한 대응 강성이 향상되어 크랙(C2)의 발생이 억제된다.Therefore, the corresponding rigidity with respect to the bending load downward is improved compared with the case of the simple straight tube form, and generation | occurrence | production of crack C2 is suppressed.

상기 직선관부(12)의 굽힘하중에 대한 대응강성은 상기 하부수평관부(12c)의 길이 즉, 원형관부(11)로부터 상기 연결관부(12b)까지의 길이와, 상기 연결관부(12b)로부터 마운팅브라켓(30) 장착지점 까지의 거리를 짧게 할수록 증가하게 되며, 이 경우 직선관부(12)의 크랙(C2) 발생은 더욱 효과적으로 방지된다.The corresponding stiffness to the bending load of the straight pipe part 12 is the length of the lower horizontal pipe part 12c, that is, the length from the circular pipe part 11 to the connection pipe part 12b, and mounting from the connection pipe part 12b. The shorter the distance to the mounting point of the bracket 30 is increased, in this case, the crack C2 of the straight pipe portion 12 is more effectively prevented.

이상과 같이 본 고안은 원형관부(11)가 분리된 부분 없이 완전한 하나의 원 형체로 형성되고, 직선관부(12)가 중간부분에 단차가 존재하는 직선관체로 형성되어 원형관부(11)와 직선관부(12)의 처짐 및 크랙(C1)(C2) 발생이 억제된다.As described above, the present invention is formed as a single circular body without a separate portion of the circular tube portion 11, and the straight tube portion 12 is formed as a straight tube body with a step in the middle portion, so that the circular tube portion 11 and the straight line are Deflection of the pipe part 12 and generation | occurrence | production of the crack C1 and C2 are suppressed.

따라서, 원형관부(11)의 좌우 양측 부분으로 냉각수가 균일하게 공급되고(어느 한쪽 부분이 처지지 않으므로) 크랙(C1,C2)을 통한 냉각수의 누수가 없어 분사압력이 정상적으로 형성되어 전극봉(3)의 전 둘레 표면에 냉각수가 충분히 고르게 분사되어 전극봉(3) 냉각성능이 향상되는 효과가 있다.Accordingly, the cooling water is uniformly supplied to both the left and right portions of the circular tube portion 11 (no one part sags), and there is no leakage of the cooling water through the cracks C1 and C2. Cooling water is sufficiently evenly sprayed on the circumferential surface of the electrode 3 has the effect of improving the cooling performance.

따라서, 상기 전극스프레이(10)와 전극봉(3)의 수명이 모두 늘어나게 되고, 이에 따라 이들의 교체주기가 길어짐으로써 교체로 인한 비용과 시간의 손실을 감소시킬 수 있게 되는 효과가 있다.Therefore, the lifespan of the electrode spray 10 and the electrode 3 is both increased, and thus the replacement cycle is longer, thereby reducing the cost and time lost due to the replacement.
