Description

용손 유입을 최소화하는 슈 블록{Show block which minimizes influx of melting}Shoe block to minimize the influx of melting hands {Show block which minimizes influx of melting}

본 발명은 용손 유입을 최소화하는 슈 블록에 관한 것으로, 더욱 상세하게는 슬래브의 스카핑 작업시 발생하는 용손의 유입을 최소화하여 스카핑 노즐의 사용수명 및 슬래브의 생산품질을 향상시킬 수 있도록 하는 용손 유입을 최소화하는 슈 블록에 관한 것이다.The present invention relates to a shoe block for minimizing the inflow of molten iron, and more particularly, to minimize the inflow of molten iron generated during the slapping of the slab to improve the service life of the scarfing nozzle and the production quality of the slab. A shoe block that minimizes ingress.

일반적으로 슈 블록은 슬래브의 표면에 형성된 이물질을 제거하기 위한 스카핑 노즐(1)에 포함된 구성으로, 도 1에 도시된 바와 같이 슬래브(A)의 표면과 예각으로 설치된 상태에서 혼합가스를 분사하여 슬래브(A)의 표면을 산세함으로써 산화스케일과 같은 이물질을 효과적으로 제거할 수 있다.In general, the shoe block is a configuration included in the scarfing nozzle 1 for removing the foreign matter formed on the surface of the slab, as shown in Figure 1 injecting the mixed gas in a state installed at an acute angle with the surface of the slab (A) By pickling the surface of the slab A, foreign matters such as an oxide scale can be effectively removed.

그러나 종래의 슈 블록(40)은 로우 블록(30)의 상부에 형성되어 슬래브(A)를 지정된 방향으로 유도하는 역할을 수행할 뿐, 슬래브(A)의 스카핑작업시 발생하는 용손이 어퍼 블록(20)과 로우 블록(30)의 선단부로 유입되는 문제를 방지할 수 없 는 기능상의 한계를 갖게 되었다.However, the conventional shoe block 40 is formed on the upper portion of the low block 30 to serve to guide the slab A in a predetermined direction, and the loss of the slab generated during the scarfing operation of the slab A is an upper block. (20) and the lower block 30 has a functional limit that can not prevent the problem flowing into the front end.

즉, 어퍼 블록(20)과 로우 블록(30)의 선단부로 용손이 유입될 경우 가스 및 산소의 분사공이 밀폐되므로, 이로 인해 혼합가스의 분사량이 일정하지 못해 슬래브의 표면에 형성된 이물질을 완벽하게 제거할 수 없는 문제점이 발생한다.That is, when the melt is introduced into the front end of the upper block 20 and the low block 30, the injection hole of the gas and oxygen is sealed, so that the injection amount of the mixed gas is not constant, thereby completely removing foreign substances formed on the surface of the slab. Unable problem occurs.

특히 슬래브(A)의 표면을 균일하게 산세할 수 없으므로 슬래브의 생산품질에 직접적인 영향을 초래하는 심각한 문제점을 갖게 되었다.In particular, since the surface of the slab (A) can not be pickled uniformly, there is a serious problem that directly affects the production quality of the slab.

또한, 용손이 유입된 어퍼 블록(20)과 로우 블록(30)은 재사용이 불가능하여 경제적인 비용이 가중됨은 물론 유지보수를 위해 전체적인 생산공정이 지연되는 문제점을 갖게 되었다.In addition, the upper block 20 and the low block 30 into which the dragon hand is introduced are not reusable, thereby increasing the economic cost and having the problem that the entire production process is delayed for maintenance.

따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서,Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art,

본 발명의 목적은 슈 블록의 선단부에 일정길이로 연장되는 용손 차단부를 형성하여 어퍼 블록 및 로우 블록의 선단부로 용손이 유입됨을 최소화함으로써, 스카핑 장치의 사용수명을 증대시킴은 물론 슬래브의 생산품질을 향상시킬 수 있도록 하는 용손 유입을 최소화하는 슈 블록을 제공함에 있다.It is an object of the present invention to minimize the inflow of molten iron into the tip of the upper block and the low block by forming a melt loss block extending to a predetermined length at the tip of the shoe block, thereby increasing the service life of the scarfing device as well as the slab production quality It is to provide a shoe block that minimizes the influx of solvents to improve the.

본 발명은 로우 블록(30)의 상부에 설치된 몸체(110)와; 상기 몸체(110)의 내부에 형성된 냉각수 순환관(120)과; 상기 몸체(110)의 상부에 형성된 다수의 스키드(130)와; 상기 몸체(110)의 선단에서 로우 블록(30)의 선단방향으로 혼합가스 분사각도와 간섭되지 않는 위치까지 연장되는 용손 차단부(140)를 포함하는 것을 특징으로 한다.The present invention and the body 110 is installed on the top of the row block 30; Cooling water circulation pipe 120 formed in the body 110; A plurality of skids 130 formed on an upper portion of the body 110; It characterized in that it comprises a melt loss block 140 extending from the tip of the body 110 to a position that does not interfere with the mixed gas injection angle in the tip direction of the low block 30.

본 발명은 슬래브의 산세과정에서 발생하는 용손이 어퍼 블록 및 로우 블록의 선단부로 유입됨을 최소화하여 혼합가스를 균일하게 분사할 수 있으므로 슬래브의 생산품질을 증대시킬 수 있는 효과를 갖는다.The present invention has the effect of increasing the production quality of the slab because it is possible to uniformly spray the mixed gas by minimizing the flow of the melt generated during the pickling process of the slab to the front end of the upper block and the low block.

또한, 본 발명은 용손의 유입을 최소화하여 스카핑 장치의 사용수명을 연장함은 물론 유지보수에 소요되는 비용을 절감하여 경제적인 이익을 창출할 수 있는 효과를 갖는다.In addition, the present invention has the effect of generating economic benefits by minimizing the influx of solvent loss to extend the service life of the scarfing device, as well as the cost of maintenance.

특히 본 발명은 구조가 간단할 뿐만 아니라 기존에 사용중인 스카핑 장치에 쉽게 적용할 수 있으므로 사용효율은 물론 활용범위를 향상시킬 수 있는 효과를 갖는다.In particular, the present invention has a simple structure and can be easily applied to the existing scarfing device, so that the efficiency of use can be improved as well as the use range.

상기한 바와 같은 본 발명의 목적을 달성하기 위한 기술적 구성을 첨부한 도면에 의해 설명하면 다음과 같다.Referring to the accompanying drawings, a technical configuration for achieving the object of the present invention as described above is as follows.

도 2는 본 발명 용손 유입을 최소화하는 슈 블록의 구조를 나타내기 위한 사시도이고, 도 3은 본 발명 용손 유입을 최소화하는 슈 블록의 구조를 나타내기 위한 측면도이며, 도 4는 본 발명 슈 블럭을 포함한 스카핑 장치의 작동상태를 나타내기 위한 참고도를 도시한 것이다.Figure 2 is a perspective view for showing the structure of the shoe block to minimize the influx of the present invention, Figure 3 is a side view for showing the structure of the shoe block to minimize the inflow of the present invention, Figure 4 is a shoe block of the present invention Reference is made to indicate the operating state of the scarfing device included.

본 발명에서 상기 몸체(110)는 스카핑 작업시 발생하는 고열이 스카핑 장치(1)의 헤드 블록(10) 및 로우 블록(30)으로 전달됨을 최소화하여 사용수명을 증대시킴은 물론 손상을 방지하는 역할을 수행한다.In the present invention, the body 110 minimizes the high heat generated during the scarfing operation to the head block 10 and the low block 30 of the scarfing device 1 to increase the service life and to prevent damage. It plays a role.

특히 상기 몸체(110)의 내부에는 냉각수 순환관(120)을 형성하여 스카핑 작업시 발생하는 고열 및 화염으로 인한 열변형을 최소화한다.In particular, the cooling water circulation pipe 120 is formed inside the body 110 to minimize thermal deformation due to high heat and flames generated during the scarfing operation.

이때 상기 냉각수 순환관(120)은 냉각효율의 극대화를 위해 상기 몸체(110) 의 내부를 가로 및 세로 방향으로 순환할 수 있도록 형성됨이 바람직하다.At this time, the cooling water circulation pipe 120 is preferably formed to circulate in the horizontal and vertical direction of the inside of the body 110 to maximize the cooling efficiency.

아울러 상기 몸체(110)의 상부에는 스키드(130)가 장착되어 통과하는 슬래브(A)의 표면과 맞닿아 원활하게 이동할 수 있도록 유도한다.In addition, the skid 130 is mounted on the upper portion of the body 110 to be in contact with the surface of the slab (A) passing through to guide to move smoothly.

이때 상기 스키드(130)의 장착위치 및 개수는 작업상황에 따라서 달라질 수 있음은 당연하다.At this time, the mounting position and the number of the skid 130 is a matter of course can vary depending on the working situation.

한편, 상기 용손 차단부(140)는 스카핑 작업시 발생하는 용손이 어퍼 블록(20)과 로우 블록(30)의 선단부로 유입됨을 최소화하기 위한 매우 중요한 구성이다.On the other hand, the melt loss block 140 is a very important configuration for minimizing the inflow of the melt generated during the scarfing operation to the front end of the upper block 20 and the low block 30.

즉, 도 4에 도시된 바와 같이 상기 몸체(110)의 선단부에서 상기 로우 블록(30)의 선단부를 향하도록 일정길이를 갖도록 연장된 상태이므로, 결과적으로 비산되는 용손이 상기 용손 차단부(140)와 맞닿아 차단되어 상기 어퍼 블록(20)과 로우 블록(30)의 선단부로 유입됨을 방지할 수 있다.That is, as shown in FIG. 4, since it extends to have a predetermined length from the leading end of the body 110 to the leading end of the row block 30, the resulting blemishes are scattered as the result of the bleeding block 140. It is blocked by contact with the upper block 20 and the low block 30 can be prevented from flowing into the front end portion.

이때 상기 용손 차단부(140)의 길이와 각도는 상기 몸체(110)의 선단에서 어퍼 블록(20)의 분사각도와 간섭되지 않는 각도와 위치까지 연장됨이 바람직하다.In this case, the length and the angle of the melt loss block 140 is preferably extended from the tip of the body 110 to an angle and a position that does not interfere with the injection angle of the upper block 20.

이처럼 상기와 같이 본 발명의 실시한 예에 대하여 상세히 설명하였으나, 본 발명의 권리범위는 이에 한정되지 않으며, 본 발명의 실시한 예와 실질적으로 균등의 범위에 있는 것까지 본 발명의 권리범위가 포함되는 것은 당연하다.As described above, the embodiment of the present invention has been described in detail, but the scope of the present invention is not limited thereto, and the scope of the present invention is included to the extent that the present invention is substantially equivalent to the embodiment of the present invention. Of course.
