Description
본 고안은 용강측온장치에 관한 것으로, 특히 팁(Tip)과 연결파이프 사이에 보상도선 단자가 내장되는 단자파이프를 설치하여 팁의 교환을 용이하게 할 수 있는 용강측온장치에 관한 것이다.The present invention relates to a molten steel temperature measuring device, and more particularly to a molten steel temperature measuring device that can facilitate the exchange of the tip by installing a terminal pipe with a built-in compensation wire terminal between the tip (Tip) and the connecting pipe.
제강조업에서 용강의 측온작업은 강의 품질에 큰 영향을 주는 요소로 정확한 온도측온이 필요하고, 용강온도를 측정하기 위하여 팁을 장착한 용강측정장치를 사용하게 된다.In steelmaking industry, temperature measurement of molten steel is a factor that greatly affects the quality of steel. Accurate temperature measurement is required, and a molten steel measuring device equipped with a tip is used to measure molten steel temperature.
이때, 도1 내지 도3에 도시한 바와같이 용강에 침적되어 용강의 적정온도를 측정하는 팁(25)에는 타르(Tar)가 발생되고, 팁에 전원을 공급하는 보상도상(23)에는 열화가 발생되어 측온시 그 측정정도가 떨어지는 문제점이 발생된다.At this time, as shown in Figs. 1 to 3, tar is generated in the tip 25 that is deposited in the molten steel to measure the proper temperature of the molten steel, and deterioration occurs in the compensation image 23 that supplies power to the tip. When the measurement occurs, the problem that the measurement accuracy falls.
따라서, 용강의 정확한 온도를 측정하기 위하여 주기적으로 팁(25)을 교체하게 되는데, 종래의 팁교환방법은 측온랜스(26)를 상승시킨 후, 고정핀(24)을 빼내어 연결파이프(22)로부터 팁(25)을 분리한다.Therefore, the tip 25 is periodically replaced to measure the accurate temperature of the molten steel. In the conventional tip exchange method, after raising the side temperature lance 26, the fixing pin 24 is pulled out from the connecting pipe 22. Remove the tip (25).
그리고, 팁(25)과 연결되는 보상도선(23)의 단자(14-1,14-2)를 공구를 이용하여 절단하고, 다시 측온랜스(26)를 하강시킨 후, 고정체(29)를 풀어 보상도선(23)를 밑으로 늘어 뜨린다.Then, the terminals 14-1 and 14-2 of the compensating wire 23 connected to the tip 25 are cut by using a tool, and the side temperature lance 26 is lowered again, and then the fixing body 29 is removed. Loosen the compensation wire 23 down.
여기서, 측온랜스(26)를 상승시키고, 하부로 늘어진 보상도선(23)의 단자(14-1,14-2)와 새로운 팁(25)의 단자를 연결한 후, 측온랜스(26)를 하강시킨 상태에서 늘어진 보상도선(23)을 위로 잡아당겨 고정체(29)로 고정시킨다.Here, the side temperature lance 26 is raised, the terminals 14-1 and 14-2 of the compensating lead line 23 extending downward and the terminals of the new tip 25 are connected, and then the side temperature lance 26 is lowered. Pulled up the compensating wire 23 is pulled up in the fixed state (29).
이때, 보상도선(23)이 위로 당겨지면서 보상도선과 연결된 팁(25)도 연결파이프(22)의 하부에 삽입되고, 다시 측온랜스(26)를 상승시킨 다음, 고정핀(24)을 끼워 연결파이프에 팁을 고정시킨 후, 내열플라스틱(4)과 팁캡(3)을 끼우면 팁교환작업이 완료된다.At this time, as the compensation wire 23 is pulled upward, the tip 25 connected to the compensation wire is also inserted into the lower portion of the connection pipe 22, and the side temperature lance 26 is raised again, and then the fixing pin 24 is inserted to connect the tip 25. After fixing the tip to the pipe, inserting the heat-resistant plastic (4) and the tip cap (3) is completed tip replacement.
이러한 종래의 팁교환작업은 조업대기상태에서만 작업을 해야하는 시간적 제약을 받고, 측온랜스 및 보상도선을 늘리고 당기는 등의 작업이 번거로울 뿐만아니라 작업시간이 과다하게 소요되며, 고소작업에 의한 안전사고의 위험도 있다.Such a conventional tip exchange work is time-limited to work only in the standby state, and it is not only cumbersome to increase and pull the side temperature lance and the compensation wire, but also takes too much work time, and the risk of safety accidents caused by aerial work. have.
본 고안은 팁(Tip)과 연결파이프 사이에 보상도선 단자가 내장되는 단자파이프를 연결하여 팁의 교환을 용이하게 할 수 있는 용강측온장치를 제공함에 그 목적이 있다.The object of the present invention is to provide a molten steel temperature measuring device that can facilitate the exchange of the tip by connecting a terminal pipe having a built-in compensation wire terminal between the tip (Tip) and the connecting pipe.

이때, 절연고무체(12-1)는 단자파이프(16)의 외주면 상단을 지름방향으로 관통하는 고정핀(13-1)에 의해 지지 고정되어 있다.At this time, the insulating rubber body 12-1 is supported and fixed by a fixing pin 13-1 penetrating the upper end of the outer circumferential surface of the terminal pipe 16 in the radial direction.
또한, 절연고무체(12-1)에는 그 하면 중앙과 일측에 각각 홈(20,20-1)이 형성되어 있고, 중앙홈(20)에 내장되면서 하부측이 돌출되도록 설치되는 ＋단자봉(17)은 압축스프링(19)에 의해 상하 탄성이동을 하면서 스토퍼(17-1)가 중앙홈의 걸림턱에 걸리도록 형성되어 있다.In addition, in the insulating rubber body 12-1, grooves 20 and 20-1 are formed at the center and one side of the lower surface thereof, respectively, and the + terminal rods are installed to protrude from the lower side while being embedded in the center groove 20. 17 is formed so that the stopper 17-1 is caught by the locking jaw of the central groove while the elastic spring is moved up and down by the compression spring 19.
여기서, ＋단자봉(17)보다 상대적으로 작게 형성되는 －단자봉(18)은 일측홈(20-1)에 내장되면서 압축스프링(19-1)에 의해 상하 탄성이동을 하게 되고, 하부측이 일측홈(20-1)의 하부로 돌출되도록 설치되어 있다.Here, the -terminal rod 18, which is formed relatively smaller than the + terminal rod 17, is embedded in one side groove 20-1, and is moved up and down elastically by the compression spring 19-1. It is installed to protrude to the lower side of the one side groove (20-1).
그리고, ＋단자봉(17)과 －단자봉(18)은 각각 단자(14-1,14-2)에 의해 보상도선(23)에 연결되어 있다.The + terminal rod 17 and the-terminal rod 18 are connected to the compensation lead 23 by terminals 14-1 and 14-2, respectively.
한편, 상단부가 단자파이프(16)의 하부측에 삽입되는 팁(25-1)은 팁단자파이프(7)와 팁캡(3)으로 구성되는데, 팁단자파이프(7)는 외주면 중단에 지름방향의 지지핀(8)이 고정 부착되어 있고, 이 지지핀(8)은 각각 지지홈(16-1,16-2)에 끼워져 팁단자파이프를 지지하게 된다.On the other hand, the tip 25-1 having the upper end inserted into the lower side of the terminal pipe 16 is composed of a tip terminal pipe 7 and a tip cap 3, the tip terminal pipe 7 in the radial direction to the outer peripheral surface interruption. The support pin 8 is fixedly attached, and the support pin 8 is fitted into the support grooves 16-1 and 16-2, respectively, to support the tip terminal pipe.
그리고, 팁단자파이프(7)에는 절연플라스틱(10)에 의해 그 내주면과 절연되도록 －단자링(5-2)이 내장되어 있고, 이 －단자링(5-2)에는 절연플라스틱에 의해 그 내주면과 절연되도록 ＋단자링(5-1)이 내장되어 있다.The tip terminal pipe 7 has a terminal ring 5-2 built therein so as to be insulated from the inner circumferential surface thereof by the insulating plastic 10, and the inner terminal surface 5-2 is formed by the insulating plastic.

이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.
본 고안에 따른 용강측온장치는 팁교환시 팁단자파이프(7)를 약간 위로 들어올린 후, 우측방향으로 돌린 다음 놓으면 지지핀(8)이 지지홈(16-1,16-2)으로부터 빠져 나오게 된다.In the molten steel temperature measuring apparatus according to the present invention, the tip terminal pipe 7 is slightly lifted up when the tip is exchanged, and then turned to the right and then released so that the support pins 8 come out of the support grooves 16-1 and 16-2. do.
이렇게 단자파이프(16)로부터 분리된 팁(25-1)은 그 소손여부 또는 타르부착 등을 육안으로 확인할 수 있고, 소손에 의해 재사용이 불가능할 경우 새로운 팁으로 교체되지만 단순히 타르부착시 세척 후 재사용이 가능하다.Thus, the tip 25-1 separated from the terminal pipe 16 can be visually checked for burnout or tar attachment, and can be replaced with a new tip if it cannot be reused due to burnout. It is possible.
그리고, 팁(25-1)을 단자파이프(16)의 하부측에 끼우고자할 경우, 지지핀(8)을 지지홈(16-1,16-2)을 따라 상승시킨 후, 왼쪽방향으로 돌린 다음, 놓으면 지지핀은 지지홈의 내측에 안착된다.When the tip 25-1 is to be inserted into the lower side of the terminal pipe 16, the support pin 8 is raised along the support grooves 16-1 and 16-2, and then leftward. After turning, when released, the support pins rest on the inside of the support grooves.
따라서, 팁단자파이프(7)는 단자파이프(16)의 하부측에 지지핀(8)에 의해 지지되도록 삽입되고, 동시에 ＋단자봉(17)과 －단자봉(18)은 ＋단자링(5-1)과 －단자링(5-2)의 상면에 각각 탄성 밀착되어 팁(25-1)에 보상도선(23)의 전원을 인가하게 된다.Accordingly, the tip terminal pipe 7 is inserted to be supported by the support pin 8 on the lower side of the terminal pipe 16, and at the same time, the + terminal rod 17 and the-terminal rod 18 are + terminal rings 5 The upper surface of the -1) and -terminal ring 5-2 is elastically in contact with each other to apply the power of the compensating wire 23 to the tip 25-1.
본 고안은 팁(Tip)과 연결파이프 사이에 보상도선 단자가 내장되는 단자파이프를 연결함으로써 팁의 교환을 용이하게할 뿐만아니라 안전사고를 예방할 수 있는 효과를 제공하게 된다.The present invention not only facilitates tip exchange but also prevents safety accidents by connecting a terminal pipe having a built-in compensation wire terminal between the tip and the connection pipe.
