Description
본 발명은 고온 소둔로 내의 대차 온도측정장치에 관한 장치로서, 보다 상세하게는 고온 소둔로 내의 대차 열전쌍(Thermocouple) 접촉단자와 수평타입으로 접촉 내지 단락하여 소둔중인 코일의 실제온도를 측정함과 동시에 실링 효과를 부여하는 고온 소둔로 내의 대차 온도측정장치에 관한 것이다.The present invention relates to a bogie temperature measuring apparatus in a high temperature annealing furnace. More specifically, the bore thermocouple contact terminal in a high temperature annealing furnace is contacted or short-circuited with a horizontal type to measure the actual temperature of the coil being annealed. The present invention relates to a bogie temperature measuring device in a high temperature annealing furnace that provides a sealing effect.
일반적으로 소둔로는 열연압연된 코일을 2차 재결정시키기 위한 열처리 장비로서, 소둔로의 내벽체에는 소둔로 내의 온도를 지속적으로 측정하기 위한 열전쌍(Thermocouple)이 설치되어 있다.In general, the annealing furnace is a heat treatment equipment for secondary recrystallization of the hot rolled coil, and an inner wall of the annealing furnace is provided with a thermocouple for continuously measuring the temperature in the annealing furnace.
이러한 열전쌍은 소둔로 내의 각 영역별로 설치되어 수시로 온도확인이 가능한 장점은 있지만 운전실에서 얻어진 온도정보는 코일 자체의 온도가 아니라 로 내의 분위기 가스의 온도이기 때문에 코일의 소둔온도 자체를 제어하여 온도가 코일에 미치는 영향을 제어하기는 곤란한 점이 있다.These thermocouples are installed for each area in the annealing furnace, so the temperature can be checked at any time. However, since the temperature information obtained from the cab is not the temperature of the coil itself but the temperature of the atmosphere gas in the furnace, the temperature is controlled by controlling the annealing temperature of the coil itself. It is difficult to control the effect on the system.
따라서, 소둔로 내의 분위기 온도가 코일에 미치는 영향을 알아보기 위하여 대한민국 실용출원 제98-027993호에 소둔로 내의 코일 실온 측정장치가 개시되어 있다.Therefore, in order to find out the effect of the ambient temperature in the annealing furnace on the coil, Korean Utility Application No. 98-027993 discloses a coil room temperature measuring apparatus in the annealing furnace.
도 1에 도시된 바와 같이, 종래의 소둔로(14) 내의 코일(1) 실온 측정장치는 소둔로(14)의 외벽에 코일(1) 대차(2)의 진행방향에 따라 슬라이딩 홈(5)이 오목하게 형성되며, 상기 슬라이딩 홈(5)에 소정간격을 두고 보상도선단자(11, 11')가 연속적으로 구비됨과 동시에 안내홈(9)이 형성된 가이드 레일(10)이 장착되며, 열전쌍(3)의 후면에 가이드 레일(10)을 따라 미끄럼 이동하는 미끄럼 돌기(13)가 장착되면서 미끄럼 돌기(13)를 사이에 두고 열전쌍(3)의 후면에 보상도전단자(11, 11')와 선택적으로 접촉하면서 대차(2)에 적재된 코일(1)의 온도를 출력하도록 제1, 2접점(12, 12')이 장착된 구조로 이루어져 있다.As shown in FIG. 1, the conventional apparatus for measuring the room temperature of the coil 1 in the conventional annealing furnace 14 includes a sliding groove 5 along the traveling direction of the coil 1 bogie 2 on the outer wall of the annealing furnace 14. It is formed concave, and the guide rail 10 is formed with a guide groove (9) is provided at the same time the compensation lead terminals (11, 11 ') are continuously provided at a predetermined interval in the sliding groove (5), the thermocouple ( 3) is equipped with a sliding projection (13) for sliding along the guide rail (10) at the rear of the rear surface of the thermocouple (3) with the sliding projection (13) between the optional conductive conductors (11, 11 ') and optional The first and second contact points 12 and 12 'are mounted to output the temperature of the coil 1 mounted on the trolley 2 while contacting with each other.
그러나, 상기 종래의 소둔로 내의 코일 실온 측정장치의 소둔로(14) 내벽체에 고정 형성되는 안내홈(9)은 소둔로(14) 내의 고열로 인해 열변형되는 문제점과, 상기 열전쌍(3)의 후단부에 구비된 미끄럼 돌기(13)가 안내홈(9)의 오목 라인딩부와 볼록 라인딩부를 연속적으로 통과할 때 보상도선(8, 8')과 제1, 2접점(12, 12')이 접촉하여 스파크를 발생됨으로써 접촉불량을 야기해 정확한 온도데이터 관리가 곤란한 문제점이 발생하며,However, the guide groove 9 fixed to the inner wall of the annealing furnace 14 of the conventional coil room temperature measuring apparatus in the annealing furnace has a problem of thermal deformation due to high heat in the annealing furnace 14, and the thermocouple 3. Compensation leads (8, 8 ') and the first and second contact (12, 12') when the sliding projection 13 provided at the rear end of the guide groove (9) passes through the concave and convex lines of the guide groove (9) continuously ) Generates sparks due to contact, which causes contact failure, making it difficult to accurately maintain temperature data.
또한, 상기 미끄럼 돌기(13)의 제1, 2접점(12, 12')이 상시 코일(1)이 안착된 대차(2) 측면에 돌출되어 있어 열변형이 발생되고, 상기와 같이 변형된 상태에서는 안내홈(9)을 따라 미끄럼 이동시 쉽게 파손되는 문제점이 발생하였다.In addition, the first and second contact points 12 and 12 ′ of the sliding protrusion 13 protrude to the side of the trolley 2 on which the coil 1 is always seated so that thermal deformation occurs, and the deformation state as described above. In the sliding groove along the guide groove (9) occurred a problem that is easily broken.
특히, 보상도선(8, 8')이 외부로 인출될 때 슬라이딩 홈(5)이 소둔로(14) 내, 외부를 관통시켜 형성함으로써, 소둔로(14) 내의 수소와 같은 분위기가스가 외부로 누기(7)되어 공기와 접촉하는 경우 폭발의 위험성이 항시 존재하는 문제점이 있다.In particular, when the compensation wires 8 and 8 'are drawn out, the sliding groove 5 is formed in the annealing furnace 14 to penetrate the outside, so that an atmosphere gas such as hydrogen in the annealing furnace 14 is brought out. There is a problem that the risk of explosion is always present when it comes in contact with air 7.
본 발명은 상기와 같은 문제점을 해결하기 위하여 도출된 것으로서, 소둔로에 공급되는 분위기가스를 냉각가스로 이용하는 전, 후진되는 수평타입의 중공관구조를 이용함으로써 열변형과 접촉불량을 방지하여 정확한 온도데이터 관리가 가능한 고온 소둔로 내의 대차 온도측정장치를 제공하는데 그 목적이 있다.The present invention is derived to solve the above problems, by using a horizontal hollow tube structure of the front and back, using the atmosphere gas supplied to the annealing furnace as the cooling gas to prevent heat deformation and contact failure to accurate temperature The purpose is to provide a bogie temperature measuring device in a high temperature annealing furnace capable of data management.
