본 고안의 열연직송압연에 따라 연속주조-열간압연간의 주편온도의 적정관리를 위해 연속주조-연간압연공정내에서 고온주편의 표면온도 측정장치에 관한 것으로서, 보다 상세히는 연속주조의 2차 냉각대와 연속주조-열연간의이 이송테이블에 설치하여 사용하는 경우, 측정온도치를 연속주조공정의 2차 냉각제어에 피드백시켜 주편의 온도관리를 행할수 있고, 열연가열로 장입측에 설치하여 사용하는 경우, 주편의 장입온도를 측정하므로서 열연가열로연소제어의 입력데이타로 이용할수 있게되는 연전대접촉식 고온주편의 표면온도 측정장치에 관한것이다.The present invention relates to an apparatus for measuring the surface temperature of hot castings in a continuous casting-rolling process for proper management of the casting temperature between the continuous casting and the hot rolling according to the hot rolling direct rolling of the present invention. When continuous casting-hot rolling is used on the transfer table, the temperature of the cast can be managed by feeding back the measured temperature value to the secondary cooling control of the continuous casting process. The present invention relates to a surface temperature measuring device for a thermocouple contact type hot cast which can be used as an input data for combustion control by hot-rolled heating by measuring the charging temperature of the cast.

이러한 기술과 관련된 종래의 장치로는, 연속주조공정에서 주편의 표면온도를 측정함에 있어서 열전대 접점 부분을 내장하는 철편이 롤식 압접기에 의해 회전하면서 주폄에 접촉, 함몰되어 주편의 이동과 함께 주편에 열전대가 함몰된 부위의 온도를 연속적으로 측정하는 것이 있었다.In the conventional apparatus related to this technique, in measuring the surface temperature of the cast steel in the continuous casting process, the iron piece containing the thermocouple contact portion is rotated by the roll-type welding machine, and contact with the cast iron while being depressed to move the cast steel thermocouple to the cast steel. There was a continuous measurement of the temperature of the recessed site.

그러나, 상기와 같은 종래의 기술에 있어는 열전대를 주편표면에 함몰시켜 온도를 측정하는 경우 열전대의 주편표면접촉과 분리가 용이치 않으므로 열전대의 반복사용이 곤란하고 주편손상의 문제가 대두되는 것이었다.However, in the conventional technique as described above, when the thermocouple is recessed to the surface of the slab, the temperature is measured, and thus the thermocouple slab surface contact and separation are not easy, so the repeated use of the thermocouple is difficult and the problem of slab damage arises.

또, 열간압연공정에서는 방사온도계가 사용되나, 열간압연 가열로 장입측에 설치하여 사용하는 경우 주편표층부에 스케일이 부착되어 온도측정정도를 크게 하락시키므로 표면온도를 정도 높게 측정하기 위해서는 열전대의 접촉과 분리한 용이한 표면온도측정장치가 필요한 것이었다.In addition, in the hot rolling process, a radiation thermometer is used.However, when installed on the charging side of the hot rolling furnace, the scale is attached to the surface of the cast steel layer, which greatly reduces the temperature measurement accuracy. An easy surface temperature measurement device was required.

본 고안의 목적은 열연직송압연에 따라 연속주조-연간압연간의 주편온도의 적정관리가 가능함은 물론, 연주-열간공정내에서 정도가 높고 용이하게 고온주편의 표면온도를 측정할 수 있는 열전대접촉식 고온주편의 표면온도 측정장치를 제공하려는 것이다.The purpose of the present invention is the thermocouple contact type which can measure the surface temperature of high temperature cast easily and easily in the casting-hot process. An object of the present invention is to provide a surface temperature measuring device for a hot cast.

이하에서 본 고안을 첨부된 도면에 따라 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안의 장치를 개략적으로 도시한 구성도이다.1 is a schematic view showing a device of the present invention.

여기서는, 좌우측의 지지대(5)에 의해 롤러테이블(8)이 회전가능하게 지지되고, 지지대(5)의 상부로 직립되게 연설된 베어링부(4)가 마련되어있다.Here, the bearing table 4 is rotatably supported by the left and right supporters 5 so as to stand upright on the support 5.

또, 상기 베어링부(4)는 회전원판(1)를 보유하는 회전원판축(3)이 회전 가능하게 설치되고, 이 회전원판(1)은 주편(6)위에서 밀착되게 설치된다.In addition, the bearing portion 4 is provided with a rotatable disc shaft 3 having a rotatable disc 1 rotatably, and the rotatable disc 1 is installed in close contact on the cast piece 6.

상기 회전원판(1)은 제2도와 같이 중심방향으로 열전대(2)의 삽입공정을 위한 요홈(11)을 갖고, 이 요홈(11)부위의 외주면에는 접점판 접착부(12)기 요설되어 두 개로 분리구성되고, 이 분할된 회전원판(1)의 고정결합을 위한 복수의 관통홀(13)이 천설되어 진다.The rotating disc 1 has a groove 11 for inserting the thermocouple 2 in the center direction as shown in FIG. 2, and the contact plate adhesive portion 12 is formed on the outer circumferential surface of the groove 11 at two points. Separately constructed, a plurality of through-holes 13 for the fixed coupling of the divided rotary disk 1 is laid.

또, 상기 회전원판(1)의 요홈(11)에 접점판(21)이 접점된 열전대(2)가 끼워져 열전대(2)의 접점판(21)이 회전원판(1)의 접점판 접착부(12)에 밀칙되게 부착고정된다.In addition, the thermocouple 2 in which the contact plate 21 is contacted is inserted into the recess 11 of the rotating disc 1 so that the contact plate 21 of the thermocouple 2 is attached to the contact plate 12 of the rotating disc 1. Is fixed tightly to the

또, 열전대(2)의 리이드선은 회전원판축(3)의 동공을 따라 일측베어링부(4)에서 회전원판축(3)의 단부에 설치된 슬립링(7)으로 연결되고 이 슬립링(7)의 출력단자가 기록계와 연결되어 진다.Further, the lead wire of the thermocouple 2 is connected to the slip ring 7 provided at the end of the rotating disc shaft 3 from one side bearing portion 4 along the pupil of the rotating disc shaft 3, and the slip ring 7 ) Is connected to the recorder.

상기 베어링부(4)는 제3도와 같이 회전원판축(3)을 회전가능하게 지지하는 슬라이더(42)가 가이드(41)내에서 상하로 승강되고, 이 슬라이더(42)의 하단에는 스프링(43)이 탄설된다.In the bearing part 4, as shown in FIG. 3, a slider 42 rotatably supporting the rotation disc shaft 3 is lifted up and down in the guide 41, and a spring 43 is provided at the lower end of the slider 42. ) Is coaled.

이와같이 구성된 본 고안은 제1도 및 제3도에서와 같이 롤러테이블(8)에 의해 주편(6)이 이동하는 과정에서 주편(6)의 높이보다 낮게 위치한 회전원판(1)에 의해 주편(6)의 윗면과 열전대(2)의 접점부위인 접점판(21)이 밀착접촉되므로서 열전대(2)의 리이드선과 연결된 기록계를 통하여 주편(6)의 온도를 측정할 수 있다.The present invention configured as described above has the cast plate 6 by the rotating disc 1 positioned lower than the height of the cast plate 6 in the course of moving the cast plate 6 by the roller table 8 as shown in FIGS. Since the contact surface 21 of the upper surface of the thermocouple 2 and the contact portion 21 of the thermocouple 2 are in close contact with each other, the temperature of the slab 6 can be measured through a recorder connected to the lead wire of the thermocouple 2.

또, 회전원판(1)에 설치된 연결대(2)의 리이드선은 회전원판축(3)의 동공을 따라 슬립링(7)에 연결되므로서, 회전원판(1)의 회전운동에 따른 연전대(2)의 라이드선은 꼬임이 방지된다.In addition, the lead wire of the connecting table (2) provided on the rotating disk (1) is connected to the slip ring (7) along the pupil of the rotating disk shaft (3), so that the connecting rod according to the rotational movement of the rotating disk (1) ( The ride line of 2) is prevented from twisting.

또, 주편(6)의 이송에 따라 회전원판(1)이 공회전하므로서 열전대(2)의 분리가 용이한 것이다.In addition, since the rotating disc 1 is idling in accordance with the transfer of the slab 6, the thermocouple 2 is easily separated.

또, 연속주조-열간압연공정의 주편온도는 1200-500℃정도를 크로멜알루멜(chromel-Alumel) 열전대를 사용하며, 열전대(2)의 접점부분인 접점판(21)은 내구성과 열전도특성을 고려하여 0.5mm이하의 두께를 갖는 스텐레스판으로 선택한 것이다.In addition, the casting temperature of the continuous casting-hot rolling process uses a chromel-Alumel thermocouple of about 1200-500 ° C. The contact plate 21, which is the contact portion of the thermocouple 2, exhibits durability and thermal conductivity characteristics. In consideration of the stainless steel plate having a thickness of less than 0.5mm.

제4도는 본 고안에 의한 온도측정그라프를 나타낸 것이다.4 shows a temperature measurement graph according to the present invention.

여기서는, 회전원판(1)의 열전대(2)에 의한 온도는 감지는 회전워판(1)의 열전대(2) 부착부분이 고온주편(6)에 접촉할때 온도가 급격히 상승하고 회전원판(1) 내부에의 열전도로 온도상승구배가 둔화되다가 주편(6)의 표면온도에 도달하게 된다.Here, the temperature by the thermocouple 2 of the rotating disc 1 is detected when the temperature of the thermocouple 2 attachment portion of the rotating warp plate 1 is in contact with the high temperature slab 6 and the temperature of the rotating disc 1 is increased. The gradient of temperature rise is slowed down by the heat conduction inside, and the surface temperature of the slab 6 is reached.

이때, 열전대(2)에 의한 온도응답시간을 고려하여 회전원판(1)의 열전대(2)와 고온주편(6)의 접촉시간은 최고 5초로 하는 것이 바람직하다.At this time, in consideration of the temperature response time by the thermocouple 2, it is preferable that the contact time between the thermocouple 2 and the high temperature slab 6 of the rotating disc 1 is at most 5 seconds.

상술한 바와같이 본 고안에 의하면, 주편의 표면온도 측정은 ±10℃이내의 높은 정도를 가지며, 열간압연가열로 장입측에 설치하여 열간압연주편의 장입 온도를 정도 높게 검출하므로써 열간압연 가열로의 연소제어를 효율적으로 할수 있고, 열전대(2)를 보유하는 회전원판을 마련하여 열전대의 접촉가 분리가 용이하므로써 검출 시간이 단축되는 등의 실용상 유익한 특장점이 있는 것이다.As described above, according to the present invention, the surface temperature measurement of the cast steel has a high degree within ± 10 ° C, and is installed on the charging side of the hot rolling furnace to detect the charging temperature of the hot rolled cast steel to a high degree. The combustion control can be efficiently performed, and a rotating disc holding the thermocouple 2 is provided, so that the contact of the thermocouple can be easily separated, so that the detection time can be shortened.
