본 고안은 스라브 가열온도 측정장치에 관한 것으로, 특히 가열로내의 스라브를 추출하는 익스트랙터 상면에 열전대(Thermo couple)를 설치하여 스라브의 가열온도를 정확하게 측정할 수 있도록 한 것이다.The present invention relates to a slab heating temperature measuring apparatus, in particular, by installing a thermocouple on the upper surface of the extractor for extracting the slab in the heating furnace to accurately measure the heating temperature of the slab.

일반적으로 스라브의 가열온도를 측정하기 위해서는 로내이 스라브가 방출하는 빛을 파이로메터(pyrometor)에 의해 측정하는 방법과 수식모델에 의해 추정계산하는 방법이 사용되고 있다.In general, in order to measure the heating temperature of the slab, a method of measuring the light emitted by the furnace slab by a pyrometor and a method of estimating it by a mathematical model are used.

그러나 전자의 경우에는 가열로의 추출단과 파이로메터를 설치하여 스라브의 온도를 측정하게 되는데, 이때 파이로메터는 수시로 변동되는 로내 분위기 온도의 영향을 크게 받음은 물론, 파이로메터의 수광지점에 스라브의 스케일이 누적될 경우 정확한 온도측정을 할 수 없으며, 이동하는 스라브와 수광위치가 정확히 일치하지 않는 경우에도 측정온도의 신뢰도가 낮아지게 되는 문제점이 지적된다.However, in the former case, the temperature of the slab is measured by installing the extraction stage of the furnace and the pyrometer. At this time, the pyrometer is not only affected by the fluctuating atmosphere temperature, but also at the light receiving point of the pyrometer. Accumulated temperature measurement is not possible when the scale of the slab is accumulated, and even if the moving slab and the light receiving position are not exactly matched, the problem that the reliability of the measured temperature is pointed out is pointed out.

또한, 후자의 경우 즉, 수식모델에 의한 측정방법의 경우에는 스라브 측온시험을 통해 계산식에 필요한 계수를 도출하여 스라브온도 계산시에 적용하게 되는데, 실제작업조건이 스라브온도 시험시와 동일한 경우 정확한 스라브 가열온도를 계산할 수 있지만 현실적으로 작업조건은 수시로 변화하므로 모델계산온도 역시 정확한 스라브 가열온도라고 신뢰할 수 없다는 문제점이 지적된다.In addition, in the latter case, that is, in the case of the measurement method based on a mathematical model, a coefficient necessary for a calculation formula is derived through a slab temperature test and applied when calculating the slab temperature. It is pointed out that the heating temperature can be calculated, but the working conditions change from time to time, so the model calculation temperature cannot be trusted to be accurate slab heating temperature.

본 고안은 상기한 문제점들을 감안하여 가열 후 추출되는 스라브온도를 정확히 측정함과 동시에, 스라브온도를 측정하기 위한 별도의 장치, 설치공간을 삭제할 수 있게 된 스라브 가열온도 측정장치를 제공함에 그 목적이 있는바, 이하에서 본 고안의 양호한 실시예를 첨부도면에 의해 상세히 설명한다.The present invention is to provide a slab heating temperature measuring device capable of precisely measuring the slab temperature extracted after heating in consideration of the above-mentioned problems, and at the same time, a separate device for measuring the slab temperature, and the installation space can be deleted. In the following, a preferred embodiment of the present invention will be described in detail by the accompanying drawings.

제1도는 가열로(1)에서 가열된 스라브(S)를 롤러테이블(2)로 추출하는 익스트랙터(3)를 나타낸 것으로, 본 고안에서는 상기 익스트랙터(3)의 상면에 측정장치(M)를 매립설치 하였다.FIG. 1 shows an extractor 3 for extracting the slab S heated in the heating furnace 1 to the roller table 2. In the present invention, the measuring device M is disposed on the upper surface of the extractor 3. Landfill was installed.

제2도는 본 고안 측정장치(M)를 분해도시한 것으로, 익스트랙터(3)를 구성하는 아암(3a)에 수직으로 관통형성시킨 수납부(4)와, 상기 수납부(4)의 상부에 삽입설치되며 그 하단에 완충기구(5)를 구비하여 스라브(S)의 적재시에 소정구간 하향이동하는 홀더(6)와 상기 홀더(6)내부에 상향 돌출되도록 삽입설치되어 스라브(S)와 접촉하여 온도정보신호를 발생하는 열전대(7)로 구성된다.2 is an exploded view of the measuring device M of the present invention, and includes an accommodating portion 4 vertically penetrating the arm 3a constituting the extractor 3 and an upper portion of the accommodating portion 4. Inserted and provided with a shock absorbing mechanism (5) at the lower end is inserted into the holder (6) and downwardly protrudes inside the holder (6) to move down a predetermined section when loading the slab (S) and the slab (S) and And a thermocouple 7 which contacts and generates a temperature information signal.

상기 수납부(4)는 아암(3a)의 상부에 형성되며 그 양측에 안내홈(41)을 대향형성시킨 수납실(42)과, 상기 수납실(42)의 하부에는 걸림턱(43)으로 구획된 배출구멍(44)으로 이루어 진다.The accommodating portion 4 is formed at an upper portion of the arm 3a and includes a accommodating chamber 42 having opposing grooves 41 formed on both sides thereof, and a locking jaw 43 at the lower portion of the accommodating chamber 42. Comprised of a discharge hole 44 is partitioned.

상기 홀더(6)는 본체(61)의 양측에 안내돌출부(62)가 형성되어 상기 안내홈(41)에 승강가능하게 대응 결합되며, 본체(61)의 하면양측에 구비되는 완충기구(5)는 복수개의 탄성부재(51)와 지지판(52)으로 구성되어 상기 걸림턱(43)의 상면에 안착 고정 설치된다.The holder 6 has guide protrusions 62 formed on both sides of the main body 61 so as to be lifted and coupled to the guide groove 41 so that the holder 6 is provided at both sides of the lower surface of the main body 61. Is composed of a plurality of elastic members 51 and the support plate 52 is installed seated fixed on the upper surface of the locking jaw (43).

또한 본체(61)의 중앙에는 안내구멍(63)이 형성되고, 안내구멍(63)의 양측에는 소정깊이의 고정홈(64)이 형성되어 열전재(7) 양측의 고정축(71)이 삽입고정되며, 열전대(7)는 그 하단에 리드선(72)이 인출되어 도시되지 않은 온도측정계기에 전기 회로적으로 연결된다.In addition, a guide hole 63 is formed in the center of the main body 61, and fixing grooves 64 of a predetermined depth are formed on both sides of the guide hole 63, so that the fixed shafts 71 on both sides of the thermoelectric material 7 are inserted. The thermocouple 7 is fixed, and the lead wire 72 is drawn out at the lower end thereof and is electrically connected to a temperature measuring instrument (not shown).

도면 중 미설명 부호(42a)와 (63a)는 스케일의 낙하안내를 위한 공간부이다.In the drawings, reference numerals 42a and 63a denote space portions for falling guidance of the scale.

이와 같은 구성의 본 고안 측정장치(M)는 스라브(S)의 적재 대기시에 제3도(가)에서와 같이, 완충기구(5)를 구성하는 탄성부재(51)에 된다.The measuring device M of the present invention having such a configuration is the elastic member 51 constituting the shock absorbing mechanism 5 as shown in FIG.

이러한 대기상태에서 제3도 (b)에서와 같이 스라브(S)가 아암(3a)의 상면에 적재되면 열전대(7)는 스라브(S)의 하중에 의해 압력을 부여받게 되며, 이 압력은 홀더(6)를 통해 완충기구(5)에 가해지게 되므로 탄성부재(51)를 압축시키면서 홀더(6)는 그 양측의 안내돌출부(62)가 수납실(42) 양측의 안내홈(41)을 따라 수직하강 이동하게 된다.In this standby state, when the slab S is loaded on the upper surface of the arm 3a as shown in FIG. 3 (b), the thermocouple 7 is pressurized by the load of the slab S, and the pressure is applied to the holder. Since it is applied to the shock absorbing mechanism (5) through the (6), while the compressing the elastic member 51, the holder 6 has guide protrusions 62 on both sides thereof along the guide grooves 41 on both sides of the storage chamber (42). It moves down vertically.

이러한 상태에서 열전대(7)는 탄성부재(51)의 복귀력에 의해 스라브(S)와 접촉상태를 유지하게 되며, 따라서 스라브(S)의 온도정보는 리드선(72)을 통해 온도측정계기에 전달되므로, 이 정보에 의해 가열로의 연소를 제어하게 된다.In this state, the thermocouple 7 maintains contact with the slab S by the return force of the elastic member 51, so that the temperature information of the slab S is transmitted to the temperature measuring instrument through the lead wire 72. Therefore, the combustion of the heating furnace is controlled by this information.

한편, 스라브(S)의 온도측정시에 스라브(S)로부터 분리되는 대부분의 스케일은 제3도 및 제4도에서와 같이 홀더(6)와 수납실(42)상이의 공간부(42a)를 통해 배출구멍(44)의 하부로 낙하 제거되며, 열전대(7) 상부에서 떨어지는 일부 스케일은 안내구멍(63)과 열전대(7) 사이의 공간부(63a)를 통해 배출구멍(44) 하부로 낙하 제거되므로 수케일에 의한 온도측정 방해요인은 효과적으로 제거된다.On the other hand, most of the scales separated from the slab S at the time of measuring the temperature of the slab S, as shown in FIG. 3 and FIG. 4, have the space 42a between the holder 6 and the storage chamber 42. Some scales falling from the upper portion of the discharge hole 44 through the space portion 63a between the guide hole 63 and the thermocouple 7 fall to the lower portion of the discharge hole 44. As it is eliminated, the disturbance of temperature measurement due to the scale is effectively eliminated.

이와같은 본 고안 측정장치(M)는 가열 후 추출되는 스라브(S)의 온도를 정확하게 측정하여 측정온도 신뢰도를 향상시킴과 동시에 별도의 측정 방해요인은 효과적으로 제거된다.The present invention measuring device (M) accurately measures the temperature of the slab (S) extracted after heating to improve the measurement temperature reliability and at the same time eliminates the separate measurement disturbances effectively.

이와 같은 본 고안 측정장치(M)는 가열 후 추출되는 스라브(S)의 온도를 정확하게 측정하여 측정온도 신뢰도를 향상시킴과 동시에 별도의 장치와 설치공간이 요구되지 않으므로 경비투자의 최소화와 공간효율의 극대화를 구현할 수 있게 된 유용한 고안이다.The measurement device (M) of the present invention accurately measures the temperature of the slab (S) extracted after heating to improve the reliability of the measurement temperature and at the same time does not require a separate device and installation space, minimizing the cost investment and space efficiency It's a useful design that allows for maximization.
