이와 같이 구성된 본 발명의 작동상태를 상세히 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described in detail as follows.

먼저, 고로(1)에 형성된 복수개의 출선구(1a)를 통하여 출선되는 용선의 온도를 측정하는 온도 측정장치는 용선의 온도를 측정하지 않을 경우에는 한 쌍의 출선구(1a) 중앙에 위치되어 대기 상태가 유지된다. 즉, 회동레일(16)은 고정레일(15)의 중앙부분에 위치되고 상기 회동레일(16)의 저면에 설치된 이동대차(4)는 후진된 상태를 유지하게 되는 것이다.First, the temperature measuring device for measuring the temperature of the molten iron drawn out through the plurality of outlets 1a formed in the blast furnace 1 is located in the center of the pair of outlets 1a when the temperature of the molten iron is not measured. The standby state is maintained. That is, the rotation rail 16 is located in the center of the fixed rail 15 and the moving trolley 4 installed on the bottom of the rotation rail 16 is to maintain the reversed state.

이러한 상태에서 복수개의 출선구(1a)중 어느 일측이 개방되어 용선을 출선할 때에는 용선이 출선되는 출선구(1a) 측으로 회동레일(16)이 이동되도록 회동모터(13)를 작동시키는 것이며, 상기 회동모터(13)가 작동되면 그 회동모터(13)의 회전력은 작동바(14)를 작동시키게 되므로 상기 작동바(14)에 연결된 회동레일(16)은 중심축(12)을 기점으로 회동되는 것이며, 이때 고정레일(15)은 회동레일(16)이 원활하게 회동될 수 있도록 안내하게 되는 것이다.In this state, when one side of the plurality of outlets 1a is opened and the boat is drawn out, the rotation motor 13 is operated so that the rotation rail 16 moves to the outlet port 1a where the charter is drawn out. When the rotational motor 13 is operated, the rotational force of the rotational motor 13 operates the operation bar 14, so that the rotation rail 16 connected to the operation bar 14 is rotated around the central axis 12. In this case, the fixed rail 15 is to guide the rotating rail 16 to be rotated smoothly.

상기와 같이 회동레일(16)이 회동된 후 고정레일(15)의 저면에 설치된 구동모터(3)가 작동되면 그 구동모터(3)의 회전력은 이동대차(4)로 전달되어 상기 이동대차(4)를 출선구(1a)측으로 이동시키게 되는 것이다.After the rotating rail 16 is rotated as described above, when the driving motor 3 installed on the bottom of the fixed rail 15 is operated, the rotational force of the driving motor 3 is transmitted to the moving trolley 4 and the moving trolley ( 4) will be moved to the outlet (1a) side.

그리고 상기 이동대차(4)가 이동되면 그 이동대차(4)에 설치된 측정수단은 출선구(1a)를 통하여 출선되는 용선의 근접되므로 비접촉식으로 용선을 측정하는 측정수단의 측정렌스(6) 및 광 화이버(7)에 의해서 용선의 온도가 측정되는 것이다.When the moving trolley 4 is moved, the measuring means installed in the moving trolley 4 is close to the molten iron drawn out through the tap opening 1a, so that the measuring lance 6 and the light of the measuring means measuring the molten iron in a non-contact manner. The temperature of the molten iron is measured by the fiber 7.

이와 같이 용선의 온도 측정이 완료되면 상기 측정수단은 구동모터(3) 및 회동모터(13)의 구동에 의해서 대기상태로 복원되는 것이며, 이때에는 상기 회동레일(16)이 리미트 스위치(17)를 작동시키면 회동모터(13)가 정지되는 것이다.When the temperature measurement of the molten iron is completed as described above, the measuring means is restored to the standby state by the driving of the driving motor 3 and the rotating motor 13, and in this case, the rotating rail 16 opens the limit switch 17. When activated, the rotating motor 13 is stopped.

한편, 고로(1)에 형성된 출선구(1a)중 또 다른 출선구(1a)를 통하여 용선이 출선될 때에는 상술한 바와 같은 과정을 통하여 용선이 출선되는 출선구(1a) 측으로 온도 측정장치를 이동시켜 용선의 온도를 측정하게 되는 것이다.On the other hand, when the molten iron is discharged through another tapping opening 1a among the tapping openings 1a formed in the blast furnace 1, the temperature measuring device is moved to the taping opening 1a side where the molten iron is drawn through the above-described process. It is to measure the temperature of the molten iron.

이와 같이 본 발명은 한 개의 온도 측정장치를 이용하여 한 쌍의 출선구를 통하여 출선되는 용선의 온도를 측정할 수 있게 되므로 온도 측정장치의 설치 및 유지보수에 따르는 비용을 절감할 수 있게되는 특유의 효과가 있다.As described above, the present invention can measure the temperature of the molten iron drawn out through a pair of outlets using a single temperature measuring device, thereby reducing the cost of installing and maintaining the temperature measuring device. It works.

또한 본 발명은 고로 주변에 설치되는 설비가 축소되므로 공간을 효율적으로 이용할 수 있게되는 특유의 효과가 있다.In addition, the present invention has the peculiar effect of being able to use the space efficiently because the equipment installed around the blast furnace is reduced.
