본 발명에서 상기 회전몸체(110)는 턴디쉬 노즐(A)을 좌우방향으로 회전시켜 상기 측정센서(151)가 통기량을 원활하게 측정할 수 있도록 유도하는 역할을 수행한다.In the present invention, the rotating body 110 serves to guide the measurement sensor 151 to smoothly measure the amount of ventilation by rotating the tundish nozzle (A) in the left and right directions.

이때 상기 회전몸체(110)는 다양한 구성을 갖는 구동부재(111)를 이용하여 회전시킬 수 있으나, 본 발명에서는 상기 회전몸체(110)와 연결되는 감속기(미 도시됨)와 상기 감속기를 구동시키기 위한 모터(미 도시됨)로 구성하여 상기 회전몸체(110)를 일정속도로 회전시켰다.In this case, the rotating body 110 may be rotated using the driving member 111 having various configurations, but in the present invention, a speed reducer (not shown) connected to the rotating body 110 may be used to drive the speed reducer. The rotating body 110 was rotated at a constant speed by configuring a motor (not shown).

한편, 상기 고정부재(120)는 회전하는 턴디쉬 노즐(A)을 견고하게 고정하기 위한 것으로 볼트 또는 클램프 등과 같은 다양한 고정수단이 적용될 수 있으나, 본 발명에서는 고정작업의 용이성을 위해서 스톱퍼 실린더를 사용하였다.On the other hand, the fixing member 120 is for fixing the rotating tundish nozzle (A) firmly, but various fixing means such as bolts or clamps may be applied, but in the present invention, a stopper cylinder is used for ease of fixing operation. It was.

특히 상기 지지몸체(130)는 상부에 형성되는 수평레일(131)을 따라서 상기 이동몸체(140)가 턴디쉬 노즐(A)의 위치를 따라서 좌우방향으로 이동할 수 있도록 지지 및 유도하는 역할을 수행한다.In particular, the support body 130 serves to support and guide the movable body 140 to move left and right along the position of the tundish nozzle A along the horizontal rail 131 formed thereon. .

이때 상기 수평레일(131)은 이동몸체(140) 및 보조몸체(150)의 하중에 대한 지지력을 갖으며 정밀한 미끄럼운동을 유도할 수 있는 LM(Linear Motion)가이드를 사용하였으며, 상기 이동몸체(140)의 일측에는 LM블록을 설치하였다.At this time, the horizontal rail 131 has a support force for the load of the moving body 140 and the auxiliary body 150, and used a linear motion (LM) guide that can induce a precise sliding movement, the moving body 140 On one side of)) LM block was installed.

또한, 상기 제1모터(133)는 제1나선축(132)을 정회전 또는 역회전시켜 턴디쉬 노즐(A)의 위치에 따라서 나선결합된 상기 이동몸체(140)를 좌우방향으로 이동시킬 수 있다.In addition, the first motor 133 may rotate the first spiral shaft 132 forward or reverse rotation to move the spirally coupled moving body 140 in the left and right directions according to the position of the tundish nozzle (A). have.

아울러 상기 수평레일(131)을 따라서 좌우방향으로 이동할 수 있도록 형성하되 하부에는 뚜껑(161)을 설치하여 상하방향으로 이동시켜 턴디쉬 노즐(A)의 상단을 밀폐시켜 압축공기를 내부로 공급하기 위한 공급공(161a)이 일측에 구비되는 승하강부재(160)가 더 포함할 수 있는데, 이는 턴디쉬 노즐(A)의 구조상 외부에서 공급되는 기체는 다시 외부로 배출되지 않고 내부로만 취입되므로 이러한 상태를 확인하기 위해서 턴디쉬 노즐(A)의 상단을 밀폐시켜 상기 공급공(161a)을 통해서 외부의 압축공기를 내부로 공급하여 턴디쉬 노즐(A)의 외부로 배출되는 압축공기를 측정하여 기밀성의 여부를 확인하기 위함이다.In addition, the horizontal rail 131 is formed so as to move in the left and right directions, but the cap 161 is installed at the bottom to move upward and downward to seal the top of the tundish nozzle A so as to supply compressed air to the inside. The elevating member 160 may further include a supply hole 161a provided at one side thereof, which is because the gas supplied from the outside is blown into the inside only instead of being discharged to the outside again due to the structure of the tundish nozzle A. In order to confirm that the top of the tundish nozzle (A) is sealed and supplied with compressed air from the outside through the supply hole (161a) to measure the compressed air discharged to the outside of the tundish nozzle (A) To check whether or not.

이때 상기 뚜껑(161)의 하부에는 턴디쉬 노즐(A)의 상단과 맞닿아 기밀성을 확보할 수 있도록 패킹이 형성되고, 상기 공급공(161a)에는 압축공기의 공급량 및 압력을 조절 및 측정할 수 있는 압력센서가 연결될 수 있다.In this case, a packing is formed at the lower portion of the lid 161 so as to contact the upper end of the tundish nozzle A to secure airtightness, and the supply hole 161a may adjust and measure the supply amount and pressure of the compressed air. Pressure sensors can be connected.

따라서 상기 공급공(161a)을 통해서 일정한 압력을 갖는 압축공기가 공급된 상태에서 압력의 변화가 없으면 기밀성이 유지됨을 확인할 수 있고, 반대로 압력의 변화가 발생하게 되면 턴디쉬 노즐(A)의 표면에 손상이 발생했다는 것을 파악할 수 있는 것이다.Therefore, it can be confirmed that airtightness is maintained when there is no change in pressure in the state where compressed air having a constant pressure is supplied through the supply hole 161a, and on the contrary, when a change in pressure occurs, a surface of the tundish nozzle A is formed. You can see that damage has occurred.

또한, 상기 승하강부재(160)는 실린더를 사용하여 상기 뚜껑(161)이 턴디쉬 노즐(A)의 상단에 맞닿을 수 있도록 이동시킨다.In addition, the elevating member 160 is moved so that the lid 161 abuts the upper end of the tundish nozzle (A) by using a cylinder.

특히 상기 이동몸체(140)는 일측에 수직방향으로 형성되는 수직레일(141)을 따라서 상기 보조몸체(150)를 원활하게 상하방향으로 이동할 수 있도록 지지 및 유도하는 역할을 수행한다.In particular, the movable body 140 supports and guides the auxiliary body 150 to be smoothly moved up and down along the vertical rail 141 formed in one direction in the vertical direction.

이때 상기 수직레일(141)은 보조몸체(150)의 하중에 대한 지지력을 갖으며 정밀한 미끄럼운동을 유도할 수 있도록 LM가이드를 사용하였으며, 상기 보조몸체(150)의 일측에는 LM블록을 설치하였다.At this time, the vertical rail 141 has a supporting force for the load of the auxiliary body 150, and used the LM guide to induce a precise sliding movement, one side of the auxiliary body 150 was installed an LM block.

또한, 상기 제2모터(143)는 제2나선축(142)을 정회전 또는 역회전시켜 턴디쉬 노즐(A)의 높이에 따라서 나선결합된 상기 보조몸체(150)와 측정센서(151)를 상하방향으로 이동시킬 수 있다.In addition, the second motor 143 rotates the second spiral shaft 142 forward or reverse to rotate the auxiliary body 150 and the measurement sensor 151 which are spirally coupled according to the height of the tundish nozzle A. FIG. It can be moved up and down.

특히 상기 측정센서(151)는 유입공(B)을 통해서 외부에서 턴디쉬 노즐(A)의 내부로 공급되는 압축공기의 통기량을 측정하기 위해서 풍속센서 또는 유속센서를 사용함이 바람직하다.In particular, the measurement sensor 151 preferably uses a wind speed sensor or a flow rate sensor in order to measure the air flow of the compressed air supplied to the inside of the tundish nozzle (A) from the outside through the inlet (B).

이때 유입공(B)에는 압축공기의 공급량 및 압력을 조절 및 측정할 수 있는 압력센서가 더 연결되어 상기 측정센서(151)를 통해서 측정된 통기량과 비교하여 턴디쉬 노즐(A)의 불량상태를 확인할 수 있다.At this time, the inlet hole (B) is further connected to a pressure sensor for adjusting and measuring the supply amount and pressure of the compressed air, compared to the aeration amount measured through the measuring sensor 151, the bad state of the tundish nozzle (A) You can check.

아울러 상기 측정센서(151)의 일측에는 근접센서(미 도시됨)를 더 형성하여 상기 제1모터(133) 및 제2모터(143)를 자동으로 작동시켜 상기 측정센서(151)가 턴디쉬 노즐(A)의 내경에 항상 근접되도록 이동시킬 수 있다.In addition, one side of the measurement sensor 151 further forms a proximity sensor (not shown) to automatically operate the first motor 133 and the second motor 143 so that the measurement sensor 151 is a tundish nozzle. It can be moved so that it always approaches the inner diameter of (A).

따라서 본 발명은 턴디쉬 노즐(A)의 내경에 대한 전체적인 통기량을 측정하여 불량부위를 사전에 파악함으로써 용강 품질을 향상시킴은 물론 측정작업의 신뢰성을 확보할 수 있다.Therefore, the present invention can improve the quality of the molten steel as well as to ensure the reliability of the measurement work by measuring the total amount of air flow to the inner diameter of the tundish nozzle (A) in advance to determine the defective portion.
