Description

열손실 방지를 위한 턴디쉬 가열장치{Heating apparatus of tundish for anti heat leak}Heated apparatus for preventing heat loss {Heating apparatus of tundish for anti heat leak}

본 발명은 턴디쉬 가열장치에 관한 것으로서, 특히 제강공장에서 래들내의 용강을 주입하는 용기인 턴디쉬(Tundish)의 커버 상부에 복수개의 축열식버너부를설치하여 턴디쉬 내부로 고온의 연소가스를 통과시켜서 턴디쉬를 균일하게 가열함과 동시에 배기가스가 가진 현열을 연소용 공기에 전달하여 열손실을 방지할 수 있도록 한 열손실 방지를 위한 턴디쉬 가열장치에 관한 것이다.The present invention relates to a tundish heating apparatus, and in particular, a plurality of regenerative burners are installed on the top of a cover of a tundish, which is a container for injecting molten steel in a ladle in a steelmaking factory, to allow high temperature combustion gas to pass through the tundish. The present invention relates to a tundish heating device for preventing heat loss by uniformly heating the tundish and transmitting sensible heat of the exhaust gas to combustion air to prevent heat loss.

일반적으로 도 1에 도시된 바와 같이, 턴디쉬(1)는 상온상태에서 내화물을 시공한 뒤 건조과정을 거쳐 턴디쉬 프리히터(preheater)를 이용하여 1200℃ 이상까지 승온시키며, 가열방법은 4개의 버너(3)를 턴디쉬 커버(2)의 길이 방향을 따라 다수개 형성된 구멍에 위치시킨 뒤 화염과 연소가스를 턴디쉬(1) 내부에 통과시켜 내화물을 가열시킨다.Generally, as shown in FIG. 1, the tundish 1 is heated to 1200 ° C. or more using a tundish preheater after drying the refractories at room temperature, followed by drying. The burner 3 is positioned in a plurality of holes formed along the longitudinal direction of the tundish cover 2 and then the flame and the combustion gas are passed through the tundish 1 to heat the refractory.

이때, 턴디쉬(1) 내부에서 연소된 연소가스는 별도의 폐열회수 장치를 거치지 않고 고온상태 그대로 턴디쉬 커버(2)와 턴디쉬(1) 사이의 틈새 및 턴디쉬 커버(2)와 버너(3) 사이의 틈새를 통해 외부로 방출되므로서 에너지 손실이 크게 발생되며, 특히 턴디쉬(1) 내부에는 용강중의 불순물 분리를 위해 내화물 재질의 댐(Dam)(6)이 설치되어 있어 연소가스와 내화물 간의 원활한 열전달을 방해하게 되어 결국 턴디쉬(1)의 길이 방향으로 온도 편차가 크게 나타나는 문제점이 있었다.At this time, the combustion gas burnt in the tundish (1) is a gap between the tundish cover (2) and the tundish (1) and the burnish cover (2) and the burner without going through a separate waste heat recovery device 3) Energy loss is largely generated as it is discharged to the outside through the gap between them. Especially, the refrigeration dam (6) is installed inside the tundish (1) to separate impurities from the molten steel. Interfering with the smooth heat transfer between the refractory, there was a problem that the temperature deviation in the longitudinal direction of the tundish (1) is large.

한편, 이러한 문제점을 해결하기 위해 턴디쉬(1)의 가열에 축열식 버너(미도시)를 적용할 경우, 이미 축열식 버너가 적용되어 있는 다른 설비와는 달리 턴디쉬(1)의 경우는 턴디쉬 커버(2)가 축열식 버너와 분리되어 있기 때문에 턴디쉬 커버(2)와 축열식 버너 사이에 완벽한 기밀을 유지 할 수가 없으므로 턴디쉬(1) 가열시 외부에서 차가운 공기가 턴디쉬(1) 내부로 침입하여 열손실이 발생되거나, 턴디쉬(1) 외부로 고온의 연소가스나 화염이 분출하여 축열식 버너(4)나 기타 외부 기기를 손상시키는 문제점이 있었다.On the other hand, in order to solve this problem when applying a regenerative burner (not shown) to the heating of the tundish (1), unlike the other equipment that is already applied to the regenerative burner, in the case of the tundish (1) tundish cover Since (2) is separated from the regenerative burner, it is not possible to maintain perfect airtight between the tundish cover (2) and the regenerative burner, so when the tundish (1) is heated, cold air enters the inside of the tundish (1). Heat loss or hot combustion gas or flame is blown out to the tundish 1 to damage the regenerative burner 4 or other external equipment.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 턴디쉬 커버에 설치되어 연소 및 배기가스의 열교환에 의해 턴디쉬의 열손실을 방지함과 동시에 턴디쉬 길이 방향의 온도편차를 줄이고, 연료절감을 도모할 수 있는 열손실 방지를 위한 턴디쉬 가열장치를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, is installed in the tundish cover to prevent the heat loss of the tundish by heat exchange of combustion and exhaust gas and at the same time reduce the temperature deviation in the tundish longitudinal direction It is an object of the present invention to provide a tundish heating device for preventing heat loss that can reduce fuel consumption.

상기와 같이 구성되는 본 실시예에 따른 열손실 방지를 위한 턴디쉬 가열장치의 작용을 설명하면 다음과 같다.Referring to the operation of the tundish heating apparatus for preventing heat loss according to the present embodiment configured as described above are as follows.

도 2 내지 도 4에 도시된 바와 같이, 축열식버너부(A~D)를 상기 턴디쉬 커버(2)의 구멍 상부에 적치시키고 축열식버너 본체(4)를 하부로 구동시키면 상기 방열판(8) 표면에 시공된 세라믹 파이버 재질의 내화물(12)이 턴디쉬 커버(2)의 표면에 닿아 기밀이 유지되면서 축열식버너 본체(4)가 턴디쉬 커버(2)의 구멍속으로 약 50 ∼100mm 정도 삽입되도록 한다.2 to 4, when the regenerative burner parts A to D are placed in the upper portion of the hole of the tundish cover 2 and the regenerative burner body 4 is driven downward, the surface of the heat sink 8 is exposed. The refractory burner body (12) made of ceramic fiber contacted the surface of the tundish cover (2) to maintain the airtight, so that the regenerative burner body (4) is inserted into the hole of the tundish cover (2) by about 50 to 100mm do.

이후, 상기 점화용 버너(13)를 이용하여 A 및 C측 축열식버너 본체(4)를 착화시킨 후, 연소 모드에 있는 축열식버너 본체(4)에서 연료가 버너 노즐(미도시)을 통해 분사되고, 연소공기는 턴디쉬(1) 내부를 통과하여 턴디쉬(1)를 가열시키며, 배기 모드에 있는 다른(B 및 D측) 축열식버너 본체(4)를 통해 축열체(5)를 가열시킨 다음 배기가스 자체는 약 300℃ 이하로 냉각된 후 절환밸브(7)를 거쳐배기팬(10)을 통해 대기중으로 배출되며, 이때 상기 절환밸브(7)의 V1, V3는 오픈(open)된 상태이고, V2, V4는 클로즈(close)된 상태이다.Thereafter, the A and C side regenerative burner bodies 4 are ignited using the ignition burner 13, and then fuel is injected through the burner nozzles (not shown) from the regenerative burner bodies 4 in the combustion mode. The combustion air passes through the interior of the tundish 1 to heat the tundish 1 and heats the heat accumulator 5 through the other (B and D side) regenerative burner body 4 in the exhaust mode. The exhaust gas itself is cooled to about 300 ° C. or less, and then discharged into the atmosphere through the exhaust fan 10 through the switching valve 7, where V1 and V3 of the switching valve 7 are open. , V2 and V4 are closed.

이러한 과정을 통해 고온의 배기가스가 보유한 현열(顯熱)을 상기 축열체(5)를 통해 연소공기에 전달하여 턴디쉬(1)의 가열에 이용함으로써, 종래의 턴디쉬 가열방법에 의할 경우 발생되었던 배기가스를 통한 손실 열량을 대폭적으로 줄일 수 있으며, 연료사용량 또한 절감이 가능하다.Through this process, the sensible heat of the high-temperature exhaust gas is transferred to the combustion air through the heat storage body 5 to be used for heating the tundish 1, and according to the conventional tundish heating method. The amount of heat lost through exhaust gas can be greatly reduced, and fuel consumption can be reduced.

또한, 상기 축열식버너부에서 분사된 고온의 연소가스가 턴디쉬(1) 내부의 댐(6) 사이를 통과하여 다른 쪽의 축열식버너부로 흐르면서 턴디쉬(1) 내부를 골고루 가열시키게 되고, 이러한 작용이 일정 주기로 흐름방향이 바뀌면서 이루어지므로 종래의 방법에 의한 턴디쉬 가열의 경우보다 훨씬 균일한 턴디쉬(1) 가열 결과를 얻을 수 있게 된다.In addition, the hot combustion gas injected from the regenerative burner part passes through the dam 6 inside the tundish 1 and flows to the other regenerative burner part to heat the inside of the tundish 1 evenly. Since the flow direction is changed at regular intervals, it is possible to obtain a more uniform tundish 1 heating result than in the case of tundish heating by the conventional method.

한편, 일정시간이 흐른 다음 상기 절환밸브(7)의 전환에 의해 배기모드에 있던 B 및 D측 축열식버너 본체(4)가 연소모드로 바뀌면서 연소가스가 반대 방향으로 턴디쉬(1) 내부를 흐르면서 상기 턴디쉬(1)를 가열시키고 당초 연소모드에 있던 A 및 C측) 축열식버너 본체(4)를 통해 축열체(5)를 가열시킨 다음 절환밸브(7)를 거쳐 배기되며, 이때 상기 절환밸브의 V2, V4는 오픈된 상태이고, V1, V3는 클로즈된 상태이다.On the other hand, after a certain period of time, the B and D-side regenerative burner main body 4 in the exhaust mode is switched to the combustion mode by switching of the switching valve 7, while the combustion gas flows inside the tundish 1 in the opposite direction. The tundish 1 is heated and the heat accumulator 5 is heated through the regenerative burner body 4 in the A and C side, which was originally in the combustion mode, and then exhausted through the switching valve 7. V2 and V4 are in an open state, and V1 and V3 are in a closed state.

이와 같은 과정에서 상기 댐퍼(9)를 이용하여 턴디쉬(1)의 내부 압력을 ±0 ㎜ Aq가 되도록 조절하여 축열식버너 본체(4)와, 턴디쉬 커버(2) 사이의 틈새를 통해 차가운 공기가 침입하거나, 고온의 노내 연소가스나 화염이 턴디쉬(1) 밖으로분출되는 것을 방지할 수 있다.In this process, by using the damper (9) to adjust the internal pressure of the tundish (1) to ± 0 mm Aq to cool air through the gap between the regenerative burner body (4), the tundish cover (2) Can be prevented from entering, or the high temperature furnace combustion gas or flame is blown out of the tundish 1.

즉, 본 발명에서는 1쌍의 축열식버너부가 일정시간 동안 연소한 후 다른 1쌍의 축열식버너부가 연소될 때 배기모드로 전환되어 배기가스가 통과되고, 상기 축열체(5)를 통해 연소공기와 고온의 배기가스가 교대로 흐르면서 서로 열교환이 이루어지며, 상기 절환밸브(7)를 통해 일정 주기에 따라 전술한 연소와 배기 과정이 반복되고, 상기 댐퍼(9)를 통해 턴디쉬(1)의 기밀이 유지될 수 있다.That is, in the present invention, when one pair of regenerative burners burns for a predetermined time, when the other pair of regenerative burners burns, the gas is converted into an exhaust mode and exhaust gas passes through the regenerative body 5. The exhaust gas flows alternately and the heat exchange is carried out, the above-described combustion and exhaust process is repeated according to a predetermined cycle through the switching valve (7), the airtight of the tundish (1) through the damper (9) Can be maintained.

이상과 같이 본 발명에 따른 열손실 방지를 위한 턴디쉬 가열장치를 예시된 도면을 참조로 설명하였으나, 본 명세서에 개시된 실시예와 도면에 의해 본 발명은 한정되지 않으며 그 발명의 기술사상 범위내에서 당업자에 의해 다양한 변형이 이루어질 수 있음은 물론이다.As described above, the tundish heating apparatus for preventing heat loss according to the present invention has been described with reference to the illustrated drawings. However, the present invention is not limited by the embodiments and drawings disclosed herein, and is within the technical scope of the present invention. Of course, various modifications may be made by those skilled in the art.

상기한 바와 같은 본 발명의 열손실 방지를 위한 턴디쉬 가열장치는 종래 대기중으로 배출되던 고온의 배기가스 손실열을 연소공기의 예열에 활용함으로서 턴디쉬의 열손실 방지와 함께 턴디쉬를 가열하는데 소요되는 연료의 사용량을 절감할 수 있고, 고온의 배기가스가 일정 주기로 방향을 전환하면서 상기 턴디쉬 내부를 흐르면서 내화물을 가열시킴에 따라 턴디쉬 길이방향의 온도편차 발생을 감소시키는 효과가 있다.The tundish heating apparatus for preventing heat loss of the present invention as described above is required to heat the tundish with the prevention of heat loss of the tundish by utilizing the heat of the high-temperature exhaust gas discharged into the atmosphere for preheating the combustion air. The amount of fuel used can be reduced, and the temperature of the tundish in the longitudinal direction can be reduced by heating the refractory while flowing the inside of the tundish while changing the direction of the hot exhaust gas at a predetermined cycle.
