Description
본 고안은 턴디시의 예열장치에 관한 것으로, 특히 턴디시 내의 상부에 설치되는 예열버너의 불꽃이 턴디시의 내부 바닥에 보다 많이 접촉되면서 불꽃의 간접예열구역을 적게 하는 동시에 직접예열구간을 넓힘으로써 예열 효과를 극대화시킨 턴디시의 예열장치에 관한 것이다.The present invention relates to a preheating device of the tundish, and in particular, the flame of the preheat burner installed in the upper part of the tundish is more in contact with the inner bottom of the tundish, thereby reducing the indirect preheating zone of the flame and widening the direct preheating section. It relates to a preheating device of the tundish to maximize the preheating effect.
일반적으로 연속주조작업시 용강을 담는 중간용기인 턴디시는 주조초기에 용강을 담기 위해서 용강온도(1500~1600℃)와 근접한 온도(1200~1300℃)까지 예열되어야 하고, 이로써 용강온도가 보상된다.In general, the tundish, which is an intermediate container for molten steel in continuous casting operation, needs to be preheated to a temperature close to molten steel (1500 ~ 1600 ℃) (1200 ~ 1300 ℃) in order to contain molten steel at the beginning of casting, thereby compensating molten steel temperature. .
여기서 도1에 도시한 바와 같이 종래의 턴디시 예열버너(4)는 각각 1개의 화구(6)가 설치되어 있고, 각 화구마다 방열커버(3)가 설치되면서 예열작업시 불꽃의 외부 방출을 방지하게 된다.Here, as shown in FIG. 1, the conventional tundish preheat burner 4 is provided with one crater 6, and a heat dissipation cover 3 is provided for each crater, thereby preventing external emission of sparks during the preheating operation. Done.
그러나 평균적으로 3시간 소요되는 종래의 턴디시(1) 예열은 턴디시(1)의 바닥에 대하여 수직되도록 설치되는 각 버너(4)의 화구(6)에 의해 이루어지는데, 이때 화구의 불꽃이 턴디시의 바닥에 접촉되면서 예열되어 직접예열면적이 적은 반면에 간접예열면적이 많게 된다.However, on average, three hours of preheating of the conventional tundish 1 is carried out by the crater 6 of each burner 4 which is installed to be perpendicular to the bottom of the tundish 1, in which the flame of the crater is turned. When it comes into contact with the bottom of the dish, it is preheated, so that the direct preheating area is small while the indirect preheating area is high.
따라서 턴디시(1)를 적정온도까지 상승 예열시키는데 걸리는 시간이 과다 소용되고, 이에 따라 예열버너(4)의 가스사용량이 증가되면서 방열커버(3)가 쉽게 산화소손되며, 소손된 방열커버의 교환으로 원가가 상승되는 문제점이 발생된다.Therefore, the time taken to warm up the tundish 1 to an appropriate temperature is excessively used. Accordingly, as the gas usage of the preheat burner 4 is increased, the heat dissipation cover 3 is easily oxidized and replaced. This raises the problem of rising costs.
본 고안은 예열불꽃이 턴디시의 바닥에 가능한한 많이 접촉되도록 형성되어 직접예열면적을 넓히면서 간접예열면적을 적게함으로써 열효율을 향상시키고, 짧은 시간내에 예열을 완료할 수 있으며, 방열커버의 수명을 연장할 수 있는 턴디시의 예열장치를 제공함에 그 목적이 있다.The present invention is formed so that the preheat flame is as much as possible to contact the bottom of the tundish as possible to increase the direct preheating area and reduce the indirect preheating area to improve thermal efficiency, complete the preheating in a short time, and extend the life of the heat dissipation cover It is an object of the present invention to provide a preheating device of a tundish.

상기한 목적을 달성하기 위하여 본 고안은 턴디시의 상면에 설치되면서 용강주입구 및 다수의 버너취부홈이 형성되는 턴디시커버와 ; 상기 버너취부홈에 의해 형성되는 홀에 삽입되면서 상기 턴디시에 내장되는 하부에 다수의 화구를 갖는 버너화구가 형성되는 예열버너로 구성되는 것을 특징으로 하는 턴디시의 예열장치를 제공한다.In order to achieve the above object, the present invention has a tundish cover installed on the upper surface of the tundish and a molten steel inlet and a plurality of burner mounting grooves are formed; It is inserted into a hole formed by the burner mounting groove provides a preheating device of the tundish, characterized in that consisting of a preheat burner having a burner crater having a plurality of craters in the lower portion embedded in the tundish.
도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.

먼저 3개의 조각으로 분리되어 턴디시(1)의 상면에 설치되는 턴디시커버(12)는 접합면의 중앙부에 각각 반원 형상의 버너취부홈(13)이 형성되어 있고, 특히 3개의 조각편중 가운데에 위치하는 턴디시커버에는 편향되게 용강주입구(14)가 형성되어 있다.First, the tundish cover 12, which is divided into three pieces and installed on the top surface of the tundish 1, has a semicircular burner mounting groove 13 formed at the center of the joining surface, and in particular, among the three pieces. The molten steel injection hole 14 is formed in the tundish cover located in the deflector.
그리고 턴디시커버(12)의 접합부에 버너취부홈(13)에 의해 형성되는 2개의 원형홀에 각각 상부가 외장되도록 삽입되는 예열버너(4)는 상면에 가스 및 에어흡입관(5)이 연결되어 있고, 턴디시에 내장되는 하부에 버너화구(11)가 연통되도록 설치되어 있다.In addition, the preheat burner 4 is inserted into the two circular holes formed by the burner mounting groove 13 at the junction portion of the tundish cover 12 so that the upper part is externally connected to the gas and air suction pipe 5. The burner crater 11 is installed in a lower portion built in the tundish.
여기서 대략 ∧ 형상으로 형성되는 버너화구(11)는 2개의 화구의 사이각이 45°로 형성되면서 턴디시(1)의 내측 바닥면과 예각을 이루도록 설치되어 있고, 필요에 따라 3개 이상의 화구 형성도 가능하다.Here, the burner crater 11 formed in the shape of an approximate shape is provided to form an acute angle with the inner bottom surface of the tundish 1 while the angle between the two craters is formed at 45 °, and three or more craters are formed as necessary. It is also possible.
이때 턴디시(1)의 예열작업시 버너취부홈(13)의 내주면과 예열버너(4)의 외주면 사이의 틈으로 버너의 불꽃이 방출되는 현상을 방지하기 위하여 방열커버(3)가 턴디시커버(12)의 상면에 접하도록 설치되어 있다.At this time, during the preheating operation of the tundish 1, the heat dissipation cover 3 is a tundish cover in order to prevent the flame of the burner from being emitted into the gap between the inner circumferential surface of the burner mounting groove 13 and the outer circumferential surface of the preheat burner 4. It is provided in contact with the upper surface of (12).
이하 본 고안의 작용을 설명한다.Hereinafter will be described the operation of the present invention.
먼저 예열버너(4)에 가스 및 에어흡입관(5)을 통해 가스와 에어가 공급되면 버너화구(11)를 통해 턴디시(1) 내측 바닥에 불꽃이 공급되는데, 이때 버너화구의 2개의 화구는 각각 턴디시의 바닥과 예각을 이루도록 형성되어 직접예열범위가 광범해진다.First, when gas and air are supplied to the preheat burner 4 through the gas and air suction pipe 5, the flame is supplied to the inner bottom of the tundish 1 through the burner crater 11, wherein two craters of the burner crater are Each is formed to form an acute angle with the bottom of the tundish, thereby widening the direct preheating range.
즉, 버너화구(11)의 2개의 화구를 통해 분출되는 예열불꽃이 턴디시(1)의 내측 바닥에 예각으로 닿게되어 직접예열구역을 넓히는 반면에 간접예열구역을 줄이어 열효율이 향상된다.That is, the preheating flame ejected through the two craters of the burner crater 11 acutely reaches the inner bottom of the tundish 1 to widen the direct preheating zone while reducing the indirect preheating zone to improve thermal efficiency.
여기서 버너화구(11)의 화구를 3개 이상 설치할 경우 직접예열구역이 넓어지는 반면에 예열불꽃이 약해지는 단점이 발생되므로 화구의 수는 예열불꽃의 세기를 고려하여 설치하여야 한다.Where more than three craters of burner crater 11 are installed, the preheating zone is widened, while the disadvantage of weakening the preheating flame occurs, so the number of craters should be installed in consideration of the intensity of the preheating flame.
본 고안은 예열불꽃이 턴디시의 바닥에 가능한한 많이 접촉되도록 형성되어 직접예열면적을 넓히면서 간접예열면적을 적게함으로써 열효율을 향상시키고, 짧은 시간내에 예열을 완료할 수 있으며, 방열커버의 수명을 연장할 수 있는 효과를 제공한다.The present invention is formed so that the preheat flame is as much as possible to contact the bottom of the tundish as possible to increase the direct preheating area and reduce the indirect preheating area to improve thermal efficiency, complete the preheating in a short time, and extend the life of the heat dissipation cover It provides an effect that can be done.
