Description

혼선차내 용선량 측정장치 및 그 방법{Apparatus for measuring quantity of pig iron in the TLC and method thereof}Apparatus for measuring quantity of pig iron in the TLC and method

본 발명은 혼선차내 용선량 측정장치에 관한 것이며, 특히, 고로에서 출선되는 용선을 받아서 제강라인 등으로 효율적으로 이동시키기 위해 사용되는 혼선차내에 적재되는 용선량을 측정하는 장치에 관한 것이다. 또한, 본 발명은 혼선차내 용선량을 측정하는 방법에 관한 것이기도 하다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for measuring molten iron capacity in a crossroad vehicle, and more particularly, to an apparatus for measuring a molten iron amount loaded in a crossroad vehicle used to receive a molten iron drawn out of a blast furnace and efficiently move it to a steelmaking line. The present invention also relates to a method for measuring the amount of molten iron in the crossroad vehicle.

도 1 및 도 2에 도시된 바와 같이, 혼선차(1 ; 토페도카)는 용선을 저장할 수 있어야 하기 때문에 그 재질은 일반적으로 고온에 강한 내화벽돌(3)로 적층되고, 그 바깥쪽은 금속(2)으로 이루어져 있다. 또한, 혼선차(1)는 목적지에 도달하면 그 자체를 기울여 용선(4)을 배출할 수 있는 구조로 되어 있다.As shown in Figs. 1 and 2, the crosstalk difference (1; topedoca) should be able to store molten iron, so that the material is generally laminated with a refractory brick (3) resistant to high temperatures, and the outside thereof is made of metal. It consists of (2). In addition, the crossroad car 1 has a structure which can incline itself and discharge the molten iron | metal 4 when reaching the destination.

이렇게 혼선차(1)가 구성되어 있기 때문에, 혼선차내의 용선량을 실측하기는 사실상 곤란하다. 그러나, 정확한 용선량을 측정하는 것은 제선공정 및 제강공정에서 매우 중요한 사항이므로, 여러가지 방법으로 혼선차내 용선량을 측정하고 있다.Since the crosstalk difference 1 is comprised in this way, it is difficult to actually measure the molten iron | metal amount in a crosstalk difference. However, since the accurate measurement of the molten iron dose is very important in the steelmaking process and the steelmaking process, the molten iron in the crosstalk vehicle is measured by various methods.

그 중에서, 도 2에 도시된 바와 같이, 용선(4)을 담은 혼선차(1)의 상부에 고정된 측정센서(5)를 사용하여 용선면까지의 거리를 측정하고 미리 데이터 베이스화된 자료, 즉 거리대 혼선차 내부부피의 식에 철비중을 곱하여 용선량을 측정하는 방법을 많이 사용되고 있다. 그러나, 도 2의 용선량 측정방법은 고온의 용선에 의한 혼선차내의 마모, 슬래그의 증가로 인한 혼선차 내부공간의 변화를 알 수 없어 용선량을 정확하게 측정할 수가 없다.Among them, as shown in FIG. 2, the distance to the molten iron surface is measured using a measuring sensor 5 fixed on the upper portion of the crosstalk difference 1 containing the molten iron 4, and the data, which is previously databased, that is, Many methods have been used to measure the amount of molten iron by multiplying the ratio of the inner volume of the cross-over crossroads by the iron ratio. However, in the method of measuring the molten iron dose of FIG. 2, it is not possible to accurately measure the molten iron amount due to a change in the internal space of the crosstalk vehicle due to wear in the crosstalk vehicle due to hot molten iron and an increase in slag.

그리고, 최근에는 도 3에 도시된 바와 같이 적외선 카메라, 라인 스캔카메라(6) 등을 혼선차(1) 내부를 전체적으로 관찰할 수 있는 거리에 고정하고 한 방향으로 스캔(또는 회전)하여 용선을 제외한 부분의 부피를 계산한 후, 실제 혼선차의 최대 부피에서 감한 다음 철비중을 곱하여 실제 용선량을 계측해 보려고시도하고 있는 실정이다. 그러나, 도 3의 용선량 측정방법은 고온의 용선 가까이에서 정상적으로 동작가능한 시스템(적외선 카메라, 라인 스캔카메라 등등)을 구성하기가 매우 힘들뿐만 아니라, 내부 표면적의 모든 지점이 노출되지 않을 경우에는 상당한 오차를 동반하는 문제점이 있다. 또한, 실제 측정값과 혼선차의 내부에 불순물 등이 융착되어 성장(지검의 성장)하는 등 내부의 형상을 예측하기 힘들기 때문에, 현재 대략 혼선차의 최대용량 320톤 중에서 약 260~280톤 정도만 적재함으로 운전 중인 혼선차의 사용대수가 증가하여 비효율적이다.In addition, as shown in FIG. 3, an infrared camera, a line scan camera 6, and the like are fixed at a distance at which the inside of the crosstalk vehicle 1 can be observed as a whole, and scanned (or rotated) in one direction to remove the molten iron. After calculating the volume of the part, it is subtracted from the maximum volume of the actual crosstalk difference, and then attempts to measure the actual amount of molten iron by multiplying the specific gravity. However, the method of measuring the melt dose of FIG. 3 is not only very difficult to construct a system (infrared camera, line scan camera, etc.) that can operate normally near a hot molten iron, but also a significant error when all points of the inner surface area are not exposed. There is a problem accompanying. In addition, since it is difficult to predict the internal shape such as the actual measurement value and the growth of impurities such as fusion of the inside of the crossover car (growth of a finger), currently, only about 260-280 tons of the maximum capacity of the crossover car is 320 tons. It is inefficient because the number of used crossroad cars in the loading box is increased.

따라서, 본 발명은 앞서 설명한 바와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 로드셀을 이용하여 용선적재 전후의 무게를 정확하게 측정하고 이를 연산하여 용선량을 측정함으로써 그 양을 정확하게 측정할 수 있는 혼선차내 용선량 측정장치 및 그 방법을 제공하는 데 그 목적이 있다.Therefore, the present invention has been made in order to solve the problems of the prior art as described above, by accurately measuring the weight before and after the molten iron loading using a load cell and by calculating the amount of molten iron to calculate the amount can be accurately measured It is an object of the present invention to provide a molten iron dose measuring apparatus and method therefor.

도 4에 보이듯이, 본 발명의 혼선차내 용선량 측정장치는 혼선차(1)의 양 단부쪽을 지지하는 양 주축 하단부에 부착되는 로드셀(7 ; Load cell)과, 혼선차(1)가 용선을 적재할 수 있는 정위치에 정지하거나 혼선차(1)내 용선적재가 완료되어 혼선차(1)가 정위치에서 이동하는 것을 감지하는 위치감지센서(도시안됨)와, 이런 위치감지센서의 작동시에 로드셀(7)에서 각각 측정한 하중값을 무선으로 주운전실로 전송하는 전송부(8)와, 이런 전송부(8)에서 전송한 하중값을 주운전실에서 각각 수신하는 수신부(9) 및, 이런 수신부(9)에서 수신한 하중값을 기반으로 혼선차내 용선량을 연산하는 연산부(10)로 구성되어 있다.As shown in FIG. 4, the apparatus for measuring the molten iron dose in the crosstalk vehicle according to the present invention includes a load cell 7 attached to the lower end portions of both main shafts supporting both ends of the crosstalk vehicle 1, and the crosstalk vehicle 1 is molten iron.

본 발명의 전송부(8)는 위치감지센서의 신호, 즉 혼선차(1)가 용선을 적재하는 정위치에서 정지하거나 용선적재후 이동할 때의 위치감지센서의 신호를 각각 받아 그 때 로드셀(7)에서 각각 측정한 하중값을 수신부(9)에 각각 전송한다.The transmitting unit 8 of the present invention receives the signal of the position sensor, that is, the signal of the position sensor when the crosstalk vehicle 1 stops at the correct position to load the molten iron or moves after the molten iron is loaded. Are transmitted to the receiver 9, respectively.

아래에서는, 앞서 설명한 바와 같이 구성된 본 발명의 혼선차내 용선량 측정장치를 통한 그 측정방법에 대해 상세히 설명하겠다.In the following, it will be described in detail with respect to the measuring method through the molten iron dose measurement apparatus in the cross-talk vehicle of the present invention configured as described above.

먼저, 양 주축 하단부에 부착된 로드셀(7)에 혼선차(1)의 양 단부가 각각 위치하여 혼선차(1)가 용선을 적재할 수 있는 정위치에 정지하면, 위치감지센서가 혼선차(1)의 위치를 감지한다. 그러면, 전송부(8)에서는 양 주축의 단부에 위치하는 로드셀(7)에서 측정된 각각의 하중값을 무선으로 주운전실의 수신부(9)로 전송한다. 그러면, 수신부(9)에 연결된 연산부(10)에서는 수신한 2개의 하중값을 합산하여 혼선차(1)의 초기무게(A), 즉 혼선차(1)내 용선이 전혀 적재되지 않은 상태의 혼선차(1)의 무게를 저장한다.First, when both ends of the cross talk car 1 are located in the load cells 7 attached to the lower ends of both spindles, respectively, and the cross talk car 1 stops at the correct position where the molten iron can be loaded, the position detecting sensor is the cross talk car ( 1) detect the position of. Then, the transmission part 8 transmits each load value measured by the load cell 7 located in the edge part of both main shafts to the receiving part 9 of the main cab by radio. Then, the calculating unit 10 connected to the receiving unit 9 adds the two received load values to the initial weight A of the crosstalk difference 1, that is, the crosstalk state in which the molten iron in the crosstalk difference 1 is not loaded at all. The weight of the car 1 is stored.

그리고, 혼선차(1)내 용선적재가 시작되고 현재의 용선적재레벨을 측정하는 센서의 출력값에 따라 용선적재가 중지하여, 혼선차(1)의 이동이 위치감지센서에 의해 감지되면, 전송부(8)에서는 양 주축의 단부에 위치하는 로드셀(7)에서 측정된 각각의 하중값을 무선으로 주운전실의 수신부(9)로 전송한다. 그러면, 수신부(9)에 연결된 연산부(10)에서는 수신한 2개의 하중값을 합산하여 혼선차(1)의 적재무게(B), 즉 혼선차(1)내 용선이 적재되어 있는 상태의 혼선차(1)의 무게를 입력받아, 적재무게(B)에서 초기무게(A)를 감하여 혼선차(1)내 용선량을 계산한다. 이런 과정을 통해 혼선차(1)내 적재된 용선량을 정확하게 측정하게 된다.When the molten iron is loaded in the crossroad difference vehicle 1 and the molten iron load is stopped according to the output value of the sensor measuring the current molten iron level, and the movement of the crossroad vehicle 1 is detected by the position detecting sensor, the transmission unit In (8), each load value measured by the load cell 7 located at the ends of both main shafts is wirelessly transmitted to the receiver 9 of the main cab. Then, the calculation unit 10 connected to the receiving unit 9 adds the two received load values to the loading weight B of the crosstalk difference 1, that is, the crosstalk difference in the state where the molten iron in the crosstalk difference 1 is loaded. Taking the weight of (1), subtract the initial weight (A) from the loading weight (B) to calculate the dissolved dose in the crosstalk difference (1). Through this process, it is possible to accurately measure the amount of molten iron loaded in the crosstalk vehicle (1).

또한, 본 발명의 혼선차내 용선량 측정장치는 로드셀(7)을 이용하여 용선량을 정확하게 측정하고 그에 따른 혼선차내 적재정도를 파악할 수 있기 때문에, 혼선차내 용선의 적재량을 조절할 수 있는 근거를 제공한다. 즉, 혼선차내 적재정도에 따른 용선량을 파악함으로써, 혼선차내에 용선을 최대한 적재할 수가 있다.In addition, since the molten iron dose measuring apparatus in the crossroad vehicle of the present invention can accurately measure the molten amount using the load cell (7) and grasp the loading degree in the crossroad vehicle accordingly, it provides a basis for adjusting the loading amount of the molten iron in the crossroad vehicle. . That is, by grasping the amount of molten iron according to the degree of loading in the crossroad vehicle, the molten iron can be loaded as much as possible in the crossroad vehicle.

또한, 본 발명의 혼선차내 용선량 측정장치는 로드셀(7)을 이용한 무게측정법을 이용하기 때문에, 혼선차(1) 내부에 불순물 등이 융착되어 성장(지검의 성장)하는 것을 무게변동에 따라 예측할 수가 있다.In addition, since the molten iron dose measuring apparatus of the crosstalk vehicle of the present invention uses a weighing method using a load cell 7, it is possible to predict that the impurities (fused with the inside of the crosstalk vehicle 1) are fused and grow (growth of a finger) according to the weight variation. There is a number.
