Description
본 발명은 고로에서 배출된 용융물을 운송하는 차량(Torpedo Ladle Car:TLC)에 수선하는 용선량을 측정하는 TLC 평량기의 수선 용량을 자동으로 판별하고 제어하는 방법에 관한 것으로서, 보다 상세하게는 수선용량이 각각 상이한 TLC의 수선용량을 자동설정하여 정해진 고로 공장에 무관하게 사용할 수 있어서 설비를 효과적으로 운용할 수 있으며, 고로 공장 입구에 검사용 평량 로드셀을 설치하여 비교검사함으로써 평량의 신뢰성을 확보할 수 있는 TLC 평량기의 수선량 자동판별 및 제어방법에 관한 것이다.The present invention relates to a method for automatically determining and controlling the repair capacity of a TLC weighing machine that measures the amount of molten iron to be repaired in a vehicle carrying a melt discharged from a blast furnace (Torpedo Ladle Car: TLC), and more specifically, By automatically setting the repair capacity of each TLC with different capacity, it can be used regardless of the blast furnace plant, so it is possible to operate the equipment effectively.The reliability of the basis weight can be secured by installing the basis weight load cell for inspection at the entrance of the blast furnace plant. The present invention relates to a method for automatically determining and controlling the dose of a TLC weighing machine.
일반적으로 고로 조업에 있어서는 도 1에 도시되어 있듯이, 고로(1)의 출선구에서 배출된 용선은 탕도를 통해 경주통(3)을 경유하여 레일(5) 위를 이동하여 후공정으로 용융물을 운반하는 TLC(4) 내에 수선하고, TLC 하부에 설치된 평량 로드셀(Load Cell)(6)을 통해 수선량을 측정하여 평량제어기(M.P 100W)(10)에 데이터 신호를 전송하면, 평량제어기 통합시스템(Master Piece 240)(11)에 전송하여 가공후 평량치를 산출하고 제어를 실시하며 연산 및 검출된 신호를 비지니스 컴퓨터(12)와 프로세스 컴퓨터(13)를 경유하여 표시부(14)에 나타내도록 되어 있다. 이때, 해당 TLC(4)의 평량 설정치에 도달한 TLC는 용선을 후공정인 제강공장으로 운반하도록 보내진다.In general, in the blast furnace operation, as shown in FIG. 1, the molten iron discharged from the exit of the blast furnace 1 moves on the rails 5 via the raceway 3 through the ballway to transfer the melt in a post process. After repairing in the transport TLC (4), measuring the amount of repair through the basis weight load cell (Load Cell) 6 installed in the lower TLC and transmits the data signal to the basis weight controller (MP 100W) 10, the basis weight controller integrated system (Master Piece 240) (11) to calculate the basis weight value after processing, perform the control and display the calculated and detected signal on the display unit 14 via the business computer 12 and the process computer 13 . At this time, the TLC which has reached the basis weight set value of the TLC 4 is sent to transport the molten iron to a steelmaking plant which is a post-process.
그런데, 상기와 같이 이루어지는 고로에서 배출된 용선의 운반 조업에 있어서는 용융물을 수선하는 TLC(4)가 고로 공장에서는 100여대가 사용되어 각 종류별로 수선 용량이 달리 설정되어 있고(예컨대, 25대의 1기 TLC는 수선용량이 270톤, 25대의 2기 TLC는 수선용량이 300톤, 25대의 3기 TLC는 수선용량이 350톤, 25대의 4기 TLC는 수선용량이 400톤, 25대의 5기 TLC는 수선용량이 450톤등,..), 공장별로 정해진 TLC(4)가 사용되므로 설비 가동 측면에서 능률이 저하하며, TLC 부족시 용선의 처리가 곤란하여 설비가동을 중단하지 않을 수 없다.By the way, in the transport operation of the molten iron discharged from the blast furnace as described above, about 100 TLC (4) for repairing the melt is used in the blast furnace factory, the repair capacity is set differently for each type (for example, 25 units TLC has a repair capacity of 270 tons, 25 two TLCs have a repair capacity of 300 tons, 25 three TLCs have a repair capacity of 350 tons, and 25 four TLCs have a repair capacity of 400 tons and 25 five TLCs Repair capacity is 450 tons, etc.), TLC (4) is used for each plant, which reduces efficiency in terms of equipment operation.
또한, TLC의 수선량을 검출하기 위한 평량 로드셀(6)이 레일(5) 하부의 지하에 설치되어 검출된 데이터의 신뢰성이 떨어져 평량치에 오차가 빈번하게 발생하므로 운전가가 TLC의 수선량을 눈으로 측정하여 수선 설정량에 도달 여부를 판단하므로 평량 작업이 비효율적이었다.In addition, since the basis weight load cell 6 for detecting the repair amount of the TLC is installed in the basement under the rail 5, the reliability of the detected data is inferior, and errors occur frequently in the basis weight value. As a result, it was judged whether the repair set amount was reached and the basis weight operation was inefficient.
따라서, 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 이루어진 것으로서, 서로 다른 수선 용량을 갖는 TLC의 설정된 용량치와 검출된 수선 용량을 비교판별하여 수선용량을 결정하고 수선량 검출의 신뢰도를 제고하고 평량기 이상시 신속히 대처할 수 있도록 한 고로 용융물 운반설비의 수선 용량 자동 판별 및 제어방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, to determine the repair capacity by comparing the detected capacitance with the set capacitance value of the TLC having different repair capacity, and to determine the reliability of the detection of the repair dose The purpose of the present invention is to provide a method for automatically identifying and controlling the repair capacity of the blast furnace melt conveying equipment, which can be improved and promptly responded to an error in the weighing machine.

It is configured to transmit the detected data to the basis weight controller integrated system 11 via (10).
또한, 도 3 도시와 같이, 각각의 TLC에는 고유 용량을 검출하도록 검출센서(8-1,...,8-6)를 설치하고, TLC 정위치에는 검출센서(8-11,8-22,...,8-66)를 설치하여 서로 다른 수선 용량을 갖는 TLC의 수선용량을 검출하여 평량제어기(10)에 전송하도록 구성하여 어느 고로 공장에서나 서로 다른 용량을 갖는 TLC를 용이하게 선택하여 사용함으로써 작업능률을 향상시키도록 한다.In addition, as shown in Fig. 3, each TLC is provided with detection sensors 8-1, ..., 8-6 to detect the intrinsic capacitance, and the detection sensors 8-11, 8-22 are positioned at the TLC positions. , ..., 8-66) to detect the repair capacity of the TLC with different repair capacity and transmit it to the basis weight controller 10 to easily select the TLC with different capacity in any blast furnace factory. Use to improve work efficiency.
한편, 도 4 도시와 같이, 본 발명에서는 종래와 달리 주상 TLC 평량기 제어시스템을 구성함에 있어서 평량제어기(10)에 연산부(20)를 전기적으로 연결하여, 관제실(16)에서 부여된 번호에 따라 입력설정된 수선용량과 검출센서(8-1,..8-6)를 통해 검출된 고유 수선용량을 비교하여 수선량을 설정하고, 검사용 로드셀(7-1,...,7-4)로부터 평량제어기(10)에 전송된 데이터에 의해 수선용량을 검사하여 상용 로드셀(6-1,..6-4)로부터의 데이터와 비교하도록 하고 있다.On the other hand, as shown in Figure 4, in the present invention, unlike in the conventional configuration of the columnar TLC weighing machine control system by electrically connecting the calculation unit 20 to the basis weight controller 10, according to the number given in the control room 16 The repair dose is set by comparing the input repair capacity with the intrinsic repair capacity detected through the detection sensors 8-1, .. 8-6, and the inspection load cells 7-1, ..., 7-4. The repair capacity is checked by the data transmitted to the basis weight controller 10 and compared with the data from the commercial load cells 6-1, .. 6-4.
그리고 본 발명에서는 각각의 TLC(4)에 정위치를 검출하기 위한 센서(17,17-1)를 설치한다.In the present invention, sensors 17 and 17-1 for detecting the correct position are provided in each TLC 4.
다음에는 도 5와 관련하여 상기와 같이 구성된 주상 TLC 평량 제어시스템을 통한 본 발명의 주상 TLC 평량제어방법을 설명한다.Next, the columnar TLC basis weight control method of the present invention through the columnar TLC basis weight control system configured as described above with reference to FIG. 5 will be described.
고로 공장의 출선 작업 예상 시간에 다음 출선구에 예비 TLC를 선택하여(38) 차입후, 차입된 TLC에 대해 관제실에서 고유번호를 지정받으며(39,40), 이 지정된 고유번호를 비지니스 컴퓨터에 입력하면(41), 프로세스 컴퓨터(42)로 전송되어 표시부(14)에 표시된다.Therefore, at the expected time of starting work at the blast furnace, the preliminary TLC is selected at the next exit (38), and the borrowed TLC is assigned a unique number at the control room (39,40), and the specified unique number is input to the business computer. The lower surface 41 is transmitted to the process computer 42 and displayed on the display unit 14.
이어서, 고유 수선용량에 대한 신호는 평량제어기 통합시스템(11)을 경유하여 평량제어기(10)에 입력되고(43,44), 이 평량제어기(10)에서는 검출센서(8-11,..8-66)로부터의 TLC 고유용량 검출신호 데이터를 입력받아 입력된 고유 수선용량과 비교하여 비교치가 상이하면 경보를 발생하고(61), 정상일 경우 수선량을 설정한다(이때, 검출된 수선 용량이 400톤일 경우 기존의 데이터 베이스의 어드레스를 400으로 변경하는 식이다)(46).Subsequently, a signal for the intrinsic repair capacity is input to the basis weight controller 10 via the basis weight controller integrated system 11 (43, 44), and the basis weight controller 10 detects the sensors 8-11, ..8 TLC high capacitance detection signal data from -66) is inputted and an alarm is generated when the comparison value is different from the input intrinsic repair capacitance (61), and if it is normal, the repair amount is set (at this time, the detected repair capacitance is 400). In the case of a tone, the address of an existing database is changed to 400) (46).
이와 같이, 수선량을 설정후 출선을 개시하며(47), 용선을 평량하여(48) 수선 작업을 종료하는 것이다.In this way, after setting the repaired amount, starting line is started (47), the molten iron is basis weighted (48), and the repair work is finished.
한편, 다음에는 TLC의 수선량 평량 작업을 설명하면, 고로 공장 입구 레일에 설치된 검사용 로드셀(7-1,..7-4)의 정위치에 TLC가 진입하여 정위치 진입신호가검출되면(52), 현재의 수선량을 검출하여 평량제어기(10)에 전송한다(53,54).On the other hand, the following is a description of the TLC repair dose basis, when the TLC enters the correct position of the inspection load cell (7-1, .. 7-4) installed in the blast furnace factory entrance rail is detected the exact position entry signal ( 52, the current repair amount is detected and transmitted to the basis weight controller 10 (53, 54).
다음에는 상용 로드셀의 정위치(17,17-1)로 TLC를 이동시켜 평량하여(55,56,57), 비교치가 상이(±0.5톤 이상)하면 경보를 발생한다(60).Next, the TLC is moved to the normal position (17, 17-1) of the commercial load cell and weighed (55, 56, 57). If the comparison value is different (± 0.5 tons or more), an alarm is generated (60).
따라서, 상기 설명한 바와 같은 본 발명에 의하면, 고로 공장에 사용되는 100여대의 수선용량이 각각 상이한 TLC의 수선용량을 자동설정하여 정해진 고로 공장에 무관하게 사용할 수 있어서 설비를 효과적으로 운용할 수 있으며, 고로 공장 입구에 검사용 평량 로드셀을 설치하여 비교검사함으로써 평량의 신뢰성을 확보할 수 있다.Therefore, according to the present invention as described above, the repair capacity of about 100 TLC used in the blast furnace plant can automatically set the repair capacity of each different TLC can be used irrespective of the blast furnace plant, it is possible to operate the equipment effectively, By installing a basis weight load cell for inspection at the factory entrance, it is possible to ensure the reliability of basis weight.
